SGR is calculated using the system SGR(%) = LOG e closing excess weight from the fish – Log e initial fat of the fish/ quantity of days x one hundred. PWG is calculated utilizing the components PWG(%) = Remaining fat of the fish- First bodyweight/ First pounds x a hundred. FCR is determined by dividing the dry feed bodyweight provided via the damp body weight from the fish.
By protecting the carbon to nitrogen ratio by introducing carbon sources, microbial protein production with superior quality is realized. Drinking water excellent is Increased by biofloc systems. Together with the drinking water quality, there will also be a fantastic supply of nutrients accessible to the fish, which can help their healthful expansion and increases their disease resistance.

The main reason Erik undertook this transformation in his enterprise was that he considered the biofloc system far more efficient in maximizing land use and reaching increased harvest yields.
Biofloc output can lessen mortality, maximize larval growth and strengthen development prices in cultured species. It is actually an eco-pleasant cultural system.
For every is calculated as the ratio with the wet body weight in the fish to the crude protein feed specified. Eventually, the survival rate is calculated using the method Survival charge(%) = Whole amount of Harvested Animals from the fish culture/ Complete variety of stocked fish x one hundred.
