Hoplias malabaricus Bloch, 1794 is one of the fish species most commonly found in the micro-region ponds of Cariri in Paraíba; however there are no studies in the region on its parasitic fauna. Due to this, the study aimed to characterize the ectoparasitologic fauna, blood profile and histopathological findings of the gills of H. malabaricus from four ponds in Sumé/PB. At each pond 10 specimens were captured and limnological water analysis was performed as the biometrics of specimens and blood samples were collected by caudal venipuncture. Parasite collection methods were used according to literature recommendations. Also gill samples were collected for histopathological assessment. Comparison of the averages were made by Tukey test at a probability of 5%. The results show that H. malabaricus ectoparasite fauna from ponds located in Sumé/PB is diverse, once various ectoparasites taxons are identified on body surface and gills. The parasitic fauna promoted hematological and histopathological changes in the gills. The results show also an epibiosis relationship of Epistylis sp. with Lernaea cyprinacea and branchiurans crustaceans on H. malabaricus. |
