Longstriped Blenny
Parablennius rouxi
The Longstriped Blenny (Parablennius rouxi) is a small, benthic marine blenny of rocky coastal habitats. It is typically associated with shallow algal-covered reefs and crevices, where it rests on the bottom and picks at tiny invertebrates and algae.
Identification points
- Long, slender body with a continuous low dorsal fin
- Dark lengthwise striping along the sides
- Small blunt head with a short snout and relatively large pectoral fins
Habitat
Shallow rocky shorelines, breakwaters, tide pools, and reef edges with algal growth; usually close to the bottom in crevices and among stones in the nearshore marine zone.
Bait notes
Not a common sport fish; if targeted, tiny pieces of shrimp, clam, or marine worms on very small hooks can draw bites. Small soft-plastic grubs and micro jigs can also work around rocks.
Behavior
A territorial bottom-dweller that perches on rocks and darts between cover. It grazes on small crustaceans, worms, and algae, feeding mostly by day and staying close to shelter.
Caution
Avoid handling around rocks and tide zones where slips and cuts are common; blennies have small spines and can bite lightly. Check local regulations if taking any marine fish, and avoid eating unless local guidance confirms it is safe and lawful.
Fishing notes
Fish slowly near rocky structure with ultralight tackle and minimal weight. Present bait right in crevices or along the bottom; this species is best treated as a curiosity catch rather than a target.
