Water energy resource exploitation research in heilongjiang province there are four water systems in heilongjiang province , including heilongjiang river , songhuajiang river , wusuli river and shuifenhe river , which are abundant in waterpower resource 黑龙江省境内有黑龙江、松花江、乌苏里江和绥芬河四大水系，具有较丰富的水能资源。
The ratio of tail length / tail width is the same as nikerlcki and different with wuxianwen ( 1964 ) and zhangjuemin ( 1995 ) . the fish captured in wusuli river , but nikerlcki ' s from xingkai lake , and wuxianwen ' s from changjiang river 58 ；第5年比第4年增重100 。黑龙江妨的生长进入第4年时，体长基本不生长，体高由原来为体长的40增加到为体长的48 。
The wusuli river group has its stationery tour route , the spawning population wing up heilongjiang river and swims into wusuli river in early may when ice has melt , reproduces during mid june to july in middle part of wusuli river 乌苏里江种群在乌苏里江有较稳定的洄游路线，产卵群体自5月初解冻后，沿黑龙江上溯，进入乌苏里江并沿江上溯， 6月中旬至7月初在乌苏里江中游产卵。
The study analyses results of former schoiars made , carried out convey along main patch and correlate lake ; made experiments of catching and means , and captured from qindeli in middle river of heilongjiang to raohe of wusuli river ; made biological analysis of the captured fish ; finished the artificial fertilization . the results of the experiment below : 1 本研究综合分析以前学者对黑龙江鲂研究的结果，在重点江段和湖泊进行了资源调查；设计了采捕设备和方法，在黑龙江中游勤得利至抚远江段和乌苏里江饶河江段进行采捕；对采捕到的黑龙江鲂进行生物学研究；并进行了黑龙江鲂的人工繁殖。
