Evaluating genetic traceability methods for captive bred marine fish and their applications in fisheries management and wildlife forensics
Growing demands for marine fish products is leading to increased pressure on already depleted wild populations and a rise in the aquaculture production. Consequently, more captive bred fish are released into the wild through accidental escape or deliberate restocking, stock enhancement and sea ranch...

Growing demands for marine fish products is leading to increased pressure on already depleted wild populations and a rise in the aquaculture production.

The increased mixing of captive bred fish with wild conspecifics may affect the ecological and/or genetic integrity of wild fish populations. From a fisheries management perspective unambiguous identification tools for captive bred fish will be highly valuable to manage risks.
