Saddled seabream – Oblada melanurus

The Saddled Seabream, scientifically known as Oblada melanurus, is a common fish species found in the Mediterranean Sea and the eastern Atlantic Ocean. It is a popular choice for both commercial and recreational fishing due to its palatable flesh. This fish is recognized for its distinctive saddle-like marking on its back, which gives it its common name.

Description & Characteristics

Oblada melanurus is a relatively small fish, with a maximum recorded size of 36.6 cm. It has a deep, compressed body with a prominent hump on the back and a small mouth. The most striking feature of the Saddled Seabream is the dark, saddle-shaped marking that extends across its back. This marking can be quite variable in size and intensity, depending on the individual fish. The body is generally silver in color, with a bluish tinge on the back. The fins are yellow-tinged, while the caudal fin is slightly forked.

Habitat and Occurrence

The Saddled Seabream primarily inhabits the Intertidal (Eulittoral) zone, the area between the high and low tide lines that experiences regular cycles of submersion and exposure. This zone is characterized by the alternation of low and high tides, creating a dynamic environment that the Oblada melanurus has adapted to. It is commonly found around rocky shores, reefs, and seagrass beds. The Saddled Seabream is a common sight in the Mediterranean Sea, where it is found in coastal waters and estuaries. It also occurs in the eastern Atlantic Ocean, extending as far north as the British Isles.

Taxonomy

Oblada melanurus belongs to the Class: Teleostei, Order: Eupercaria incertae sedis, and Family: Sparidae. This family, the Sparidae, is known as the sea bream family and includes a wide range of species known for their commercially valuable flesh and vibrant colors. The Teleostei, or bony fish, constitute the most diverse and successful group of vertebrates, comprising over 20,000 species.

Feeding

The Saddled Seabream is an opportunistic omnivore, feeding on a variety of small organisms. Its diet includes crustaceans such as brine shrimps and mysis, as well as small fish, algae, and other invertebrates. In captivity, Oblada melanurus can be fed with a variety of commercially available fish flakes and frozen foods, but larger varieties are preferred.
