The U.S. fish farming industry is well established and diverse, according to the United Nations Food and Agriculture Organization. The first fish hatchery in the United States was in Madison, Wisconsin in 1887, but there are several thousand today. Although some fish farms in the United States breed recreational or ornamental fish, the majority are fish that are made for human consumption. Fish can be raised in ponds, circulation tanks, running tracks, cages, or net pens. However, the types of successful fish farms depend heavily on market demand and water quality, flow, oxygen and temperature.
The most popular species in US fish farming. By the time they reach about 1½ pounds, catfish, usually sewer catfish, have an efficient rate of converting pellet feed into pounds of fish. Catfish is a warm water species that actively feeds and grows in warmer temperatures and is more tolerant of lower oxygen levels than many other species.
This alien species is another type of hot water. In fact, when the temperature drops below 50 degrees, no more flaky white fillets. The production facilities are mostly indoor and often greenhouse structures in which the fish consumes tiny particle residues, which often come from water that comes from other aquaculture or hydroponic operations.
According to the United States Trout Farmers Association, the US grew 53 million pounds of trout in 2008, mostly rainbow trout, for the most part for table dishes. Trout growing requires a lot of maintenance and good quality, oxygen-rich cold water. Typically, the temperature on running water running tracks should remain below 70 degrees
4. Yellow perch
Although it is a smaller fish, yellowfish fillets are highly valued. There are several pros for this cold water fish farming in the U.S., such as their ability to train well to feed and tolerate crowded conditions. However, the timing of production shifts and spawning inconsistencies can make farming difficult.
In every company there is a high concentration of organisms and with it the possibility that something goes wrong. For example, there is concern that salmon in net pens in the ocean could put the wild population at risk of disease. However, fish farming in the United States certainly helps supply meet demand. It also relieves pressure on some of our natural resources and can help protect fish, for example when buying your fishing license.
