垂钓实践证明,一旦钩上的鱼脱钩逃跑后,一般情况下,在同一窝子里短时间内不再有鱼来咬钩。对这种现象的解释,有人认为脱钩受伤的鱼从皮肤中分泌一种叫“警戒素”的微量物质散布于水中,其它同种或异种鱼类个体接受“警戒素”的刺激后产生“警戒反应”而向别处逃避。这种解释正不正确?笔者做过一些实验与观察。现将结果谈出来,就教于广大垂钓爱好者。 Fishing practices have proved that once the fish hooked off the hook escape, under normal circumstances, in the same nest no fish to bite a short time. The interpretation of this phenomenon, some people think that decoupling injured fish secrete from the skin a trace amount of material called “sclerostin” scattered in the water, other species of the same or different species of fish to accept “sodatorin” stimulus “warning Reaction ”and to escape elsewhere. This explanation is incorrect? I made some experiments and observations. Now talk about the results, to teach the majority of fishing enthusiasts.
