The Impact of Tin Mining Activities on Squid (Uroteuthis chinensis) Fishing Ground In South Bangka

Abstract

The Region of tin mining activities in the waters of South Bangka was also the squid fishing ground activities for fishermen. The waste of tin mining activities generates waste that directly disposes into waters that may affect the water quality. Water quality parameters include temperature, brightness, salinity, dissolved oxygen, flow, depth, heavy metal content of sea water and plankton. The waste from mining activities that are directly disposed into the waters generally containing heavy metals Pb and Fe. The purpose of this study was to determine the effect of waste tin mining activities on the squid fishing ground in the waters of South Bangka Regency. The method used in this research is descriptive method. Sampling point was determined in accordance with the squid fishing area as much as 18 points in the tin mining areas and 18 points outside the tin mining area. The content of heavy metals Pb and Fe on sea water of tin mining area is higher than outside of tin mining area.The average value of Pb and Fe in sea water mining activity areas was higher which is equal to 0,11 mg/land 0,31 mg/l compared with the outside of tin mining area which was equal
