TPWD HARC Texas Coastal Fisheries, Corpus Christi Bay Gill Net

The Texas Parks and Wildlife Department (TPWD) utilizes several sampling gears for fisheries-independent monitoring of finfish and shellfish communities. They include bag seines, trawls, gill nets and oyster dredges. TPWD uses multiple gears in a random sampling protocol, and they identify (to the lowest taxonomic unit possible) and count everything that they collect. This dataset contains gill net data collected for the Corpus Christi bay system in Texas from 1976 to 2008. Collected data also included spatial and temporal information describing the sample location and time, collection gear information, hydrological data (e.g. dissolved oxygen, water temperature, and salinity), weather conditions, species caught, and number of each species captured. Houston Advanced Research Center (HARC) calculated the relative abundance data, calculated as the catch of a particular species in a sample divided by the total number of animals captured in that sample. Absence data was recorded for species on the TPWD species sampling lists that were not captured during sampling.

得克萨斯公园与野生动物部门（Texas Parks and Wildlife Department, TPWD）采用多种采样渔具开展鱼类及贝类群落的渔业独立监测，所用渔具包括袋围网、拖网、刺网与牡蛎采捕拖网。TPWD通过随机采样方案搭配多渔具组合开展工作，并对采集到的所有样本尽可能鉴定至最低分类单元，同时完成个体计数。本数据集收录了1976年至2008年间，得克萨斯州科珀斯克里斯蒂湾流域的刺网采样数据。采集数据涵盖以下内容：描述采样位置与时间的时空信息、采样渔具信息、水文数据（如溶解氧、水温与盐度）、天气状况、捕获物种及各物种的捕获数量。休斯顿高等研究中心（Houston Advanced Research Center, HARC）计算了相对丰度数据：其定义为某一样本中特定物种的捕获量除以该样本内捕获的总动物个体数。针对TPWD物种采样名录内的物种，若采样期间未捕获到该物种，则记录其缺失数据。
