Skimmer trawls are utilized throughout the southeastern United States to target penaeid shrimp (Penaeidae). Because the codends of these trawls can be readily retrieved, skimmer trawls are allowed to utilize restricted tow times (55 and 75 minute, seasonally) in lieu of Turtle Excluder Device (TED) requirements as a sea turtle bycatch mitigation measure. However, observations aboard commercial vessels indicate that tow times are often exceeded. In 2013, the Southeast Fisheries Science Center Mississippi Laboratories began independent skimmer trawl TED testing aboard the NOAA vessel, RV Caretta. Testing was conducted from 2013 to 2015 on traditional commercial fishing grounds located in the internal coastal waters of Mississippi and Louisiana. The experimental design consisted of paired comparisons designed to examine shrimp catch retention and bycatch. A TED was installed in one net (treatment), while the other was left naked with no TED installed (control). The TED was switched between port and starboard nets daily to remove potential vessel side bias. Data consists of tow level data for each net (treatment vs control) for five major catch categories; shrimp, finfish, non-shrimp crustaceans, other invertebrates, and debris. Start and end locations, times, and depths were recorded for each tow along with vessel identifier, date, tow speed, TED configuration, and location of the TED (port vs starboard). Data were used to determine TED efficiency with regard to shrimp catch and bycatch reduction.
To independently evaluate and test the use of skimmer trawl Turtle Excluder Devices.

dataset
Trawl catch is sorted to shrimp, finfish, non-shrimp crustaceans, other invertebrates, and debris. Shrimp and selected finfish are identified to species. Catch and length frequency data are recorded onto datasheets. Datasheets were checked in the field after sampling and data were checked after data entry. The principal investigators review the data for content to ensure the relevance/accuracy of data collected.
