The data were sampled in Sabine Lake, Galveston Bay, Matagorda Bay, San Antonio Bay, Aransas Bay, Corpus Christi Bay, the upper Laguna Madre, and the lower Laguna Madre from January 1982 to December 2016 (except in Sabine Lake, where sampling begun in January 1986). The surveys were conducted bi-weekly using bag seines (18.3 m long and 1.8 m deep with 19 mm stretched nylon mesh in wings and 13 mm stretched mesh in the bag), which were deployed along the shoreline. Bag seines were deployed multiple times during the first and second halves of the month in every bay system. The location of each sample was determined by randomly selecting one station from a predefined sampling universe and, once in the field, selecting a section of available shoreline within that station. At the selected sampling location, the bag seine was extended 12.2 m perpendicularly to the shoreline, then pulled parallel to the shoreline over 15.5 m. The offshore end was then retrieved to shore while keeping the onshore end stationary and maintaining the full extent (12.2 m) of the bag seine using a limit line. Organisms greater than 5 mm in total length were identified to the lowest taxonomic level.\u00a0 Further details of sampling protocols are described in the Marine Resource Monitoring Operations Manual\u00a0(PDF).\u00a0

Note:\u00a0All station_id numbers\u00a0are included at least once in this dataset (e.g.\u00a0some organisms were observed at every station/sampling event).
Vertebrates and invertebrates caught with bag seine in Sabine Lake, Galveston Bay, Matagorda Bay, San Antonio Bay, Aransas Bay, Corpus Christi Bay, Upper Laguna Madre, and Lower Laguna Madre. Data were collected monthly from 1982 to 2016 (except in Sabine Lake sampling begun in 1986).\u00a0
BCO-DMO Processing:
\n- concatenated 1986-200 data with 2001-2016 from the two separate spreadsheets in file \"TPWD Bag seine 82-16.xlsx\";
\n- modified column names in species code list file, \"TPWD Species Code.xlsx\" (replaced spaces with underscores and removed parentheses);
\n- joined the bag seine data to the species code list based on species_code field;
\n-\u00a0joined the bag seine data to the station\u00a0list in file \"TPWD Station Data 82-16.xlsx\" based on the station_id (hydro_id) columns, retaining\u00a0the Latitude and Longitude columns from the station file.
