The Influence of Photoperiod in Farming Beluga Sturgeon (Huso huso): Evaluation by Growth and Health Parameters in Serum

F. Askarian and A. Kousha    

Abstract: Data on the concentrations of some blood constituents of reared Beluga sturgeon, Huso huso, including Serum cortisol, glucose, triglyceride, cholesterol, osmolality, Na+, K+, Ca2+, ALP that reared under different light regimes were measured. The light regimes were consist of natural photoperiod (NP), continuous dark (0L:24D), continuous light (24L:0D) and long day regime (16L:8D) and tested on 4 group of 30 one year old reared Beluga for 6 month which sampled four times during the experiment. No significant difference in serum cortisol and ALP levels was found between treatments (p>0.05). Elevations of serum cortisol, glucose, cholestrol and triglyceride concentrations were reported in continues dark regime. Increase of serum osmolality, Na+, K+ and decrease of Ca2+ were also associated with increase of cortisol levels. Results are compared with the few data available in condroestean fish and with those on teleosts.
