The five categories (developing, fully exploited, overexploited, collapsed and recovering of a previously collapsed stock) of stock exploitation according to the catch-based method, which is based on the relationship between the catches (C_Y) of a given year (Y_C) compared to the year (Y_Cmax) of historical maximum catch (C_MAX).

The five categories (developing, fully exploited, overexploited, collapsed and recovering of a previously collapsed stock) of stock exploitation according to the catch-based method, which is based on the relationship between the catches (CY) of a given year (YC) compared to the year (YCmax) of historical maximum catch (CMAX).本数据集涵盖基于渔获量法（catch-based method）划分的渔业种群开发状态的五大类别：开发中（developing）、充分开发（fully exploited）、过度开发（overexploited）、崩溃型（collapsed）以及此前崩溃种群的恢复型（recovering of a previously collapsed stock）。该评估方法以某指定年份（记为YC）的渔获量（Catch, CY）与历史最大渔获量（CMAX）对应的年份（记为YCmax）之间的关联关系为核心依据。
