Data and model assumptions for an age structured production model of the Tristan lobster fishery.

An age-structured production model (ASPM) is to be developed for each of the four islands of the Tristan da Cunha group (Tristan, Inaccessible, Nightingale and Gough).The model will be sex-disaggregated as there are substantial differences in growth rates and length at age between the sexes.The model will be fit to CPUE and possibly catch-at-length data. A historic catch series developed for each island will be used. The model will run from 1949 when commercial harvesting first began. The resource will be assumed to be at pristine equilibrium at the start of 1949.

为特里斯坦达库尼亚群岛（特里斯坦、不可接近岛、夜莺岛和戈夫岛）的四个岛屿各自开发一个年龄结构生产模型（ASPM）。由于性别在生长率和年龄长度方面存在显著差异，模型将按性别进行细分。模型将根据渔获量（CPUE）和可能的渔获长度数据进行调整。将为每个岛屿开发一个历史渔获系列。模型将从1949年开始运行，这一年商业捕捞首次开始。假定在1949年初，资源处于原始平衡状态。
