| 摘 要： | 1992年始于福建和粤东、1993年流行于全国沿海地区的大面积对虾暴发性流行病,使我国养殖对虾总产量由1992年的22×104t,锐减到1994年的5×104t,给沿海地区对虾养殖业造成重大损失1-4]。到2001年,我国对虾产量已经恢复到30×104t,主要得益于广东、海南和广西3省区的对虾养殖得到恢复和发展,而我国其他对虾养殖省区对虾产量仍没有恢复到1992年水平。近年来,我国学者在对虾养殖和病害控制等方面做了大量工作,特别是对虾病毒病的研究取得了显著进展5-7]。为探寻更有效的对虾健康养殖模式,有效控制病害的暴发流行,笔者在海南莺歌海洋生物技…

| Abstract: | This present paper studied the technological characteristics of seawater treated by sand filtering , net filtering and reserve2water disinfection. The results showed that after treatment the average filtering ratio of phytoplankton was 89. 98 % , and that of
zooplanktonwas89.5%; thatitcanisolatetheotherspeciesofshrimpandcrabbythefilteringnetof morethan40mesh,anditwas
difficult for Copepoda to pass through the filtering net of more than 60 mesh ,so it can block the horizontal disseminate pathway of WSSV ; and that 6 ?10 6 of the efficient chlorine can kill Copepoda but most aquatic creatures were dead in the water treated by 10
?10 6 of the efficient chlorine , and it can transfer algae after killing the harmful creatures by using bleaching powder when there was
reserve water. The result of water culture for 4 days , in out2seawater and the water treated with sand filtering or net filtering of 60
mesh or 6 ?10 -6of efficient chlorine , showed that the species and quantity of plankton were the most by out2sea2water culture , and it reduced respectively in the water treated by filtering with 6 mesh ,sand filtering and 6 ?10 -6 of efficient chlorine. |
