摘　　要：人工养殖条件下维持豹纹鳃棘鲈(Plectropomus leopardus)的体色是决定经济价值的关键,所以本文设计不同梯度光照强度区间的养殖环境,观察豹纹鳃棘鲈生长情况和体色变化情况。从试验结果可以看出当豹纹鳃棘鲈处于50~300 lx光照强度区间内,会一直维持较快的生长速率,体长、体重增加速率高于其他光照强度区间;而光照强度处于300~700 lx区间时,在养殖周期内积累的红色素含量最多,观察到明显的体色变化,即光照强度确实会影响豹纹鳃棘鲈色素累积,改变体色。Under artifical culture environment,maintaining the body color of Plectropomus leopardus is crucial to its economic value,for that reason this paper makes a study of the growth rate and accumulations of pigment of Plectropomus leopardus in different light intensity.The test result manifests that Plectropomus leopardus which lives in 50~300 lx light intesnsity of culture environment will maintain a fast growth rate and the growth rate of body length and weight is higher than others;while,when environmental light intensity range is 300~700 lx,Plectropomus leopardus will accumulate more red pigments and change body color obviously.Light intensity did affect the accumulation of pigment and the change of body color of Plectropomus leopardus.
