Fish culture involves raising fish in captivity and managing their environment. It has several purposes like enhancing food supply and income. There are different methods of fish culture based on factors like the level of investment, water conditions, and fish species. Common methods include pond, pen, cage, and tank systems. Fish culture provides food and economic benefits while supporting sustainable use of resources.
What is the stocking density of fish in semi intensive cultureihn FreeStyle Corp.
Stocking Density: Stocking density also known as per-unit stocking amount or stocking rate, refers to the quantity of fry or fingerlings per unit of water area.
Poly Culture: The concept of poly culture of fish is based on the concept of total utilization of different trophic and spatial niches of a pond in order to obtain maximum fish production per unit area. Different compatible species of fish of different trophic and spatial niches are raised together in the same pond to utilize all sorts of natural food available in the pond.
Semi Intensive Culture: Semi-intensive culture systems depend largely on natural food which is increased over baseline levels by fertilization and/or use of supplementary feed to complement natural food.
Fish is a valuable source of high quality protein and, in the case of oily fish, fats of considerable nutritional importance. In many countries, large-scale commercial fish processing (mainly freezing for export and canning) takes place in parallel with traditional processing. The methods used by smaller enterprises remain based on traditional techniques of drying, salting, smoking and fermentation.
There are more than 27 000 species of salt and freshwater fish; many more crustaceans, bivalves, and cephalopods can also be eaten. Fish and shellfish are the only foods that, globally, are still obtained in significant quantities from the wild. But many species are on the verge of commercial extinction and aquaculture is increasing worldwide. For instance, more than a third of the salmon eaten worldwide is farmed. Like meat, fish is also processed, for instance by drying, salting, and smoking.

The traditional fishery byproducts are fishmeal, fish body and liver oils, fish maw, isinglass etc. Fish protein concentrate, fish albumin, glue, gelatin, pearl essence, peptones, amino acids, protamines, fish skin leather etc. are some other byproducts generally processed out of fish and fish waste.
Fish can be cultured in one of four culture systems: ponds, raceways, recirculating systems or cages. A cage or net pen is a system that confines the fish or shellfish in a mesh enclosure.
Fishing is the art of catching fish and other aquatic animals. Many years ago man started using various type of gear used for hunting the terrestrial animals and for fishing also. It is very difficult to say which started first, but some time it is opined that fishing is younger. Reason behind it is easy to catch animals in the land than in the water. In olden days fishing was not having much importance as there was no demand for fish. Earlier fishing was restricted to a particular community but it is not so now. In order to meet the increased demand, fishing is now carried out industrially. Fishing technology not only concerns fishing gear, fishing methods and vessels but also concern Biological and Environmental factors

Fish farming is the principal form of aquaculture, while other methods may fall under mariculture. Fish farming involves raising fish commercially in tanks or enclosures, usually for food. A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery. Worldwide, the most important fish species used in fish farming are carp, salmon, tilapia and catfish.
There is an increasing demand for fish and fish protein, which has resulted in widespread overfishing in wild fisheries. Fish farming offers fish marketers another source. However, farming carnivorous fish, such as salmon, does not always reduce pressure on wild fisheries, since carnivorous farmed fish are usually fed fishmeal and fish oil extracted from wild forage fish. The global returns for fish farming recorded by the FAO in 2008 totalled 33.8 million tonnes worth about $US 60 billion.
Specific types of fish farms[edit source | editbeta]
Within intensive and extensive aquaculture methods, there are numerous specific types of fish farms; each has benefits and applications unique to its design.
Cage system[edit source | editbeta]
Giant gourami is often raised in cages in central Thailand
Fish cages are placed in lakes, bayous, ponds, rivers or oceans to contain and protect fish until they can be harvested. The method is also called "off-shore cultivation[7] " when the cages are placed in the sea. They can be constructed of a wide variety of components. Fish are stocked in cages, artificially fed, and harvested when they reach market size. A few advantages of fish farming with cages are that many types of waters can be used (rivers, lakes, filled quarries, etc.), many types of fish can be raised, and fish farming can co-exist with sport fishing and other water uses. Cage farming of fishes in open seas is also gaining popularity. Concerns of disease, poaching, poor water quality, etc., lead some to believe that in general, pond systems are easier to manage and simpler to start. Also, past occurrences of cage-failures leading to escapes, have raised concern regarding the culture of non-native fish species in open-water cages. Even though the cage-industry has made numerous technological advances in cage construction in recent years, the concern for escapes remains valid.
Main article: Copper alloys in aquaculture
Recently, copper alloys have become important netting materials in aquaculture. Copper alloys are antimicrobial, that is, they destroy bacteria, viruses, fungi, algae, and other microbes. In the marine environment, the antimicrobial/algaecidal properties of copper alloys prevent biofouling, which can briefly be described as the undesirable accumulation, adhesion, and growth of microorganisms, plants, algae, tube worms, barnacles, mollusks, and other organisms.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

1. CHAPTER 7:
FISH CULTURE
LESSON 1: ASPECTS, CLASSIFICATIONS, AND METHODS OF FISH CULTURE
PRESENTATION BY: ANDRELYN D. DITAN & ANGEL D. SAMPAGA
2. WHAT IS FISH CULTURE?
➢Fish culture or also known as “fish farming” is the process of raising desirable
species of fish in captivity and managing them and their environment to improve
growth and reproduction.
➢Is a program where it is introduced to enhance awareness and adopt some of the
technology and its adoption as an additional source of food and income.
3. PHASES OR ASPECTS OF FISH CULTURE
1. FISH CULTIVATION
• The rearing of fish under
Controlled and semi-controlled
Conditions.
4. FISH CULTURE AND REARING TYPES
• 1. COMPOSITE FISH CULTURE
- Also known as polyculture, is the maximum exploitation of aquatic resources through the
introduction of selected varieties of compatible fish to achieve high productivity.
• 2. CAGE CULTURE
- In cage culture, the fishes are reared in a cage made of nylon and wooden frame and
sometimes in a cage made of bamboo mesh. These cages are kept in flowing wastewater
canals.
5. • 3. INTEGRATED FISH CULTURE
- Culturing of fish in association with agriculture or ducks or chicks or pigs or prawns is called
integrated fish culture. Fish wastes fertilize the crop fields while wastes from crops and poultry
integrated-fish-culture chicks are used as feed by fish.
• TYPES OF INTEGRATED FISH CULTURE:
❖A. FISH-PRAWN CULTURE - Prawns are cultured in ponds which are meant for carp culture in
this method. The excreta of carp fishes constitute food for prawns.
❖B. FISH-POULTRY CULTURE - In this type of poultry farm is constructed over a platform built of
bamboo sticks above the water level of the pond. This facilitates direct fertilization of the pond by
droppings of chick which are rich in nitrogen and phosphorus.
6. ❖C. RICE - FISH CULTURE - Fish are cultured in rice fields in this method. Fishes that
can live in a depth of 15cm are selected for this culture. The rice variety selected for this
purpose should also develop a strong root system.
❖D. FISH CULTURE IN POKKALI FIELDS - This practice is followed in Kerala.
Prawn, fish, and rice are cultured on a rotational basis in the pokkali rice fields which are
influenced by the tides of Vembanad backwaters. Rice cultivation is taken up from June to
September. Fish and prawns are cultured up to May.
❖E. COCONUT OR BANANA - FISH CULTURE
- In banana or coconut fields, the ditches or canals in between the rows of plants can be utilized
for fish culture in this method. These canals are always filled with water and rich in insect
populations.
7. ❖4. LACUSTRINE FISHERIES
- The culture of fish intake constitutes lacustrine fisheries. Natural lakes of 0.72 million hectares and
manmade lakes of 65 million hectares are available for fish culture in India.
❖5. SEWAGE FISHERIES
- In many countries fish are introduced and cultured on a commercial basis in sewage canals and
ponds. The sewage is used as fertilizer in culture ponds and as feed for fish.
8. 2. FISH PROPAGATION
• The process of increasing fish life either by natural or artificial means of reproduction
The following are the different methods 2.
Of propagation:
1. ARTIFICIAL PROPAGATION
3.
9. 3. FISH CONSERVATION
• The scientific means of conserving fish and other fishery aquatic products/resources. It helps to keep the
sport of fishing alive. It also helps to maintain the balance of certain ecosystems.
10. CLASSIFICATION OF FISH CULTURE
1. ACCORDING TO EXTENT OF FINANCIAL INVESTMENT
• A. INTENSIVE - Utilizes limited area with very high investment
• B. EXTENSIVE - Utilizes a wide area with minimal capital and very low production
• C. SEMI-INTENSIVE - Employ some or the majority of the modern techniques of production
11. 2. ACCORDING TO PURPOSE
• A. For Commerce Or For Business
• B. For Recreation Or For Enjoyment
• C. For Educational And Cultural Or Scientific Pursuit
• D. For Food Production
3. ACCORDING TO DESIGN
• A. Natural Pond
• B. Artificial Pond
4. ACCORDING TO THE STATE OF WATER
• A. Still Water
• B. Running Water
12. 5. ACCORDING TO SALINITY
• A. Freshwater
• B. Brackish-water
• C. Marine Or Saltwater
6. ACCORDING TO TEMPERATURE
• A. Warm Water Or Hot Water
• B. Cold Water
7. ACCORDING TO SPECIES RAISED
• A. Freshwater Species
• B. Brackish-water Species
• C. Marine Or Saltwater Species
13. METHODS OF FISH CULTIVATION IN FISH CULTURE
• Based on the structures used in Fish Cultivation, they can be
classified into five(5) methods:
1. FISH POND METHOD
2. FISH PEN METHOD
3. FISH CAGE METHOD
4. FISH TANKS METHOD
5. OPEN-WATER METHOD
14. FISH POND METHOD
• Fish pond is the most widely used. Fry or fingerlings of one or more species
are stocked and reared in ponds up to harvest time. Natural food is grown in
ponds. The supplementary feed is added. The method of harvesting is
draining the pond. Retrieval of fish in this way is complete. Another method
of harvesting is freshening in the case of bangus. Having positive
rheotaxism, the fish are induced to go against the water current by the gate
and concentrated into a catching pond where they are scooped.
15. FISH PEN METHOD
• The fish pen method of fish cultivation is undertaken in net enclosures in
shallow protected areas of inland waters. Bamboo and wood materials ate
used as posts and braces. Its lower end is embedded in the mud to prevent the
escape of stock by excavating under, while the upper end is extended two
meters or more beyond the water level to escape of fish by jumping out.
Harvest of fish is done by seining or shocking them with electricity.
16. FISH CAGE METHOD
• The fish cage method of fish cultivation is also undertaken in inland bodies of
water, both in flowing and still water ones. The structure used is also made of
nets. PVC pipes as framing materials are preferred to that wood or bamboo. A
cage is much smaller than a fish pen. The cage is closed on all sides and
installed in suspension. The fish cage is stationary and movable. Floating and
fixed cages have an open tops. The growth rate of fish is dependent on the
kind and amount of food given and the suitability of the environment.
Harvesting stock is relatively easy and complete. The fish is either scooped or
the cage is merely brought out of the water to empty the fish.
17. FISH TANK METHOD
• The fish tank method of fish cultivation is practiced primarily by fish
hobbyists and in pet shops. The method employs varying sizes and shapes of
fish culture structures. These include glass bowls or aquaria and wooden or
concrete tanks. This method of cultivation is done outdoors and indoors. The
method involves the rearing or breeding of ornamental or fancy, colorful
species of fish.
18. OPEN-WATER METHOD
• The fifth method of fish cultivation is the open-water method.
It is done in bays, coastal lagoons, canals, and similar
environments.
19. WHY IS FISH CULTURE IMPORTANT?
• Through aquaculture, our oceans, seas, and inland freshwaters hold huge potential to provide us
with increased amounts of healthy and nutritious food. This is needed to feed an ever-growing
human population so aquaculture helps us with our food security.
• Increase income and also improve livelihoods, promote economic growth, and protect our
environment and natural resources.
• Make an important contribution to sustainable incomes and employment opportunities.
• And many more…..
