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 Marine Fisheries Division of the Louisiana Department of Wildlife and Fisheries (LDWF), as well as associated hydrographic data. Trawl data were used to calculate CPUE (catch per unit effort) at each station for the years 1986 through 2007. 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 Louisiana only. The CAGES database is intended for scientific research only. completed Dr. Harmon Brown NOAA National Marine Fisheries Service, Southeast Fisheries Science Center, Galveston Laboratory 409-766-3500 Galveston Laboratory, 4700 Avenue U Galveston TX 77551 USA Monday - Friday, 8am - 5pm, Central Standard Time pointOfContact unknown CoRIS_Metadata NCEI Geoportal Filter comparative assessment of gulf estuarine systems CAGES Louisiana Department of Wildlife and Fisheries Marine Fisheries Division estuary coastal bay distribution abundance occurrence fisheries fishery independent data CPUE catch per unit effort trawl finfish invertebrate nekton vertebrate crustacean salinity temperature turbidity air temperature water temperature hydrological hydrographic saltwater species brackish water species freshwater species theme None Gulf of Mexico Gulf Coast Louisiana Barataria Bay Black Lake Breton Sound Chandeleur Sound Grand Lake Lake Borgne Lake Calcasieu Lake Pontchartrain Lost Lake - Four League Bay Terrebonne-Timbalier Bays Vermillion-Cote Blanche Bays place None OCEAN BASIN > Atlantic Ocean > Gulf of Mexico > Louisiana COUNTRY/TERRITORY > United States of America > Louisiana OCEAN BASIN > Atlantic Ocean > Gulf of Mexico place CoRIS Place Thesaurus Numeric Data Sets > Biology theme CoRIS Discovery Thesaurus EARTH SCIENCE > Oceans > Marine Biology > Marine Invertebrates EARTH SCIENCE > Oceans > Salinity/Density > Salinity EARTH SCIENCE > Oceans > Ocean Chemistry > Oxygen EARTH SCIENCE > Oceans > Marine Biology > Fish EARTH SCIENCE > Oceans > Ocean Temperature > Water Temperature theme CoRIS Theme Thesaurus otherRestrictions otherRestrictions Access Constraints: None Use Constraints: None Distribution Liability: NOAA and NODC make no warranty, expressed or implied, regarding these data, nor does the fact of distribution constitute such a warranty.

Tables/files and fields, in the order they occur in the csv files, are as follows: LA CPUE (Sample Code, YYYY, MM, DD, Water Body, Scientific Name, CPUE); Louisiana Lengths (Sample Code, Species Code, Length); Louisiana Species (Species Code, Scientific Name, Common Name); Louisiana Stations (Station Code, CSA, Station, Latitude, Longitude, Site Name, Water Body); Louisiana Trawls (Sample Code, Species Code, Total Number); Louisiana Samples (Sample Code, Station Code, YYYY, MM, DD, Time, Duration); Louisiana Hydrological (Sample Code, Surface Salinity, Bottom Salinity, Air Temperature, Surface Water Temperature, Bottom Water Temperature, Turbidity). In the Louisiana Stations table CSA stands for Coastal Study Area. Latitude and Longitude are provided in decimal degrees; depths are in meters (m); and Times is local time. Units of measure for other fields are as follows: CPUE (number caught per hectare (#/ha)), Length (mm), Time (HH:MM), Duration (Minutes), Salinity (ppt), Air Temperature (Degrees Celsius), Water Temperature (Degrees Celsius), Turbidity (NTU (Nephelometric Turbidity Unit)). Note: Temperature values have known issues, possibly due to entry and or conversion errors. Entity and Attribute Detail Citation: Brown, H., T.J. Minello, G.A. Matthews, M. Fisher, E.J. Anderson, R.

The Louisiana Department of Wildlife and Fisheries (LDWF) Marine Fisheries Division conducts fishery-independent sampling to assess the state's natural resources, to aid in setting opening and closing dates for fisheries, and to aid in setting catch limits for regulated species. Fishery-independent trawl sampling using the 4.9-m (16-ft) flat otter trawls was scheduled for each year as follows: Nov-Feb (bi-weekly) and Mar-Oct (weekly). Hydrographic data were collected before each trawl tow. Temperature and salinity were measured from surface and bottom waters, and turbidity measured from surface water. Water depth was recorded at the start of the tow. The trawl was towed for 10 minutes: timed from when the trawl first began to move forward to when it stopped forward movement. Towing speed was 4.8 kph (3 mph), and the tow path was either weaving, circular, or straight depending on depth and design of the water body (bayou or open bay), allowing the prop-wash to pass to the side or over the top of the trawl. LDWF provided data for the years 1986-2007. All organisms caught in the trawl were identified to the lowest taxon possible (usually genus and species), counted, and up to 50 of each species were measured in 5-mm intervals. Size measurements were taken as follows: shrimp - total length (TL) measured from the anterior tip of the rostrum to posterior tip of the telson; crabs - carapace width (CW) measured from tip to tip of posterior -lateral spines of the carapace; and fish - measured as total length (LDWF 2002). 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 Louisiana was calculated to be 32.04.
