红罗非鱼的养殖正在迅速增加。然而，由于缺乏环境变化导致的皮肤颜色和色素沉着差异的明确遗传基础信息，其商业化养殖发展受到挑战。研究了光周期（光：暗，光：暗）对马来西亚红罗非鱼生长和皮肤颜色变化的影响。在自然光周期（13L:11D，对照）、延长光照（24L:0D）和延长黑暗（0L:24D）条件下，分3个重复饲养180尾鱼，体重150.48±0.44 g，共78 d。延长光照和黑暗条件下的鱼的增重均显著高于自然光照条件下的鱼。在长时间黑暗条件下养殖的鱼腹部皮肤中酪氨酸酶水平显著高于其他两个光周期。相反，在自然光周期下养殖的鱼背部皮肤中半胱氨酸水平显著高于长时间光照和黑暗条件下养殖的鱼。长时间黑暗条件下，SRY相关HMG - Box 10 （sox 10）、酪氨酸（tyr）、酪氨酸相关蛋白1 （tyrp - 1）和溶质载体家族7成员11 （slc7a11）基因mRNA的相对表达量显著高于其他两个光周期。本研究表明，光周期对红罗非鱼的黑色素形成和生长有影响。了解光周期对红罗非鱼遗传基础的影响，将有助于红罗非鱼商业养殖发展的重要经济性状的选择育种计划。
Farming of red tilapia is increasing rapidly. However, its commercial farming development is challenged by lack of clear information on genetic basis for skin colour and pigmentation differences due to environmental changes. This study investigated the effects of photoperiod (light:dark, L:D) on the growth and skin colour variation of Malaysian red tilapia. A total of 180 fish weighing 150.48 ± 0.44 g were reared under natural photoperiod (13L:11D, control), prolonged lightness (24L:0D) and prolonged darkness (0L:24D) in three replicates for 78 days. The weight gain of fish cultured under both prolonged light and darkness were significantly higher than fish under natural photoperiod. The tyrosinase level in ventral skin was significantly higher for fish cultured under prolonged darkness condition than in the other two photoperiod regimes. Contrary, the cysteine level in the dorsal skin was significantly higher in the fish cultured under natural photoperiod than in prolonged light and darkness. The relative mRNA expressions of SRY‐related HMG‐Box 10 (sox 10), tyrosine (tyr), tyrosine‐related protein 1 (tyrp‐1) and solute carrier family 7 member 11 (slc7a11) genes were significantly higher in ventral skin of fish under prolonged darkness than the other two photoperiods. This study demonstrates that photoperiod has an impact on melanogenesis and growth of red tilapia. Understanding the effects of photoperiod on genetic basis of red tilapia will help in selective breeding programme of the important economic traits for the development of commercial red tilapia farming.
