Histological, morphological, genetic, and phylogenetic analyses of a Cryptosporidium molnari-like isolate from a guppy (Poecilia reticulata) identified stages consistent with those of C. molnari and revealed that C. molnari is genetically very distinct from all other species of Cryptosporidium. This study represents the first genetic characterization of C. molnari.

OBJECTIVE To evaluate the efficacy of fish as predators of the Aedes aegypti larvae in laboratory conditions. METHODS The male and female of five different fish were included in the experiment. The tests to measure their consumption ability lasted five weeks for each species. Each trial involved four test tanks and four control tanks. Two control tanks contained just one fish, and the other t...

The reproductive response on the fecundity of ornamental fish guppy (Poecilia reticulata) indicates that the 0.01% concentration of natrum muriaticum 30 c potency is more significant than other concentrations. It was suggested that 0.01% concentration enhance the fecundity and increase the production of guppy.

Environmental monitoring is a recent world-wide approach to save the future in line. The present study focuses on toxicity of heavy metals and pesticides freshwater aquarium fish (Poecilia reticulata Poecilia sphenops). intense drawing acute chronic safe levels pesticide exposed 96 h 28 day respectively. On exposure, were observed be under stress showed excitability. It was that both species hi...
