Abstract

Lernaea cyprinacea, a parasitic cyclopoid copepod, is found to parasitize Naujan White Goby, Glossogobius aureus (TL = 8–23 cm, BW = 8.6–101 g) maintained in concrete tanks for broodstock development. The infected fish displayed flashing behavior, localized redness, erosion of pectoral, dorsal, and caudal fins, and inflammation of the vent. Red sores were also found on the skin, buccal cavity, and muscle tissue. Sexually mature female G. aureus were seen to be more susceptible to L. cyprinacea than mature males. Lernaea infection was successfully controlled by a salt dip at 10 ppt for 2–3 minutes followed by the salt bath at 2–3 ppt for 21 days. This is the first record of L. cyprinacea infection in captive G. aureus in the Philippines.
