Northern Clingfish

Gobiesox maeandricus

Northern Clingfish (Gobiesox maeandricus) is a tiny intertidal clingfish of the northeastern Pacific, often found tight to rocks in surge-swept tidepools. It uses a suction disc to hold on in heavy wave action and is usually encountered more by turning rocks than by targeted angling.

Identification points

  • Small, flattened body with a wide head and large pectoral fins
  • Prominent suction disc formed from the pelvic fins on the underside
  • Mottled brown to olive coloration that matches rock and algae, with no obvious scales

Habitat

Rocky intertidal zone, surge channels, and tidepools on exposed coasts; clings to boulders, kelp holdfasts, and algae-covered rock in very shallow water.

Bait notes

Not a typical game fish and usually too small to target intentionally. If encountered while tidepooling, tiny bits of shrimp, amphipods, or worms may take it, but catch-and-release is the norm.

Behavior

A cryptic bottom-hugger that uses its suction disc to resist surf and hide under rocks and in crevices. It feeds on small benthic invertebrates and is mostly active in intertidal cover rather than open-water roaming.

Caution

Handle carefully: small intertidal fishes are easily damaged and should be returned quickly. Check local tidepool and marine reserve rules, as collection may be restricted in some areas.

Fishing notes

Fishing is generally impractical and often inappropriate in tidepools; most captures are incidental while collecting bait or turning rocks. If legally taken, use very light tackle and release immediately to avoid stress.
