- Abstract
This study determines the fish diversity of high altitude small streams and ponds in Chalet Pak Lah, Janda Baik, Pahang. Fish were collected using fish electro-shocker, fishing rods and scoop nets from 20th to 21st October 2017. A total of six families and 11 species were recorded, including Hemibagrus gracilis, Barbodes banksi, C. lucius, Oreochromis niloticus, Clarias leiacanthus, Barbodes banksi, B. lateristriga, Neolissochilus soroides, Poropuntius normani, Rasbora elegans and Glyptothorax schmidti . Streams recorded a high number of individual fish with 82, compared to ponds with only seven individuals. Moreover, the water dissolved oxygen was significantly lower in ponds compared to the streams, but the water conductivity and TDS significantly lower in the streams. The indices for fish diversity and richness were higher in streams, but lower for evenness. This study indicates that moderate number of fish species was observed in this high altitude habitats, but the occurrence of introduced fish such as O. niloticus might threaten the native fish diversity of the area in the future.
