摘要
日本对虾 (Penaeusjaponicus)仔虾体全长 (11 7± 1 0 )mm ,分别置于 2 4,2 0 ,18,16 ,14 5 ,13℃水槽中培养 ,经 10d观察的结果 :仔虾成活率与水温呈负相关 ,依次为 0 12 ,0 2 8,0 39,0 5 3,0 5 3,0 6 0 ;长度增长率与水温呈正相关 ,依次为 0 2 7,0 19,0 12 ,0 0 9,0 0 4,0 0 1。认为仔虾放流海区水温应 >16℃。
The postlarva of Penaeus japonicus ,which average length was 11 7±1 0mm,were cultured in water troughs under the temperature of 24,20,18,16,14 5,13 ℃ for ten days.The results showed that there was reverse relations between the survival rate of postlarva and temperature,the survival rate was 0 12,0 28,0 39,0 53,0 53,0 60 in the preper order.The body length growth rate increased with temperature,was 0 27,0 19,0 12,0 09,0 04,0 01 respectively,The suitable coastal water temperature for releasing postlarva of Penaeus japonicus should be over 16 ℃
