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.
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.
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.

The rohu is a large, silver-colored fish of typical cyprinid shape, with a conspicuously arched head. Adults can reach a maximum weight of 45 kg (99 lb) and maximum length of 2 m (6.6 ft), [2] but average around 1 ⁄ 2 m (1.6 ft). [citation needed]
Austria was the first to set an organic standard, implementing it for the common carp in 1995. In 2000, France and the UK established their own national organic standards for fish, and an international standard was established by the IFOAM. [38]: 550 Denmark: Rainbow Trout. Organic production ~400 tonnes (1% of total trout production) [21] UK:

Harvest – the number or weight of fish caught and retained from a given area over a given period of time. Note that landings, catch, and harvest are different. Hatchery – the process of cultivating and breeding a large number of juveniles in an enclosed environment. The juveniles are then released into lakes, rivers or fish farm enclosures.
