Best Practice for Handling Rainy Fish

Rainy Lake is home to a thriving population of trophy-class walleyes, pike, smallmouth bass, and more. Many anglers voluntarily release large fish, especially those within the protected slot limit (currently, walleyes between 18 and 26 inches must be released, with only one over 26 inches allowed in possession). The combined walleye/sauger possession limit is eight, with no more than four walleyes.

Meanwhile, the Rainy River—especially in spring and fall—is famous for its catch-and-release sturgeon season and impressive walleye runs. There is also a brief harvest season for lake sturgeon in early fall, where anglers may keep one fish per year with a purchased sturgeon tag, as defined by the Minnesota DNR Fishing Regulations.

Whether it’s a spring sturgeon trip on the Rainy River or a summer trolling session on Rainy Lake, knowing how to safely release fish ensures the future of our world-class fishery.

Tips to Maximize Fish Survival

1. Consider Water Depth & Temperature:
Fish caught in deep or warm water struggle more with survival post-release. If you’re on Rainy Lake pulling walleyes from 35 feet in August, try moving to shallower water or fishing earlier in the day when temperatures are cooler.
2. Choose Tackle That Minimizes Harm:
Using jigs or lures that promote mouth-hooking reduces internal injury. If a fish swallows the hook deeply, it’s better to cut the line than try to retrieve it—especially true when fishing sturgeon on the Rainy River.
3. Be Ready:
Have your pliers, measuring tape, net, jaw spreader, and camera handy before you start fishing. A quick release helps reduce stress on the fish.

Handling Fish the Right Way

Walleyes:
Grip walleyes by sliding your fingers under the hard cartilage in the gill plate—but never touch the red gills themselves. For larger fish, support their body horizontally by placing your other hand under the belly.
Bass & Crappies:
These can be safely lip-gripped and are relatively easy to handle. Be gentle and avoid squeezing their sides.
Pike & Muskies:
Use a firm grip on the gill plate cartilage and support their body horizontally, especially for larger specimens. Never hold by the eyes—a practice that can cause blindness.

Special Consideration: Releasing Sturgeon

Sturgeon are some of the most incredible—and fragile—fish in our area. These prehistoric giants can reach over 70 inches and weigh several hundred pounds. Because of their size and unique physiology, special care is needed:

• Never hold sturgeon vertically doing so can cause internal damage due to the weight of their own organs.
• Avoid grabbing them by the gills, especially on larger fish.
• The best method: one hand on the tail (firm grip) and the other under the belly to support the body. If the sturgeon is especially large, two anglers should cradle the fish together.
• When possible, release sturgeon in the water. Use a large net if needed and gently remove the hook without lifting the fish into the boat.

Note: Anglers must follow specific seasons and tag requirements when targeting sturgeon. Spring and fall are catch-and-release only, while the early fall harvest season allows for one sturgeon per year with a valid tag. Always check the current DNR regulations before fishing.

Extra Release Tips for All Species

• Don't remove too much slime. This protective coating helps shield fish from parasites and infection.
• Don’t drop fish or place them on dry/hot surfaces.
• Avoid touching the eyes.
• Revive the fish properly: Gently move them side-to-side in the water (never forward and back) to push oxygen into their gills. Hold them upright until they swim away on their own.

Fishing Rainy Lake and the Rainy River is an experience like no other—from chasing trophy walleyes to battling a prehistoric sturgeon. But with that thrill comes responsibility. Practicing smart, ethical catch and release ensures this incredible fishery continues to thrive.
