SGR is calculated using the formula SGR(%) = LOG e closing fat in the fish – Log e First fat from the fish/ range of days x a hundred. PWG is calculated utilizing the components PWG(%) = Closing fat on the fish- initial pounds/ Preliminary bodyweight x a hundred. FCR is determined by dividing the dry feed bodyweight offered because of the moist bodyweight in the fish.
The biofloc farming system is usually a technology that manipulates the environment by relying on oxygen provide and making use of microorganisms, which right contribute to bettering the digestibility of fish feed. When it comes to land spot ratio, one particular biofloc unit measuring 10 cubic meters may be used for breeding 1,000 fish.
Sustainable biofloc technology can gain poor farmers who earn their livelihood through fish farming, supplying a more efficient and cost-successful strategy to sustain their company.
Quite a few a time, the contractors are migrant laborers who pool in revenue for nets and transportation and divide the profit made from offering the fish. As a result, fish farming and its trade are supporting modest-scale business owners also.

A Biofloc system needs about six milligrams of oxygen for each liter for each hour, and at least thirty horsepower aerators for every hectare is usually recommended to begin with. Paddle-wheel aerators needs to be set up strategically to make a recent during the pond.
