摘　　要：本研究以大黄鱼为试验对象,采用"初绑"、"喂水"、"绑水"的传统技术将大黄鱼弯成一个"弓"形,分析不同弓鱼位置、弓鱼方向、"喂水"过程等因素对大黄鱼存活时间和存活率的影响,旨在评估传统"弓鱼"技术在大黄鱼活体运输上的效果。该研究结果表明,经"弓鱼"技术处理后在离水条件下大黄鱼的存活时间可达2 h以上,比不做任何处理的存活时间延长4倍;穿过鱼嘴和鳃盖的捆绑方式比传统的穿鼻孔方式存活率高;"喂水"过程的有效时间是1 h;不同的"弓鱼"方向可能是当地渔民的一个习惯,对存活时间和存活率无明显影响。由此可知,传统"弓鱼"技术对大黄鱼的活体运输具有一定效果,但具体的细节还需进一步优化。Using large yellow croaker(Larimichthys crocea)as the experimental subject,this study adopted the traditional technology of“initial tying”,“water feeding”and“water binding”to bend the large yellow croaker into a bow shape,and analyzed the effects of different fixed position,bundling direction,and“water feeding”process on the survival time and survival rate.The purpose of this study was to evaluate the effect of the“Bowing fish”technology on the living transportation of large yellow croaker.The results indicated that the survival time for large yellow croaker treated with“Bowing fish”technology under waterless conditions surpassed 2 h,which was four times longer than that without any treatment.The new penetrating method(fish mouth and lid)had a higher survival rate than the traditional penetrating method(nostril).The effective time of the“feeding water”process was 1 h.The different bundling direction was only a habitual for fishermen,and there was no significant effect on the survival time and survival rate.These findings indicated that the traditional“Bowing fish”method had a certain effect on the living transportation of large yellow croaker,but the specific details needed to be further optimized.
