Using Fishermen’s Ecological Knowledge to map Atlantic cod spawning grounds on Georges Bank
Abstract The spawning dynamics of Atlantic cod (Gadus morhua) on Georges Bank and Nantucket Shoals are not well understood. To address this uncertainty, we combined Fishermen’s Ecological Knowledge (FEK) with traditional scientific data to develop a more holistic understanding of cod spawning on Geo...
