Turtles are commonly caught in fishing gear in the sounds of North Carolina, particularly in the fall months when both turtles and flounder are migrating to the ocean. Gill nets, in particular, have been implicated in large mortality events and as a result this type of fishing gear has been restricted to certain parts of Pamlico Sound. In addition, the fall flounder gill net fishery has been closed prematurely in the past few years due to observed mortalities of turtles. We are studying interactions between turtles and gill nets by tracking the movements of turtles in and around Pamlico Sound during the fall flounder season and comparing the distribution of turtles with that of gill nets. In addition, we hope to gain valuable life history information by following the migration patters of individuals. We work closely with researchers from the Southeast Fisheries Science Center, NOAA Fisheries, in this program. This research is funded by the North Carolina Sea Grant's Fisheries Resource Grant program. For more information, please see the report: Habitat Use of Sea Turtles in Relation to Fisheries Interactions. This dataset is a summarized representation of the telemetry locations aggregated per species per 1-degree cell.
