Peruvian anchoveta
Small Pacific fish vital for fishmeal and growing food use
The Peruvian anchoveta is a small schooling fish from the Southeast Pacific. It supports the world's largest wild fishery by volume. Most catches become fishmeal, but direct human consumption is rising.
- Largest wild fishery by volume globally
- 99 percent of catch becomes fishmeal or oil
- Matures at one year and 10 cm length
- Diet consists mainly of krill and copepods
- Populations crash during strong El Niño events
What it is
This species belongs to the anchovy family. It grows to a maximum length of 20 cm. Adults typically reach maturity at 10 cm. The fish has a slender body suited for fast swimming in large groups. It lives in the cold waters of the Humboldt Current system. Its silver scales help it blend into the open water while feeding.
Where it lives
These fish inhabit the southeastern Pacific Ocean. Their range extends along the coasts of Peru and Chile. They stay within 80 km of the shoreline. Huge schools form in these coastal zones. The cold nutrient-rich upwelling supports their massive populations. Warm events like El Niño can disrupt this habitat by lowering the thermocline depth.
How it lives
Anchoveta feed primarily on larger zooplankton. Krill and large copepods provide most of their energy. Earlier views suggested they ate mostly phytoplankton, but recent studies correct this. They live for up to three years. Predators include larger fish, seabirds, and marine mammals. They swim in dense schools for protection and efficient feeding.
Breeding and life cycle
Fish reach reproductive age at about one year. They spawn when they reach 10 cm in length. Fisheries often harvest them earlier, at six months and 8 cm. This early capture impacts the breeding stock. Population levels fluctuate with environmental conditions. Strong El Niño events reduce food availability and lower recruitment success.
Fish and people
This fish supports the largest wild catch globally. Most of the harvest becomes fishmeal and oil. Since 2005, more is used for human food. Canned products are marketed as Peruvian sardines. New items include jerky and steaks. The government assigns fishing rights to manage the resource. Quotas adjust based on estimated reproductive biomass.
Status and threats
Catches vary widely due to climate and fishing pressure. The 1972 El Niño caused a major crash. Stocks recovered by the mid-1990s. Recent years show declining volumes compared to other species. Management uses vessel catch limits to prevent overfishing. Scientists monitor biomass to set seasonal quotas. Data uncertainty affects these assessments.
Questions people ask about Peruvian anchoveta
Is Peruvian anchoveta the same as sardines?
No, they are different species. Anchoveta are marketed as Peruvian sardines to boost sales. True sardines are in higher demand globally. This culinary naming helps promote direct human consumption of anchoveta.
What do Peruvian anchoveta eat?
They primarily consume larger zooplankton. Krill and large copepods are their main energy sources. Earlier beliefs that they ate mostly phytoplankton have been corrected by recent scientific work on their diet.
Why do anchoveta catches fluctuate so much?
El Niño events warm the water and reduce nutrients. This lowers phytoplankton production and starves the fish. Overfishing also plays a role. Management quotas change based on estimated stock biomass each season.
Can humans eat Peruvian anchoveta?
Yes, though only one percent is used for food. Most becomes fishmeal. New products include canned fillets, jerky, and steaks. The government promotes these to increase direct consumption among locals and abroad.
