This film explores how different fishing gear types are tested to assess their impact on salmon survival, ensuring that future fisheries minimize harm to unintended species and support sustainable fishing practices.
Vanessa Castle explains how scientists track salmon populations using data collection methods like sonar, screw traps, and surveys to estimate migration survival rates, predict future returns, and help set sustainable fishing regulations.
Vanessa Castle explains how researchers conduct surveys of Chinook salmon, counting fish and nests to estimate juvenile migration, track population trends, and guide sustainable fishery management, especially after environmental changes like dam removal.
This video explores how dam construction devastated salmon populations by blocking habitat and starving rivers of sediment, while recent dam removals have begun restoring spawning grounds and increasing fish numbers, offering hope for future recovery.
This Film explores the journey of salmon from spawning in freshwater nests to migrating to the ocean, maturing over several years, and returning to their birthplace to reproduce.
