Commercial Fishing Data

The primary goal of this project was to inform long-term marine protected area (MPA) monitoring efforts by gathering up-to-date socioeconomic information to illustrate historical trends, establish a post MPA baseline, and assess initial changes since MPA implementation for the commercial fishing fleet in the North Coast region of California. To accomplish this goal our research team conducted extensive community outreach and engagement in the region and conducted in-person interviewed commercial fishermen to gather post MPA baseline socioeconomic data and spatial fishing data for the year 2013. Additional to the interview data gathered, we summarized commercial fishing landings data from 1992 to 2014 obtained from the California Department of Fish and Wildlife (CDFW) to explore historical economic trends and initial changes in North Coast commercial fisheries. This data package include the commercial fishing landings data from 1992-20142 provided by California Department of Fish and Wildlife summarized to the port and region level; select summarized survey data from fishermen interviews about their fishing operations in the 2013 calendar year, and samples of the spatial data available on the post MPA (2013) and spatial change between pre MPA (2000-2009) and post MPA (2012) fishing grounds at region-fishery and port-fishery scales.本项目的核心目标是为加州北海岸海域的长期海洋保护区（Marine Protected Area, MPA）监测工作提供决策支撑：通过收集最新的社会经济数据，阐明历史发展趋势、建立MPA实施后的基线水平，并评估该区域商业捕捞船队自MPA实施以来的初步变化情况。为实现上述目标，研究团队在该区域开展了广泛的社区外联与参与工作，并对商业渔民进行了面对面访谈，以采集2013年的MPA实施后基线社会经济数据与空间捕捞数据。除上述访谈数据外，研究团队还对从加州鱼类与野生动物局（California Department of Fish and Wildlife, CDFW）获取的1992年至2014年商业捕捞上岸数据进行了汇总整理，以探究北海岸商业捕捞业的历史经济趋势与初步变化。本数据包包含以下内容：由加州鱼类与野生动物局提供的、汇总至港口与区域层面的1992-20142年商业捕捞上岸数据；经筛选汇总的渔民访谈数据（内容为受访者2013日历年的捕捞作业情况）；以及MPA实施后（2013年）的空间捕捞数据样本，还有以区域-渔业、港口-渔业为尺度的MPA实施前（2000-2009年）与实施后（2012年）捕捞场之间的空间变化数据样本。
