通过对长白山区主要冷水水域调查,得知的冷水鱼为5目7科11种,主要分布于鸭绿江上游及支流中,栖息的最适温度为12～18℃,繁殖期水温一般不超过13℃,食性多属于肉食性,水质要求清澈无污染。调查研究发现长白山区冷水鱼的种类有趋于减少的趋势,种群数量也是越来越少,甚至有的种类已成为珍稀或濒危物种。
According to the investigation of the main cold waters in Changbai Mountains, the 5 species, 7 families and 11 species of cold water fish are found, which are mainly distributed in the upper reaches and tributaries of the Yalu River. The optimum temperature for habitat is 12 ~ 18 ℃ and the water temperature during breeding is not more than 13 ℃ Most of the food is carnivorous, water quality requirements clear and pollution-free. The survey found that the species of cold-water fish in Changbai Mountain tends to decrease, the population is also less and less, and even some species have become rare or endangered species.
