Study finds catch-and-release fishing injuries, especially to eyes, raise salmon mortality up to 40%.

A study from the University of British Columbia reveals that catch-and-release fishing practices that injure salmon, especially their eyes, can lead to higher mortality rates, up to 40% for chinook salmon. Researchers suggest using smaller hooks, avoiding landing nets, and handling fish minimally to boost survival rates. The study tracked over 1,500 salmon and found that eye injuries alone increased mortality by 20%. It also highlighted that water temperatures over 18 degrees Celsius can harm salmon.
