Online_Linkage: http://www.galvestonlab.sefsc.noaa.gov/stories/2013/ecology/index.html Description: Abstract: 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 Texas 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 Coastal Fisheries Division of the Texas Parks and Wildlife Department (TPWD), as well as associated hydrographic data. Trawl data were used to calculate CPUE (catch per unit effort) data for 26 target species at each sampling site, measured in number of organisms per hectare. Data presented here show the mean CPUE at each TPWD station for the years 1982 through 2005. Purpose: The purpose of CAGES is to compile the fishery independent data from five Gulf States into a database to more easily compare the fisheries across the US Gulf of Mexico coast. This dataset includes data collected from Texas only. The CAGES database is intended for scientific research only.

Lineage: Process_Step: Process_Description: The Texas Parks and Wildlife Department (TPWD) Coastal Fisheries Division has used 6.1-m trawls to assess estuarine fishery-related resources via systematic fishery-independent sampling of its estuaries beginning in the 1960's. Since 1982, monthly sampling by trawling following a stratified cluster design with random site selections has been conducted in Texas estuaries. Galveston Bay, Matagorda Bay, San Antonio Bay, Aransas Bay, and Corpus Christi Bay were stratified into two equal-area zones for sampling to ensure good spatial distribution of samples in these larger estuarine systems; Sabine Lake, East Matagorda Bay, Upper Laguna Madre, and Lower Laguna Madre only had one zone. Each zone was divided into grids of one minute latitude by one minute longitude. Ten grids in each zone were randomly selected for sampling by trawl each month. If a chosen grid was not free of obstructions or did not contain water >1m deep in at least one third of its area, an adjoining grid was chosen by random selection until these conditions were met. Half of the monthly trawl samples in each zone were collected during the first and second half of each month. No grid was duplicated in a month. TPWD provided data for the years 1982-2005. Once on site, hydrological and weather data were collected and recorded. A Kimmerer water sampler (or equivalent) was used to collect water from about 0.3 m (1 ft) off the bottom of each trawl site prior to trawling. Salinity (ppt) and water temperature (degrees C) were measured from bottom water using an appropriate instrument or meter (YSI, HACH, or equivalent). The same parameters were measured from surface water. Trawls were towed in a circular pattern to keep prop-wash out of the net and to stay near the center of each designated grid. All estuarine trawl tows were targeted to last 10 minutes, but actual duration was recorded. Towing vessels ranged from 6-7 m (22-24 ft) aluminum skiffs powered by outboard engines used in shallow areas, to 10-16 m trawler research vessels powered by inboard diesel marine engines used in deeper open-bay and Gulf waters. Trawls were towed at 4.8 kph (3 mph), and the start, midway, and end locations of each trawl were recorded. Water depths (m) were recorded at the start and end of each tow. All organisms caught were identified to the lowest specific taxonomic level possible, usually to genus and species. Up to 50 shrimp of each species, 35 blue crabs, and 19 individuals of all other species were measured in each sample. Fish and shrimp were measured for total length (TL) and crabs for total width (from tip to tip of lateral spines) (Martinez-Andrade and Fisher 2010). Process_Date: 2013 Process_Step: Process_Description: Catch data in trawls were converted to numbers caught per hectare (#/ha) using the tow times and calculated conversion factors. The conversion factor was calculated based on an assumed 80% spread of the width of the trawl webbing along the headrope (defined here as the headrope length) and the estimated distance towed in one minute calculated from reported tow times. The conversion factor is equal to the time needed (in minutes) for the trawl to cover one hectare. To calculate the CPUE the following formula was used: Conversion factor / Tow duration (min) X Number caught = #/ha. The conversion factor for Texas was calculated to be 27.56.
