摘要
本文研究了水质盐度与三角帆蚌幼蚌生长的关系。结果表明:盐度对三角帆蚌幼蚌生长有明显的影响,两者间的关系为:Y=0.241x·e^(-2.424 7x)(r=-0.9878)。盐度为0.15～1.5时比较适宜于三角帆蚌幼蚌的生长,最适宜范围为0.3～0.7,当盐度为1.5～2时,则随盐度的增加,其生长率明显下降,致死盐度大致为3～5。经不同盐度驯养的三角帆蚌幼蚌对盐度的反应也有所不同。
This paper deals with the relationship between the growth of Hyriopsis cumingii larvae and salinity. The results indicated that salinity could notably affect the growth of Hyriopsis cumingii larvae. The relationship beween the growth rate and salinity was:
Y= 0.241 x · e-2.4247x (r= 0.9878) . The suitable salinity range was about 0.3-0.7 and the larvae could grow adequately even below 1.5. The death salinity was about 3-5. Hyriopsis cumingii larvae, salinity, growth
