The Pacific Fishery Management Council (Pacific Council) has expressed the desire for the development and design of alternative swordfish gears that reduce the potential for interactions with bycatch species of concern (i.e., turtles and marine mammals) along the U.S. west coast. Among the gears recently tested off California is deep-set buoy gear (DSBG), a configuration that was patterned afte...
Blubber Testosterone: A Potential Marker of Male Reproductive Status in Short-Beaked Common Dolphins
A novel molecular technique was used to measure blubber testosterone (BT) in 114 male short-beaked common dolphins, Delphinus delphis, collected from incidental fishery bycatch and strandings. When these concentrations were compared across maturity states, the mean (± SEM) BT levels of mature D. delphis (14.3 ± 3.0 ng/g) were significantly higher than those of pubertal (2.5 ± 0.5 ng/g, P = 0.00...
Many seabirds are attracted to fishing boats where they exploit foraging opportunities, often involving bycatch-related mortality. Bycatch risk is generally estimated by overlapping ranges with coarse-scale monthly maps of efforts, but a more direct estimation would be the time birds actually spend attending boats. Here we matched data from Automatic Identification Systems all declared in South...
Fisheries bycatch conservation and management can be analyzed implemented through the biodiversity mitigation hierarchy using one of four basic approaches: (1) private solutions, including voluntary, moral suasion, intrinsic motivation; (2) direct or “command-and-control” regulation starting from fishery authority down to vessel; (3) incentive- market-based alter producer consumer behavior deci...
• Simple modification of fishing gear mitigates bycatch problem in shrimp fishery. Large mesh panel last upper belly section the trawl reduces bycatch. do not lead to significant loss. In Northeast Atlantic deep-water ( Pandalus borealis ) fishery, juvenile fish and represents a problem. This study evaluated if inserting 200 mm size top-panel three sections tapered could reduce juveniles while ...
Fisheries bycatch is the greatest threat to migratory, long-lived marine animals. Addressing ultimately requires changing fisher behaviour, yet social and behavioural sciences are rarely applied mitigation, with an absence of theory-informed behaviour change interventions. Moreover, mitigating particularly challenging in small-scale mixed-species fisheries (SSFs), where perceptions target non-t...
