Cormorant Management Coming?

USFWS is looking at ways to reduce impacts of cormorants on recreational fishing and farm ponds.

GON Staff | January 24, 2020

The damaging impact of fish-eating cormorants on recreational fishing is now being looked at by the U.S. Fish and Wildlife Service, and possible measures to control cormorant populations could be allowed in the future. The USFWS is asking for public comment now through March 15, 2020.

An extensive 2017 study on the impacts of cormorants on commercial fish farmers resulted in allowing individual depredation permits in 37 eastern and central states.

“This review did not include potential damage to recreational and commercial fishing by cormorants. Since the publication of the EA, the USFWS engaged stakeholders to assess the biological, social and economic significance of wild fish—cormorant interactions, and to identify a suite of management alternatives,” said a USFWS release. “The Department of the Interior’s U.S. Fish and Wildlife Service is announcing an advance notice of proposed rulemaking (ANPR) and soliciting public input on future management options for cormorants.”

Cormorants often flock to a farm pond, and in a few days can have a major impact on the fish population before moving on to the next lake. They also impact major reservoirs.

Lake Weiss guide Mark Collins has seen the impacts of cormorants on the Coosa River impoundment first-hand.

“These birds feed exclusively on fish, mainly baitfish, but they are opportunity feeders and will eat whatever they can catch. As the cormorant population increases, they will be a direct threat to our game fish and baitfish populations,” Mark said. “They have also been connected to parasites in game fish. They also put a lot of E. coli in the water system. This comes from all the poop in the water.

“They are also causing erosion problems, anywhere they roost. Their poop is so toxic it kills all the vegetation that could stop erosion. We have lost one island here on Weiss from this, and there are two more that will be gone in the near future. They like to roost on islands.”

Cormorants congregate in the Lake Oconee area in big numbers. Guide Doug Nelms said the flocks are so big at times that it’s dangerous to run a boat at half speed because they don’t get out to the way.

“They are in all the places where you find lots of fish, and they eat all sizes. I watched one bird for 15 minutes attempt to eat a white bass that looked like it was about a pound. It was clearly too big for him to swallow, but he kept trying until he succeeded, so they are not just eating shad,” Doug said.
Biologists confirm that a single cormorant eats 1 pound of fish per day.
“I can see how they could easily decimate a fish population,” Doug said. “I see them congregate up the Apalachee when the crappie are there and stay there until long after the spawn, and it makes me think they are eating the small crappie. There is never a time when we don’t see them all over the lake, so I am not sure that any of them migrate out of here, and it seems like they are always feeding. At the timber patch just south of I-20, where many of them roost I guess, the trees are white with their droppings. In this area we are catching a lot of crappie, so they are definitely focusing on areas that hold a lot of fish. I would certainly be in favor of a season or even a predation hunt to keep these things in check,” Doug said.

U.S. Secretary of the Interior David Bernhardt said, “Balancing the protection of native wildlife with economic and human health needs is fundamental to effective management practices. Today’s action starts the process of improving management and further reduces conflicts with double-crested cormorants throughout the United States.”

“We are building long-term solutions for managing conflicts with double-crested cormorants under the Migratory Bird Treaty Act while maintaining healthy populations of this species,” said Aurelia Skipwith, Director of the U.S. Fish and Wildlife Service. “This effort, in collaboration with our partners, will ensure continued good stewardship of our natural resources.”

Former USFWS Director Dale Hall said, “The strong return of double crested cormorants is a significant conservation success. But in the absence of natural predators, cormorants are inflicting substantial depredation on both private and public aquatic resources. This effort by the Fish and Wildlife Service is necessary and appropriate to maintain a healthy ecosystem.”

U.S. Sen. John Boozman, of Arkansas, said, “With nearly 30,000 water surface acres across Arkansas used for aquaculture production, our fish farmers contributed $71.1 million to our state’s economy in 2017. However, the United States Department of Agriculture estimates double-crested cormorants cause more than $25 million in damage annually within the aquaculture industry. These birds have become the foremost antagonists of fish farmers. We need commonsense solutions that allow aquaculture producers to safeguard their fish from these predators. I applaud the U.S. Fish and Wildlife Service for responding to the need of aquaculture producers by increasing the amount of maximum allowable take of double-crested cormorants, and I look forward to working with the Department of Interior and USFWS to ensure we can find commonsense solutions to ease the burden for hard working Arkansan aquaculture producers.”

U.S. Rep. Bruce Westerman, of Arkansas, said, “Science has consistently proven that managing cormorants is necessary to protect not just aquaculture but fishing as well. I applaud the administration for listening to input, increasing the take and promoting sound scientific practices.”

Public comment for the rule-making process began Jan. 22, 2020 and will continue for 45 days until March 9, 2020. The USFWS will take into consideration all comments and any additional information received on or before that date.

Comments opposed to cormorant management are already being submitted by animal-rights activists, including this one: “THIS IS JUST DEMOGOGUREY (sic), MALICIOUS, INSANE KILLING OF BIRDS BY A FEDERAL AGENCY USING YOUR GENERAL TAX DOLLARS TO DO THE MOST MALICIOUS, EVIL KILLING SYSTEM IN THE WORLD TO DO THE DIRTY WORK OF THE FISHERMEN. WILDLIFE IS FAST VANISHING FROM THIS EARTH BECAUSE OF NASTY DISGUSTING PROPOSALS LIKE THIS. THIS PROPOSAL SUCKS. IT SHOWS THE WORST OF AMERICA. SHUT IT DOWN TIGHT AND SAY NO MORE KILILNG (sic) OF WILDLIE (sic) OR CORMORANTS.”
