| 摘 要： | 2010年4~11月,在沱江的资中-隆昌段采集宽体华鳅(Sinibotia reevesae)573尾,研究了其年龄结构和生长特性。结果表明,微耳石厚度适中,易于磨片,且磨片后轮纹清晰,能准确反映宽体华鳅的年龄情况。收集到的沱江宽体华鳅体长主要分布在80~100 mm,占总数的67.54%;体重主要分布在8~20 g,占总数的69.11%;年龄由2~6龄组成,以3~4龄为主,占85.91%;种群雌雄性比为1︰1.11。体长(L,单位mm)和体重(W,单位g)关系,雌雄群体间无明显差异(P0.05),其表达式为W=5×10﹣6L3.286 8(n=573,R2=0.820 2),为近等速生长类型。von Bertalanffy生长方程为Lt=128.721﹣e﹣0.197 4(t+1.66)]和Wt=42.951﹣e﹣0.197 4(t+1.66)]3.286 8。体长生长速度和加速度方程为d L/dt=25.413 3 e﹣0.197 4(t+1.66)和d2L/dt 2=﹣5.015 8 e﹣0.197 4(t+1.66),体重生长速度和加速度方程为d W/dt=27.866 6 e﹣0.197 4(t+1.66)1﹣e﹣0.197 4(t+1.66)]2.286 8和d2W/dt2=5.500 9 e﹣0.197 4(t+1.66)1﹣e﹣0.197 4(t+1.66)]1.286 8×3.286 8 e﹣0.197 4(t+1.66)﹣1]。生长拐点年龄为4.37,此时的体长和体重分别为89.46 mm和12.99 g。分析显示,沱江资中-隆昌段宽体华鳅自然种群资源未遭到严重破坏,但合理开发水电资源和选择合适的渔具、渔法是进行其资源保护的最有效措施。
