Choose fish with a short life cycle. They reach maturity and reproduce more quickly, which helps stocks regenerate faster.
For example, mollusks and populations of small pelagic fish that live near the ocean surface can multiply rapidly.
Fish that live at great depths, like luvar, grenadier and halibut, grow very slowly, have a long life expectancy (luvars can live up to 160 years) and take a long time to reach sexual maturity. A generation of luvars needs 17 to 21 years to renew itself. Some fish that live on the seabed, such as monkfish, are very poor swimmers. Already vulnerable to disturbances in the ecosystem, they are even more vulnerable to overfishing.
Fish with long life cycles should only be eaten very infrequently.
