Biology

Adults form small shoals in midwater above or near rocky reefs or above seagrass meadows (Posidonia. They feed on small planktonic or benthic animals (Ref. 6760). Reproduce in summer (Ref. 6760). Eggs characterized by adhesive filaments are nested on rocky or sandy bottoms (Ref. 6760). Males guard the eggs (Ref. 6760).

Chromis chromis

Damselfish (Chromis chromis) is a small Chromis fish from the Eastern Atlantic and Mediterranean.

Description[edit]

It grows to a size of 25 cm in length, with common length of 13 cm.

The body is oval, deep, laterally flattened. Very young specimens are brilliant iridescent blue in color, young specimens have blue stripes and dorsal and anal fins outlined with blue stripe, while adults are dark brown-blueish.

The head is short and fully scaled with large eyes. There is a single nostril on each side. The mouth is small, protractile; jaws are equipped with small teeth in three rows.

It feeds on small planktonic animals and benthic algae - the main food components are Copepoda, Appendicularia, Cladocera, Gastropod larvae, Bivalve larvae, fish eggs and fish larvae.

Spawning depends on location, but it occurs during Summer.

It occasionally makes its way into the aquarium trade.

Distribution and Habitat[edit]

It occurs in the Mediterranean and Eastern Atlantic, from Portugal to Angola.

Chromis chromis inhabits littoral, mainly in rocky areas from 2 to 40 m depth, in small shoals in midwater above or near rocky reefs and above sea-grass meadows.

Fishing[edit]

Due to small size Chromis Chromis has minor role in commercial fishing. As a game fish, it is often caught during the day on light tackle. Small hooks are baited with bread, pasta, small chunks of fish, mussels, worms, small prawns etc.

It can be caught in fish traps and nets. Due to small size, it is rarely caught with a speargun.

Cuisine[edit]

White meat is soft, tender, very tasty. Unfortunately, due to small size, it is mostly pan fried. Boiled with other small fish makes great fish soup. Larger specimen are prepared as part of mixed fish stew.
