黄河小浪底水库长春鳊(Parabramis pekinensis)生长特征研究
|
摘要
黄河小浪底水库有着独特的河流生态系统和珍贵的水生生物资源,小浪底水利枢纽是治理开发黄河的关键性工程,对经济提升及生态保护有着重要的作用。根据2013年小浪底水库长春鳊的生物学调查及分析,求得长春鳊的体长与体重的关系式、生长方程、各项生长参数以及生长特征的变化情况,估算出小浪底水库长春鳊的资源量的对策。结果表明:小浪底水库长春鳊的体长生长方程为Lt=425×[1-e-0.46(t+0.286)],体重生长方程为Wt=1650.922×[1-e-0.46(t+0.286)]2.945,体重生长的拐点年龄为2.06龄,群体临界年龄为2.46龄,资源生物量为8669.38t。
Xiaolangdi reservoir of the yellow river has a unique river ecosystem and precious aquatic biological re-sources.Xiaolangdi water conservancy project is a key project for harnessing and developing the Yellow River,whichplays an important role in economic upgrading and ecological protection.Based on the biological investigation andanalysis of Parabramis pekinensis in Xiaolangdi reservoir in 2013,the relationship between body length and bodyweight,growth equation,growth parameters and growth characteristics of Parabramis pekinensis were obtained.The re-source amount of Parabramis pekinensis in Xiaolangdi reservoir was estimated,and suggestions for sustainable devel-opment and rational utilization of resources were put forward.The result indicated that the growth equation of lengthand weight are respectively Lt=425×[1-e-0.46(t+0.286)]and Wt=1650.922×[1-e-0.46(t+0.286)]2.945,and the weight growth in-flection age and critical age of Parabramis pekinensis 2.06 and 2.46.The biomass in Hun River of Shenyang is about73.56 t.
