Mullet Fish: Characteristics and Habitat

Mullet fish are a type of ray-finned fish found in coastal temperate and tropical waters worldwide. There are approximately 78 species of mullet fish in 20 genera, and they have served as an important source of food in Mediterranean Europe since Roman times. Mullet fish have strong, muscular bodies and make a firm fillet. They are oily fish and have a stronger taste than some milder varieties.

Mullet fish have elongate and robust bodies with flattened and broad heads. Their eyes are covered by well-developed transparent fatty eyelids, and their mouths are small with thin lips and open at the front, having a knob at the front of their lower lips. Mullets are characterized by their small, triangular mouths, the lack of a lateral line, and two separate dorsal fins. They are a commercially valuable schooling fish found throughout tropical and temperate regions, generally inhabiting saltwater or brackish water and frequenting shallow, inshore areas.

Biology and Species

Anatomy and Appearance

Mullet fish, belonging to the family Mugilidae, are ray-finned fish with a streamlined body shape. They have two dorsal fins, with the first one being larger than the second. Mullet fish also have a lateral line system, which helps them detect movement and vibrations in the water. Their scales are small and thin, making them difficult to remove when cleaning the fish.

Mullet fish have a silver-grey colouration, with some species having a reddish tint. They can grow up to 1 metre in length and weigh up to 5 kilograms. Their pectoral fins are large and fan-like, allowing them to swim efficiently in coastal waters.

Habitat and Distribution

Mullet fish can be found in a variety of environments, including tropical, temperate, freshwater and brackish water. They are commonly found in coastal waters of the Atlantic Ocean, Mediterranean Sea and Black Sea. Some species of mullet fish are also found in freshwater rivers and lakes.

Diet and Feeding Habits

Mullet fish are omnivores, feeding on a variety of food sources including algae, detritus, plankton and vegetation. They use their large pectoral fins to stir up the sediment at the bottom of the water, exposing food sources that they can then feed on. Mullet fish are also known to feed on small crustaceans and molluscs.
