Description
Ann-Elin Synnes and co-authors compared fish communities under different protection regimes in Norway in two thousand twenty-three. When top predators vanish, mid-level predators can multiply and reshape the food web, an effect called mesopredator release. Cod is a likely top predator in these coastal waters.
They sampled fish with fyke nets over three seasons in national park waters open to fishing and in a nearby seascape with protected zones. Cod in the protected seascape were much larger on average. Open waters held more mesopredator fish. The pattern fits the release hypothesis: protecting top predators helps them control mid-level fish. The authors link today's coastal fish state to long fishing pressure on large predators.
