摘要
采用室内受控的实验方法研究了不同光照强度对刺参幼参生长的影响。实验设暗光、微强光、强光3个光照处理,同时每个光照处理组分别投喂两种饵料(人工配合饲料、人工配合饲料加底栖硅藻)。研究结果表明,不同光照强度下,幼参的生长差异显著(P<0.05),每种饵料处理下强光处理组幼参的特定生长率和日增重明显高于暗光处理组,而相同光照强度下两种饵料处理对幼参生长的影响差异不显著(P>0.05)。3个光照处理下幼参的特定生长率平均分别为0.26%、0.63%、0.98%/d,日增重为0.53、1.39、2.26 g/d。
The effects of three light intensities（0. 77-5. 57lx, 650-2 900lx, 2 700-11 000lx）on the growth of juvenile sea cucumbers Apostichopus japonicus were studied. Two diets were fed to the animals in each light intensity treatment groups, respectively. Results showed that the daily weight gain （DWG） and specific growth rate （SGR） of juvenile A. japonicus were significantly affected by light intensity （P〈0. 05）. The SGR and DWG of the higher light intensity treatments were greater than the lower light intensity treatments. But the DWG and SGR were not significantly affected by feedstuff （P〉0.05）. The SGR of different light intensity treatments was 0.26%,0.63% and 0.98%/d, respectively, and the DWG was 0.53,1.39 and 2.26 g/d, respectively.
