That's right. Fish stocks are defined by a mix of biology and management. In biology, we look at the DNA profile of fish to determine subpopulations. We also take their behaviour into account. You can track cod through scientific surveys, but also through cod tagging throughout the offshore area. Sometimes they're implants with detectors that are inserted into cod in offshore areas to record fish passages. The fish can also be fitted with metal tags. Because we know where they were first caught and tagged, once they're recovered, that gives us an idea of the fish redistribution.
