SGR is calculated utilizing the system SGR(%) = LOG e remaining fat with the fish – Log e First bodyweight with the fish/ range of times x one hundred. PWG is calculated utilizing the formulation PWG(%) = Remaining bodyweight from the fish- initial excess weight/ First bodyweight x a hundred. FCR is determined by dividing the dry feed body weight provided from the soaked bodyweight from the fish.
The flocs themselves are protein-wealthy and supply fish and shrimp with a very good source of nutritional vitamins and phosphorous. The authors reveal that letting the microbial flocs to proliferate can enhance water high quality and immobilise toxic nitrogen.
Biofloc fish farming is a new and sustainable system that aims to further improve water high quality and raise the volume of fish grown in a little space.

All fish species will acknowledge supplemental feeds. But the bottom and h2o column feeding species can obtain probably the most profit if the level of organic and natural product during the pond is proscribed.
Most fish species will get pleasure from the improved h2o good quality of Biofloc systems, and you should select species capable of Biofloc self-feeding and digestion. Entire or partial filter feeders make the most of the additional protein produced by these species.
