Having said that, fish species for example tilapia and carps, and shrimps including pink, brine, and pacific whiteleg shrimp which can be physiologically tailored to digest microbial protein acquired from biofloc use are usually suitable for biofloc systems (Emerenciano et al. 2013; Hargreaves 2013). Quite the opposite, biofloc systems will not be ideal for fish species which include channel catfish and hybrid striped bass and also for prawns such as huge tiger prawn and big freshwater prawn.

समाधान: नियमित पीएच परीक्षण और कार्बन स्रोत का संतुलित उपयोग करके उन्होंने समस्या का समाधान किया।

Overall variable cost per hectare was maximum on compact fish farms, accompanied by medium and enormous farms which show the economies of scale.
PER is calculated given that the ratio from the wet weight of your fish to your crude protein feed supplied. Ultimately, the survival price is calculated utilizing the components Survival price(%) = Total range of Harvested Animals through the fish culture/ Whole number of stocked fish x one hundred.
Based on what kind of fish or crustacean you are farming, Biofloc may also deliver supplemental feed to the farmed species. The microbial Local community might be a good source of nutrients For numerous filter feeders for example shrimp.
Sustainable Biofloc Fish Farming is a approach that entails cultivating fish in tanks with biofloc technology that helps to maintain h2o high quality and cut down the amount of h2o required.
