The Pacific Sierra is a ray-finned bony fish in the family Scombridae, better known as the mackerel family. More specifically, this fish is a member of the tribe Scomberomorini, the Spanish mackerels.
How To Identify:
The Pacific Sierra is most easily distinguished by pigment and color pattern. It is silver-blue above and silvery white on the lower sides and belly with a series of yellow-brown spots on the sides. The anterior half of the first spiny part of the dorsal fin is jet black, in contrast to the lighter remainder of the fin.
How To Catch:
The Pacific Sierra is a fishing resource caught seasonally in the artisanal fishery of the north-west Mexico coast, mainly between October and July. In this fishery, gill nets 160 m long and 3 m deep are used, with a mesh size between 6.98 and 7.62 cm, which are placed perpendicularly to the coastline at sunset and checked regularly. Anglers employ a variety of natural baits and artificial lures with wire leaders to guard against their sharp teeth.
The Pacific Sierra are found from La Jolla in Southern California, south to the Galapagos Islands and to Paita, Peru. They can also be found from Antofagasta, Chile.
