| 摘要: |
| 随机从福建泉州山美水库2002 年4 月—2003 年5 月的翘嘴红鲌(Erythroculter ilishaeformis)渔获物中获取340 尾样本, 以鳞片为年龄鉴定材料, 获得年龄生长资料, 建立生长方程和Beverton-Holt 模型对山美水库翘嘴红鲌资源进行评估, 为制定合理的捕捞年龄和捕捞规格提供科学依据。结果表明, 山美水库翘嘴红鲌体重范围是0.035—4.12kg, 体长范围是15.6—73.5cm, 其中体长20.1—60.0cm 的样本占93.57%, 且为2+—3+龄。本文给出了该鱼类体长与体重的关系式、体长与鳞径的关系式以及相关的von Bertalanffy 方程。山美水库翘嘴红鲌生长拐点为10.4 龄, 山美水库现有资源量为10.164t, 合理开捕年龄为6 龄。 |

| Abstract: |
| 340 individuals of Erythroculter ilishaeformis Bleeker were collected in Shanmei Reservoir during April, 2002 to May, 2003. After studying the growth characteristics, the growth equation and Beverton-Holt model were established to evaluate the Culter alburnus resources of Shanmei Reservoir. The results shown that the range of body weight and body length were 0.035—4.12kg and 15.6—73.5cm, respectively. Samples of the body length of 20.1—60.0cm accounted for 93.57%, which was 2+—3+ages. The relationship between body weight and length was W = 2.5034×10-5L2.825 (r=0.999). Body length and scale size relationship was L = 10.489 + 7.534R (r=0.997). The Von Bertalanffy equation are Lt = 120.5981×[1－e–0.0913(t+1.09)] and Wt = 21.9368×[1－e–0.0913(t+1.09) ]2.825, which the growth inflection point was 10.4 ages. By using length cohort analysis and B—H model, the resource capacity (B) was 10.164t, and the reasonably catchable age (tc) was 6 age. |
