Using automated video analysis to study fish escapement through escape panels in active fishing gears: Application to the effect of net colour.
The focus of this study was to compare two selective devices in a trawl by automated counting of fish escapements through each selective device (a white and black square mesh panel) based on video sequencing and an algorithm for automated object detection and tracking. The software detected a significant difference in fish escapement rate according to net color- 60% of all fish escaped through the white panel, suggesting that net color influences the escape rate of fish.

The efficacy of illumination to reduce bycatch of eulachon and groundfishes before trawl capture in the eastern North Pacific ocean shrimp fishery
This study examined the extent that eulachon (Thaleichthys pacificus) and groundfishes escape trawls in response to artificial illumination. Using a double-rigged trawler, catch efficiencies were compared for ocean shrimp, eulachon, and groundfishes between an unilluminated trawl and a trawl illuminated with five green LEDs along its fishing line. Results showed a significant reduction in the bycatch of eulachon and yellowtail rockfish (Sebastes flavidus) in the presence of illumination.

Cost‐effective mitigation strategies to reduce bycatch threats to cetaceans identified using return‐on‐investment analysis
Solutions to mitigate cetacean bycatch have targeted specific fisheries and gears, however, these targeted mechanisms can be effective if interactions occur only between a particular population and gear type or fishery. Most dolphin and whale populations face incidental capture from multiple fisheries and gears. Accordingly, broad-scale spatial approaches to mitigation are needed to address bycatch across multiple species at the scale at which the species occur.
An illuminating idea to reduce bycatch in the Peruvian small-scale gillnet fishery.
Researchers deployed LED lights on the floatlines of paired gillnets (control vs illuminated net) during 864 fishing sets by small-scale vessels departing from three Peruvian ports between 2015 and 2018. Bycatch probability per set for sea turtles, cetaceans and seabirds as well as catch per unit effort (CPUE) of target species were analyzed for illuminated and control nets using a generalized linear mixed-effects model (GLMM).

Release efficiency and selectivity of four different square mesh panel configurations in the Basque mixed bottom trawl fishery
Square mesh panels (SMPs) have been proposed as a bycatch reduction measure that can increase the escape of non-target fish species without significantly changing the economic value of the catch.
