RESEARCHES ON MEAT QUALITY OF STURGEONS REARED IN RECIRCULATING AQUACULTURE SYSTEMS

This work brings some qualitative results of sturgeon meat reared under different conditions of growth, namely recirculating aquaculture system and natural environment. Biochemical composition of meat was determined by classical methods of quantification for the proteins -Kjeldahl method, for the fat - Soxhlet method and for the dry matter and ashes by dehydration, respectively by calcination. Analysis of the main macronutrients in the analyzed sturgeon carcass, proteins and fats, showed a superiority of their concentration in fish meat from the recycled system, the results being confirmed by repetition. Achieve of higher percentage of protein and fat in fish flesh is the main purpose of the intensive aquaculture in confined and controlled spaces which is why this work represents a further proof that recommends these technologies
