PACIFIC GROVE, Calif., Dec. 9 (UPI) -- Fishing on one side of the Atlantic affects the other side, researchers say, and bluefin tuna populations on both sides have declined precipitously since 1950.
Two Atlantic bluefin populations were studied -- a western population that spawns in the Gulf of Mexico and is primarily fished by North Americans, and an eastern population spawning in the Mediterranean Sea that is fished by European and North African fishers -- a release from The Ocean Foundation said Friday.
