Cestóides da ordem Trypanorhyncha em peixes de importância comercial capturados no litoral amazônico

Abstract

The purpose of this study was to identify the parasite fauna, particularly the cestode Trypanorhyncha the order, which affects market value of fish caught in Amazon coastal and assess the possible impacts on fisheries production industry. We examined 328 samples of five species of fish: Cynoscion acoupa, Macrodon ancylodon, Plagioscion squanosissimus, Centropumus undecimalis, Arius Parkeri. It made the measurement of its total length and weighing fish, filleting in the regions examined body, muscles and serous. The blastocyst, Trypanorhyncha were removed and sent for laboratory Azevedo Carlos. All species surveyed were parasitized by Trypanorhyncha, totaling 283 (73.78%) parasitized copies. The species Callitetrarhynchus gracilis showed higher prevalence parasite. Poecilancistrium caryophyllum was the most infect the species of fish studied, followed by Pterobothrium crassicolle and Pterobothrium heteracanthum and Callitetrarhynchus speciosum, infected Cynoscion acoupa and Arius Parkeri respectively. The regions abdominal muscles and backside were the most affected.
