摘要

由于商业上重要的温带鳗鱼供应减少，包括安圭拉marmorata Quoy&Gaimard，1824在内的热带物种正被作为替代品，以满足对鳗鱼产品的高需求。然而，其水产养殖的最佳生态条件仍然研究不足。本研究评价了马齿苋在苗圃培养中生长的最适盐度条件。在0、10、15、20和25ppt盐度下培养90天后，评估麋鹿的生长性能。结果表明，养殖盐度不影响成活率和饲料转化率。在15ppt和20ppt时，观察到体重增加百分比、比生长率和日长度增加显著改善。多项式二次回归分析表明，盐度为18.14ppt是黄鳝幼鱼生长的最佳盐度。这些发现可为发展热带黄鳝咸水育苗提供依据。

Optimum Salinity for Growth of Tropical Eel Anguilla marmorata Quoy & Gaimard, 1824 in Nursery Culture

Due to the reduced supply of commercially important temperate eels, tropical species including Anguilla marmorata Quoy & Gaimard, 1824 are being targeted as an alternative to satisfy the high demand for eel products. However, optimum ecological conditions for its aquaculture remained understudied. The present study evaluated the salinity conditions optimum for the growth of A. marmorata in the nursery culture. Growth performances of elvers were assessed after 90 days of culture at 0, 10, 15, 20 and 25 ppt salinity. Results showed that survival and feed conversion ratio were not influenced by the culture salinity. Significant improvement in per cent weight gain, specific growth rate and daily length increase were observed at 15 and 20 ppt. Polynomial quadratic regression analysis indicates that salinity of 18.14 ppt is optimum for the growth of this eel in nursery culture. These findings can serve as a basis for developing brackish water nursery culture of the tropical eel A. marmorata .

期刊介绍： The Asian Fisheries Science (AFS) was first published in 1987. It is an open access SCOPUS indexed publication of the Asian Fisheries Society. Four regular issues are published annually in March, June, September and December. In addition, special issues are published on specific topics. Full texts of the articles are available for free download and there is no publication fee. The journal promotes fisheries science which has an international appeal with special focus on Asian interests.
