Farmers in California want killer whales that ply the waters between British Columbia and the U.S. to be removed from the endangered-species list, saying regulations to protect salmon the mammals eat are creating a huge economic burden.
The agricultural industry is being represented by the Pacific Legal Foundation, which has persuaded the National Oceanic and Atmospheric Administration to review whether southern resident killer whales should be delisted.
NOAA said a petition filed on behalf of two farms and the Center for Environmental Science Accuracy and Reliability presents new information from scientific journals that claim the whales are genetically linked to a much larger population and therefore, are not in danger of extinction.
Damien Schiff, a lawyer for the legal foundation, said southern resident killer whales are no different from orcas around the world but U.S. government regulators invented a new sub-category of orca in the Pacific Northwest in order to label them endangered.
Scientists believe there are about 86 southern resident killer whales, which were listed as endangered by the U.S. in 2005 when there were 89 of them, according to NOAA.
"The federal government should continue to look at the killer whale as a single worldwide species," Schiff said.
He said listing the whales as endangered under the federal Endangered Species Act meant cutbacks in irrigation to protect fish but farmers are finding it difficult to expand operations because of the lack of water.
"The most significant reduction was in 2009 and those water deliveries were reduced in part because of the endangered-species protection for this particular population of orca whales," he said.
"At this point, (the farmers) are concerned about their financial future, which is dependent principally on water they've already contracted for."
