UMaine study shows Penobscot River restoration efforts may benefit both salmon a

“We were surprised to see a strong relationship between increasing river herring returns and decreasing seal-induced injury to salmon. Although this finding is encouraging, we also recognize that the injuries we see only represent failed predation attempts. Future research on seal foraging behavior and diet in the Penobscot River estuary is needed to help explain how injury relates to what seals are successfully eating,” says Leach.
The study shows that restoration focused on ecosystem health can benefit multiple species in ecosystems like the Penobscot River and can shift predator-prey interactions in a way that supports restoration and conservation efforts of both predators and prey.
“Though challenging to implement and assess, multi-species or ecosystem-based approaches to management have great potential for widespread benefits, from fish to seals and even human residents and visitors to the region,” says Kristina Cammen, assistant professor at the School of Marine Sciences and co-author of the study."

a license to kill seals would go a long way to help salmon restoration

Oregon's DFW does (or used to do) this but with Sea Lions to protect their salmon (steelhead) runs.

They are a problem out here on Lake Huron too. Or at least they used to be. One biologist told me several years back that they only got a 1/2 of 1 percent return on their brown trout plantings due to the comorants and walleye. I guess the cormorants home in on the schools of fish and really hammer them. Not sure it's as bad as it was as they did get permission from the feds to blast a bunch of them and destroy there eggs on one island.
