Genetic and morphologic variation, haplotype relationships, and structuring of populations within Puntius denisonii and its close related species Puntius chalakkudiensis have been tested using molecular and biometric data, to infer phylogeographic patterns. Sequences of mitochondrial DNA ATPase 8 and 6 genes, and morphometric data, were used to find population structuring. Specimens were collec...

studies on the biometric parameters of a species to have an important role in its population or stock management and conservation. present study investigated the morphometric, meristic, length-weight relation (lwrs), length-length relation (llrs) and growth status (k and kn) of the redline torpedo barb, p. denisonii collected during august 2012 to july 2013 from river valapattanam, kerala. the ...

While the collection of fish for the aquarium pet trade has been flagged as a major threat to wild populations, this link is tenuous for the unregulated wild collection of endemic species because of the lack of quantitative data. In this paper, we examine the extent and magnitude of collection and trade of endemic and threatened freshwater fishes from India for the pet markets, and discuss thei...

Present study was designed and an attempt has been made to study the Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray spectroscopy (EDAX) of fish of genus Puntius from Uttarakhand. Puntius conchonius and Puntius sophore (Spotted barbs) in the fast flowing water of Song River. The body of the fish in laterally compressed and is covered over by numerous small scales. The number of l...

the tropical asian cyprinid genus puntius is a major part of the ichthyofauna in southeast asia. systematic status of the genus puntius among cyprinidae, the most prominent freshwater fish all over the world, remain to be substantiated. the molecular phylogenetic analyses derived from recombination activating genesequences (rag2) for 35 representative samples of malaysian puntius and their alli...
