U.S. policymakers know they need to limit the number of Atlantic bluefin tuna caught and killed by surface longlines which can stretch 40 miles with more than 750 baited hooks and float unattended for up to 18 hours. After all, the western Atlantic bluefin population is down 64 percent from its level in the 1970s, according to international scientists, due in part to this indiscriminate fishing gear. Yet an effective, comprehensive solution to this problem remains elusive.
On August 21, however, the National Oceanic and Atmospheric Administration, or NOAA, issued a proposed rule that could help protect depleted Atlantic bluefin from surface longlines. These regulations would be a step in the right direction, but we need more changes to effectively safeguard one of the most remarkable, yet depleted, fish in the sea.
Commercial fishermen use surface longlines primarily to target swordfish and yellowfin tuna, but too often they catch bluefin tuna instead. For western Atlantic bluefin, which use the Gulf of Mexico’s waters as their only known spawning grounds, surface longlines are a serious problem. NOAA’s proposed rule contains several changes to improve the management of Atlantic bluefin in the Gulf and Atlantic Ocean, with a focus on limiting the number of bluefin killed by the U.S. surface longline fleet. This includes provisions to:
Several aspects of this proposed rule are promising for bluefin conservation. Under the new annual cap system, for example, once longline users exhausted their quota they would have to stop fishing unless they were able to purchase some of the quota belonging to another vessel operator. That would introduce a level of accountability for fishermen using surface longlines that has never existed–creating a real economic disincentive to catch bluefin with this gear.
Yet there are a number of places where the proposed rule should be stronger. While NOAA is proposing restrictions on the use of surface longline fishing in a portion of the northwestern Gulf of Mexico, that provision is insufficient. To fully protect bluefin, the area should encompass the entire Gulf of Mexico, so that it includes all known important breeding grounds, and the entire peak spawning season, March through May.
Also problematic is a provision that would take away a set amount of the bluefin quota from fishermen using targeted methods and give it to the surface longline fleet. This would be a major step backward in the protection of Atlantic bluefin tuna and the goal of promoting sustainable fishing. As drafted, this quota reallocation would seriously undercut current efforts to promote the use of new, more selective fishing gear technologies to catch swordfish and yellowfin tuna–many of which have been developed cooperatively by scientists and enterprising fishermen in the Gulf.
From my days working at NOAA, I know how hard it is to strike the right balance in a proposed rule. But taking quota from other fishing sectors and giving it to vessel operators using wasteful surface longlines would be neither fair nor balanced. NOAA’s leadership must not let that provision move forward.
