Freshwater aquaculture relies on fish seed from hatcheries and wild sources. Hatchery management involves maintaining broodstock and producing quality seed through induced breeding and quarantine practices. The broodstock management process includes pre-spawning procedures like selection, maintenance and spawning as well as post-spawning activities such as handling, rearing and health management. Quarantine and genetic improvement programs help select broodstock with desirable traits and disease resistance. Ensuring quality seed through certification standards improves survival and growth performance. National committees in different countries formulate policies and legislation around fish seed certification and quarantine.

Broodstock And Hatchery Management Of Penaeus Monodon
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.

Asian sea bass culture
Asian sea bass, also known as giant perch or Bhetki, is a profitable species for aquaculture in Southeast Asia. It can be cultured in both freshwater and saltwater. Hatcheries in Thailand produce sea bass fry that are also exported to other countries. Major challenges for sea bass culture are cannibalism among young fish and dependence on fishmeal. The life cycle involves nursery rearing of fry from 2-5 grams to 5-10 centimeters, then grow out in ponds or cages to a market size of 300-400 grams in 3-4 months or 700-1200 grams in 8-12 months. Sea bass is commonly cultured with tilapia in polyculture systems.
Spf and spr
1. SPF animals are free from specific pathogens but may still be susceptible to infection. SPR animals have been selectively bred for resistance to particular pathogens through challenge testing.
2. Non-SPF broodstock can introduce novel diseases and pass pathogens to offspring without strict biosecurity. They may not have been selectively bred.
3. True SPF status requires rigorous screening and production in biosecure facilities; outside these facilities animals may still be disease-free but are no longer considered SPF.
ASIAN SEABASS CULTURE
Asian sea bass (Lates calcarifer) is an important species for aquaculture in Southeast Asia. It can be cultured in both freshwater and saltwater. Major issues in sea bass culture include cannibalism in young stages, dependence on high protein feed sources, and unpredictable wild fry availability. Sea bass nursery rearing is typically done in earthen ponds, concrete tanks, or net cages with fry stocked at high densities. Grow-out is usually done in ponds or cages at lower stocking densities, feeding on trash fish. Sea bass polyculture with tilapia is also common, with sea bass reaching market size of 600g within 4-5 months.
Cage culture
Cage culture involves confining fish or shellfish within mesh enclosures in existing water bodies like ponds, rivers, and oceans. Some key advantages are the flexibility to use different water resources with minimal initial investment. However, there are also disadvantages like the need for complete diets, high risk of disease transmission due to crowding, potential for localized water quality issues, and limitations to production yields. Cage aquaculture has rapidly expanded in recent decades and continues to adapt to growing global demand through clustering cages and developing more intensive cage farming systems.

Breeding techniques include inbreeding to increase homozygosity, outbreeding between unrelated animals, and artificial insemination. Plant breeding aims to develop varieties with higher yields, nutrition, stress tolerance and disease/pest resistance through techniques like hybridization, selection, and mutation breeding. Semi-dwarf rice and wheat varieties greatly increased grain production in India.

Economics of fish hatcheries and grow out
This document discusses the economics of fish hatcheries and grow-out facilities. Key factors to consider when constructing a hatchery include the layout, type of fish to breed, and water supply and quality. Hatcheries produce juvenile fish to support aquaculture by transferring them to grow-out systems on farms. Grow-out facilities allow hatchery fish to reach harvest size. Hatcheries can help ensure consistent fish supply, support genetic improvement, and provide healthy, uniform fish seeds for farming when sited properly and run effectively.

Identification of fish seed
This document provides information on fish and shrimp seed identification. It defines the different life stages of fish from hatchling to fingerling and describes their characteristics. Hatchling emerges from fertilized eggs with a yolk sac. As the yolk is absorbed, it becomes a spawn with a formed mouth. At 1-2 cm, it is a fry that feeds on zooplankton. A fingerling is 10-15 cm in size, suitable for stocking. Seed quality is determined by factors like uniform size and age, disease resistance, and genetic potential. Good hatchery and nursery management through practices like disease control are important to achieve quality seed.
Gene bank.pptx
Gene Banks are a type of bio-repository which preserve genetic material.
A collection of seed plants, tissue cultures etc. from potentially useful species , especially species containing genes of significance to the breeding of crops.
Fish genetic material in a 'gene bank' is preserved at -196° Celsius in Liquid Nitrogen as mature seed (dry) or tissue (meristems).
Gene banks exist to conserve the genetic diversity of wild and domesticated organisms that humans depend on for food, fibre, medicine & energy.
Importance of interspecific hybridisation.pptx
Interspecific hybridization in aquaculture can increase growth rate, productivity, transfer desirable traits, and improve environmental tolerances. It has led to substantial increases in aquaculture production for certain species, such as hybrid catfish in Thailand and hybrid tilapia in Israel. However, the success of interspecific hybridization depends on genetic and non-genetic factors, and can vary between species. It also requires proper broodstock management to monitor hybrid viability and fertility. Unintentional hybridization may negatively impact hybrid progeny traits and genetic integrity if escapes occur.

Js fish seed certification
- 1. FISH SEED CERTIFICATION AND QUARANTINE PROCEDURES MISS. JAYASHRI S. SHELKE FGB-03/19 Central Agricultural University, Tripura
- 2. • Freshwater aquaculture contribution to the total aquaculture more than 50 percent production. • Source of seeds -wild resources, hatcheries , import from other countries. • Induced breeding-main method of seed production. • Wild collected seeds are mainly used for maintaining the quality of broodstocks.
- 3. HATCHERY MANAGEMENT • Hatchery management: 1) Single species or 2) Multi-species. • Broodstocks are kept separately by species or together as mixed species. • Broodstock results in better breeding responses and increased fecundity, fertilization, hatching and larval survival rates and more viable fish seed.
- 4. The broodstock management process can be divided into (a) Pre-spawning process . (b) Post-spawning process. Pre-spawning process: Includes procedures for Broodstock Selection and Procurement,Maintenance,Maturation, Acclimatization, Spawning and Hatching.
- 5. Post-spawning process Facility maintenance, Water quality management, Broodstock handling; Washing, Selection, Holding and transfer/transport of spawn, Rearing of spawn, Maintenance, Health management, Assessment of condition, Selection and Risk assessment for stocking, Documentation and Record keeping.
- 6. QUARANTINE Quarantine -a closed holding area where brood fish are kept in individual tanks until the results of screening for known diseases or disorders are known. Kept some distance from the hatchery. Improvement of domesticated broodstock -genetic improvement programme (GIFT)
- 7. • GIFT results in selection for desirable traits, Stocks with better traits (colour, growth) or are free from, or suspected to be resistant or tolerant to, specific conditions or pathogens.
- 8. FISH SEED QUALITY ASSURANCE • Poor quality seed-major constraint. • As per “Aquatic Seed Management” definition of the Ministry of Agriculture, fish breeders should obtain the broodstock from one of the centers established under the National Aquatic Bred and Wild Seed System (NABWSS), which includes genetic breeding center (GBC), wild variety collection center (WVCC), wild/bred variety amplifier (WBVA), exotic species centers (ESC) and seed quality inspection centers (SQIC).
- 9. Quality criteria includes: Age and uniformity of size in terms of weight and Length (Indonesia, Thailand), Growth performance, survival and percentage of Deformities (Vietnam) Body shape and behaviour (Sri Lanka.)
- 10. Causative Agents for Severe Mortalities: Ichthyopthirius sp. (ich disease), Trichodina spp., Ichthyobodo spp., Lernaea spp., Myxobolus spp.,Dactylogyrus spp.-affect the gills and cause heavy mortalities in Catla catla.
- 11. • Using the same brooders more than once in a breeding season causes deterioration of larval quality, mortality and larval deformity. • Preserving the genetic quality of broodstock assures high quality seed.
- 12. FISH SEED CERTIFICATION Country Committee Role Bangladesh National Committee Preparing a policy for seed certification India NBFGR,Lucknow, Uttar Pradesh Recognized nodal agency for formulating legislation on aquatic animal health certification and quarantine China National Certification Committee Certification of genetically improved varieties on Aquatic Wild and Bred Varieties (NCCA-WBV) Philippines BFAR Certifies and distributes improved tilapia strains
