读过2005年第八期《(?)鲦出水只有3秒钟的生命》一文，感到新 奇，于是请教上海水产大学几位教授，他们与我有同感。因此 查阅有关资料，但关于(?)鲦离水后的存活时间确实没有资料。不过 从一些实际情况我们了解到，(?)鲦离水后的寿命不仅局限于3秒钟 内。上海郊区每年冬季干塘时，历时1个小时，甚至更长的时间，(?) 鲦仍在泥上或在车干水的水草中挣扎。 我们已经知道，鱼是靠鱼鳃的呼吸来维持生命的，当鱼鳃在水 中时，每个鳃小片的上下表面都和水接触，鳃腔内的水始终处于流 动状态，从而呼吸得以正常进行。但当鱼离开水后，鳃小叶粘叠在一 起，无法和外界接触，更由于在空气中干燥失水和表面的黏液凝结， 很快就无法交换气体，但鲤鱼、鲫鱼等离水后(尤其在冬季)，只要用 Read the eighth issue of 2005 (“? 鲦 water only three seconds of life,” a text, feel novel, so consult several professors Shanghai Fisheries University, they agree with me. Therefore, access to relevant information, but there is no information on (?) 存 survival time after leaving the water. However, we have learned from some actual situations that (?) 鲦 life after leaving the water is not limited to 3 seconds. Every year in Shanghai’s suburbs dry ponds, which lasted 1 hour or longer, (?) 鲦 is still mud or in the car dry water plants struggling. We already know that fish rely on the gills of fish for their life. When the fish gills in the water, the upper and lower surfaces of each gill piece are in contact with the water, and the water in the gill cavity is always in a flowing state so that the breathing can proceed normally . However, when the fish leaves the water, the gill leaflets stick together and can not contact with the outside world. Because of the dehydration in the air and the coagulation of the mucus on the surface, the gills will soon be unable to exchange gas. However, after carp, In winter), just use
