Popis: Little is known about elasmobranches in Pakistan despite their enormous diversity, commercial value and export earning adding into nation’s economy. In this study, preliminary data was gathered and document some observations on elasmobranches and their current state. Some regular observations have been made between 2015-2016 at monthly intervals for two key landing centers, the Karachi Harbour and Ibrahim Hyderi Fish Center. Specimens of small elasmobranches transported to the laboratory, whereas, larger specimens of more than 100cm TL were identified and measured at the Harbour. It was noted that family Carcharhinidae (grey sharks) locally called as “mangra” found in substantial amounts during winter and consistently landed throughout the year. Family Dasyatidae (batoid fishes) known as “pitten” in local dialect was in sufficient amount during summer whereas lower catches appeared in winter. Among guitar fishes Family Rhinobatidae most abundant family was found in the winter catches and the lowest in summer months. This study was aimed to evaluate potential of common elasmo branch species and gather data on abundance, seasonal variation and morphometry. It is expected that this baseline data would help biologists and conservatives for further investigation on elasmobranches in the area.
