Observations on Ceratothoa verrucosa (Isopoda: Cymothoidae) parasitic on sparid fishes from central Japan, with the third record of the isopod from crimson seabream, Evynnis tumifrons

Kazuya Nagasawa and Makoto Okada

Abstract / Introduction / Summary:

Specimens of Ceratothoa verrucosa (Schioedte and Meinert, 1883) were collected from the buccal cavity of a red seabream, Pagrus major (Temminck and Schlegel, 1843), and a crimson seabream, Evynnis tumifrons (Temminck and Schlegel, 1843), in coastal waters of the Northwestern Pacific Ocean off Mie Prefecture, central Japan. The collection of C. verrucosa from E. tumifrons represents its third record from the fish species. Based on the present and previous records of C. verrucosa from Japan, it is likely that, in addition to P. major, sparids of the genus Evinnis also serve as significant hosts for the isopod.
