Yellowmouth Barracuda to Calafuria Reef

Rates: 3

Sphyraena viridensis, the yellowmouth barracuda or yellow barracuda is a predatory ray finned fish from the family Sphyraenidae, the barracudas, which is found in the warmer waters of the western Atlantic Ocean and the Mediterranean Sea. It is often confused with the European barracuda Sphyraena sphyraena. Barracuda a Calafuria Sphyraena viridensis

The exact distribution of Sphyraena viridensis is unclear because of confusion with S. sphyraena. It occurs in the eastern central Atlantic around the Azores,Madeira,Cape Verde Islands and the Canary Islands and has been recorded in the eastern Mediterranean off Lebanon. It has also been recorded in the Mediterranean in the Adriatic Sea,Aegean Sea, off Israel, Algeria, Corsica and Sicily.

In summer they form schools of up to 180 fish, although most schools number 30-40 fish, in areas where there are strong currents. These schools are predominantly made up of sub-adult fish with the smaller fish nearer to the surface and the larger, usually female, fish at the bottom of the school at depths of up to 30m. In winter the only aggregations are small groups of juveniles in shallow bays. No territorial behaviour was observed. Schooling is thought to be an anti predator defence and to facilitate mating with the smaller males being attracted to the larger females, in addition groups of barracudas were more successful in hunting prey fish than single fish. This species does not appear to mix with other barracuda species in mixed schools.

Sphyraena viridensis is landed in small quantities in the eastern Mediterranean by fishermen using in trammel-nets and beach-seines. It has been reported from markets in Turkey but it is generally caught as a bycatch, although as numbers increase in the Mediterranean it may be becoming a more important species for fisheries.

The Great Barracuda (Sphyraena barracuda), also known as the Giant Barracuda, is present in tropical to warm temperate waters, in subtropical parts of the Indian, Red Sea, Pacific and Atlantic oceans, from mangrove areas to deep reef, with a lower depth limit of 110 meters.
