The majority of coral reefs in Teluk Limau transplantation, Bangka dead. Death is presumed by cover sediments derived from marine mining.

Exploration Team Leader for the University of the Pacific Islands Coral Reef (UBB) Indra Ambalika say, 100 coral transplants planted in 2009.

"In October 2010 monitoring known four artificial reefs were dead. Coral reefs were covered with mud. The rest are still alive and began to concentrate against the cement blocks that are designed to transplant coral reefs," he said in Louth on Monday (2 / 5 / 2011).

However, UBB team pessimistic about the other reefs while monitoring the site in March 2011. At that time there are 17 ships and dozens of suction tin floating mines operating around the transplantation site. We were worried because the ships floating suction and mine was throwing tons of mining waste sludge. Ocean currents bringing mud into the planting site coral reefs, he said.

"Concern was evident in the monitoring of the Week (01/05/2011). Only two coral reefs to survive. Meanwhile, another 98 die because of mud. Coral reefs can not survive because the sediment sludge is too high. The water was too muddy and not suitable for growth. In fact, once we choose that location because of its ecosystem is still supportive. After the suction vessel in operation, the carrying capacity of ecosystems to shrink drastically, "he said.

While head of the Office of Marine Bangka Belitung Island Lewis said it was the impact of spatial ambiguity in the Pacific Islands. "Regulation of the spatial structure not being completed due to many factors discussed. There is no clear division of an area for what. So, open the possibility of all areas used for anything," he said.

Side has made an assessment of mining must operate a minimum of 1.5 miles of beach. Areas within a radius of 1.5 miles that are considered breeding grounds of fish. In addition, some fishermen also safer moves in the region.

However, many mining operations in the region was 1.5 miles. Floating mines at a distance of less than 200 meters from the beach can be seen in almost all the beaches on the island of Bangka. Mine will be more buoyant in operation when a ship or suction dredges on a coast.

Until now, PT Timah alone operates 11 dredgers. While the partners of PT Timah operate 55 ships suction. Not known how many ships suction dredgers and other parties operated in the waters of Bangka Belitung. The reason, no definite data.
