鮰鱼是海鱼还是河鱼

　　鮰鱼不是海鱼也不是河鱼，是湖鱼。鮰鱼是一种底栖鱼类，通常在水流缓慢的深水河湾生活。这种鱼白天会潜伏在水底，到了晚上才会觅食，一般在水体的中下层活动，冬季会游到更深的地方。它主要以水生昆虫、甲壳类以及小鱼为食，在中国的分布比较广泛，其中常见水系最为常见。

　　鮰鱼生活习性：

　　长吻鮠为底层鱼类。常在水流较缓、水深且石块多的河湾水域里生活。白天多潜伏于水底或石缝内，夜间外出寻食。觅食时也在水体的中、下层活动；冬季多在干流深水处多砾石的夹缝中越冬。主要以水生昆虫及其幼虫、甲壳类、小型软体动物和小型鱼类为食。长吻鮠属温水性鱼类，生存温度为0～38℃，生长适温为15～30℃，pH范围6.5～9.0，最适pH7.0～8.4，不耐低氧，当池塘水质溶解氧低至2.5毫克/升时，则会浮头。长吻鮠营底栖生活，喜集群、畏光。

During the day, it lurks on the bottom of the water or in rock crevices, and goes out to hunt for food at night. It is also active in the middle and lower layers of the water body when foraging; in winter, it mostly spends the winter in the gravel crevices in the deep water of the mainstream. Feeds mainly on aquatic insects and their larvae, crustaceans, small mollusks and small fish. It is a warm-water fish, with a survival temperature of 0 to 38 °C, a suitable growth temperature of 15 to 30 °C, a pH range of 6.5 to 9.0, an optimum pH of 7.0 to 8.4, and is not resistant to hypoxia. As low as 2.5 mg/L, the head floats. Long-nosed scorpion camps benthic life, likes flocks, photophobia.
