In recent years, concern has been growing about bycatch of juvenile bigeye tuna by purse-seiners setting nets on drifting fish aggregation devices (dFADs). The main target of the purse-seiners is the more plentiful skipjack tuna, but as bigeye inhabit the same tropical seas, they are often taken as well.
The devices typically consist of a raft or buoy trailing a length of disused netting tied into the shape of a string of sausages, used to… Read More

Japan’s catch of glass eels continues to decline, mostly due to the side-effects of dams and other river modifications, but closed-cycle breeding is advancing in the… Read More
