Against overfishing: Save the oldies! Harvest slots protect fish stocks without compromising fisheries yield

Measures against overfishing tend to protect young, immature fish through measures such as minimum-landing sizes. However, a team of researchers led by Professor Robert Arlinghaus from the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) and the Humboldt-Universität zu Berlin recommends also keeping the particularly large megaspawners alive in addition to the youngsters. This type of management achieves good compromises between the demands of commercial and recreational fisheries and the desire to conserve the reproductive capacity of fish populations.
