fecundity of the hypostomus affinis (siluriformes, loricariidae) in the lajes reservoir, rio de janeiro, brazil.	the armored catfish hypostomus affinis is a widespread loricariidae fish in the lajes reservoir (22 degrees 42'-22 degrees 50' s; 43 degrees 53'-44 degrees 05' w), the largest lentic environment in the rio de janeiro state, but little is known about their reproductive biology. one hundred and twenty five females, captured from january 1996 to december 1997, were used to assess ovarian development (29 were used to determine fecundity). the oocyte distribution by size-diameter classes revealed the ...	2002	12298245
community ecology of the metazoan parasites of white sea catfish, netuma barba (osteichthyes: ariidae), from the coastal zone of the state of rio de janeiro, brazil.	between march 2000 and april 2001, 63 specimens of n. barba from angra dos reis, coastal zone of the state of rio de janeiro (23 degrees 0' s, 44 degrees 19' w), brazil, were necropsied to study their infracommunities of metazoan parasites. fifteen species of metazoan parasites were collected: 2 digeneans, 1 monogenean, 2 cestodes, 1 acantocephalan, 2 nematodes, 6 copepods, and 1 hirudinean. ninety-six percent of the catfishes were parasitized by at least one metazoan parasite species. a total o ...	2004	15195376
ectoparasites as numerical dominant species in parasite community of trachelyopterus striatulus (siluriformes: auchenipteridae) from guandu river, southeastern brazil.	sixty specimens of singing catfish trachelyopterus striatulus (steindachner, 1877) (siluriformes: auchenipteridae) collected from guandu river (22º 48' 32" s and 43º 37' 35" w), in the state of rio de janeiro, brazil from october 2006 to march 2009, were necropsied to study their parasites. from the 60 specimens of t. striatulus examined 57 were parasitised by at least one parasite species. the majority of the parasite specimens collected were monogeneans followed by nematoda, digenea and hirudi ...	2011	21881785
Monitoring water quality in reservoirs for human supply through multi-biomarker evaluation in tropical fish.	Paraíba do Sul River is located at a very densely inhabited region of Brazil crossing the three most industrialized states of the country (São Paulo, Minas Gerais and Rio de Janeiro states). As a result, industrial and farming residues as well as urban sewage are frequently disposed without appropriate treatment. The current study aimed at investigating the water quality in three reservoirs along the Paraíba do Sul River (Ilha dos Pombos, Santa Cecília and Santa Branca), through physiological, m ...	2011	22179394
new morphological data and first description of gravid female of cucullanus bagre petter, 1974 (seuratoidea: cucullanidae) from bagre bagre (linnaeus, 1766) (siluriformes: ariidae) off brazil.	cucullanus bagre petter, 1974 (cucullanidae) is redescribed based on the examination of newly collected material and the revaluation of type specimens, using light and for the first time scanning electron microscopy. parasite specimens were collected from the intestine of the coco sea catfish bagre bagre (linnaeus) (ariidae) off the south atlantic coast, state of rio de janeiro, brazil. detailed morphological analysis revealed the presence of an unpaired papilla just anterior to the cloacal prot ...	2014	26204032
