| ２００７年４月至２００８年４月在鲇鱼山水库采集翘嘴!（Ｃｕｌｔｅｒａｌｂｕｒｎｕｓ）样本８８５尾，对其种群进行了研究，建立了Ｂｅｖｅｒｔｏｎ－Ｈｏｌｔ种群管理模型。在目前开捕年龄ｔｃ＝２龄、自然死亡系数Ｍ＝０．４６５４、捕捞死亡系数Ｆ＝０.５４５、生长系数ｋ＝０．２３３１的情况下，鲇鱼山水库翘嘴!渔获物的平均体长为２９．９１ｃｍ，平均体重为２７８．７６ｇ，平均年龄为２．０５龄；单位补充渔获量（ＹＷ／Ｒ）为４６７．２８ｇ／尾。建议将鲇鱼山水库翘嘴!的捕捞年龄提高到３龄，有效地保护性成熟个体，提高种群补充数量，以目前捕捞强度下渔获量达到最大值，获得最大的经济效益。 |
| 英文摘要: |
| Collected 885 individuals of Culter alburnus from Nianyushan reservoir during April，2007 to April 2008. We studied the population management of Culter alburnus Basilewsky and built Beverton-Holt model. The study provided the scientific bases to make rational capture age and standard. The B-H model was built for population management. When the tc was 2, M is 0. 4654，F was 0. 5485 and k was 0. 2331，the average body length Ly was 29.91 cm，the average body weight wy was 278.76g and the average age T, was 2. 05a. The yield per unit cruitment was 467.28 g/ind. We suggest the age of Culter alburnus Basilewsky in Nianyushan reservoir must becreased to 3，so that the mature population can capture intensity the capture wei8ht arrive at thebe protected and the population size can be recriut better. In this capture intensity the capture weight arrive at the max, so we can get the most economy benefit. |
