Abstract

The proposed generalized model of recruitment formation in exploited fish populations provides a full description of the class of “stock–recruitment” relationships based on the concept of the density-dependent regulation of population dynamics. The results of an analysis of a deterministic model version that includes five control parameters are presented. The proposed unified model, being derived ab initio, allows the quantitative comparison (at the level of parameter values) of qualitatively different descriptions of recruitment processes based on alternative hypotheses of the mechanisms and factors of the processes in question. The generality of the model formulation enables the transition from the deterministic version to a stochastic one, which may include, at the same time, the effects of environmental factors.

回到人口管制问题：鱼类开发种群的普遍征兵形成模型

摘要

拟议的利用鱼类种群招募形成的通用模型基于种群动态的密度依赖调节概念，全面描述了“种群-征募”关系类别。给出了包含五个控制参数的确定性模型版本的分析结果。从头开始推导的拟议统一模型允许基于所讨论过程的机制和因素的替代假设，对招聘过程的定性不同描述进行定量比较（在参数值的水平上）。模型公式的通用性使它可以从确定性版本过渡到随机版本，这可能同时包括环境因素的影响。
