- Abstract
White mullet is a commercial fi h species abundant in the coastal waters of Brazil. This study investigated the occurrence of crustacean ectoparasites on white mullet, Mugil wrema captured from the littoral waters of Rio Grande do Norte tate, Brazil. From 2006 to 2007, 31 individuals of M. wrema were captured and encountered ectoparasites were observed, identified and counted. M. wrema wa parasitized by ectoparasitic crustacean , caligid copepods, Caligus bo11ito and Caligus sp.; ergasilid copepods, Ergasilus versicolor and E. lizae; and isopod Cymothoa spinipalpa. Of the caligids detected, 66.66% were C. bonito and 33.33% Caligus sp. C. bonito occurred on males of M. wrema during the drought season and Caligus sp. occurred on females during the rainy season. The prevalence of both caligid species was 3.23%. Of the ergasilids detected, E. versicolor (91.67%) occurred during the drought and rainy seasons, whereas E. lizae (8.33%) occurred during the rainy sea on. Prevalence of E. versicolor was 35.48% and E. lizae was 3.23%. C. spi11ipalpa was detected during the drought and rainy seasons with a prevalence of 16.13%. The preferred site of fixation by the parasites was the branchtal chambers.
