Habitat around Los Angeles

Surface and mid-water around piers and jetties, especially on a moving tide.

How LA anglers actually fish them

No bag limit, no size minimum (T14 CCR §27.60(b)). A small hook under a float with a scrap of squid covers it. Around LA they are a pier and harbor fish, not a Central Coast surf-smelt net fishery.

Identification

Jacksmelt (Atherinopsis californiensis) are long, slender silversides with a bright silver stripe along the side and a bluish-green back. They are the largest local silverside, regularly reaching a foot or more. Topsmelt look similar but are smaller, and grunion are much smaller still.

Habitat

Jacksmelt school near the surface around piers, jetties and harbors. Shoreline Village and the other Long Beach piers, Santa Monica and the South Bay piers all see them.

Season

Present year-round, with many pier anglers reporting good numbers in winter and spring.

Techniques

  • A float (bobber) rig with several small hooks just below the surface.
  • Bits of squid, shrimp, or bread-like baits.
  • Sabiki rigs worked near the surface.
  • Light tackle; jacksmelt fight well for their size.

Jacksmelt are among the safer fish to eat from the LA coast. OEHHA's advisories for both LA coastal zones allow up to 4 servings a week for women 18–49 and children 1–17, and up to 7 servings a week for women 50+ and men.
