Causes and consequences of fleet diversity in fisheries: The case of the Norwegian Barents Sea cod fishery
Abstract Fisheries operate under fluctuating environmental conditions, targeting fish stocks that appear in varying densities in different areas, often with abrupt and unexpected local changes. Physical conditions, markets and management regulations constrain vessels in different and varying ways. T...
