Randy, we know you’re based in Fairbanks and work the northern parts of Alaska. How do Dolly Varden fit into the fish community there, especially on the North Slope?

In terms of those big Dollies, they occur where the freshwater food choices aren’t so great but the ocean has abundant food. Let’s talk about that.

Shublik Spring emerges from a mountainside in Arctic National Wildlife Refuge before flowing across tundra and into the Canning River. It flows at the same volume and temperature (~5.5ᵒC) all year, every year. Radio carbon dating indicates this ancient water was last exposed to the atmosphere 1,200 years ago. 📷 USFWS/Randy Brown

Arctic National Wildlife Refuge is a pretty special place. People don’t tend to think about the fish maybe as much as the caribou or the crazy diversity of birds that come here from all over the world to breed. If somebody wanted to go fish in Arctic Refuge, is that possible? Can you do a float? What do you need to think about to plan a trip like that?

For someone who hasn’t seen Arctic Refuge and the area north of the Brooks Range, what’s it like?

Where can you find Dollies on the North Slope of Alaska?

Is that coloration where they get their name from?

How do you tell the different char species apart?

They appear to be very similar in form and behavior to salmon and trout — are they a good sport fish?

There used to be a bounty on Dolly Varden in the early days. You’d get a payment if you turned in their tails because people were concerned Dollies were eating young trout and salmon.

So would salmon eggs be a good lure choice?

If someone were to fish for them, they’d want to get something maybe big and flashy — like a spinner — that might work well to entice a strike?

Fascinating stuff. Thank you so much, Randy. To all you fish fans out there: we hope you get out and enjoy All The Fish!
