Pre-MPA South Coast Commercial Fisheries

These datasets are a part of Ecotrust's project entitled: Commercial and CPFV Fisheries Values and Uses project. This project is a component of the California Marine Life Protection Act Initiative that is designed to characterize the ecological and socioeconomic conditions within the MLPA Regions. These datasets are for the North Coast study region, which extends from the north at Point Conception to the south at the California/Mexico border, and consist of data collected in the summer of 2006 from fisheries mapping interviews with commercial fishermen who had landings in the California South Coast Region in the 5 years prior to collection. Results from the interviews were then combined through an aggregation process where the value each fisherman gives to their fishing grounds are weighted by their landings. Each dataset represents the spatial extent and relative value of the fishery in the years prior to MPA implementation

本数据集隶属于生态信托（Ecotrust）开展的一项命名为「商业与商业休闲渔船（CPFV）渔业价值与用途项目」的研究。该项目是加州海洋生物保护法（California Marine Life Protection Act, MLPA）倡议的组成部分，旨在全面表征MLPA区域内的生态与社会经济现状。本次数据集覆盖北海岸研究区域，其范围北起康塞普西翁角（Point Conception），南至美墨边境；数据采集于2006年夏季，通过对2006年之前5年期间在加州南海岸区域有渔获上岸记录的商业渔民开展渔业制图访谈获取。随后通过聚合流程整合访谈结果，以每位渔民的渔获上岸量为权重，对其赋予各自作业渔场的价值进行加权核算。每个数据集均可表征海洋保护区（Marine Protected Area, MPA）实施前数年的渔业空间范围与相对价值。
