Estimated bycatch rates of sea turtles in coastal southeastern US fisheries as a function of predicted abundance of turtles and fishing effort
Species | Shrimp trawl (km) | Bottom longline (km ∗ days) | Gillnet (km ∗ days) | Hook & Line (# of lines ∗ days) | Recreational (angler days) |
---|---|---|---|---|---|
Kemp’s ridley | 6 × 10 −10 (5 × 10 −11–5 × 10 −9) | 5 × 10 −10 (--) | 4 × 10 −6 (4 × 10 −7–4 × 10 −5) | – | 9 × 10 −10 (7 × 10 −11–2 × 10 −8) |
Green turtle | 5 × 10 −12 (2 × 10 −12–2 × 10 −11) | – | 5 × 10 −8 (--) | – | 5 × 10 −12 (2 × 10 −12–2 × 10 −11) |
Values indicate the geometric mean of all estimates, values in parentheses indicating the geometric mean of computed bycatch rates less than (lower bound) or greater than (upper bound) the geometric mean of all computed bycatch rates. Higher values indicate greater risk (i.e., catchability) to turtles of a given gear/fishery.
