This summary study describes all identified fishing techniques that have been used globally to reduce unintended species bycatch, to improve clarity on available techniques and highlight opportunities for further research and development. Of the total 55 techniques identified, the majority are specific to long-line fisheries and to designed to benefit small mammals, seabirds, and sea turtles. Additionally, the majority of techniques (81%) attempt to avoid contact of bycatch species with fishing gear altogether, rather than attempting escape or release.

By modeling (GLMs and GAMs) data from onboard observers and logbooks, the authors investigated patterns in loggerhead sea turtle (Caretta caretta) bycatch in bottom trawlers in the Southern Adriatic Sea. Results indicate that most bycatch occurs during the daytime and in shallower coastal waters, and that it increases temporally in summer and autumn. The study also identified two bycatch hotspots: the Gargano promontory and off the coast of Brindisi.

This summary study analyzes unintended horsehoe crab (Tachypleus tridentatus) bycatch in trawl and gillnet fisheries in the Letzhou Gulf, China. Estimates show at least 9120 ± 315 horseshoe crabs caught annually. Bycatch rates are heightened in spring and autumn, and in gillnet fisheries when compared to trawl fisheries. The study also highlights several zones/areas of the Letzhou Gulf with "abundant shoal resources" and higher bycatch rates.

The authors performed modeling on 10 years of logbook data to analyze environmental and operational factors that influence shark and odontocete depredation in the New Caledonian longline tuna fishery. Results suggest that there are "hotspots" of odontocete depredation, and that it is driven by environmental factors such as sea surface temperature and bathymetry, while shark depredation is driven by operational fisheries factors such as soaking time and number of hooks.

The authors developed a novel mitigation method for reducing seabird bycatch in gillnet fisheries in the Baltic Sea: looming-eyes buoys (LEB), an above-water visual deterrent. This method was trialed off of Sareemaa Island, Estonia, and was shown to reduce potential for long-tailed duck (Clangula hyemalis) bycatch by 20-30% within a 50m radius with a possible habituation effect within 62 days. These trials suggest that above-water visual deterrents such as LEBs could contribute to reduce seabird bycatch in combination with other management and mitigation measures.
