摘要
将花尾胡椒鲷(Plectorbinchus cinctus)的受精卵在室内育苗池和室外大池不同环境下进行人工育苗比较试验，在26℃～28．8℃的水温条件下，室内培育盐度保持26左右，室外大池的盐度变动范围为26．2～22．9，经过36d的培育，结果显示：①在室内育苗池培育的鱼苗成活率最高为13．9％，最低为6．4％，平均为11．0％；室外培育的成活率仅为6％，室内培育相对室外培育的成活率增加45．5％。②室内培育的鱼苗平均体长为34．5mm，室外培育为52．1mm，室外培育相对室内培育鱼苗体长增加33．6％。③活力试验。室内培育的鱼苗成活率最高为94．8％，最低82．4％，平均为90．9％，而室外培育的鱼苗成活率则达到99．6％，室外培育相对室内培育鱼苗活力试验的成活率增加8．0％。因此，室内培育鱼苗的成活率相对较高，但生长缓慢，活力较差；室外培育鱼苗成活率相对较低，但生长快，活力强。
A comparative experiment on artificial breeding of Plectorbinchus Cinctus has been done in indoor and outdoor big banks. The salinity is about 26 indoors, and varies from 22.9 to 26.2 outdoors. The water temperature is between 26 ℃ ~ 28.8 ℃. The fry is cultured in this environment for 36 days, and the results show: ①The highest and the lowest survival rates of the fry indoors are 13.9 % and 6.4 % respectively, and the mean survival rate is 11 %. The mean survival rate outdoors is 6 %. The survival rate indoors is higher than that outdoors. ②The mean body length of the fry indoors is 34.5 mm, as compared to 51.2 mm outdoors. The mean body length outdoors is 33.6 % higher than that indoors. ③Vitality test, the highest and the lowest survival rates of the fry indoors are 94.8 % and 82.4 % respectively, and the mean survival rate is 90.9 %. The mean survival rate outdoors is 99.6 %. The survival rate outdoors is 8.0 % higher than that indoors. In conclusion, the survival rate indoors is higher than that outdoors, but the growth speed and vitality indoors are lower than those outdoors.
