摘要:

实际生产过程中克氏原螯虾(又称小龙虾,Procambarus clarkii)需经过长时间运输,运输苗种成活率直接影响到养殖户的经济效益。为比较各种运输方式的死亡率,重点关注虾蟹混养“兴化模式”中定量放养抱籽虾环节,通过模拟运输实验研究不同运输方式:覆盖青苔、氧气包和不同运输时间:1、2、3 h对苗种死亡率的影响。结果表明相比带水运输,抱籽虾覆盖青苔运输1、2、3 h后死亡率分别降低30.56%、27.11%、16.00%。小规格虾苗运输过程中,使用氧气包运输较覆盖青苔运输1、2、3 h后死亡率分别降低76.99%、70.77%、72.16%。中等规格虾苗运输过程中,覆盖青苔运输较蟹苗箱运输3、6 h后死亡率分别降低13.43%、9.08%。通过该实验,养殖户可以根据需求选择合理的运输方式。

Abstract:

In the production process, Procambarus clarkii often has to go through a long transportation process, and the survival rate of the larvae directly affects the economic benefits of farmers. In order to compare the crayfish mortality under various transportation modes, particularly the quantitative stocking of crayfish in the ‘Xinghua Mode’ of shrimp-crab polyculture, the effects of different transportation modes (moss-covered and oxygen bag) and different transportation time (1, 2 and 3 h) on the larvae mortality were studied through simulated transportation experiments. The results showed that compared with water transportation, the mortality of crayfish larvae covered with moss for 1, 2 and 3 h decreased by 30.56%, 27.11% and 16.00%, respectively. In transporting small-sized crayfish larvae, the mortality of oxygen bag transport for 1, 2 and 3 h was 76.99%, 70.77% and 72.16% lower than that of moss-covered transport. During the transportation of medium-sized crayfish larvae, the mortality of moss-covered transport was 13.43% and 9.08% lower than that of crab-box transport after 3 and 6 h, respectively. Farmers can choose a reasonable mode of the transportation of crayfish larvae according to the demand.
