Raising Fish in Fish Farms

METHODS: There are various stages and methods for raising fish in fish farms. The lifespan of a fish usually starts with a hatchery, and the life cycle of a hatchery begins with the hatching and breeding of eggs, and finally it is released as a fry or continues to live in a fish farm. Concern about a large number of hatchery cultures is that they compete for local fish and food. Seafood watch at the Monterey Bay Aquarium said, "People are concerned that breeding of fish in hatcheries is related to the breeding of wild populations and may pose a threat."

Fish farming is a kind of aquaculture, fish are kept in the fence to sell as food. It is the fastest growing area of ​​food production for animals. Today, about half of the world's fish are raised in these artificial environments. Common breeding species include salmon, tuna, mackerel, mackerel, and flounder. These "aqua farms" can be used for mesh cages immersed in natural waters and on concrete fences on land. According to the UN Food and Agriculture Organization, about 32% of the world's fish stocks are overfished, depleted or recovered, and urgent reconstruction is necessary. Fish farming is welcomed as a solution to the overfishing problem. However, these farms are far from benign and can cause serious damage to ecosystems by introducing diseases, pollutants, and invasive species. The damage caused by the fish farm varies depending on the type of fish, farming method, production scale, farm location.

While other methods may be marine aquaculture, fish farming is the main form of aquaculture. It usually involves commercial farming with tanks or pens for food. For recreational fishing, or to compensate for the natural population of species, facilities that release the fry in the wild are often called fish farms. Fish cultivated in fish farms include salmon, trout, tilapia, squid, trout and so on. Fishery management uses fisheries science to find ways to protect fishery resources for sustainable development. Modern fishery management is often referred to as a combination of government system (hopefully appropriate) management rules based on established objectives and management tools for executing rules executed by supervisory control and monitoring systems .
