Collection locations, dates, and weight and length measurements of individuals of three fish species from the Matagorda Bay region of Texas in the northwestern Gulf of Mexico from 2021 to 2023

This dataset describes the collection locations of individuals of three fish species (Red Drum Sciaenops ocellatus, Southern Flounder Paralichthys lethostigma, and Atlantic Croaker Micropogonias undulatus) in the Matagorda Bay region of Texas in the northwestern Gulf of Mexico. Fish carcasses were obtained from anglers at boat docks, fish cleaning stations, or other locations in the region. Fish were also obtained from bait shops where the proprietors verified the fish were sourced from the Matagorda Bay study region. These fish will be dissected to subsample muscle tissue, eye lenses, and otoliths for chemical analysis to reconstruct environmental histories (trace element proxies for hypoxia, salinity, and other parameters), mercury concentrations, and stable isotopes to reconstruct food web interactions.本数据集记录了墨西哥湾西北部得克萨斯州马塔哥达湾（Matagorda Bay）区域内3种鱼类——红鼓（Sciaenops ocellatus）、南方鲽（Paralichthys lethostigma）、大西洋叫姑鱼（Micropogonias undulatus）——的个体采样点位信息。实验用鱼体样本采集自该区域内船坞、鱼类处理站及其他点位的垂钓者手中；另有部分样本来源于渔具店，经店主确认这些鱼类均采自马塔哥达湾研究区域。后续将对这些样本进行解剖，分取肌肉组织、眼晶状体和耳石（otoliths）开展化学分析，以重建鱼类的生存环境历史（包括用以指示低氧、盐度等环境参数的微量元素替代指标）、汞含量，并通过稳定同位素分析还原其所在食物网的相互作用关系。
