Several members of Congress representing coastal states are voicing concern about a proposed federal regulation that could pre-empt state bans on buying or selling shark fins.
Rep. Jared Huffman, D-San Rafael, is being joined by representatives of New York, Florida and Guam in seeking changes to a proposal they say would take away a state tool to protect shark populations.
California, Hawaii, New York and several other states have passed regulations on the sale and trade of shark fins, which are used in a soup considered an Asian delicacy. California's ban on the sale, trade and possession of shark fins will go into effect Monday after a compromise allowed time for restaurants and businesses to use up supplies.
A letter from the representatives and the delegate from Guam states that a proposed rule by the National Oceanic and Atmospheric Administration's fisheries management division, the National Marine Fisheries Services, would undermine those laws.
California state lawmakers were also circulating an opposition letter.
"If we are to address the problem of shark-finning head on, we must allow state and territorial statutes to complement the federal regulations and further the U.S. leadership in global shark conservation," states the letter, which has not yet been sent to the fisheries service but was given in advance to the AP.
In addition to Huffman, it is to be signed by Democratic Reps. Sam Farr of California and Grace Meng of New York, Florida Republican Rep. Vern Buchanan and Democratic Delegate Madeleine Bordallo of Guam.
The proposal under consideration says state and territory shark fin laws are pre-empted if they are found to be inconsistent with federal fishery management plans or regulations.
Conservation and animal welfare groups have begun circulating petitions against the proposal, but representatives of the fishing industry have argued that federal pre-emption is necessary to maintain fishing of commercially viable shark species.
Congress passed and President Barack Obama signed the Shark Conservation Act of 2010 in an effort to strengthen federal laws against shark finning in U.S. waters and require that sharks be landed with their fins still attached. Since then, the fisheries service has been working to craft regulations to implement the act.
Conservation and animal advocacy groups said fishermen have been able to sidestep the rules by taking only the fins of sharks and dumping the carcasses back into the sea. Advocates say tens of millions of sharks are killed each year for the worldwide demand of shark fins and products.
Jill Hepp, director of shark conservation at The Pew Charitable Trusts, said states should have the right to go beyond federal rules in protecting shark populations.
"If this goes forward as they are proposing, this has the potential to undermine the states' shark fin trade ban and it would be a considerable setback for global shark conservation," Hepp said.
But John Whiteside, an attorney for Sustainable Fisheries Association, a Massachusetts nonprofit founded by four seafood processors, said the federal government should have the final say over regulations, especially fish caught in federal waters.
Not doing so would violate trade laws and run afoul of treaties the federal government has with governments around the world, he said. Commercial fishing groups were successful at getting exemptions in some states for certain species of sharks, such as the dogfish, a small shark also used for fish and chips that is sustainably harvested.
