Fish Assemblages in Seagrass (<i>Zostera marina</i> L.) Meadows and Mussel Reefs (<i>Mytilus edulis</i>): Implications for Coastal Fisheries, Restoration and Marine Spatial Planning

Seagrass meadows and mussel reefs provide favorable habitats for many fish species, but few studies have compared the associated fish assemblages directly and examined the influence of environmental variables. Knowledge of fish assemblages associated with disparate habitats is needed for the conserv...
