Census of Marine Life historians detail collapse of bluefin tuna population off northern Europe

as could be better protected thanks to tagging data showing where the species spawns from March to June. Past research showed breeding locations are similar to areas where the bluefin by-catch is high.

Together these new reports help define where bluefin spawn and provide 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 populations to health requires us to consider and manage activities one-fifth of the way around the world.
