Geographical Distribution

FAO Fisheries and Aquaculture Department Launch the Aquatic Species Distribution map viewer

Souther Pacific. Along coast of Chile and Perú (including Central and Chinha Is.) and Australian waters.

Habitat and Biology A epipelagic species;often confined to neritic zones of coast or island shelves, banks and sea mounts;a schooling species.Feeding primarily on crustaceans (copepods), shrimps, but also small fishes and squid. All have pelagic eggs and spawning generally occurs during the summer.

Size Attains a maximum size of 60 cm (24 in) or not very more.

Interest to Fisheries Caught commercially with trawls, purse seines ("small pelagic purse seining, mackerels purse seining"), traps and on line gear. Marketed fresh. The total catch reported for this species to FAO for 1999 was 1 423 447 t. The countries with the largest catches were Chile (1 219 689 t) and Peru (184 679 t). Utilized canned for human consumption and also made into fishmeal.

Trachurus murphyi

Local Names English : Peruvian horse mackerel , Peruvian jack mackerel . Japanese : Chiri-maaji . Spanish : Boliche , Furel , Furrel , Hurel , Jurel , Jurel del norte , Jurelito , Pavo , Yurel .

Remarks The common jack mackerel (Trachurus declivis ) is almost identical in appearance to the Inca scad or Peruvian jack or horse mackerel, or Southern jack mackerel (FAO name). The best characteristics for differentiating betwen the two species are total number of gillrakers (50-57 in T. declivis and 51-65 in T. murphyi ) and the number of scales and scutes in the lateral line (81-82 in T. declivis and 89-113 in T. murphyi ) and their relative heigths.
