Anchoveta (Engraulis ringens) has a wide geographical distribution in the South Eastern Pacific Ocean, from Zorritos (4°30’ S) in Northern Peru to Chiloé (42°30’ S) in Southern Chile (Serra et al., 1979). There are three different anchoveta stocks (Cahuin et al. 2015) (Mendo 2018):
1. the Northern-Central Peruvian stock, managed by Peru - this profile;
2. the Southern Peru/ Northern Chile stock, managed by both Peru and Chile; and
3. the Central-Southern Chile stock, managed by Chile.

The stock expands in warmer years up to the Gulf of Guayaquil (3°00’ S), in Ecuador (Instituto Nacional de Pesca, 2009), where a purse seine fishery operates, but since 2012 that the anchoveta hasn't yielded significant catches (Instituto Público de Investigácion de Acuicultura y Pesca 2021).
