摘要 在水温29±1℃,光照强度500lx的条件下,研究了不同光周期对中华鳖稚鳖的最大日摄食量、最大日摄食率、特定生长率、同化效率、消化时间和生长效率的影响。结果表明,光周期对中华鳖稚鳖的上述各指标均无显著影响。随体重的增加,中华鳖稚鳖的最大日摄食量逐渐增大,而最大日摄食率则逐渐减少。在人工养殖中华鳖稚鳖过程中。 The maximum food consumption, maximum daily ration level, specific growth rate, assimilation efficiency, passage time and growth efficiency of juvenile soft shelled turtle ( Trionyx sinensis ) were measured in different photoperiod.The experimental light intensity was 5001x and water temperature was 29±1℃. Results showed that photoperiod did not affect on the indices mentioned above significantly.With increasing of body weight, the maximum food consumption gradually increased while the maximum daily ration level decreased. It is supposed that the photoperiod is not an important influence factor to soft shelled turtles in the artificial growth environment.
