Última Evaluation of the haematological parameters in Piaractus mesopotamicus Holmberg (Osteichthyes, Characidae) with Argulus sp. (Crustacea, Branchiura) infestation and treatment with organophosphate Zoologia Tavares-Dias,Marcos; Martins,Maurício Laterça; Kronka,Sérgio do Nascimento. Haematological parameters as erythrocytes, leukocytes and plasma glucose in Piaractus mesopotamicus Holmberg, 1887 were analyzed. Fish were parasitized with Argulus sp. (Crustacea, Branchiura) and treated with 0.4 mg of thriclorphon 500/L water. The effects of parasitism and the action of the treatment were evaluated. Parasitized fish showed greater number of monocytes (P>0.05) and special granulocitic cells (P<0.01) in the peripheric blood than the unparasitized (control) fish. Parasitized fish showed lower number of thrombocytes (P>0.05). Organophosphate treatment presented significantly reduction (P>0.05) in red blood cells (RBC) and hemoglobin.

Ano: 1999 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0101-81751999000200019 Parasitism by argulids (Crustacea: Branchiura) in piranhas (Osteichthyes: Serrasalmidae) captured in the Caiçara bays, upper Paraguay River, Pantanal, Mato Grosso state, Brazil Neotropical Ichthyology Fontana,Márcio; Takemoto,Ricardo Massato; Malta,José Celso de Oliveira; Mateus,Lúcia Aparecida de Fátima. In this study, 446 fishes were analyzed: 190 Pygocentrus nattereri, 193 Serrasalmus maculatus, and 63 S. marginatus.They were captured in two bays, upper and lower Caiçara, in the upper Paraguay River basin, during one hydrological cycle from May 2008 to April 2009. Six species of Branchiura were found: Dolops bidentata, D. longicauda, Dolops sp., Argulus multicolor, A. chicomendesi, and Dipteropeltis hirundo. All fish species were infested by more than one species of Branchiura and the overall prevalence was 33.4%. The following prevalences were observed: 52.6% in P. nattereri; 20.3% in S. maculatus, and 15.8% in S. marginatus. The relative condition factor (Kn) differed significantly between parasitized and non parasitized individuals only in P....
