白鲟被认为是鱼子酱生产中最重要的物种。研究光周期调控对白鲟生长因子的影响。6个光周期（光：暗循环）包括自然光周期（对照）、24L：0D、16L：8D、12L：12D、8L：16D和0L：24D，三个重复。处理5（8L：16D）在73 d后的最终增重最大（2194.4 g），处理4、3和1（12L：12D、16L：8D和对照）可被认为是白鲟较好的光周期方案。持续光照（24L：0D）和持续黑暗（0L：24D）使鱼的最终体重分别降低到1804.2g和1976.1g，差异显著（P < 0.05）。光周期调控显著提高了白鲟的生长速度和食物转化率。
The beluga sturgeon is considered as the most important species for caviar production. This study aimed to evaluate effects of photoperiod manipulation on growth factors of beluga sturgeon. The six photoperiod regimes (light: dark cycle) including natural photoperiod (control), 24L : 0D, 16L : 8D, 12L : 12D, 8L : 16D and 0L : 24D with the three replicates. The treatment 5 (8L: 16D) gained the greatest final weight (2194.4 g) after 73 rearing days and besides, the treatments 4, 3 and 1 (12L : 12D, 16L : 8D, and Control) can be considered as the good photoperiod regimes for beluga sturgeon. The continuous light (24L : 0D) and continuous dark (0L : 24D) significantly (P < 0.05) reduced the final weight of fish to 1804.2 g and 1976.1 g, respectively. Regulated photoperiod significantly improve growth rate and food conversion ratio of beluga sturgeon.
