    摘要:

    以在山东地区开展中国大鲵(Andrias davidianus)大规模人工养殖为目标,开展了地下室微流水人工养殖的试验研究。试验对大鲵养殖场地建设、水质、饲料和病害防治的管理等方面进行了分析,设置1龄和3龄2个年龄组,根据生物学测量的结果进行中国大鲵生长情况分析。结果显示:经过2年人工养殖,1龄大鲵和3龄大鲵的平均体重增长率分别达到6874.5%和167.5%,平均体长增长率分别达到254.3%和50.5%;体重增长速度随养殖时间增加呈现“慢-快-慢”特点,体长增长速度随养殖时间增加逐渐降低;特定生长率呈现先高后低,随着时间变化显著降低的特点;生长拐点为3.38,说明3~4龄是大鲵体重增加的关键时期。地下室微流水人工养殖中国大鲵具有体重、体长增长快速,生长拐点出现较早,养殖周期缩短的优点,该研究可为大规模开展大鲵人工养殖提供参考。

    Abstract:

    In order to achieve the object of Chinese giant salamander (Andrias davidianus) large-scale cultivation in Shandong province area, an experiment on cultivation in basement with gentle flowing water was carried out. The experiment, set 2 age groups of 1 and 3 years old, analyzed many aspects of culture field construction, management of water quality, feed and disease prevention and treatment, and growth condition of Chinese giant salamander based on the result of biological measure. The results show that:After two years,the Chinese giant salamander′s growth rate of average weight reached 6874.5% and 167.5% and average length reached 254.3%和50.5% at 1 and 3 years old respectively; The growth rate of weight taken on a character of “slow-fast-slow”, and of body length reduced gradually with increased culture time; Specific growth rate appeared a rule of high before and low behind, significantly reduced in all follow with culture time; Growth inflexion was 3.38, indicated that 3~4 years old is the critical period of weight growth. In all, the Chinese giant salamander cultivated in basement with gentle flowing water,has advantages in growth rate of body weight and length faster, growth inflexion come forth earlier, cultivation cycle shorter, the study can provide reference for carrying out large-scale Chinese giant salamander culture in Shandong area.
