...de evidence for their trans-oceanic migrations. A fisherman from the Scandinavian Tuna Club might have chased the same giant bluefin as a Cuban fisherman, says Dr. ODor, a Dalhousie University professor and senior scientist of the Census of Marine Life. Part of the lesson here is that restoring bluefin tuna...Salmon tracking program expands to California

...000 loggerhead turtles were incidentally caught by fisherman scouring the waters for other species such as tuna and swordfish. Of these, tens of thousands are thought to die as a result. 37% of this fishing effort was in the Atlantic and a major hotspot for fishing is found off West Africa, the region where th...Scientist warns of threat to last stronghold of endangered turtle
