摘要 为实现白刺参苗种的规模化生产,需查明各环境因子对幼虫生长及存活的影响。通过比较不同盐度(25、29、33和37)、温度(19、21、24和27℃)和培育密度(0.1、0.2、0.4和0.6个/mL)条件下,白刺参与普通刺参幼虫的生长和存活,筛选白刺参幼虫的最佳培育条件。结果表明,在盐度为25时,白刺参幼虫的成活率和体长值都较高;在温度为19℃时,白刺参及普通刺参幼虫的生长速度较快,成活率较高;在培育密度为0.6个/mL时,白刺参幼虫生长速度快、成活率高。盐度25、温度19℃与培育密度0.6个/mL是白刺参幼虫生长最适宜的培育条件。 In order to raising lavae of white race sea cucumber (AIoostichopus japonicus) m targe scales, the survival and growth of larvae under different environments should he investigated. In present study, the larval survival and growth of white and ordinary A. japonicus at different salinities (25, 29, 33 and 37), temperatures (19, 21, 24 and 27 ℃),and stocking densities (0.1, 0.2, 0. 4, 0.6 ind/mL) were compared in order to optimize rearing condition. It was found that salinity 25, 19 ℃ and stocking density 0. 6 ind/mL are optimal; high survival and growth were observed.
