[Effect of photoperiod on growth, physiological and hematological indices of juvenile Siberian sturgeon Acipenser baerii].
The effect of photoperiod on the growth of juvenile Siberian sturgeon Acipenser baerii has been studied in aquarium experiments. The maximum growth rate of juvenile Siberian sturgeon was observed under 12, 16, and 24 h photoperiods. This was accompanied by high respiratory rate and total food consumption and conversion. Rearing in the dark significantly decreased these indices. The hematological indices were within the normal range under optimal photoperiodic conditions. Pronounced neutrophilia and leukopenia were observed in the absence of light.
