The Shore Rockling (Gaidropsarus mediterraneus) can grow up to 35cm in length.

IdentificationEdit

A small brown elongate fish with three barbels on the head and an unusual first dorsal fin which consists of a single first ray followed by a fringe of vibrating rays set in a trench-like depression. There is no fin membrane between the rays in the first dorsal arrangement, but the second dorsal fin is conventional and runs the length of the body.

BreedingEdit

Summer

Habitat: In shallow water usually in rocky areas. Not so widespread as the similar species Ciliata mustela which is found in sand and rock areas.

FoodEdit

Small crustaceans and worms.

RangeEdit

Southern and western British coasts, Atlantic (Britain - Spain), Mediterranean.

Additional NotesEdit

Count the barbels to be sure of identification. Young are silver and live in the surface water, until autumn when they descend to the sea floor inshore and change colour to brown.

Other Rockling species occur including the much larger 3-Bearded Rockling, Gaidropsarus vulgaris.
