Objectives of Fish Farming: Benefits and Types of Farming Methods

Fish farming, commonly referred to as aquaculture or fish farming, is the activity of raising fish in enclosures or tanks for commercial gain. Fish farming’s primary goal is to supply the market’s rising demand for fish, especially in light of global population growth and dwindling wild fish populations. Other equally significant goals of fish farming include easing pressure on wild fish stocks, generating employment opportunities, and ensuring food security. Factors Affecting the Culture of Fish

For fish to develop and reproduce, the environment must be favorable for farming. Some of the important elements that have an impact on fish culture are water quality, temperature, pH, dissolved oxygen, and salinity. Farmers must make sure their fish are kept in the best circumstances possible because different fish species have distinct needs in these areas. The success of fish farming is also influenced by other elements like the type of feed, disease control, and genetics. Different Forms of Fish Farming Freshwater fish farming, marine fish farming, and brackish water fish farming are the three subsets of fish farming. Fish are raised in freshwater ponds, tanks, or cages in freshwater fish farming, which is the most popular method of fish farming. On the other hand, marine fish farming is the process of raising fish in saltwater habitats like oceans, seas, or bays. Fish are raised in estuaries or brackish water as part of brackish water fish farming, which combines freshwater and marine fish farming. Farming Techniques

Fish farming uses a variety of farming techniques, such as extensive, semi-intensive, and intensive techniques. Fish are raised in natural water sources like lakes, rivers, or ponds as part of extensive fish farming. Fish farmers that practice semi-intensive fish farming utilize artificial ponds or tanks and add feed and fertilizer to help the fish develop. High-density culture, also known as intensive fish farming, makes use of recirculating aquaculture systems or tanks where farmers supply all necessary inputs, including feed, oxygen, and water filtration, to enhance fish development.

The price of catfish, one of the most popular fish species in Nigeria, varies by geography and market demand. Depending on the size and location, 1 kg of catfish in Nigeria can cost anywhere from N800 to N1,500. However, because to high demand during the peak season, catfish prices may rise, while low demand during the off-peak season may cause prices to fall.

In summary, there are several advantages to fish farming, including a source of income, food security, and lessening the strain on wild fish stocks. The success of fish farming is influenced by variables such water quality, temperature, diet, and disease management. Fish can be raised using a variety of farming techniques, including extensive, semi-intensive, and intensive approaches. Finally, the cost of catfish varies throughout Nigeria depending on the market’s need and the area.
