Canada: Marine Institute studying the better way to sustain commercial harvest of challenging redfish

Tridge summary

A research team led by Shannon Bayse from the Marine Institute in St. John's, Newfoundland and Labrador, is developing sustainable gear for the soon-to-be-reopened commercial redfish fishery, following a moratorium lifted due to a significant mature fish biomass buildup. The team's focus is on a slow-growing species, aiming to minimize the catch of undersized redfish by testing and validating a selective T90 mesh codend net design. This net allows smaller fish to escape, reducing the risk of overexploitation and ensuring the sustainability of the redfish stock. Video evidence confirms that small fish can successfully escape from the net at the ocean floor, a crucial finding for the effectiveness of this gear in maintaining a balanced underwater ecosystem. This innovation is seen as a critical step in ensuring the long-term sustainability of the redfish fishery, highlighting the importance of scientific research in informing fishing practices for challenging species like redfish.

ST. JOHN'S, N.L. — With a Newfoundland and Labrador commercial redfish fishery about to open for the first time in almost three decades, the research work Shannon Bayse is involved in may net more interest. Bayse is a research scientist at Marine Institute in St. John’s and presented on his work at the ICES/FAO Working Group on Fishing Technology and Fish Behaviour conference, happening at Memorial University’s capital campus this week. The working group conference is supported by the International Council for the Exploration of the Sea and the Food and Agriculture Organization of the United Nations. Bayse is part of a team of researchers studying the best choice for sustainable gear used to catch redfish. Slow-growing species The peculiar biology of redfish is crucial to what type of gear is optimal, explained Bayse. Redfish are a slow-growing species, which poses a challenge for managing them. A moratorium was placed on redfish in 1995 after the stock collapsed, but there were ...
