Saltwater · Year-round; best in spring and summer around piers and bays
Jacksmelt
Atherinopsis californiensis
The largest silverside on the Pacific coast, a green-backed, silver-striped schooling fish of piers, bays and surf. It is a beginner staple on sabiki rigs and tiny baits, and anglers check the flesh carefully before eating because the fish often carry small worms.

Where they live
How to catch them
Sabiki fishing from piers and jetties Shore
Rig: Sabiki rig of tiny flies on size 8-12 hooks under a small float or with a light sinker, from piers and jetties
Bait/lure: Sabiki flies, tipped with tiny shrimp pieces if needed
Key tip: Work the rig slowly through bait balls and watch for the rod tip to load up with several fish.
Float fishing with pea-sized baits Shore
Rig: Light spinning tackle, small float and size 8-10 hook fished around bait balls and pier edges
Bait/lure: Pea-sized shrimp or bread pieces
Key tip: Keep baits truly tiny and near the surface — jacksmelt feed up in the water on small items.
