在飞蝇钓中之所以会提出“放鱼”的概念,就是为了减少飞蝇钓爱好者对鱼类资源的冲击。事实上,如果飞蝇钓爱好者了解一些科学数据,就会知道“放鱼”对于鱼类生存的影响程度了(约为10%甚至更高)。可以用一个假设来了解这一情况,究竟是飞蝇钓爱好者一天放鱼50条对鱼类资源影响大,还是一个人留一两条鱼作为晚餐享用对鱼类资源的影响大?显然前者更有意义。在放鱼的过程中,有三点是非常重要的,这三点往往会对鱼类在被放归水中之后是否存活有着巨大的影响。 The reason why fly fishing puts forward the concept of “releasing fish” is to reduce the impact of fly fishing lovers on fish resources. In fact, if fly fishing enthusiasts know some scientific data, they know the extent to which “releasing fish” affects fish survival (about 10% or more). One hypothesis can be used to understand this situation. Is it true that fly fishing lovers have 50 fish a day affecting fish stocks, or are they leaving one or two fish for dinner as a big influence on fish resources? Obviously the former more meaningful. During the process of releasing fish, three points are very important. These three points often have a huge impact on the survival of fish after they have been released into the water.
