Edible coatings of chitosan and fucoidan with crucian carp protein hydrolysate to extend shelf life of beluga sturgeon fillets.

This study investigates the problem of preserving the quality and shelf life of beluga sturgeon () fillets under refrigeration. The aim of the research is to evaluate the effectiveness of composite edible coatings made from chitosan and fucoidan, in combination with crucian carp () protein hydrolysate (CPH). Significant methodology includes the preparation of hydrolyzed proteins using the enzyme Alcalase for 90 min, followed by encapsulation within nanoliposomes.

Effects of dietary thiamin (vitamin B1) on the growth performance, serum biochemical factors, immune response, and antioxidant activity of great sturgeon (Huso huso) juveniles.

The present research evaluated the positive effects of dietary thiamin (vitamin B1) levels on the growth performance, serum biochemistry factors, immune response, and antioxidant activity of great sturgeon (Huso huso) juveniles. Thiamin was included in diets with levels of 0 (control, T0), 7 (T7), 15 (T15), and 25 (T25) mg/kg diet. Measurements of thiamin levels in diets indicated that they contained 1.
