雪野水库位于山东省的莱芜市,在全省大型水库中位居第三,大量网箱养鱼,水较肥。水库中鲤、鲫、草、鲢、黑、翘嘴我鲌、鳜等适宜垂钓的鱼种很多,鱼情稳定、上鱼率高,是垂钓者比较理想的选择地。 但这个水库有个明显怪异的特点,那就是盛夏时节,夜钓效果不佳。常是白天鱼不断咬钩,晚上则对香饵不理睬。究竟是何原因?学生物的我,带着这些疑问,跑图书馆,上网查找资料,觉得问题渐渐地明晰起来:是水的溶氧量成为影响鱼类活动的主要因素。 Located in Laiwu City, Shandong Province, Xueye Reservoir is the third largest reservoir in the province with a large amount of cage fish and more water. Reservoir carp, crucian carp, grass, silver carp, black, Alice mouth I 鲌, 鳜 such as suitable for fishing many species, stable fish, the fish rate is ideal for anglers to choose. But this reservoir has a distinctly weird feature, that is, summer season, night fishing ineffective. Often the fish bites constantly during the day and ignores it at night. What exactly is the reason? Students, I, with these questions, run the library, find information online, I feel the problem gradually clear: the dissolved oxygen of water has become a major factor affecting fish activity.
