| 摘 要： | 于2002年4月~2003年3月研究了牛山湖翘嘴鲌(C luter alburnus)和红鳍原鲌(Cultrichthys erythropterus)的年龄组成与生长。研究结果表明,翘嘴鲌由5个年龄组组成,以2~4龄鱼为主;红鳍原鲌由3个年龄组组成,以2龄鱼为主。翘嘴鲌的平均体长和体重分别为367 mm和551 g;红鳍原鲌的平均体长和体重分别为141 mm和42 g。翘嘴鲌和红鳍原鲌的体长与体重关系式分别为W=0.00001L2.9902与W=0.000005L3.1941。牛山湖鱼类主要由适应静水生活的湖泊定居性鱼类组成,红鳍原鲌较多,而翘嘴鲌较少。 |

| Abstract: | Age and growth of Cluter alburnus and Cultrichthys erythropterus in Niushan Lake were studied.The results showed that C.alburnus had five age class and were mainly 2~4 years old.C.erythropterus had three age class and were mainly 2 years old.Average body length and body weight of C.alburnus were 367 mm and 551 g respectively.Average body length and body weight of C.erythropterus were 141 mm and 42 g respectively.The relationship between body length and body weight of C.alburnus and C.erythropterus expressed in W=0.00001 L~(2.9902) and W=0.000005 L~(3.1941) respectively.Fish stock of Niushan Lake was mainly resident fish that adapt to quiescent water.C.erythropterus was abundant and C.alburnus was scarce in Niushan Lake.The feasibility and way to increase economic and ecological benefit of lake fishery by optimizing fish community structure was discussed. |
