Fishermen commonly looking for tuna, swordfish, and shrimp also ensnare sea turtles of various species. The primary threat to leatherback turtle populations worldwide is bycatch in fishing gear.
Bycatch primarily occurs in gillnets, longlines, trawls, and trap/pot fisheries. Sea turtles have been intentionally killed for their meat and skin for hundreds of years. Worldwide, hundreds of thousands of sea turtles a year are accidentally caught in shrimp trawl nets, on longline hooks and in fishing gillnets.

It is the only living species in the genus Dermochelys and family can easily be differentiated from other modern sea turtles by its lack of a bony.
(a) Tracking summary. Female leatherback turtles (n = 25; curved carapace length ± 6 cm, mean ±1 s.d., range – cm) were satellite-tracked for ± days (mean ±1 s.d., range 39– days) while undertaking post-nesting dispersal from the coast of Gabon (figure 1 and electronic supplementary material, table S2).Of these individuals, 17 were satellite-tracked for more than.
