The fishes was measuring as for standard length, analyzing the musculature and adjacent abdominal serose in a “candling table” after filleted the samples. Just was founded parasitism for plerocercoids of cestode Trypanorhynch. The blastocysts captured were observed among of morphology and size, the same was mading with the scolices when liberated. All the species of fishes studied were parasitizing, with 16% in M. ancylodon, 77,78% in A. proops, 79,17% in C. virescens and 82% in C. acoupa, reaching an overall frequency to 61,71% (108 specimens) and an intensity of infection average about six blastocysts per fish. The parasitizing species, as well as frequency of infection, were as follows: Callitetrarhynchus gracilis (52,57%), Pterobothrium heteracanthum (13,71%), Poecilancistrium caryophyllum (12%) e Pterobothrium crassicolle (3,43%). Between infested fishes, 85,19% presented occurrence in the abdominal region (abdominal musculature and serose) and 81,48% muscular involvement (abdominal e body musculature). The specie P. heteracanthum showed preference to infect the abdominal region of fishes and the specie P. caryophyllum the musculature. There was significative association (P < 0,01) between the species of fishes analyzed and the frequency of infection.porAcesso AbertoPeixeIctioparasitologiaCestóidesInspeção de alimentosPescada amarelaCynoscion acoupaPescada-cambuçúCynoscion virescensPescadinha-góMacrodon ancylodonHelmintoBelém - PAPará - EstadoAmazônia brasileiraDissertaçãoCNPQ::CIENCIAS AGRARIAS::CIENCIA E TECNOLOGIA DE ALIMENTOS::CIENCIA DE ALIMENTOS::AVALIACAO E CONTROLE DE QUALIDADE DE ALIMENTOS
