White SeabreamThe sargo or white seabream (Diplodus sargus) is a species of seabream native to the eastern Atlantic and western Indian Oceans. It is found from the Bay of Biscay southwards to South Africa, including Madeira and the Canary Islands, the Mediterranean, and (rarely) the Black Sea.
The sargo is a large, laterally-compressed fish with an oval shape. It has relatively large eyes and its body color varies from gray to brownish green. This species can reach in total length, but most do not exceed. The maximum recorded weight for this species is. The mouth is rather small in relation to body size. The scales are ctenoid and adherent, except near the dorsal fin where they are absent.
It is a fast swimmer and feeds on fishes and invertebrates. Spawning takes place between June and October on sandy beaches with strong surf. The eggs measure about. It rarely forms schools, but usually occurs in small groups, between two and 10 individuals.
The sargo is a carnivorous, demersal fish. It feeds on benthic invertebrates such as crustaceans and mollusks, by opening shellfish with its strong beak-like jaws. This species prefers sandy or stony substrate with rocky coastlines in order to feed. Its diet consists mainly of crabs, lobsters, and other crustaceans (including Peneidae species), gastropods (mainly Muricidae species), and polychaetes.
The sargo has a long and slightly compressed body covered with small scales and is greyish. The mouth is oblique and reaches almost to the eye, which distinguishes it from the very similar garfish (Belone belone), whose mouth does not reach so far back (although this distinction can be difficult to make when both fish are adult). The sargo lacks an air bladder. The maximum total length of the sargo is 70 cm, but a more typical adult size is around 45 cm.
This fish feeds on other fish and invertebrates such as prawns, crabs, and mollusks. It also eats plankton which it gleans off the surface of the water. The major predator of the sargo is humans, who mostly catch them when they are spawning (spring and summer). Sargos are found in temperate coastal waters in the eastern Atlantic Ocean. They prefer rocky shorelines or seagrass beds at depths up to 200 m.
The red porgy, Pagrus pagrus, is a species of marine fish in the family Sparidae. It is widespread throughout the Mediterranean Sea and the eastern Atlantic Ocean from Cape Blanc in Mauritania to Madeira Islands including the Canary Islands, Azores, and the westernmost part of the Mediterranean Sea (Laconia, Greece). The red porgy can grow up to a maximum length of 37 cm. It is usually found at depths of 100 m, where it can form large schools that are often associated with jellyfish. This species feeds on plankton which it sucks from the surface of the water just below.
The red porgy is fished commercially throughout its range, but yields have decreased in recent years. It is also considered an excellent game fish and is prized as a food fish due to its sweet white flesh.
