摘要:
在6口培育池中,投放平均壳长(16.3±0.2)mm、密度1 633粒m-2的鲍苗,在水温19.6~26.0℃、盐度30的条件下,比较添加微生态制剂的节水模式与现有模式对鲍苗培育的影响。经过60 d的培育,试验组和对照组的鲍苗壳长、成活率、日增长分别为(21.57±0.40)mm和(23.17±0.38)mm、(93.69±0.46)%和(91.61±1.55)%、(87.77±4.21)μmd-1和(14.42±6.76)μmd-1。结果表明:添加微生态制剂培育鲍苗可节水75.76%,节水效果显著(P0.05),且有利于减轻水交换带来的不利影响,提高鲍苗培育成活率(P0.05)。
Abstract:
The abolone seedlings at shell length of(16.3±0.2)mm,density of 1633/m2 have been cultivated in 6 pools at the condition of 19.6-26℃,salinity 30,and the effect on abalone seedling culture between two modes have been compared,the water-saving mode of adding microbiological agents and the traditional mode.After 60 days of culture,the shell length,survival rate and average daily gain of the abalone seedlings between the test group and the control group were(21.57± 0.40)mm and(23.17±0.38)mm,(93.69±0.46)% and(91.61±1.55)%,(87.77±4.21)μmd-1 and(114.42±6.76)μmd-1.The result showed that: after adding micro-biological agents,75.76% of cultivation water was saved,the effect was significant(P0.05),and it can help reduce the adverse effects of water exchange,and improve the survival rate of abalone seedling cultivation(P0.05).
