| Abstract | ||
| The cultivation of sturgeon larvae in biofloc-based systems is recognized as a promising and sustainable approach in aquaculture. Biofloc technology, utilizing a diverse community of microorganisms, including nitrifying and heterotrophic bacteria, improves water quality and aids in the conversion of toxic nitrogen compounds, thereby enhancing overall environmental conditions. This system also meets the nutritional requirements of sturgeon larvae by providing essential nutrients through biofloc, which contains beneficial bacteria and algae. Effective nutritional management, starting with live feeds such as Artemia nauplii and gradually transitioning to formulated diets, ensures optimal growth and survival. Continuous monitoring of water quality parameters—such as temperature, pH, ammonia, nitrite, and nitrate—and proper management of biofloc, including aeration and the addition of carbon sources, are crucial for maintaining a healthy environment for the larvae. Future research is needed to refine nutritional guidelines and develop specialized diets for different sturgeon species to promote sustainable production and the conservation of these endangered fish. By implementing comprehensive monitoring and control strategies, farmers can optimize growth conditions, improve fish health, and enhance the overall efficiency of biofloc systems in sturgeon aquaculture. | ||
