Effect of Applying Tα1 Spirulina to Feed in Juvenile Abalone Cultivation

在8口23.2 M2的池中,于水温12.5--17.7℃、盐度30的传统养殖模式下,研究饲料中定量添加Tα1螺旋藻喂养鲍苗的培育效果。试验组和对照组分别投放壳长(3.68±0.04)MM和(3.66±0.07)MM,密度(5755±429)粒·M-2和(5 733±169)粒·M-2的鲍苗,经过133 d的养殖,鲍壳长、成活率、日增长分别达到(15.65±0.19)MM和(15.08±0.63)MM、(93.57±0.68)%和(89.25±2.48)%、(90.04±1.49)μM·d-1和(85.81±4.48)μM·d-1。结果表明:添加Tα1螺旋藻培苗,可显著提高鲍苗培育成活率(P0.05);且壳色泽好、规格较整齐。经酶联免疫吸附法(ElISA)检测鲍苗体内的胸腺素α1含量也表明,添加Tα1螺旋藻能明显提高鲍苗体内的胸腺素α1含量(P 0.05).The color of shell and uniformity of size were better in treated group than in control.With enzyme-linked immunosorbent assay(ELISA),it was found that adding Tα1 Spirulina in feeds enhanced the content of Tα1 in juvenile abalone(P<0.05).科技部星火计划项目(2008GA721002);厦门市科技计划项目(3502Z20073008
