Technologies and Tools Used in Bycatch Reduction
| Technology/Tool | Description | Application in Bycatch Reduction | Effectiveness |
|---|---|---|---|
| Excluder Devices (TEDs and BRDs) | Turtle Excluder Devices (TEDs) and Bycatch Reduction Devices (BRDs) are net modifications that allow non-target species to escape. | Used in shrimp trawling and other trawl fisheries to reduce capture of turtles, juvenile fish, and other bycatch species. | TEDs can reduce turtle bycatch by up to 97%. BRDs vary in effectiveness but often reduce fish bycatch by 30-60%. |
| Acoustic Deterrent Devices (Pingers) | Underwater sound emitters designed to alert marine mammals and reduce entanglement risk. | Deployed in gillnets and other static gear fisheries to deter dolphins, porpoises, and seals from nets. | Can reduce harbor porpoise bycatch by approximately 50-90%, depending on species and environment. |
| LED and Light-Emitting Devices | Visual stimuli using LED lights attached to nets or lines. | Applied in longline and gillnet fisheries to modify behavior of non-target species such as sea turtles and seabirds. | Studies indicate up to 50% reduction in turtle bycatch and significant seabird avoidance. |
| Selective Hook and Bait Designs | Use of circle hooks and specific bait types to minimize incidental catch of non-target species. | Common in longline tuna and swordfish fisheries to reduce seabird and turtle bycatch. | Circle hooks reduce sea turtle bycatch mortality by over 60%; bait changes improve selectivity. |
| Escape Openings and Net Modifications | Structural gear changes like escape panels and enlarged mesh sizes to facilitate bycatch escape. | Used in various net fisheries to allow smaller or unwanted species to exit while retaining target species. | Effectiveness varies but often achieves 30-70% reduction in specific bycatch species. |
| Real-Time Bycatch Monitoring Systems | Use of underwater cameras, sensors, and software for immediate identification and mitigation of bycatch events. | Implemented on vessels to enable timely adjustments in gear deployment and retrieval. | Improves compliance and reduces bycatch through active management and data collection. |
