本文叙述了石鲽仔鱼经11天饲育试验,在—0.5℃、2.8℃、5.3℃水温条件下的生长和发育情况;同时,也叙述了在接近海水冰点(_1.8℃)和自然水温(13.6℃)条件下的补充试验情况。_0.5℃试验组,石鲽前期仔鱼依靠自体卵黄营养仍可发育和生长,但当自体卵黄营养耗尽后,则不能摄食,所以不能发育和生长,在2.8℃和5.3℃两个试验组的石鲽仔鱼,都能够正常发育和生长;在0℃—13.6℃水温范围内,石鲽仔鱼平均体长增长率随着水温的增加而增加;同时其随着水温和发育生长的不同而处于不同的行动姿态;石鲽仔鱼的生物学零度在0℃附近,其发育符合积温法则
This article describes the growth and development of the larvae of Shrimp larvae after 11 days of feeding at water temperatures of -0.5 ℃, 2.8 ℃ and 5.3 ℃. At the same time, ℃) and natural water temperature (13.6 ℃) under the conditions of the supplementary test conditions. _0.5 ℃ experimental group, prehistoric larvae rely on self-nutrition yolk can still develop and grow, but when the self-yolk nutrition exhausted, you can not feed, it can not develop and grow at 2.8 ℃ and 5.3 ℃ The average growth rate of larvae increased with the increase of water temperature in the water temperature range of 0 ℃ -13.6 ℃. At the same time, with the increase of water temperature and Different growth and development in a different gesture of action; Shijie larvae biological zero degrees near 0 ℃, its development in line with the law of accumulated temperature
