I would like to provide an update on our post from earlier this month on the Fu Yuan Yu Fleet appearing near the search site for Malaysian Airlines Flight 370. We were puzzled to see a large number of fishing vessels at this remote location. Since our post we have received information indicating that these vessels are licensed Chinese fishing vessels targeting small pelagic species.
If as reported the Fu Yuan Yu vessels 070, 071, 072, 073, 075, 076 are targeting small pelagic species (not tuna) then they would not need to be licensed by an RFMO (Regional Fishery Management Organization) in the Indian Ocean. However we are still curious about the fishing methods of this fleet, described as lightning purse seiners. The lightning presumably refers to use of light attraction in their fishing operation.
Each parent vessel appears to be associated with a string of 5 or 6 AIS beacons attached to some type of gear. The vessel and gear can be drifting and strung out in a 30 mile string as seen in the recent screenshots below. Or at other times each parent vessel and set of associated gear is in the same location. This pattern made us think of setting and retrieving a longline but these vessels have now been reported as purse seiners so the fishing operation is puzzling. Below you will see track for one of the fishing vessels, Fu Yuan Yu 070, as well as what we assume is a piece of associated fishing gear (070 04). The two tracks can be seen to overlay closely. We are looking for further information to clarify the fishing operation taking place.
