摘要
本实验对 1 0个批次 ,总数为 1 90 47尾的不同规格和产地的牙鲆鱼苗长途运输效果进行了研究 .结果表明 ,规格为 9～ 1 2cm的鱼苗 ,在水温 6～ 1 2℃ ,运输时间为35～ 50h ,采用空运和低温活水车运输 ,运输死亡数为 6 6 4尾 ,死亡率为 3.39% ,低温活水车短途运输是可行的 ,尽管长途车运方式成本较低 ,但由于应激强度较大 ,对鱼苗的生产性能影响较为严重 ,驯养 1 0d累计死亡率最高达 1 8.1 7% ,这种模式不可取 .低温 ( 6℃ )、小规格 ( 9cm)的空运较适合牙鲆鱼苗长途运输 .此外 ,本文还就运输应激反应、预防措施和药物防治进行详细的讨论 .
This experiment was conducted to study the long-distance transports of Paralichthys olivaceus fries with different sizes and producing place for ten batches and 19 047 fishes. The results showed that about 664 fries with body length of 9～12cm died during transport with 3.39% mortality rate under the temperature 6～12℃, 35～50h transport time by airplane and vehicle with flowing water. From these results, it concluded that short distance transport ation by vehicle with flowing water in low temperature was feasible. It is not suit for long-distance transport of P.olivaceas fries with vehicle, though it's cost maybe lower ,an influence of strong transportation stress on its productive performance was very obvious, with the highest cumulative mortality of P.olivaceus fries cultivated for 10 days arrived at 18.7%. And it's suit for long-distance transport of P.olivaceus fries under the condition of low temperature (6℃) and small sizes (9cm) by airplane. In addition, this paper also discussed on transportation stress,defend measure and medicament cure in detail.
