摘要: The present work studied helminth parasites of freshwater "corvina" Plagioscion squamosissimus from Volta Grande Reservoir, MG, Brazil. Sixty eight fishes with averages 25.2 cm length and 180.9 g weight were collected net, bimonthly December 1995 thru 1996. Parasites carefully removed their cysts that in the intestinal mesentery. Specimens fixed AFA 65°C preserved alcohol 70% 5% glicerine. In camera lucida 21 nematodes drawned after clarification acetic acid or Amann lactophenol. Nematode larvae identified as Thynnascaris sp. (Nematoda: Anisakidae). From examined 30 out 68 presented nematode a prevalence 44.1%. average number per host was 0.0 to 13.8 mean intensity 16.0. Statistical analysis according Fisher's Exact Test showed these infections dependent on pluviosity air temperature
