Standard weight equation for largemouth bass [1] and burbot [2] (fish). Standard weight in fish is the typical or expected weight at a given total length for a specific species of fish. Most standard weight equations are for freshwater fish species. Weight-length curves are developed by weighing and measuring samples of fish from the population.
Although carnivorous farmed fish represented only 13 percent of aquaculture production by weight in 2000, they represented 34 percent of aquaculture production by value. [101] Farming of carnivorous species like salmon and shrimp leads to a high demand for forage fish to match the nutrition they get in the wild.
Fish farming or pisciculture involves commercial breeding of fish, most often for food, in fish tanks or artificial enclosures such as fish ponds. It is a particular type of aquaculture , which is the controlled cultivation and harvesting of aquatic animals such as fish, crustaceans , molluscs and so on, in natural or pseudo-natural environments.
The Texas Parks and Wildlife Department has released nearly 1 billion saltwater fish into Texas bays over the last 40 years — an effort to revitalize historic fisheries and recover native fish ...

Cobia, a warm water fish, is one of the more suitable candidates for offshore aquaculture. [1] [2] Cobia are large pelagic fish, up to 2 metres (6.6 ft) long and 68 kilograms (150 lb) in weight. They are solitary fish except when spawning, found in warm-temperate to tropical waters.
Fish are fed daily through the summer, at rates of 1-6% of body weight with pelleted floating feed. Catfish need about two pounds of feed to produce one pound of live weight. Mississippi is home to 100,000 acres (400 km 2) of catfish ponds, the largest of any state. Other states important in growing catfish include Alabama, Arkansas and ...
In some regions the fish can be raised in rice fields at planting time and grow to edible size (12–15 cm, 5–6 in) when the rice is ready for harvest. Unlike salmon, which rely on high-protein feeds based on fish or meat, commercially important tilapiine species eat a vegetable or cereal-based diet.
