Effects of River Hydrological Status on Gonadal Development of Breeding Population of Chinese Sturgeon …

Summary :The effect of two environmental factors (substrate type and water velocity regime) was studied in the ontogenetic migration intensity of kaluga, Huso dauricus, a protected species in the Amur River. Early-life stages studied were: free embryos = days 0–8; larvae = days 9–49; and juveniles = days 50–66. Effect of treatments on fish migration intensity was observed in circular channels, allowing migration in an endless stream.
