A total of 96 fish, 75.9\u00a0\u00b1\u00a09.3% males and 88.9\u00a0\u00b1\u00a06.4% females, were parasitized by<jats:italic>Proteocephalus macrophallus<\/jats:italic>and<jats:italic>P. microscopicus<\/jats:italic>, with total mean intensities of 76.6\u00a0\u00b1\u00a023.9 and 145.2\u00a0\u00b1\u00a036.7, respectively, during this period. In the majority of the months analysed, males showed 71.4\u2013100% prevalence of parasitism and females 80\u2013100%. Although there was no significant difference, females showed a higher mean intensity of infection (145.2\u00a0\u00b1\u00a036.7) than males (76.6\u00a0\u00b1\u00a023.9). Fish weighing 300\u2013800\u00a0g showed a higher mean abundance of parasites (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.05) compared with the biggest specimens weighing 801\u20132750\u00a0g. Analysing both males and females together, the greatest mean intensities of infection were found in October and December (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.05) independent of the year, which coincides with the months of highest rainfall. These results show that fish living in reservoirs may be more susceptible to intermediate hosts than those that live in rivers.<\/jats:p>","DOI":"10.1017\/s0022149x10000830","type":"journal-article","created":{"date-parts":[[2011,1,6]],"date-time":"2011-01-06T04:39:04Z","timestamp":1294288744000},"page":"462-467","source":"Crossref","is-referenced-by-count":5,"title":["Infection levels of proteocephalidean cestodes in<i>Cichla piquiti<\/i>(Osteichthyes: Cichlidae) of the Volta Grande Reservoir, Minas Gerais, Brazil, relative to host body weight and gender"],"prefix":"10.1017","volume":"85","author":[{"given":"M.L.","family":"Martins","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"suffix":"Jr","given":"J.","family":"Pereira","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"de Chambrier","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.L.P.","family":"Mouri\u00f1o","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2011,1,6]]},"reference":[{"key":"S0022149X10000830_ref28","doi-asserted-by":"publisher","DOI":"10.2307\/3284522"},{"key":"S0022149X10000830_ref24","first-page":"301","article-title":"On the occurrence of endoparasitc helminthes in perch (Perca fluviatilis L.) from the M\u00e1cha lake fishpond system, Czechoslovakia","volume":"11","author":"Scholz","year":"1987","journal-title":"Acta Universitatis Carolinae \u2013 Biologica"},{"key":"S0022149X10000830_ref23","first-page":"675","volume-title":"CRC Handbook of tapeworm identification","author":"Schmidt","year":"1986"},{"key":"S0022149X10000830_ref19","doi-asserted-by":"publisher","DOI":"10.2307\/3283972"},{"key":"S0022149X10000830_ref16","doi-asserted-by":"publisher","DOI":"10.1017\/S0022149X0001419X"},{"key":"S0022149X10000830_ref14","first-page":"39","article-title":"Prevalence, intensity and seasonality of Ichthyouris voltagrandensis (Nematoda: Pharyngodonidae) in Myleus tiete (Osteichthyes: Characidae) from Volta Grande Reservoir, Minas Gerais, Brazil","volume":"29","author":"Martins","year":"2003","journal-title":"Boletim do Instituto de Pesca"},{"key":"S0022149X10000830_ref13","first-page":"210","article-title":"Ecological aspects of endohelminths parasitizing Cichla monoculus Spix, 1831 (Perciformes: Cichlidae) in the Paran\u00e1 River near Porto Rico, State of Paran\u00e1, Brazil","volume":"67","author":"Machado","year":"2000","journal-title":"Comparative Parasitology"},{"key":"S0022149X10000830_ref11","first-page":"279","article-title":"Comparative analysis of the communities of metazoan parasites of Orthopristis rubber and Haemulon stendachneri (Osteichthyes: Haemulidae) from the Southeastern Brazilian Littoral: I.
