Atlantic cod Gadus morhua save energy on stone reefs: implications for the attraction versus production debate in relation to reefs
Reefs are structurally complex habitats that are degraded in numerous coastal areas. Structural complexity is often associated with elevated fish abundance, and recent studies have indicated that such structural complexity (e.g. reefs) not only acts as fish aggregators, but also increases fish produ...

Reefs are structurally complex habitats that are degraded in numerous coastal areas.
