沈阳浑河鳑鲏鱼的生长特征与资源合理利用
|
摘要
为了制定沈阳浑河鳑鲏鱼的开捕策略,根据2016年沈阳浑河鳑鲏鱼的生物学调查数据,分析了鳑鲏鱼的体质量组成和体长组成,求解出了鳑鲏鱼的体长体质量关系式和体长、体质量生长方程,计算了体质量生长的拐点年龄、临界年龄和总瞬时死亡率,估算了沈阳浑河鳑鲏鱼的资源数量~([1-2])。结果表明:沈阳浑河鳑鲏鱼的体长生长方程为L_t=110.25×(1-e~((-0.49(t+0.38831)))),体质量生长方程为Wt=27.63173×(1-e(~(t+0.38831)))~(2.7117),体质量生长的拐点年龄为1.65龄,群体临界年龄是2.14龄,沈阳浑河鳑鲏鱼的资源生物量为73.56t。沈阳浑河鳑鲏鱼的开捕体长为69.6~78.3mm,开捕体质量为7.9~10.9g。
In order to formulate Rhodeus catchable size and total allowable catch in Hun River of Shenyang,on basisof investigative data,by analyzing the length-weight formula,body length and weight growth equation,and instanta-neous mortality rate,to calculate weight growth inflexion age,the critical age and the biomass of Rhodeus in HunRiver of Shenyang.The result indicated that the growth equation of length and weight are respectively L_t=110.25×(1-e~((-0.49(t+0.38831))))and Wt=27.63173×(1-e(~(t+0.38831)))~(2.7117),and the weight growth inflection age and critical age of Rhodeus are1.65 and 2.14. The biomass in Hun River of Shenyang is about 73.56 t.To Rhodeus stock in Hun River ofShenyang,the catchable length is about 69.6~78.3mm,and catchable weight is about 7.9~10.9g.
