根据1984—1986年在湖北省网湖进行渔业资源调查的资料,应用Von Bertalanffy生长方程描述该湖鲫鱼的生长模式,同时按照Joneo体长股分析模型和Thompson-Bell体长预测模型分别推算鲫鱼资源量和不同捕捞强度下资源量和渔获量的理论值,并求得最大持续渔获量。据此,对该湖鲫鱼资源的合理开发和利用进行了分析和讨论,并提出渔业对策。
According to the data of investigation of fishery resources in Hubei Net Lake from 1984 to 1986, the growth pattern of Carassius auratus was described by Von Bertalanffy growth equation. The crucian carp resources were estimated according to Joneo long-legged analysis model and Thompson-Bell body length prediction model Quantity and different fishing intensity of resources and catch the theoretical value, and obtain the maximum sustained catch. Accordingly, the reasonable exploitation and utilization of the crucian carp resources in the lake were analyzed and discussed, and fishery measures were put forward.
