杂色鲍在高密度养殖条件下的生长速率

本文报道了在人工高密度养殖条件下，杂色鲍（Ｈａｌｉｏｔｉｓｄｉｖｅｒｓｉｃｏｌｏｒ）的相对生长率、特定生长率及生长速度与饵料、水温等环境因子的关系。结果表明，杂色鲍的饵料系数为１３．６６，饵料转化率为０．０７３２，增重倍数为６．０３。体重与体长生长速率（７～１２月）关系式为Ｗ＝０．３０３９Ｌ－６．１８８７。

Growth rate of Haliotis diversicolor in intensive culture

Haliotis diversicolor juveniles were cultured from JulDec,1996,under high density condition.The monthly body length growth rate averaged 28.62% and the specific length growth rate averaged 18.23%.The monthly body weight growth rate averaged 14.73 % and the specific weight growth rate averaged 53.32%.The individal body weight increased 6.03 times. The growth peak of body length emerged between SeptOct and that of body weight emerged between AugSept. There also existed some relationships between the growth rates of body length and body weight and among the growth rate,food ingestion and environmental factors. Under given environment conditions,the mean food coefficient of the abalone was 13.66 and the food transfer coefficient was 0.073 2. The relationship formula between body length and body weight was W=0.303 9L-6.188 7 during JulyDecember.
