Characterization of Atlantic Cod Spawning Habitat and Behavior in Icelandic Coastal Waters
The physical habitat used during spawning may potentially be an important factor affecting reproductive output of broadcast spawning marine fishes, particularly for species with complex, substrate-oriented mating systems and behaviors, such as Atlantic cod Gadus morhua. We characterized the habitat...
