Overview
Oceans & Range: Eastern Pacific Ocean — from Alaska south to Chile, most abundant from California to Baja California. Found in large open-water schools from the surface to 500 feet. A member of the jack family (not a true mackerel) — identified by a series of scales (scutes) along the lateral line toward the tail.
Preferred Water Temperature: 58°F–68°F. A cool-water schooling species common in offshore and nearshore California waters. Often found associated with kelp paddies and floating debris offshore.
Size & Weight: Typically 0.5–1.5 lbs and 10–14 inches. Maximum approximately 5 lbs. World record: 5 lbs 6 oz. Common bycatch on California party boats. Good eating — mild, white meat when properly prepared. Also used as live bait.
Best Lures: Small chrome jigs and feather jigs produce quick catches. Sabiki rigs fill the livewell fast. Small spoons work near the surface.
Best Baits: Small pieces of squid and anchovy work well. Easy to catch and often used as live bait for Yellowtail and other larger species. A fun light tackle species when specifically targeted.
