Effects of Different Carbon Sources on Growth and Some Innate Immune Responses of Russian Sturgeon (Acipenser gueldenstaedtii) in Biofloc Systems

open access: yesMarine Science and Technology Bulletin, 2023
The Russian sturgeon (Acipenser gueldenstaedtii) species is in high demand owing to its valuable caviar. Therefore, it is in danger of extinction. Since the Russian sturgeon reaches sexual maturity late in its life cycle, this species has a high economic

Effects of starvation and feeding strategies on hematological and biochemical indices in Russian sturgeon Acipenser gueldenstaedtii [PDF]

open access: yesتغذیه آبزیان, 2021
The effects of feeding strategies on cytological and biochemical indices in juvenile Russian sturgeon were studied. For this, 180 Russian sturgeons (77 ± 0.33 g) were stocked in three treatments with 20 fish in each tank and three replicates.
