Öktener* İstanbul Provencial Directorate of Agriculture, Directorate of Control, Aquaculture Office, Kumkapı, TR-34130 İstanbul, Turkey Abstract Pennella instructa Wilson, 1917 was reported on the cultured greater amberjack, Seriola dumerili (Risso, 1810) from the Mediterranean Sea of Turkey in October 2008. This parasite is reported for the first time from the greater amberjack. Parasite was recorded with a prevalence of 7.7 % and 2 the mean intensity on host. Introduction Their large size and mesoparasitic life have may be responsible for the cases of greater led to a number of studies of the Pennellidae. amberjack mortalities in (İskenderun Bay) the The most recent account and discussion of Mediterranean Coast of Turkey. their effects on the fish has been published by Kabata (1984). The genus Pennella Oken, This parasitological survey was carried out 1816 are amongst the largest of the parasitic with the aim of identifying the composition Copepoda, and except for a single species of the parasitic fauna of greater amberjack infecting the blubber and musculature of attempted in Turkey under farming systems, cetaceans, are found as adults embedded in so as to develop prevention and control the flesh of marine fish and mammals (Kabata, measures in advance of any possible outbreaks 1979). of infection. Economically, Seriola dumerili is one of the Material and Methods most important pelagic fish species in the Greater amberjack, Seriola dumerili (Risso, world, and initial attempts have been made 1810) (Teleostei: Carangidae) were bought to introduce the species into aquaculture from farming system in the Mediterranean systems.
