日本的几位鱼类专家做过有趣的试验。在一个放养了罗非鱼、鲤鱼、草鱼等十多种鱼的水池边,他们先用鱼钩把水池里的鱼尽可能多地钓出,然后加上标记放回水池,接着再次垂钓……如此重复三次后,他们发现第一次就上钩的鱼儿中,第二、三次继续上钩的高达百分之六十。这意味着,鱼儿并不会“吃一堑,长一智”。看来鱼儿是否易上钩与其本身的“素质”息息相关。进一步研究显示,易上钩的鱼儿往往食欲旺盛,反应灵敏,体力充沛,一见食物便奋不顾 Several fish experts in Japan have done interesting experiments. At a pool of more than ten kinds of fish, such as tilapia, carp and grass carp, they first fish as many as possible from the pool with hooks, then mark it back into the pool and then go fishing again ... After repeating three times, they found that the fish caught the first time, the second, three times continue to hook as high as 60%. This means that the fish do not “eat a cut, grow smart.” It seems that fish are easily hooked with its own “quality” is closely related. Further research shows that the fish that are easy to hook are often appetite, responsive and energetic, regardless of the food they see
