Trophy bass 2007 download full8/28/2023 Twelve tagged fish were caught and released in the warm-water period, of which four died (33%). We implanted radio transmitting tags in muskellunge ≥ 650 mm in winter 2020 (N = 45) and 2021 (N = 50) to monitor fates of fish that were subsequently caught and released during the warm-water period (July – August). Therefore, we used a combination of a radio telemetry study and individual-based growth model simulations to evaluate the effects of warm-water C&R mortality on the length potential of muskellunge in the James River, Virginia. Because muskellunge are a coolwater species, muskellunge anglers and biologists have expressed concerns regarding the population-level effects of additional mortality from C&R during periods of elevated water temperatures. Catch-and-release (C&R) has become a popular practice in many fisheries, but especially in muskellunge Esox masquinongy fisheries where voluntary release rates of legal-sized fish have approached 100%.
