Tub gurnard
Tub Gurnard[edit | edit source]
The tub gurnard (Chelidonichthys lucerna) is a species of marine fish belonging to the family Triglidae, commonly known as the gurnards or sea robins. This species is notable for its vibrant coloration and the ability to produce sounds using its swim bladder.
Description[edit | edit source]
The tub gurnard is characterized by its bright red or orange body, which can sometimes appear pinkish. It has a large, bony head with a distinctive "helmet" appearance, and its body tapers towards the tail. The pectoral fins are large and fan-like, often with a striking blue edge. These fins are used for "walking" along the seabed and for detecting prey.
Distribution and Habitat[edit | edit source]
The tub gurnard is found in the eastern Atlantic Ocean, from Norway and Iceland down to West Africa, including the Mediterranean Sea and the Black Sea. It inhabits sandy and muddy substrates on the continental shelf, typically at depths ranging from 20 to 300 meters.
Behavior[edit | edit source]
Tub gurnards are benthic feeders, using their specialized pectoral fins to "walk" along the seabed and sense prey. They primarily feed on crustaceans, mollusks, and small fish. The species is known for its ability to produce a drumming sound, which is thought to be used in communication and during spawning.
Reproduction[edit | edit source]
Spawning occurs in the warmer months, with females laying eggs that are pelagic, meaning they float in the water column. The larvae are planktonic and undergo several developmental stages before settling to the bottom as juveniles.
Culinary Use[edit | edit source]
The tub gurnard is considered a good eating fish, with firm, white flesh. It is often used in Mediterranean cuisine, where it is prepared in various ways, including grilling, baking, and frying.
Conservation[edit | edit source]
Currently, the tub gurnard is not considered to be at risk of extinction. However, like many marine species, it is subject to pressures from overfishing and habitat degradation.
