SEFSC CAGES Alabama Fish Length Data with CPUE

The CAGES program (Comparative Assessment of Gulf Estuarine Systems) is designed to examine the differences between estuarine ecosystems and investigate why some are more productive than others. The program focuses on estuarine areas important to commercial fisheries and includes data on commercial finfish and invertebrate species, as well as other species commonly captured in trawl sampling. This Louisiana dataset is a subset of the CAGES Relational Database which is a compilation of fishery-independent data contributed by natural resource agencies of the Gulf States (Texas, Louisiana, Mississippi, Alabama, and Florida). This data set includes data from trawls collected by the Alabama Department of Conservation and Natural Resources (ADCNR) and Gulf Coast Research Laboratory (GCRL), as well as associated hydrographic data. Trawl data were used to calculate CPUE (catch per unit effort) at each station for the years 1981 through 2007.

CAGES项目（Comparative Assessment of Gulf Estuarine Systems，即海湾河口系统对比评估）旨在探究河口生态系统之间的差异，并解析部分生态系统生产力更高的原因。该项目聚焦于对商业渔业具有重要意义的河口区域，涵盖商业鳍鱼类、无脊椎动物物种，以及拖网采样中常见捕获的其他物种的相关数据。本路易斯安那州数据集是CAGES关系数据库的一个子集，该数据库汇集了墨西哥湾沿岸各州（得克萨斯州、路易斯安那州、密西西比州、阿拉巴马州及佛罗里达州）自然资源机构提供的渔业独立数据。本数据集包含由阿拉巴马州保护与自然资源部（Alabama Department of Conservation and Natural Resources, ADCNR）及墨西哥湾沿岸研究实验室（Gulf Coast Research Laboratory, GCRL）采集的拖网数据，以及相关的水文数据。研究人员以1981年至2007年各采样站位的拖网数据为基础，计算得到各站位的单位捕捞努力量渔获量（catch per unit effort, CPUE）。
