Canada: How changing catch-and-release fishing practices can boost salmon survival

Tridge summary

A recent study conducted by the University of British Columbia, funded by the Sport Fishing Institute of B.C., has revealed that catch-and-release sportfishing practices, particularly those that result in salmon injuries, may lead to a higher mortality rate than previously assumed. The study found that chinook salmon mortality can reach up to 40% under certain conditions, with injuries to the eyes being a significant factor. However, the research also highlights practical ways to enhance salmon survival, such as using smaller hooks and avoiding nets. The study also raises concerns about the effects of climate change on salmon, suggesting that anglers should cease catch-and-release practices when water temperatures reach 18 C or higher. The findings have been well-received by the Sport Fishing Institute of B.C. and the Fisheries Department, with a call to action for anglers to adopt these practices to support the long-term sustainability of salmon populations.

VANCOUVER — A study has found catch-and-release sportfishing practices that leave salmon with injuries, particularly to their eyes, cause higher mortality than earlier research suggested. Scott Hinch, who led the study by researchers at the University of British Columbia, said mortality among chinook salmon could be as high as 40 per cent, depending on environmental conditions and injuries sustained during capture and release. At the same time, the years-long research that was supported by the Sport Fishing Institute of B.C. found that a series of changes in anglers' practices could boost salmon survival. Hinch said these may be as simple as using smaller hooks, avoiding using nets to land fish and handling fish as little as possible. "You can make those decisions as an angler, you know, make sure that when you are releasing, you're doing it the best way possible," said Hinch, associate dean and professor in the university's department of forest and conservation science. "I'm not ...
