Snubnose pompano (Trachinotus blochii) are widely cultured in the world. Light colours are among factors affecting fish performance in captivity. Snubnose pompano larvae often reared under white light. However, no study supports its choice or informs the extent of its effect or its constituent colour. The study investigated the influence of green, blue, yellow, purple, and white lights on growth, survival, cortisol, body composition, and digestive enzymes activities of one-day post-hatch Snubnose pompano larvae reared in light magenta tanks under a photoperiod of 24 Light:0 Dark hours for 25 days. Overall, the best growth performance of snubnose pompano larvae was in purple and white, and green lights during early and late larval stages, respectively. White light promoted survival rate while that of green light reduced. Larvae were less stressed and had enhanced body contents under white and purple light environments. Purple and yellow lights influenced low trypsin and pepsin activities. The study reports for the first time the effect of the light colour environment on the digestive enzyme activities and body composition of the finfish larvae. Generally, the study provides novel insights on optimal light colour in the larval rearing protocol of this species. Through this study, the use of white light during the first feeding (zero to four days post-hatch) and purple light in later stages (five days post-hatch until metamorphosis) is encouraged while discourages green and yellow lights in the larval rearing of Snubnose pompano.

Snubnose pompano ( Trachinotus blochii) 在世界范围内被广泛培养。浅色是影响圈养鱼类性能的因素之一。Snubnose pompano 幼虫通常在白光下饲养。然而，没有研究支持它的选择或告知其影响的程度或其组成颜色。该研究调查了绿光、蓝光、黄光、紫光和白光对浅品红色水箱中培育的孵化后一天的 Snubnose pompano 幼虫的生长、存活、皮质醇、身体成分和消化酶活性的影响。 24 光：0 黑暗时间 25 天。总体而言，金凤尾幼虫的最佳生长性能分别是紫光和白光，以及幼虫早期和晚期的绿光。白光提高存活率，而绿光降低。幼虫在白色和紫色光环境下压力较小，体内含量增加。紫色和黄色光影响低胰蛋白酶和胃蛋白酶活性。该研究首次报道了光色环境对有鳍鱼幼体消化酶活性和体成分的影响。一般来说，该研究提供了有关该物种幼虫饲养方案中最佳光色的新见解。通过这项研究，鼓励在第一次饲养期间（孵化后 0 到 4 天）和后期阶段（孵化后 5 天直到变态）使用白光，同时不鼓励在幼体饲养中使用绿光和黄光。斯努比诺。该研究首次报道了光色环境对有鳍鱼幼体消化酶活性和体成分的影响。一般来说，该研究提供了有关该物种幼虫饲养方案中最佳光色的新见解。通过这项研究，鼓励在第一次饲养期间（孵化后 0 到 4 天）和后期阶段（孵化后 5 天直到变态）使用白光，同时不鼓励在幼体饲养中使用绿光和黄光。斯努比诺。该研究首次报道了光色环境对有鳍鱼幼体消化酶活性和体成分的影响。一般来说，该研究提供了有关该物种幼虫饲养方案中最佳光色的新见解。通过这项研究，鼓励在第一次饲养期间（孵化后 0 到 4 天）和后期阶段（孵化后 5 天直到变态）使用白光，同时不鼓励在幼体饲养中使用绿光和黄光。斯努比诺。
