The Inter-American Tropical Tuna Commission (IATTC), the international body charged with the conservation and management of tuna and associated species in the eastern tropical Pacific Ocean, will meet in San Diego from Nov. 2-7 to consider conservation measures for vulnerable tuna populations.

Fishermen hold empirical knowledge that tuna aggregate under floating objects, such as lengths of old rope, pieces of wood, or even large marine mammals. There is still no full explanation for this aggregation behaviour, but the past 20 years have seen purse-seine fishery operators take advantage of the associated concentrations of fish.

Continued mismanagement could force some tuna populations to quickly go the way of cod, a highly threatened fishery that once helped shape economies of whole nations, leading scientists said in the symposium “Last Best Chance for Tuna: Learning from the Cod Collapse” at the American Association for the Advancement of Science (AAAS) Annual Meeting in Boston on February 18.

Balancing short- and long-term fisheries benefits could have prevented the collapse of the cod populations in Atlantic Canada, and is the last best chance for tuna, says University of British Columbia fisheries economist Rashid Sumaila.
