摘要
本文研究了鲻鱼前期仔鱼在不同海水盐度条件下的生长和存活情况。结果表明:鲻鱼前期仔鱼生长与存活的适宜盐度范围为20-32‰;盐度低于20‰,随盐度下降,前期仔鱼存活率降低、生长速度趋慢;反之,盐度高于32‰,随盐度升高,前期仔鱼存活率降低、生长速度趋缓。
The studies on growth and survival of Grey mullet pre-larvae were conducted.The results show that,the optimum growth and survival salinity of pre-larvae is 20-32.When salinity is below 20,the lower salinity,the lower survival rate and the slower growth.On the contrary,when salinity is above 32,the higher salinity,the lower survival rate and the slower growth.
