摘  要：
利用杂交结合选育的方法对我国南方主要鲍鱼养殖品种杂色鲍进行了育苗试验。试验共设置2个杂交组合,每个组合分5个试验平行组。结果表明,2个组即TW♀×HN♂和TW♂×HN♀都取得了良好的育苗效果,其受精率分别为(97.23±1.52)%和(96.30±2.25)%;幼体附着率分别为77.02%和76.69%;幼体存活率分别为66.39%和66.89%;稚鲍壳长日增长分别为136.6μm和133.8μm。剥离60 d后,2个组合稚鲍的存活率分别达到了64.1%和74.2%,体现出良好的杂种优势和对环境的适应能力。TW♀×HN♂组合在受精率、幼体附着率和稚鲍壳长日增长率都高于其反交组合TW♂×HN♀,而幼体和稚鲍的存活率都低于反交组合,但方差分析表明2个组合正反交的育苗效果在受精率、幼体附着率、幼体存活率和稚鲍壳长日增长率上无显著性差异(P>0.05),但在稚鲍的存活率上存在显著性差异(P<0.05)。

摘  要：
The artificial breeding of Haliotis diversicolor which is a main aquaculture species in the south china was studied by hybridization and selection between Hainan stock and Taiwan stock.The experiment was arranged two hybrid combinations,and each combination had five repetitive groups.The experimental results of two hybrid combinations(TW♀×HN♂ and TW♂×HN♀)were both good;The fertility rate was(97.23±1.52)% and(96.30±2.25%) respectively;The larval averaged settlement rate was 77.02% and 76.69% respectively;and the growth rate of juvenile abalones was 136.6 μm and 133.8 μm per day respectively.The survival rate of juvenile abalone of two hybrid combinations reached 64.1% and 74.2% respectively after the juvenile abalone had been stripped for 60 days.It exhibited good hybrid vigor and the ability to adapt to the environment.The former combination had higher fertility rate,higher larval averaged settlement rate,and higher growth rate of shell length than the later one,but lower survival rate of juvenile abalone and the larval abalone than the latter one.However,the ANOVA analysis showed that there was no significant differences(P>0.05) for the result of the fertilization rate,the larval averaged settlement rates,the larval averaged survival rates and the growth rates of juvenile abalone between two combinations,and significant differences(P<0.05) in the survival rate of juvenile abalone.
