Dussumier's Rockskipper

Istiblennius dussumieri

Dussumier's Rockskipper (Istiblennius dussumieri) is a small tropical blenny that lives on wave-washed rocky shores. It clings to rocks in the intertidal zone and is usually of little angling interest.

Upper intertidal rocky reefs, tide pools, surge channels, and shallow shoreline rocks exposed to heavy wave action in tropical Indo-Pacific coasts.

Замітки про наживку

Not a targeted game fish; if caught at all, small bits of shrimp, clam, or fish skin may take it on very light tackle. Tiny soft lures or bits of bait worked near rocks can produce incidental takes.

Поведінка

A benthic grazer that feeds mainly on algae and tiny invertebrates scraped from rock surfaces. It stays close to crevices and rock faces, darting between cover in the wash zone.

Обережно

Use caution on slippery wave-washed rocks; the species is small and not a food fish in most fisheries, so it is generally not targeted for consumption.

Рибальські нотатки

Best viewed or sampled around low tide on exposed rocks rather than pursued as sport. If attempting capture, use very light hand nets or micro tackle near surge edges and release quickly to avoid stress.
