Abstract

Indoor recirculating aquaculture systems make light control possible and enable the usage of specific coloured lights to promote the growth and immunity of aquaculture species. Five different LED wavelengths (white light [460 nm], red light [622 nm], green light [517 nm], blue light [467 nm], and the dark) were used in this study to evaluate growth and immunity in the glass eel stage of two high-valued anguillid species, Japanese eel (Anguilla japonica) and giant mottled eel (A. marmorata). There were no significant differences in growth of the Japanese eel among the groups after 12 weeks of feeding (p > 0.05); the survival rate of each group was over 95%. The giant mottled eel showed better growth in total length and body weight in the red light and dark groups (p < 0.05). Expression levels of immune-related genes were not significantly different between each group of the Japanese eel and the giant mottled eel (p > 0.05). The growth of the Japanese glass eel was not significantly sensitive to different LED wavelengths, while the giant mottled glass eel showed better growth under red light and dark environments. Neither eel species showed significant differences in innate immunity under different LED wavelengths.

不同LED光谱对日本鳗鲡和巨型斑鳗生长和免疫的影响

室内循环水产养殖系统使光线控制成为可能，并能够使用特定的彩色灯光来促进水产养殖物种的生长和免疫力。在本研究中，使用了五种不同的LED波长（白光[460nm]、红光[622nm]、绿光[517nm]、蓝光[467nm]和黑暗）来评估两种高价值鳗属物种日本鳗（安圭拉-日本鳗）和巨型斑点鳗（A.marmorata）在玻璃鳗阶段的生长和免疫力。饲养12周后，日本鳗的生长在各组之间没有显著差异（p>0.05）；各组生存率均在95%以上。在红光组和黑暗组中，巨斑鳗的总长度和体重都表现出更好的生长（p<0.05）。日本鳗和巨斑鳗各组的免疫相关基因表达水平没有显著差异（p>0.05）。日本玻璃鳗的生长对不同的LED波长不显着敏感，而巨大的斑点玻璃鳗鱼在红光和黑暗环境下表现出更好的生长。在不同的LED波长下，这两种鳗鱼的先天免疫力都没有显著差异。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
