Rapid effects of a fishing closure on whitefish (Coregonus maraena) in the northern Baltic Sea
Areas closed to fishing year-round (no-take zones, NTZs) or during spawning time (spawning closures) are used as a management tool to increase declining fish populations. We evaluated the effects of a 147 km2 NTZ and a 3980 km2 spawning closure on whitefish populations in the northern Baltic Sea, an...
