    摘要:

    比较运输方式及环境温度对合浦珠母贝稚贝运输中的存活影响,从而为稚贝运输过程中的运输方式、环境温度及运输时间的把握提供借鉴和参考。以3月龄稚贝为实验材料,运用无水干露、加水淹没及包装充氧等3种方式,分别在环境温度为5、13、21和29℃下模拟运输。每隔3 h从每组运输条件下取出1组实验贝,转移到正常养殖环境下暂养恢复,经48 h后统计其存活率。对运输时间与存活率之间进行非线性参数曲线拟合,计算每组运输条件下的致死时间(T0)、半致死时间(T0.5)及全致死时间(T1);运用双因素方差分析,Duncan氏方法比较3种运输方式及4种环境温度间的均值。结果显示:包装充氧优于其他两种运输方式,而加水淹没又优于无水干露;温度为13℃和21℃时优于其他2个环境温度,环境温度为17.60~20.05℃是稚贝运输的最佳温度。

    Abstract:

    Comparison of the survival rates of different transport modes and temperature for the Pinctada fucata juveniles was made so as to provide references for the transportation. Three-month-old P. fucata juveniles were used as experimental materials, and three methods of dry transport, water transport and oxygen transport were used to simulate transportation at temperature of 5, 13, 21 and 29℃ respectively. One group of experimental juveniles was taken from each group of transport conditions every 3 h, and transferred to a normal environment for temporary recovery, and the survival rate was calculated after 48 h. Nonlinear parameter curve fitting between transportation time and survival rate, and calculated lethal time (T0), semi-lethal time (T0.5) and total lethal time (T1) for each group of transport conditions, two-way analysis of variance were used, and the Duncan method was used to compares the average of the three modes of transport and the four temperatures. The results showed that:the survival rates of oxygen transport mode is higher than the other two transportations, and the water transport is better than dry transport. The survival rates of temperature at 13℃ and 21℃ are highter than that of the other two temperatures, and the temperature from 17.60℃ to 20.05℃ is the optimal temperature for the P. fucata juveniles transportation.
