Unconfirmed information suggests that the Yangzi Hua 44, IUU listed by CCAMLR, has changed name to Wutaishan Anhui 44.
The Wutaishan Anhui 44 was last seen at 0528 GMT on Tuesday 24 April 2012 at position 07°50’south, 102°59’east, heading 052° at 11 knots.
That indicates that the vessel was on her way to Singapore or some other port in the area. The vessel seems to be flagged to Tanzania with Zanzibar as home port.
The new call sign is 5IM488. The call sign and home port can be seen in the pictures below.
The vessel is, as is common for IUU vessels, attempting to hide name and home port under a fishing net.
