| structure of the parasites communities in two erythrinidae fish from amazon river system (brazil). | this study compared the parasite communities of hoplias malabaricus and hoplerythrinus unitaeniatus from amazon river system. hoplias malabaricus were infected by ichthyophthirius multifiliis, piscinoodinium pillulare, tetrahymena sp., urocleidoides eremitus, braga patagonica, metacercariae of clinostomum marginatum, procamallanus (spirocamallanus) inopinatus, larvae of contracaecum sp. and larvae of nomimoscolex matogrossensis. hoplerythrinus unitaeniatus were also infected by these same specie ... | 2015 | 26083690 |
| seasonal pattern in parasite infracommunities of hoplerythrinus unitaeniatus and hoplias malabaricus (actinopterygii: erythrinidae) from the brazilian amazon. | the present study investigated the effects of seasonal variation in parasites infracommunities of hoplerythrinus unitaeniatus and hoplias malabaricus from a tributary of amazon river. for h. unitaeniatus and h. malabaricus, 11 parasite species were similar, and greatest parasite richness occurred during the rainy season. ichthyophthirius multifiliis was the dominant parasite species for both hosts. in h. unitaeniatus, infection by whittingtonocotyle caetei, whittingtonocotyle jeju, urocleidoides ... | 2016 | 26751882 |
| spawning and parental care in hoplias malabaricus (teleostei, characiformes, erythrinidae) in the southern pantanal, brazil. | herein we describe spawning and egg guarding in the erythrinid fish hoplias malabaricus observed in the southern pantanal (19 degrees 34' s and 57 degrees 00' w), state of mato grosso do sul, brazil. nests were depressions built on sandy soil in flooded areas, and contained a mean of 8,197 +/- 2,204 eggs (n = 4); the mean diameter of eggs was 1.44 +/- 0.09 mm (n = 400). among 11 nests observed, eight were guarded by males and three by the pair. one male remained in the nest for six days, and two ... | 2006 | 16906301 |
