Lingcod update: Stock enhancement under study as management tool in U.S. pacific northwest

摘要

The authors have begun a project to further investigate stock enhancement as a tool for rebuilding depleted lingcod stocks in Puget Sound in Washington, USA. In raising lingcod larvae in large mesocosm bags, studies are addressing challenges that include cannibalism, fluctuating water quality and introduced predators, Refined tag and release methods will test hypotheses about habitat preferences, movement, recruitment success and ecological impacts of lingcod releases.
