From the nutritional point of view, aquatic organisms are good. Because it is the biggest source of protein. Two methods of marine fish farming are mainly used. Which includes catching fish from marine or natural water sources and creating artificial water sources to feed the fish.
The water source for fish farming
Water sources of the fish are seawater and freshwater. Sweet water is found in rivers, lakes, and ponds. Therefore fishing and fish culture can be done in the ocean and freshwater ecosystems. Growth and production in the fish industry are more in freshwater than in saltwater.

What is Fish Farming and How to Start
Fisheries are a highly profitable business, which you can be started the favorable conditions available. Very few people know about this subject,
Whereas fish farming is important in the economy. Pond and sea can do good business by starting fish farming and catching at both these places.
Fish farming is a good source of human nutrition
Fishery – Due to fish being a good source of human nutrition, today it has been established as a profitable business. Fish is mainly used as a food item.
But vitamin-rich oils, proteins, fats, fins, skin, scales, etc. are by-products obtained from fish. Fish farming is a combination of both agriculture and animal husbandry because fish farming is a type of animal husbandry and the production of food in the reservoir for fish is an agricultural activity.
Habitat of fish farming
Fish farming is done in natural water resources like the sea, ponds, lakes, and rivers, but fishes are also reared and produced in artificial reservoirs. The place with clayey soil is considered good from the point of view of reservoir construction.
Species of fish Farming
The production of fish is more in freshwater than in saltwater. For freshwater fish farming, indigenous fishes like Rohu, Mrugala, and Katla, etc. are followed, along with foreign fishes like Commoncorp, Silvercorp, etc. are also reared.
Food for fish farming
The food of fish in natural water bodies are microscopic aquatic plants and micro-organisms. Rice husks, grain pieces, wheat flakes, almond cake, and soybeans are given as food in artificial reservoirs.
Fish production for fish farming
The seeds of fish are collected from the breeding sites of rivers with the help of nets. Eggs are produced from seeds. The small fish that came out of the eggs are called cumin. Cumin turns into fingers after some time. The fingers are transported to the reservoirs built for fish farming. To destroy the infectious bacteria of the fingers, they are treated with bactericidal substances such as copper sulfate, formalin, potassium permanganate, or salt.
When the fish become big enough, they are collected with the help of a net or by electric current in the reservoir.
Preservation of fish
To protect the fish from rotting, they are preserved by pressing them in ice.

Fish is a good source of protein and today, which is in great demand not only in India but all over the world and is increasing continuously. This business is growing very fast and is creating new business avenues for the people.
India has the second rank in fish farming
India ranks second in fish production. Therefore this business can give you a lot of profit. There are many benefits of this business.
Marine fish production in India
The marine fish processing area of India is up to 7500 km of sea level and in addition to the depth of the sea. The most common marine fish are pomfret, mackerel, tuna, sardines, and bombed.
Different types of nets are used for saltwater fishing, along with special types of fishing boats.
Some of the most profitable fish species are also cultivated in this water. Prominent among these are mullet, bhetki, and pearl spot; shellfish such as shrimp, mussel, and anter are cultivated to obtain pearls.
In the event of a shortage of fish stocks in the future, the fish can be replenished by enrichment. This system is called marine culture.
Indoor fish farming in India
The sources of freshwater are drains, ponds, puddles, and rivers. Brackish water resources where seawater and freshwater mix. Such as the river mouth (Acheuri) and the lagoon are also important to fish storage areas.
When the collection of fish is done on terrestrial sources the production is not high. Most of the fish production from these sources is done through water culture.

Fish farming is sometimes done along with the paddy crop. More fish culture can be done with a mixed fish culture system. In this process, 3 indigenous and imported types of fish are used.
In such a system, 5 or 6 species of fish were used in the same pond. In these such fish are selected.
In which there is no competition for food and their diet is different. As a result, the food available in each part of the pond gets used up. As the Catla fish gets food from the surface of the water,
Rohu fish gets its food from the central area of the pond. Mrugala and Common carp take food from the bottom of the pond. Grass carp eats weeds.
In this way, all the fish, while living together, take their own food without competition. This also increases fish production in the pond.
Pangasius fish farming
It is also called pangas fish. It is third place in terms of numbers among all the fish found in the world. Its growth is most rapid.
In 7-8 months, the weight of the baby of this fish goes up to one and a half to two kilos. It is followed mostly in the state of Andhra Pradesh in India.
The biggest feature of this pangas fish is that it is able to keep itself alive even on the low amount of dissolved oxygen in the water. The climate of Jharkhand is considered to be the best for this breed of fish.
Even in small ponds, it is possible to produce pangas well in a period of 5-6 months. They can also be cultivated by keeping them in small aquariums. It is as shiny as a shark fish.
Major breed of fish in India
For freshwater fish farming, only fish of a particular species (breed) is selected. Among these, mainly native fishes like Catla, Rohu (Labeo), Mrugala, etc. are prominent. Apart from this, exotic fish like silver carp, common carp, Grass carp are included.
Fish food for fish farming in India
The fish in the reservoir requires two types of food.
Natural food – These are micro-plants and micro-animals, their production continues to be regular, for this, artificial manure and fertilizers are used. For this, organic manure and chicken beets are added. Small amounts of lime are also added to reduce the acidity of the water.
Along with natural food, artificial feeding has its own importance for the proper and rapid growth of the fish. Among them, rice bran, grain pieces, broken rice, soybean, yeast, almond cake, etc. are prominent.
Cumin accumulation– Small fish are called cumin seeds. The length of cumin is 1 to 1.5 inches. Only a certain amount of cumin should be put in the pond. Before putting them in the pond, they should be kept in a 3% salt or potassium permanganate solution for some time so that these parasites can be free.
Cumin becomes fingers after three to four months. Its length is three to four inches. This stage grows into an adult fish in 6 to 12 months.
Precautions for fish farming (6 safety practices while fishing)
The following precautions should be taken by the fishermen while rearing fish.
- Cumin should be stored in the reservoir only in the morning.
- Cleaning of the pond should be done regularly. Due to this, the useless and harmful vegetation should be removed from time to time and separated.
- The fish that change at certain intervals should be examined so that the diseases caused by them can be detected and their regular treatment should also be done.
- The diseased fish should be taken out and destroyed.
- Fish should not be removed when it is cloudy or when there is lightning.
- The food given to the fish should be interesting and nutritious for them.
