Fisheries bycatch threatens sessile communities of the Great Amazon Reef System

Submitted by allykristan on

This paper assessed richness, distribution, and incidental catch of benthic sessile invertebrates in the Great Amazon Reef System (GARS)  based on records and photographs collected from onboard observers between 2015 and 2022. In total, 54 distinct species were recorded as bycatch, with most being echinoderms. Gillnet and trawl fisheries pose great threats to the GARS, and over time this bycatch may profoundly disturb benthic reef communities and therefore reduce fishery yields.

Unravelling the deep: Assessing the bycatch of deep-sea elasmobranchs in crustacean bottom trawl fisheries in Portugal

Submitted by allykristan on

This study measured deep-sea elasmobranch (DSE) bycatch on a commercial crustacean bottom trawler off of southern Portugal between June 2020 and May 2022, and collected data from Global Fishing Watch to estimate the bycatch of deep-sea sharks since 2017, which is the year that trawling below 800m was banned in the region. DSE represents a high proportion of total catch biomass, especially at depths below 800m; despite EU regulations restricting fishing to only occur above 800m, bottom trawlers were regularly observed operating below that depth.

s net illumination a silver bullet for mitigating sea turtle bycatch in set net fisheries?

Submitted by allykristan on

The authors trialed the effectiveness of green LED lights to reduce sea turtle bycatch in bottom-set gill and trammel nets in the northeastern Adriatic Sea (territorial waters of Croatia and Slovenia) . The result was no significant change in sea turtle bycatch, and a significant decrease (35%) of primary target catch. Although net illumination has been highly effective (up to 93%) in reducing sea turtle bycatch in other regions, this study highlights the importance of regional variability in mitigation measures.

Quantifying bycatch of cold-water gorgonians to propose a dynamic management strategy for sustainable artisanal fishing on the mediterranean continental shelf

Submitted by allykristan on

Through on-board fishing vessel observations and Autonomous Underwater Vehicle (AUV) transects, this study explored the impact of trammel nets on cold-water gorgonian (soft coral) populations in the Northwestern Mediterranean Sea. High bycatch of gorgonians, especially larger colonies with greater than average height, was observed in the majority of assessed nets at an average rate of 2.4 ± 0.8 colonies or fragments per 200m of net. Impact was higher in specific areas below 80m depth and where wave heights were greater than 1m.

Successful collaborative trials of simple gear modifications to reduce entanglement of whales and other megafauna in Scotland’s static pot (creel) fisheries

Submitted by allykristan on

The authors worked with creel fishers to trial and assess whether sinking rope was practical to fish with in Scottish inshore waters, and therefore to reduce entanglement risk of minke whales, humpback whales, and other megafauna. Overall, the fishers reported few problems with the modified gear, and the gear performed well underwater according to Remotely Operated Vehicle (ROV) footage and sensors. Sinking rope may be a simple, viable option to reduce entanglement risk in the Scottish creel fishery.
