| 摘 要： | 本文就温度，盐度以及不同降低盐度方法对鲈于仔鱼的生长及存活进行实验，经一星期的培养，结果表明，１；钙鱼仔鱼在盐度３０－３‰的海水中都能生长，以２０‰的存活率最高达９９％。２．每经６小时逐渐降低盐度５‰的仔鱼存活率高于大幅度骤降盐度。３．温度１４．７－１４．９℃和１８．３－１９．７℃，以盐度３０‰生长快，５‰生长缓慢。

| Abstract: | The effects of temperature, salinity and difference method of declining salinity on growth and sarvival rate of pre-larvae Japanese sea bass are studied. Resutts show: (1) The pre-larvae can grow at salinity 3 - 30. The maximum sarvival rate occurs at salinity 20. It is 99%; (2) The survival rate of larvae at salinity decreased by 5 per 6 hour is higher thah that at salinity suddenly decreased; (3) At temperatare 14.7-14.9C and 18. 3-19.7 C ithe larvae grow fast at salinity 30 and slow at salinity 5. At temperatare 24. 5-25.0C, the larvae grow fast at salinity 5 and slow at salinity 3. |
