Jack mackerel (jurel) is the second largest fishery in the HCS. As with the anchoveta in Peru, this species is believed to be composed of a single stock. Jurel are a straddling species. This means the species is found both within and outside of the 200-mile economic exclusive zone. Jurel became an important fishery in the 1970s to alleviate the pressure put on the anchoveta stock. During the 1980s, however, the jurel decreased in population size due to poor recruitment and overfishing. Restrictions of jurel fishing were imposed in 1998 which led to regrowth of the population. Since 2002, the jurel population is now under full exploitation.
