摘要
采用金藻、金藻和云微藻、云微藻三组饵料分别投喂斑玉螺浮游幼虫 ,每天测定壳宽和存活率 .结果表明 ,1 0d后 ,投有金藻的两组存活率较高 ,生长较快 ,作者认为 ,金藻是斑玉螺浮游幼虫的适合饵料 .
Larvae of Natica tigrina (Roding)are divided into 3 groups,feeding on Isochrysis galbana,Isochrysis galbana and “Yunweizao”(Chlorophyta),“Yunweizao”(Chlorophyta),respectively to investigate the shell's width and survival rates every day. After 10d, experimental results show that survival rates and growth rates of the larvae feeding on Isochrysis galbana or Isochrysis galbana and “Yunweizao”(Chlorophyta). are higher, and Isochrysis galbana is fit for fodder of the larvae of Natica tigrina.
