Abstract

Marine fish community is very sensitive to environmental changes. So the number of species, abundance, and biodiversity index can be used as a reference to assess the quality of the aquatic environment. The aim of this study was to describe fish biodiversity in Belitung Timur, Bangka Belitung Islands, Indonesia. Three islands were visited i.e. Pekandis Island, and Keran Island, Gosong Semut (Gosong refers to sandbar) for reef fish survey and for the economical fish study we also visited fisheries landing sites (i.e. Teluk Pering, Tanjung Batu Pulas, and Pantai Burung Mandi). The underwater visual census was used for in situ surveys of reef fish, and the fish species landed in fisheries landing site also been checked. Forty-two families of economical fish that had been landed by local fishermen were identified, and ten families of reef fish were found in reef systems of research location. A total of 10 families were recorded from three islands in Belitung Timur Regency. In addition, 42 families of commercial fish were also observed in fish landing sites from the coastline of Belitung Timur Regency, Bangka Belitung Islands.

Abstract

Blue swimmer crab (Portunus pelagicus) are not only tasty and popular, these animals are the producers of hard shell to protect their body. From its shell waste, we can harvest chitin and process it into chitosan. As blue swimmer crabs waste is easily found in Bangka, we hope that it can be used to solve water pollution caused by heavy metals (Pb, Zn, and Cu) in many open pit areas there. The objective of this study was to evaluate effectivity of blue swimmer crabs’ chitosan in adsorbing heavy metals. This study was conducted from May to December 2010 in Sungailiat. Contaminated water from ex-mining open pit was used in this study. A 0,5%, 1% and 1,5% of chitosan was applied in degrading heavy metal. Research showed that there was a decline of heavy metal content caused by chitosan application. Its adsorbing activity was influenced by pH and temperature. We can benefit from blue swimmer crabs waste shell to improve water quality in ex-mining open pit water.
