Marine leech Trachelobdella lubrica (Hirudinea: Piscicolidae) and Lernaeolophus sultanus (Copepoda: Pennellidae) parasitizing the black scorpionfish, Scorpaena porcus (Pisces, Scorpaenidae) from the eastern Adriatic Sea
During the ecological and biological survey of the black scorpionfish, Scorpaena porcus (Linnaeus, 1758) in the eastern Adriatic Sea, two unusual parasites were recorded: Trachelobdella lubrica (Grube, 1840) (Hirudinea: Piscicolidae) and Lernaeolophus sultanus (Milne-Edwards, 1864) (Copepoda: Pennellidae). The sampling was carried out in 2007-2008, and total of 711 black scorpionfish inhabiting coastal area from 1-30 m, were sampled by a trammel net. The black scorpionfish fish total length ranged from 10.2 to 26.4 cm. Parasites were isolated from fish above 16 cm of length. Infected fish did not carry more than a single parasite and were caught only during spring and autumn months. In both cases the infection rate did not exceed 0.9%. T. lubrica is an ectoparasite that lives mainly in the gill chambers of teleost fish species in warm, temperate and tropical seas around the world, most commonly emerging at low water temperatures. In October and December 2008, four T. lubrica specimens were found attached ventrally, at the base of pectoral fin of the host fish. The attachment sites showed light spherical rim of haemorrhages and swelling. Parasitic copepod L. sultanus, appears most frequently in the buccal or pharyngeal cavity of various marine fish, rarely on the fish body surface. It has been recorded from the Atlantic, Pacific and Indian Oceans as well as the Mediterranean. Specimens of L. sultanus were recorded only twice in the buccal cavity of the black scorpionfish specimens caught in June 2007 and December 2008. Parasite abdomen with outgrowths and egg-sacks protruded in the host mouth, while the cephalic part was burrowed deep into the fish tissue, causing strong inflammatory reaction. The present report represents the new host record for both parasites in the Adriatic Sea.
