Abstract:
... This study set out to examine the effects of thyroxine (T4) on reproductive success of female Sterlet sturgeon broodstock and subsequent growth and development of the larval offspring. Fish received four intraperitoneal injections of coconut oil (controls), 1 mg T4/kg body weight (BW) in coconut oil (T₁) or 10 mg T4/kg BW in coconut oil (T₁₀) over a 170-day treatment period. Ovulation was induced ...
