“…Fresh and mounted parasites were micrographed and measured with a digital sys- tem. Among the literature used for species identification: Bussieras (1972), Chisholm and Whittington (2007), Lamothe-Argumedo (1997), Palombi (1949) and Price (1939) for monogeneans; Ariola (1902), Guiart (1938), Ishii (1935), Legendre (1940), Pozdnyakov (1990), Pozdnyakov and Gibson (2008) and Yamaguti (1958Yamaguti ( , 1970 for didymozoids; Brian (1906), Hewitt (1969) and Kabata (1992) for copepods; Bruce (1983), Brusca and Iverson (1985), Haswell (1882) and Richardson (1905) for isopods. Prevalence (P%), range of intensity (IR) and mean intensity (MI) of each parasite species were calculated according to Bush et al (1997).…”
