persian sturgeon (acipenser persicus) is one of the most important fish in caspian sea and demand for its fillets is considerable, study to improve the packaging and protect their quality during storage is necessary. in this study persian sturgeon fillets were packed under 30% vacuum then freezed and effect of this packaging method on decreasing and delaying lipid rancidity was studied by measu...

Immersing Siberian sturgeon fry of an average body mass of 40 ± 4 g in epin solution (0.1 mg l -1 ) resulted in an increase of ceruloplasmin level over the entire experimental period (P < 0.001). The differences between the treated and control groups gradually increased reaching the maximum in the fourth and fifth weeks of the study when average levels of ceruloplasmin in the epin-treated group...

persian sturgeon (acipenser persicus) is a valuable fish caught in the caspian sea. in this study, effect of frying, the most common cooking methods on nutritional properties of the persian sturgeon fillet were investigated. the raw and fried samples were analyzed for amino acid composition, protein and fat content, in vitro digestibility and nutritional parameters. the results showed that the ...

lactic acid bacteria are characterized as gram-positive, usually non-motile, non-sporulating bacteria that produce lactic acid as a major or sole product of their fermentative metabolism. in this study, the presence of lactobacilli were investigated in the intestines of beluga ( huso huso) and persian sturgeon ( acipenser persicus ), inhabiting caspian sea. the obtained data showed that various...

The lake sturgeon, Acipenser fulvescens, belongs to one of the few extant nonteleost ray-finned fishes and diverged from the main vertebrate lineage about 250 million years ago. The aim of this study was to use this species to explore the peripheral neural coding strategies for sound direction and compare these results to modern bony fishes (teleosts). Extracellular recordings were made from af...

–Growth rates of juvenile lake sturgeon (initial weight 8 to 9 g, temperature 17.5° C), fed twice a day on brown worms for 56 days increased from -1.5% BW/d (% body wet weight/day) at zero ration to 2.6% BW/d at a ration of 13.2% BW/d. Maintenance ration was 1.6% BW/d. Fish fed larger rations had higher energy densities and lower water content. Appetite (average volitional daily food consumptio...
