Shrimp farming in India, till 2009, was synonymous with the mono culture of tiger shrimp, Penaeus monodon. About 1,90,000 ha brackishwater area have been developed for shrimp culture in the country spread over all the coastal states. Since 1995 culture of P monodon is affected by White Spot Syndrome Virus (WSSV) and the development of shrimp farming has become stagnant.
Most of the Southeast Asian countries like Thailand, Vietnam, Indonesia were also culturing P. monodon and since 2001-02 onwards most of them have shifted to culture of exotic Whiteleg shrimp,Litopenaeus vannamei because of the availability of Specific Pathogen Free (SPF) and Specific Pathogen Resistant (SPR) broodstock. In India, Pilot-scale introduction of L.vannamei was initiated in 2003 and after a risk analysis study large-scale introduction has been permitted in 2009.

Shrimp aquaculture is an important and valuable production sector that has been growing rapidly over the past two decades. Success is largely based on the quality of post larvae, particularly their health condition, thus making hatchery production of quality post larvae crucial to the sector’s sustainability. Vietnam is the leading producer of black tiger shrimp in the world with a production of 300,000 tons in 2011, followed by India and Indonesia with a production of 187,900 tons and 126,200 tons respectively.
Major contribution of the tiger shrimp to global shrimp production and the economic losses resulting from disease outbreaks, it is essential that the shrimp-farming sector invest in good management practices for the production of healthy and quality seed. The Indian shrimp hatchery industry has established a detailed guidance and protocols for improving the productivity, health management, biosecurity and sustainability of the sector. Following a brief review of shrimp hatchery development in India, the major requirements for hatchery production are discussed under the headings: infrastructure, facility maintenance, inlet water quality and treatment, wastewater treatment, biosecurity, standard operating procedures (SOPS), the Hazard Analysis Critical Control Point (HACCP) approach, chemical use during the hatchery production process and health assessment. Pre-spawning procedures include the use of wild, domesticated and specific pathogen free/ specific pathogen resistant (SPF/SPR) broodstock, broodstock selection and holding techniques, transport, utilization, health screening, maturation, nutrition and spawning, egg hatching; nauplius selection, egg/ nauplius disinfection and washing and holding, disease testing and transportation of nauplii. Post-spawning procedures include: larval-rearing unit preparation, larval rearing/health management, larval nutrition and feed management, important larval diseases, quality testing/selection of PL for stocking, PL harvest and transportation, nursery rearing and record keeping.

CAGE CULTURE OF FISH THEIR TREND,STATUS AND PRODUCTION Ashish sahu
Cage culture is an aquaculture production system where fish are held in Cage. Cage culture of fish utilizes existing water resources but encloses the fish in a cage which allows water to pass freely through the enclosures and the surrounding water body. Cages are used to culture several types of shell fish and finfish species in fresh, brackish and marine waters. Cages in freshwaters are used for food fish culture and for fry to fingerling rearing.
In 1950s modern cage culture began with the initiation of production of synthetic materials for cage construction. Fish production in cages became highly popular among the small or limited resource farmers who are looking for alternatives to traditional agricultural crops. The mesh size of the cage is kept smaller than the fish body. In India cage culture have been attempted first for Air breathing fish. Cage mesh netting made from synthetic material that can resist decomposition in water for a long period of time. Cage are used to culture several type of shell fish and fin fishes in fresh , brackish and marine water. Cage in fresh water are used for food fish culture and for fry to fingerling rearing. Cages are generally small, ranging in freshwater reservoirs from 1 square meter (m2) to 500 m2.

Goats are one of the oldest species of domesticated animals. There are nine species generally accepted as true goats with around three hundred breeds. Many small farmers or backyard raisers have found that they can earn from raising goats. Goats provide milk, meat, fibre,and hide which raisers can sell or use for themselves. If you are willing enough to try raising goats, you can start by raising one to two goats. Goat-raising is not easy but if you also willing to learn more about them, you can confidently raise goats either as pets or as livestock. This quick-start guide will give you basic information about goats and goat-raising.
Goats are herbivores. They fall under the genus Capra. What we know as the domestic goat is a subspecies of the family Bovidae. Goats are closely related to the sheep so that both animals will often exhibit similar traits. If you are serious about raising goats, you should start to memorize terms related to this venture. A female goat is called a “nanny” or “doe” and a young female is called a “doeling”. A mother goat is
referred to as a dam. A male goat is called a “buck” or “billy” and those that have been castrated are “wethers”. A goat offspring is called a “kid”.In Middle Eastern and Asian countries, goats are kept for agricultural purposes or sometimes as pets. In the US, goat-raising is finding its way
to become a fast growing industry.
Dairy farming in India is a profitable business. It provides an excellent opportunity for self employment of unemployed youth. It is also an important source of income generation to small/marginal farmers and agricultural labourers. India is the largest milk producer of the world. The demand of milk & milk product is increasing rapidly. There is immense scope of dairy farming in our country. The increasing cost of feed ingredients and its seasonal variability can be reduced by undertaking fodder cultivation.

Goat farming business is not a new enterprise. Rearing goats is a profitable business. Goat has been rearing since the time immemorial. Generally goat farming means rearing goats for the purpose of harvesting milk, meat and fiber. At present, goat farming has become a profitable business and it requires a very low investment because of its multi-functional utility. Commercial goat farming business is contributing greatly to the economy and nutrition of a country.There are many advantages of goat farming business. You can also raise goats along with your other livestock animals. Goats have been considered as poor man’s cow (mini cow) for the poor people because of it’s immense contribution in rural economy and national income. Goat products like milk and meat is not only nutritious and easily digestible food but also a great source of regular income for the poor, landless and marginal farmers. As goats are small sized animal , so they are easily maintained. Even they are easily maintained and cared by women and children. For successful goat farming business, you need to do some common tasks such as feeding, milking and caring. These simple tasks do not require much equipment, capital, labor or hard work.
Dairying is an important source of subsidiary income to small/marginal farmers and agricultural labourers. In addition to milk, the manure from animals provides a good source of organic matter for improving soil fertility and crop yields. The gobar gas from the dung is used as fuel for domestic purposes as also for running engines for drawing water from well. The surplus fodder and agricultural by-products are gainfully utilised for feeding the animals. Almost all draught power for farm operations and transportation is supplied by bullocks. Since agriculture is mostly seasonal, there is a possibility of finding employment throughout the year for many persons through dairy farming. Thus, dairy also provides employment throughout the year. The main beneficiaries of dairy programmes are small/marginal farmers and landless labourers.To know more please visit us www.growelagrovet.com

Here we are shortly describing the necessary steps for starting goat farming business.
Goat owners need to understand the basic structure and functioning of goats if they are to maintain the health and increase the productivity of their herds. This brief outline of the goat’s anatomy and physiology is a starting point for those who want to begin keeping goats, and for established producers who would like to fine-tune their knowledge. Anatomy is the branch of biological science that deals with the form and structure of animals.
Physiology is the branch that deals with the function of the body
Dairy farmers’ production systems worldwide need to be able to combine profitability with the responsibility of protecting human health, animal health, animal welfare and the environment.Dairy farmers, as the primary producers in the supply chain, should also be given the opportunity to add value to their product by adopting methods of production that satisfy the demands of processors and customers.
This Guide gives individual dairy farmers proactive guidance on how these objectives can be achieved on their farm. The Guide to good dairy farming practice has been written in a practical format for dairy farmers engaged in the production of milk from any dairy species. When adopted, it will support the production and marketing of safe, quality-assured milk and dairy products. The Guide focuses on the relationship between consumer safety and economic, social and environmental management at the farm level.
The Guide contains many individual practices that contribute to good dairy farming
practice, covering the key aspects of animal health, milk hygiene, nutrition, welfare, the
environment and socio-economic management.
These practices have been drawn from best practice guidelines and existing assurance
schemes around the world, and so individual practices will vary in their applicability to various dairying regions. They are not intended to be legally binding and readers are encouraged to select and implement those guidelines that are of relevance to their situation. As such, this Guide aims to provide a genuine framework for dairy farm assurance schemes to be developed globally, giving individual countries and dairy farmers the opportunity to develop schemes that are specific to their needs.
A SEMINAR ON INDUCING AGENTS OF HYPOPHYSATIONKartik Mondal
The precise combination of environmental factors required for maturation, ovulation and spawning.
However, quite often, under farm conditions, the requisite environmental factors are either not available or do not persist for sufficient length of time for spontaneous maturation to occur.
The pioneering discovery of B.A. Houssay (1931) and Von Ihering (1935, 1937, Argentina) that fishes can be induced to spawn by injecting pituitary homogenates has somewhat mitigated the problem.
The principal advantage of this technique, referred to in aquaculture parlance as “Hypophysation.”

One of the prevailing shrimp diseases in Asia now is white feces disease which causes tremendous economic loss. This article explains what it is and possible control measures.
The Asian catfish Pangasius, Pangasianodon hypophthalmus is recognised as a leading aquaculture food fish on world markets. The commercial culture of Pangasius was developed in the mid 1990’s in Vietnam and quickly expanded to production levels of nearly one million tons per year. Other countries including Thailand, Cambodia, Myanmar, Indonesia, Philippines, Bangladesh and India have adapted Pangasius as part of their aquaculture production. Pangasius can be successfully cultured in most tropical regions of the world however countries in the Western Hemisphere have been slow to embrace Pangasius aquaculture, in part, due to the lack of practical knowledge of the species food requirements during the larval and fry stages.

The green water encouraged by the traditional carp farmers in the Far East and then Europe would be rich with live infusoria including cilates and freshwater rotifers for first feeding. The marine fish industry has had to look at marine rotifers and recreating the plankton soup as many larval species are too small to take newly hatched Artemia. The leading research labs using fish in medical and ecotoxicology projects that have relied upon lab-grown Paramecia cultures are revisiting rotifer culture to maximise fry survival rates.

What is diarrhea in cattle and what causes it?
• Diarrhea (purging, scours) can have many causes.
• Possible causes include bacterial and viral infections, certain chemicals, intestinal parasites, poor diet, overfeeding on milk or lush grass, poisonous plants and other toxins, food allergies and even stress.
• In diarrhea, the intestine fails to adequately absorb fluids, and/or secretion into the intestine is increased. Loss of fluids through diarrhea produces dehydration and the loss of certain body salts.
• It causes a change in body tissue composition and severe depression in the animal.
• Death from scours is usually the result of dehydration and loss of body salts rather than invasion of an infectious agent.
• The correct determination of the cause of diarrhea is important in order to take effective preventive measures.
Domestication of the European rabbit probably occurred in monasteries during the Middle Ages. By the middle of the 17th century, rabbits were commonly raised in England and continental Europe. Oryctolagus cuniculus, one of the more successful mammals of the world, is both prolific and adaptable.
Most of the fancy breeds were developed within the past 100 years, and only since the early 1900s have rabbits been raised domestically in the United
States. The first commercial colonies were started in southern California. Meat rationing during World War II gave the infant industry a push. Today, approximately 200,000 people are engaged in some phase of the rabbit business
in the United States, and animals are produced in every state. Meat processors serving major cities market more than 10 million pounds of rabbit meat annually.

मुर्गियों में बीमारियां से बचाव और टीकाकरण :
मुर्गियों में कई तरह की बीमारियां पाई जाती हैं। जैसे पुलोराम, रानीखेत, हैजा, मैरेक्स, टाईफाइड और परजीविकृमी आदि रोग होते हैं। जिससे मुर्गीपालकों को हर साल भारी नुकसान उठाना पड़ता है। बिमारियों से बचाव के लिए समय -समय पर मुर्गियों का टीकाकरण बहुत ही जरुरी है ,कुछ बीमारियां की रोक-थाम केवल टीकाकरण से ही संभव है। मुर्गियों में बिमारियों से बचाव के लिए बायोसिक्योरिटी (जैविक सुरक्षा के नियमों ) का पालन करना बहुत ही जरुरी और महत्वपूर्ण है।
बायोसिक्योरिटी (जैविक सुरक्षा के नियम) :
ग्रोवेल एग्रोवेट प्राइवेट लिमिटेड के विशेषज्ञों का मानना है कि यदि योजनाबद्ध तरीके से ब्रायलर मुर्गीपालन किया जाए तो कम खर्च में अधिक आय की जा सकती है। बस तकनीकी चीजों पर ध्यान देने की जरूरत है। वजह, कभी-कभी लापरवाही के कारण इस व्यवसाय से जुड़े लोगों को भारी क्षति उठानी पड़ती है। इसलिए मुर्गीपालन में ब्रायलर फार्म का आकार और बायोसिक्योरिटी (जैविक सुरक्षा के नियम) पर विशेष ध्यान देना चाहिए। मुर्गियां तभी मरती हैं जब उनके रखरखाव में लापरवाही बरती जाए।
ब्रायलर मुर्गीपालन में हमें कुछ तकनीकी चीजों पर ध्यान देना चाहिए। जैविक सुरक्षा के नियम का भी पालन होना चाहिए। एक शेड में हमेशा एक ही ब्रीड के चूजे रखने चाहिए। आल-इन-आल आउट पद्धति का पालन करें। शेड तथा बर्तनों की साफ-सफाई पर ध्यान दें। बाहरी व्यक्तियों का प्रवेश वर्जित रखना चाहिए। कुत्ता, चूहा, गिलहरी, देशी मुर्गी आदि को शेड में न घुसने दें। मरे हुए चूजे, वैक्सीन के खाली बोतल को जलाकर नष्ट कर दें, समय-समय पर शेड के बाहर विराक्लीन ( Viraclean ) का छिड़काव व टीकाकरण नियमों का पालन करें। समय पर सही दवा का प्रयोग करें। पीने के पानी में एक्वाक्योर (Aquacure) का प्रयोग करें।
मुर्गा मंडी की गाड़ी को फार्म से दूर खड़ा करें। मुर्गी के शेड में प्रतिदिन 23 घंटे प्रकाश की आवश्यकता होती है। एक घंटे अंधेरा रखा जाता है। इसके पीछे मंशा यह कि बिजली कटने की स्थिति में मुर्गियां स्ट्रेस की शिकार न हों।
दूध उत्पादन व्यवसाय या डेयरी फार्मिंग छेटे व बड़े स्तर दोनों पर सबसे ज्यादा विस्तार में फैला हुआ व्यवसाय है। दूध उत्पादन व्यवसाय व्यवसायिक या छोटे स्तर पर दूध उत्पादन किसानों की कुल दूध उत्पादन में मदद करता है और उसकी आर्थिक वृद्धि को बढ़ाता है। इसमें कोई संदेह नहीं है कि, भारत में कई वर्षों से डेयरी व्यवसाय या दूध उत्पादन ने आर्थिक वृद्धि में सबसे महत्वपूर्ण भूमिका निभाई है। कुल दूध उत्पादन ने हमारे देश की अर्थव्यवस्था में बड़े स्तर पर भागीदारी की है और बहुत से गरीब किसानों को अपना व्यवसाय स्थापित करने में सहयोग किया है। यदि किसी के पास दूध उत्पादन का व्यवसाय स्थापित करने के लिए प्रारंभिक पूँजी है तो, इस (दूध उत्पादन) व्यवसाय को किसी भी क्षेत्रों में आसानी से स्थापित किया जा सकता है।
Pig is the only species of livestock from which major portion of the total investments made for establishing the farm can be earned back within 1½ – 2 years. Thus, the farmer is assured of getting over 60 per cent of profit margin from a marginal piggery unit. As a thumb rule, pigs have to put on more than 10 kg of body weight per month by consuming concentrate feed or agricultural byproducts or processed wastes from food industries. Though the white pigs have the western origin (temperate climate), they are better adapted to the Indian agro-climatic conditions. Nevertheless, the Large White Yorkshire breed is the widely accepted breed for pork (bacon, a cured meat from the back and side portions of the pig) production in the global scenario. Strategies have also been formulated to produce lean meat from synthetic strains of pigs through recent research approach, which would create better export opportunities. Hence, farmers without any doubt, can venture into farming this prolific species for their livelihood as well to contribute more to the GDP (Gross Domestic Product) to which contribution from livestock sector is, now-a-days, on the increase (from 4 to 8%).
The objective of commercial fish farming is to produce fish for sale and
earn profits. Therefore, production should be planned from the onset to
target identified markets. This means one should:
1. have the required product (size and form) available when the
market wants it,
2. be able to produce adequate volumes to sustain targeted markets,
3. produce at a competitive price and profit.
When making a production and business plan for table fish, one should
endeavor to answer the following questions beforehand.
1. Where is the market? – its location, what category of people are
likely to buy the fish I produce, etc
2. What does the market want? – type of fish, how much, what size,
how frequently, fresh or processed, etc.
3. What resources do I have? – number of pond(s), size of pond(s),

Few countries in the world have no sheep. They are found in tropical countries and in the arctic, in hot climates and in the cold, on the desert and in humid areas.
There are over 800 breeds of sheep in the world, in a variety of sizes, shapes, types and colours.
Sheep were domesticated long before the dawn of recorded history. Wool fibres have been found in remains of primitive villages of Switzerland that date back an estimated 20000 years. Egyptian sculpture dating 4000-5000 B.C. portrays the importance of this species to people. Much mention is
made in the Bible of flocks, shepherds, sacrificial lambs, and garments made of wool.
The Roman empire pried sheep, anointed them with special oils, and combed their fleece to produce fine quality fibres that were woven into fabric for the togas of the elite.
Perhaps the first ruminants domesticated by man along with goats, sheep are a very valuable and important asset to mankind.
Sheep is a important livestock species . They contribute greatly to the agrarian economy, especially in the arid/semi-arid and mountainous areas where crop and /or dairy farming are not economical. They play an important role in the livelihood of a large percentage of small and marginal
farmers and landless labourers engaged in sheep rearing. A number of rural-based industries use wool and sheep skins as raw material. Sheep manure is an important source of soil fertility, especially in southern states.
The aim of this booklet is to assist you in more effective use of pasture to achieve high sheep production. Essential for this are the ability to assess the amount of pasture in a paddock and knowledge of animal feeding needs.
This chapter discusses how to assess the amount of pasture in a paddock in relation to animal performance and seasonal pasture needs of sheep. The next chapter deals with setting up grazing rotations and feed budgeting.
Feed planning enables you to objectively match pasture supply and animal feed demands on your whole farm during the year. Some of you may feel daunted by this structured approach, but maximising production and achieving livestock target weights, including supply contracts, means more sophisticated pasture feeding.
Proper vaccination is an essential part of a good poultry management program and for the success of any poultry operation. Effective preventive procedures such as immunisation protect hundreds of millions of poultry worldwide from many contagious and deadly diseases and have resulted in improved flock health and production efficiency.
Immunization cannot be a substitute for poor bio-security and sanitation. Thus, vaccination programs may not totally protect birds that are under stress or in unhygienic conditions. The primary objective of immunizing any poultry flock is to reduce the level of clinical disease and to promote optimal performance. Certain vaccines may also have an impact on human health (i.e. Salmonella vaccines).
For breeders – we also want to accomplish some additional goals:
A. Protect the bird (as a pullet and hen) against specific diseases.
B. Protect the progeny of the hen against vertical transmission of disease.
C. Provide passive immunity to progeny.
In this book following points has been defined and described.

The term anatomy refers to the science that deals with the form and structure of animals. Physiology deals with the study of functions of the body or any of its parts. A thorough knowledge of the structure of an animal imparts a lot of information about the various functions it is capable of performing.
The course may be used as an introductory course to further studies; to assist you in recognising the normal, in order to determine the abnormal; to help you understand how to diagnose disease or determine if an animal has sustained an injury; to help understand the physical capabilities or limitations of particular species; to understand what happens in the nutrition and growth processes; and to assist you to get better performance from your animals.
Bio-Security plan is a set of practices designed to prevent the entry and spread of infectious diseases into and from a poultry farm.
Biosecurity requires the adoption of a set of attitudes and behaviours by people, to reduce risk in all activities involving poultry production and marketing.
Selection or formulation of appropriate diets for companion
and aviary birds is based on wild feeding ecology, digestive anatomy and physiology, and nutritional requirements of related species. Research indicates that requirements of some key nutrients for psittacines vary from those of poultry. Apart from vitamin E, there is no evidence to suggest that vitamin and trace mineral requirements for psittacines are greater than those recommended for poultry.54 While there are substantial differences between production species and companion
bird species, dietary requirements of poultry remain the
standard for estimating the needs of companion birds.
Individual nutrient classes will be discussed with particular
focus on recent research into the nutritional requirements of companion birds.
The decision to own and care for exotic birds is a decision which cannot be taken lightly. A lot of responsibility has to be accepted because a pet bird is not a low-maintenance pet. All pet birds require at least some specialized care.Very few “beginners” know the answers to the questions that arise concerning the management, breeding, rearing,disease prevention, and proper nutrition of birds. The “survivors” in aviculture have successful aviaries because their teacher has been experience, coupled with trial-anderror. Sometimes this teacher is expensive and can result in thousands of dollars of investment being lost. “Beginners” can increase their general knowledge in aviculture and
come up with answers to their questions by reading articles,
traveling to pet bird shows, attending lectures and talking
with people who have experience with pet birds.

Shrimp Farming
1. 1 Introduction:
monodon. About 1,90,000 ha brackish water area have been developed for shrimp culture in the country.
Since 1995 culture of P monodon is affected by White Spot Syndrome Virus (WSSV) and the development of
shrimp farming has been stagnant. Most of the South East Asian countries like Thailand, Vietnam,
Indonesia were also culturing P. monodon and since 2001-02 onwards most of them have shifted to
culture of exotic Whiteleg shrimp, Litopenaeus vannamei because of the availability of Specific Pathogen
Free (SPF) and Specific Pathogen Resistant (SPR) brood stock. In India, Pilot-scale introduction of L.
vannamei was initiated in 2003 and after a risk analysis study large-scale introduction has been permitted
in 2009.
2 Biology
L. vannamei is native of pacific coast of Mexico and Central and South America as far south as Peru. It is
mainly found on mud bottoms, down to a depth of 75 m. It is commonly known as white legged shrimp or
Mexican white shrimp. It is greyish-white in color. The maximum weight of the females in the wild is about
120 g. The males are smaller at 60-80g. It lives in the column and prefers clayey loam soil.
For L. vannamei the growth at 30°C is much higher than at 25°C. The optimal range of temperature for the
species is between 30 and 34°C. At 20°C growth virtually stops. It can tolerate salinity levels of 0 to 50 ppt.
Growth is uniform within 10-40 ppt. They can grow in freshwater also but the growth is slower below 10
ppt. pH range of 7 to 9 is tolerated with optimal growth at pH 8.0. Dissolved oxygen levels above 4.5 ppm
are required for optimal growth. Turbid water with flocculated particles of more than 0.5 micron resulted
in better growth than clean water mainly because of the presence of algae and bacteria. Ammonia -N and
Nitrite - N levels should be less than 0.1 ppm and 1 ppm respectively.
L. vannamei is an omnivorous scavenger and is less aggressive and less carnivorous than P. monodon. Food
Shrimp farming was synonymous with the mono culture of tiger shrimp, Penaeus
Shrimp Farming Guide
2. intake is more during evening and night. Retention time of food in the gut is 2.2 to 5 hours. Growth of L.
vannamei, under confined culture conditions is similar to P monodon till they attain 20g size. Beyond that
the growth rate was poor. The shrimps attained the size of 20g within a period of 100-120 days depending
on the stocking density.
3 Advantages of L. vannamei : Culture of L. vannamei, is being taken up in many countries because of the
following ccharacteristics: –
1. It grows as fast as P. monodon upto 20 g.
2. It is easier to culture in very high stocking densities of upto 150/sqm due to their less aggressive
nature.
3. It is tolerant to wide range of salinities of 0.5 to 45 ppt .
4. It is very tolerant to low temperatures of upto 15 degree centigrade
5. It requires comparatively low protein feed (20-35%).
6. It is an easy to breed species and hence domestication of the species is very successful with the
production of SPF stock. Commercial availability of SPF/SPR and High-health stock is an added
advantage.
7. Selective breeding work for the production of SPR brood stock is easier because of the short
generation period and easier captive breeding.
8. Higher survival rates in hatchery (50-60%).
9. Has a very good market in the US, as the most preferred species with higher meat yield (66-
68%).
4 Disadvantages of L. vannamei : The above advantages make L. vannamei a very important cultivable
species, however, the following disadvantages create some apprehension for its introduction in the
country:
1. L. vannamei is highly susceptible to and a carrier of TSV, WSSV, YHV, IHHNV and LOVV.
Though SPF stocks are available for these viruses, the performance of these in the virus
ladden environment is doubtful. WSSV is prevalent in the country and its infectivity and
pathogencity for L. vannamei is similar to that of P. monodon (Tapay et al. 1997)
2. L. vannamei is being cultured in very high densities under intensive management, which
might lead to environment problems like nutrient loading.
3. L. vannamei is highly susceptible to hypoxic conditions and hence there is a need for
continuos aeration during high density farming.
4. Handling, processing and transporting are more difficult in L. vannamei compared Penaeus
monodon.
5. There is high competition in the International market due to the world -wide production.
3. 5 Specific pathogen Free Stock:
L. vannamei is highly susceptible to a number of viral pathogens. White Spot Syndrome virus (WSSV),
Taura Syndrome Virus (TSV), Yellow Head Virus (YHV), Infectious Hypodermal Haematopoietic Necrosis
Virus (IHHNV), Lymphoid Organ Vacuolization Virus (LOW), Reo like Viruses (REO) are some of the
viruses reported in the species. In order to eliminate the presence the virus in the seed, Specific
Pathogen Free (SPF) stock has been developed by producing a number of generations in highly bio-
secure facility with continued surveillance of pathogen presence. Although SPF shrimp are, by definition,
free of all specifically listed pathogens, SPF shrimp may be infected with a known pathogen that is not
included on the SPF list of the shrimp supplier, or with an un-known pathogen that has not yet been
described. Offspring of SPF shrimp are not considered SPF unless they are produced and maintained at
an SPF facility. SPF status changes with the pathogen condition of the shrimp, as well as the type of
environment within which they are cultured (Le. I level of biosecurity). One of the main advantages of
culturing L. vannamei is commercially available as high health animals from Specific Pathogen Free (SPF)
stocks while P. monodon have very limited availability from SPF stocks.
6 Bio – Security requirements of shrimp farms:
Stocking of pathogen free post larvae alone will not guarantee a disease free culture since the
pathogens still enter the culture environment horizontally and infect shrimps during the culture. Viral
pathogens enter the culture pond through :
1. By persisting in the soil
2. Intake water
3. Aquatic vectors introduced through intake water, by crabs and other animals
4. Contaminated land animals and birds
5. Contaminated farm inputs & farm implements
Crabs are one of the major carriers of viral pathogens and providing crab fencing in shrimp farms is
considered as one of the important biosecurity measure. Carriers like crabs could also move from pond
to pond over land barriers. To prevent such movements fencing made of 0.5 m plastic sheet should be
put around culture pond.
Birds such as crow/ water crow pick up the dead and moribund shrimps affected with viral disease from
ponds and may drop unaffected ponds, there by transmitting the virus mechanically. This could be
avoided by using bird scares and bird fencing over the pond.
7 . Technical Parameters : Technical parameters of L vannamei culture include site selection, items of
pond development, pre and post stocking operations, stocking fertilisation, feeding harvesting and
post harvesting etc. are given in Annexure I
8 . Margin:

Technical Parameters Annexure I
1. Farm Design Requirements:
L.vannamei lives in the column and hence increasing the depth of the pond will help in increasing density.
Generally shrimp farms which were culturing P. monodon had a water depth of about 1 mt. But is
advisable to have a depth of 1.5 to 1.8 m water column for culturing L. vannamei.
Since mechanical aeration is one of the major requirements for L. vannamei culture due to higher
stocking density, constant circulation of water is expected in the pond. This will lead to the erosion of
the soil in the dyke and bottom. To avoid this compacting of the pond bottom and the dykes are
essential. In intensive culture ponds total lining of the pond HDPE sheets is done to avoid any type of
6. erosion. In high density culture systems, accumulation of sludge in the bottom is a major problem and
provision of central drainage or use of sludge pumps is essential. Positioning of paddle wheel/long arm
aerators should aide in bringing the sludge to the centre of the pond from where it can be removed.
Bio-security requirements like reservoir ponds, fencing, crab fencing bird fencing, and disinfection
facilities are incorporated in the design. To avoid disease in most cases zero-water exchange system of
farming is practiced with recirculation facilities. In such cases more than 40% of the water area in the
farm is allocated for reservoirs and waste sedimentation ponds.
2 Management of the farm
2. 1 Drying and Liming
The sludge left in the pond, may have the remains of the earlier viral disease outbreak , containing
high organic load, bacteria, viral particles and DNA as well as many other viral carriers. All these should
be removed to prevent the persistence of viral disease. This could be achieved by the application of
burnt lime (CaO) @100 ppm, followed by exposure of the pond bottom to sunlight until drying and
cracking, removal of the top soil and compacting the bottom soil
2. 2 Water Management :
White spot virus has been reported to survive as a free-living form in water up to seven days. Direct
use of creek or sea water carries the risk of introducing the virus into the system. Most of the aquatic
crustaceans including the planktonic forms are reported to be carriers of WSSV virus. A number of
other aquatic organisms could be mechanical carriers because of their filter-feeding habit. There is a
need to eliminate these from water before use in culture ponds. Use of filter nets 60 micron mesh/sq
cm in the delivery pipes/ inlet sluice should be strictly followed. Water should be taken in reservoir
ponds and treated with calcium hypochlorite @ 30 ppm and aged up to seven days, to eliminate the
viral pathogens.
Farmers should ensure that only treated water be used in the culture ponds for compensating the
evaporation losses. Regular water exchange is not advised to avoid cross contamination pathogens
from the source water.
2.3. Fertilization and addition of carbon source
Culture of L. vannamei can be done under two systems - with plankton as natural feed or with
bacterial floc. The fertilization schedule with urea and superphosphate is followed for plankton
development while provision of carbon source in the form of molasses and dolomite is used for
development of bacterial floc. The volume of bio-floc was controlled at 15 ml/ litre.
2.4 . Stocking:
SPF shrimp seed from a reputed approved hatchery may be used for stocking. PL8- PL9 is normally
selected after ensuring the pathogen free status of the seed. The seed acclimatization is a very
important requirement before stocking. Temperature, salinity and pH of the transportation water
7. Vannamei 2015
should gradually brought to the level of pond water by gradual mixing of both over a period of 6-12
hours depending on the difference. Stocking densities of 40 to 60 no/sq m is preferred. Higher stock
densities above 60 no./sq m is not permitted.
2. 5 Feed Management:
Protein requirement varies between 25 to 40% depending on the density. Marine source protein was
more effective than plant source. Lipid requirement is around 6-8% with 2% marine unsaturated fatty
acids and 0.25 to 0.4% of cholesterol. Feeding rate is between 6.6 to 16% for 1 gm of shrimp which will
be reduced to 2% for 15 gm shrimp. Optimal feeding frequency is between 2 and 6 in a day with
maximum percentage of feed distributed in the evening and night rations. Check trays are used to
monitor the feed consumption and the feeding ration is adjusted accordingly. FCR levels of 1.1 to 1.4 are
expected.
2.6 Maintenance of Water Quality:
Regular monitoring of water quality is very essential. Water quality parameters like temperature,
salinity, pH and alkalinity are monitored on daily basis. DO levels are recorded at least 2 times a day.
Other parameters like Ammonia, Nitrite, Calcium, Magnesium are monitored on weekly basis. DO levels
should be maintained above 4 ppm although and operation of paddle wheel /long arm aerators should
done to maintain the level. The number of aerators required is about 1 HP per every 300 kg of mass. The
location of the aerators should be adjusted in such way the sedimentation occurs at centre of the pond,
which will help in its easy removal.
Removal of sludge from the pond bottom during culture is essential in case of high density. Aerators are
positioned in such a way that the sludge is accumulated in the center of the pond and from there it
could be removed through central drainage or using sludge pumps. To aid in the process, sludge settled
in other places should be disturbed regularly. This is achieved through dragging of chains at the bottom
at regular intervals on all sides of the pond
2.7. Health Management:
Weekly monitoring of shrimps for their growth and well being is essential. L. vannamei normally grows
at the rate of 0.2gm /day after the first 30 days. Weekly growth rate will range between 1.5 to 2.0 gm
depending on the stocking density. At 60
nos./m2
the shrimps attain 20g size within
100 -120 days.
3.0 . Harvest and Post Harvest
8. L. vannamei is a column living shrimp and hence maximum stock can be harvested by either by cast nets
or drag netting and this will help in harvesting without much overcrowding or stress. Final harvesting by
draining the water should be done within 6 hours. Compared to P. monodon, L. vannamei discolours
faster if there is any delay in icing the harvested stock. Hence the stock should be 'ice killed'
immediately on harvest and stored in ice.
4. Cost of production:
The cost of production of L. vannamei in Indian conditions considering the industrial rate for electricity
might work out to Rs. 150 -160 for production levels of 8 to 10 tons per ha. The
average size at harvest ranges from 20 to 25 g and the sale price is more or less same
for both P. monodon and L. vannamei of similar size at Rs. 200 to 220. The profit margin is very high and
even if only 50% of the area will be utilized for grow-out, it is beneficial than P. monodon culture.
5. Conclusion:
L.vannamei is very suitable species for semi-intensive culture with the availability of pathogen free seed.
The major issues to be considered are bio-security and maintenance of water quality through constant
monitoring. It also requires higher technical knowledge to achieve higher production in sustainable
manner. Strict adherence to the guidelines of Coastal Aquaculture Authority is a must to ensure
environment protection.
