Effect of recent flood on icthyoplankton and juvenile fish assemblage changes in Kuantan river revealed through DNA barcoding

Identifying early life stages of fishes to the species level is one of the challenging task for the taxonomist as the information on key morphological characters are overlapping between genetically closer individuals. Universal DNA barcode (cytochrome oxidase C subunit 1) gene sequence helped tremen...
