Morphological discriminations of arius species (siluriformes: ariidae) in Peninsular Malaysia using Truss network approach

Ariid catfishes, belongs to family Ariidae is considered as one of the taxonomically problematic group and still under review by fish taxonomist globally. A vigilant and detail observation is important during the species level identification of ariids. Therefore, this study was carried out to determ...
