Dietary copper requirement of juvenile Russian sturgeon Acipenser gueldenstaedtii
Aquaculture, 2016Abstract To quantify the dietary copper (Cu) requirement of Russian sturgeon Acipenser gueldenstaedtii, copper sulfate (CuSO4·5H2O) was added into the basal semi-purified diet at seven levels 0, 1, 2, 4, 6, 8 and 16 mg Cu kg− 1 diet yielding the actual dietary values of 0.3, 1.5, 2.4, 4.4, 6.2, 8.3 and 16.1 mg Cu kg− 1 diet, respectively.

Sexual development in Russian sturgeon (Acipenser gueldenstaedtii) grown in aquaculture
2008The Russian sturgeon (Acipenser gueldenstaedtii) has been introduced into aquaculture in recent years, following the decline of natural populations and the resultant increases in the price of caviar. In nature, males and females of this species mature sexually after 8 to 13 and 10 to 16 years, respectively. Fertilized Russian sturgeon eggs were bred up

Biology of reproduction, 2014
Among sturgeons, the occurrence of individuals with gonads containing both testis and ovary components is considered pathological, and such fish are described as intersex individuals or intersexes. Intersexes are observed in both wild and cultured populations of sturgeon, usually at low frequencies.
