Abstract

Abstract: The purpose of this study was to analyze and to describe the diversity and conservation status of fish in dam Rolak Songo which are located in Mojokerto District. Sampling of fish using gill nets was carried out during the dry and rainy seasons. Research result showed that in the dry season there were three species of fish, namely two endemic species of Brantas river ( Channa sriata and Barbonymous gonivatus ), and one exotic species ( Oreochompis mossambica ). While in the rainy season, we found four species of fish i.e Barbonymous gonivatus, Muysticus micronantus, Puntius bromoides (Brantas River endemic fish species), and Oreochompis mossambica (exotic fish species). Fish diversity in the water of Rolak Songo dam was low. Conservation status of these endemic fish ( C. sriata, B.gonivatus, M. micronantus, and P.bromoides ) is vulnerable (VU), while status of O. mossambica is least concern.
