The development and evaluation of small specialized turtle excluder devices to reduce sea turtle bycatch in small skimmer nets (NCEI Accession 0226612)

browse graphicPreview graphic
This dataset contains records of Gulf of Mexico (GOM) white shrimp (Litopenaeus setiferus), and brown shrimp (Farfantepenaeus aztecus), and bycatch (other invertebrates, crustaceans, fishes, debris) which can be used to test for general usability of TEDs in the commercial small skimmer fisheries. The dataset contains records of targeted white shrimp and brown shrimp and bycatch (counts and CPUE) collected during tests of TEDs in small skimmer nets conducted in the north GOM near Dulac, LA and Ocean Springs, MS. Data also include testing information such as depth, boat speed, and georeferencing information.

Purpose The purpose of the dataset is to to test for target shrimp retention, bycatch reduction, and general usability of TEDs in the commercial small skimmer fisheries. Proposed rulemaking would extend TED requirements to other trawl types such as small skimmers but there has been limited development of specialized TEDs for these smaller trawls. This dataset is the result of tests of a top opening TED with a minimum width of 28-in (71-cm) and height of 24-in (61-cm) in small skimmer net determine its effectiveness in this fishery.
