Perbandingan Kelimpahan Ikan Karang Pada Fish Shelter Di Karang Melantut Pantai Rebo Dan Pantai Matras Kecamatan Sungailiat, Kabupaten Bangka

Comparison Of Coral Fish Abundance Fish Shelter in Karang Melantut Rebo Beach and Matras Beach Sungailiat District, Bangka Regency

Abstract

Tin mining activities carried out on the waters of Bangka Island have a negative impact on coral reef ecosystems, it is necessary to rehabilitate coral reef ecosystems such as sinking fish shelters in these waters, so that can provide new habitat for reef fish. The purpose of this study is to see the comparison of the abundance of reef fish in fish shelter in the waters of Karang Melantut Rebo Beach and Matras Sungailiat Beach. This research was conducted in March and April 2019, using the visual census method. The results of the study mention the presence of reef fish species found in both locations of fish shelter is 32 species from 12 families. The abundance of reef fish that is most commonly found in both locations is there are 214 individuals on Matras Beach in March. While the least of reef fish abundance was found in Karang Melantut on Rebo Beach in April is 90 individuals. This is due to the sinking time of fish shelter at Matras Beach earlier and the characteristics of sinking fish shelter location on Matras Beach far from the coral reef ecosystem. So that can be concluded that fish shelter sinking activities can solve the mining activities who have a negative impact on coral reefs.
