Prior to this research, the only known spawning grounds for Atlantic bluefin tuna were in the Gulf of Mexico and the Mediterranean Sea. The evidence for a new western Atlantic spawning ground came from a pair of Northeast Fisheries Science Center (NEFSC) research cruises in the Slope Sea during the summer of 2013.
"We collected 67 larval bluefin tuna during these two cruises...
