North Atlantic fish stock recruitment, spawning stock biomass, weight at age and numbers at age

AbstractThe correct prediction of the shape and strength of density-dependence in productivity is key to predicting future stock development and providing the best possible long-term fisheries management advice. We identify unbiased estimators of the relationship between somatic growth, recruitment and density, and applied these to 80 stocks in the Northeast Atlantic. The data used for the analysis is published here.MethodsThe data here have been used in an analysis of density dependent growth and recruitment currently submitted to Fish and Fisheries. The data set includes data on 25 species divided into 80 stocks. Usage NotesN1= number at age 1 and so forth, W1= weight at age 1 and so forth. -1 denotes missing value.

摘要
准确预测生产力中密度依赖（density-dependence）关系的形式与强度，是预判渔业种群未来发展态势、提供最优长期渔业管理建议的关键所在。本研究确定了个体生长（somatic growth）、种群补充量（recruitment）与密度之间关系的无偏估计量，并将其应用于东北大西洋的80个渔业种群。本分析所用数据集已在此处发布。

方法
本数据集已被用于一项关于密度依赖型生长与种群补充量的分析，该分析目前已投稿至《Fish and Fisheries》期刊。本数据集涵盖25个物种的相关数据，共分为80个渔业种群。

使用说明
N1代表1龄个体数量，其余以此类推；W1代表1龄个体体重，其余以此类推。-1表示缺失值（missing value）。
