TPWD HARC Texas Coastal Fisheries Lower Laguna Madre Gill Net
Dataset Identification:
Resource Abstract:
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 Lower Laguna Madre 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.<br> <br> Attached files include:
