LCPRCG is a voluntary team of riparian anglers based around the shores of Lough Corrib SAC who monitor the presence of invasive Northern pike (Esox lucius) in the lake and who suppress Northern pike numbers with rod and line angling.

🐟 Northern Pike (Esox lucius) are native to most of Alaska, but do not occur naturally south and east of the Alaska Range. Pike were first illegally introduced in Southcentral area waters and are now spreading through open waterways, decimating salmon and trout populations. This ecological damage can negatively affect the economy by reducing recreational fishing opportunities. ADF&G along with partners in the Alaska Invasive Species Partnership (AKISP) have developed management plans and have increased public awareness in efforts to detect, eradicate, contain, and suppress invasive Northern Pike populations.

🔎 Learn about Northern Pike and more about invasive species management at the upcoming Invasive Species Workshop happening in Juneau on October 27-29, 2026. Registration is open for in-person and virtual attendees. Register here: https://alaskainvasives.org/?page_id=134

🚨 BREAKING: ALASKA HAS AN INVASIVE WILDLIFE PROBLEM — AND IT’S NOT WHAT YOU’D EXPECT! 🏔️😳

Alaska has strict rules and monitoring programs for invasive species because nonnative animals can harm native wildlife, habitats, and local economies. The Alaska Department of Fish and Game specifically identifies several invasive species as concerns, including northern pike in aquatic ecosystems.

And no, it’s not just bears wandering around somebody’s cabin at 2 AM or a moose blocking the road like it owns the highway. 🐻🫎💀

We’re talking about animals that can spread beyond their natural range and disrupt ecosystems.

🐟 One major example: northern pike

These predatory fish have been introduced into some Alaska waters where they aren't native. They can prey on native fish and create serious problems for local fisheries.

Meanwhile, Alaska officials continue to emphasize reporting unusual invasive species sightings and preventing their spread.

So somewhere in Alaska right now:

• A fisherman may pull up a fish that shouldn't be there
• A remote lake could be dealing with an unwanted predator
• And somebody is probably saying, “Wait… how did THAT get here?” 😳

Alaska may be famous for bears, moose, wolves, and massive wilderness…

But protecting that wilderness also means keeping invasive species from getting established. 🏔️❄️🐟

Only in Alaska — where even the wildlife story can have a plot twist. 😂🏔️

This fall, many salmon will swim hundreds of miles upstream to spawn where they first hatched, while facing obstacles like low water flows and natural predators. Don’t let the invasive northern pike join that list!

Northern pike are aggressive invasive predatory fish that eat juvenile salmon and other native fish and threaten to undo years of salmon recovery. Due to illegal stocking, this species has been established in the upper Columbia River Watershed above the Grand Coulee Dam, only two dams away from vital spawning habitat.

You can help protect Washington’s salmon by learning how to identify a northern pike, and if you catch one, DO NOT RELEASE IT! Kill it, take a photo, and report it. They are a prohibited species, so it is illegal to transport any live fish.

In a remote corner of Southcentral Alaska, state biologists carried out a dramatic restoration: they treated an entire lake with rotenone, a plant-derived piscicide, to wipe out an invasive population of northern pike. After the treatment, post-surveys confirmed the pike were gone.

More great work removing invasive pike from Lough Corrib SAC.

Thanks to all the anglers who sent in photos.

🚨 Biologists scan Columbia River for invasive northern pike DNA to protect threatened salmon runs

Federal crews are testing water samples between hydropower dams on the Columbia River, searching for genetic traces of northern pike before the aggressive predator can threaten 13 protected salmon and steelhead populations. The illegally introduced fish could devastate juvenile salmon migrating to the Pacific Ocean, potentially undoing decades of conservation work. Recent tests show negative results, but scientists warn that river conditions can dilute DNA evidence, making ongoing surveillance critical to catch any invasion early.
