Identifying features

Dark green-blue back with wavy, worm-like dark bars breaking into spots along the flank
Silvery belly with a series of dusky spots below the lateral line on many fish
No scales behind the head and pectoral area pattern of Spanish mackerel; body is round, not flattened
Small finlets behind the second dorsal and anal fins, mackerel-style
Look-alike: Spanish mackerel (Atlantic/Gulf) carry clean golden spots; Pacific mackerel show the wavy barred back

Habits

Travels in large surface schools that ripple the water — 'mackerel boils' under working birds
The Pacific coast's universal baitfish: everything from yellowtail to marlin eats them
Irregular visitor in the north — big years flood Puget Sound and BC, lean years they vanish
Feeds on anchovies, krill and fish larvae, day and night

How to catch them

Sabiki jigging

Rig: Sabiki rig under a small weight or torpedo sinker, light rod

Bait/lure: Nothing needed — the hooks are dressed with tiny flies and skin

Key tip: Jig gently near the bottom of the school; a loaded sabiki of mackerel is a workout on its own.

Casting to boils

Rig: Light spinning rod, 1/2 oz metal jig

Bait/lure: Small metal jig in green/silver

Key tip: Match the hatch: when mackerel feed on krill, go tiny or go home.
