Peru Halts Anchoveta Fishing as El Niño and Overfishing Collide
Peru suspended its anchoveta fishing season in June 2026, later imposing a full closure as warming seas and decades of overfishing threaten a global supply chain.
Peru's government suspended anchoveta fishing on June 10, 2026, initially as a temporary measure before converting the ban into a total closure in mid-August — a drastic step with sweeping consequences for global aquaculture and agriculture supply chains.
The Peruvian anchoveta, known scientifically as Engraulis ringens, is not the briny Mediterranean fish found in pasta sauces and salad dressings — that is a distinct species. Peru's variety has accounted for roughly one-tenth of the entire global commercial fishing catch since 1970, a share larger than any other single fish species on Earth.

More than 90% of the anchoveta catch never reaches a dinner plate. Instead, it is rapidly processed into fishmeal and fish oil, then shipped worldwide to supply fish farms, shellfish operations, seaweed producers, factory farms, and nutritional supplement manufacturers. A prolonged closure therefore ripples far beyond Peru's coastline, tightening feed supplies for aquaculture industries that millions of consumers depend on.
Authorities cited a combination of supercharged El Niño-driven ocean warming and the cumulative damage of decades of overfishing as the drivers behind the stock collapse. The decision, while economically painful for Peru, reflects a broader reckoning facing fisheries managers globally as climate disruption compounds pressure on already-stressed marine populations.
