| new hosts and genetic diversity of flavobacterium columnare isolated from brazilian native species and nile tilapia. | flavobacterium columnare is responsible for disease outbreaks in freshwater fish farms. several brazilian native fish have been commercially exploited or studied for aquaculture purposes, including amazon catfish leiarius marmoratus × pseudoplatystoma fasciatum and pacamã lophiosilurus alexandri. this study aimed to identify the aetiology of disease outbreaks in amazon catfish and pacamã hatcheries and to address the genetic diversity of f. columnare isolates obtained from diseased fish. two out ... | 2015 | 26575151 |
| first record of non-native hybrid catfish pseudoplatystoma reticulatum × leiarius marmoratus in the upper paraná river basin, brazil. | the aim of this study is to report the presence of a three non-native hybrid long-whiskered catfishes (family pimelodidae) in the upper paraná river basin, brazil. genetic analyses demonstrated that the three presumptive hybrids were a result of the crossbreeding of pseudoplatystoma reticulatum (central amazonas river basin and lower paraná river) and leiarius marmoratus (amazonas, essequibo and orinoco rivers), producing a hybrid commonly known in brazil as cachandiá. the potential threat to bi ... | 2018 | 29194600 |
