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

The last couple of years have been terrible for Japanese squid processors and fishermen.
The national catch of Pacific flying squid fell to around 53,000 metric tons (MT) in 2017, and the 2018 haul hit a low of 41,700 MT. For comparison, 670,000 MT were landed in 2006, and about 200,000 MT were caught in 2011.
This year is shaping up to be slightly better. Landings from January to August in major ports nationwide increased 15 percent… Read More
