Factor and multiple regression analysis were used to extract the morphometric variables that contributed to feeding success in three small freshwater fishes. Of the first two factors, factor 1, showed high loading of gut weight (GW), length of the upper (UJ), and lower jaws (LJ) in mola, Amblypharyngodon mola (Hamilton), and GW and vertical mouth opening (VMO) in punti, Puntius ticto (Hamilton)...

Sunto Dopo una breve introduzione delle principali idee della topologia formale [Sam87] vengono introdotte le nozioni di punto e co-punto. Si presentano quindi alcuni metodi per costruire punti e co-punti in opportune topologie formali e si forniscono alcune applicazioni logiche di tali costruzioni 1 .

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...

Freshwater lakes are sensitive ecosystem and respond to the episodic changes from its surrounding environment. The physico-chemical factors of water and biological processes determine the quality of water which in turn indicates the diversity of fauna and flora that the water would support. However, the ecological factors of lake correlating with parasitic isopods under natural conditions are p...

Abstract Spatiotemporal variation in fish assemblage structure was conducted from January to December 2015 in order to know the impacts of sanctuary on ichthyo-faunal diversity with its indices and major hydrological factors from six sampling stations of Karatoya fish sanctuary sectioned in the river Karatoya. A total of 69 fish species was obtained from this sanctuary including 21 threatened ...
