Avid catch-and-release angler almost didn't keep the 5-pound, 12-ounce fish

BEND, Ore. (KTVZ) — Alex Dietz of Bend was fly-fishing with an egg pattern on the Deschutes River outside Warm Springs on Dec. 19 when he hooked a 5-pound, 12-ounce, 24-inch long mountain whitefish with a 14-inch girth.

"My fishing buddy, Jason Schreiber, saw that I had a big fish on and came over to check out what was going on," Dietz explained recently. "We took pictures of it and kind of laughed about it for awhile.

I was getting ready to let the fish go when we realized this thing could be a state record."

Dietz is almost exclusively a catch-and-release angler — but he kept this fish, bringing it to Newport Avenue Market in Bend for an official weigh-in on an Oregon Dept of Agriculture scale, as required under the record rules.

The Oregon Department of Fish and Wildlife certified the fish as the new state record mountain whitefish on Jan. 7, beating the previous record, a 4-pound, 14-ounce mountain whitefish caught at Crane Prairie Reservoir in 1994 by Roger A Massey.

Dietz's mountain whitefish might actually be a world record, as the current record is a 5-pound, 8-ounce whitefish taken by Albert Woo in 1995 from Albert's River near Calgary, according to the International Game Fish Association. Dietz is submitting the information to the IFGA to be certified.

Dietz grew up in Bend and has been fishing since he was in high school. He usually targets trout and steelhead and again, releases just about everything he catches. This record fish is being taxidermized for display at his home.

Beating the record is extra-special, because Dec. 19 was the first time he'd been fishing since he and his wife Andrea welcomed their first child, a baby girl, on Nov. 15.

"December 19 was the first time I got the green light from my wife to go fishing, so big thanks to her, too," Dietz said.

Mountain whitefish are a native migratory fish in Oregon and are distributed throughout most the Western United States and Canada. These fish are typically found in cool mountain streams, but also occur in lakes.

Mountain whitefish have a subterminal mouth, which helps them feed on a variety of food items that occur on the bottom of streams, such as immature mayflies, stoneflies, and caddisflies, which the Deschutes River has in abundance.

"We have known for a long time that the lower Deschutes River has an abundance of mountain whitefish which anglers frequently catch while angling for trout," said Jason Seals, ODFW Deschutes District fish biologist. "However, we never suspected that the Deschutes could have the state and possible world record mountain whitefish so this was a great surprise."

    1. It’s OK,there are an abundance of beautiful whitefish in the river. Sorry that you feel the fish had a sad fate. When I catch whitefish I just chuck them in the bushes for the other critters to feast on. We all have different feeling about different things and thats OK. 🙂

    1. Maybe not fishing but I’m sure there are many things in your life your husband needs permission for. Don’t try and make yourself look better than others, nobody cares.

    2. He’s a brand new father to a newborn. You bet your ass he consulted with the mother before being gone all day for recreation. She probably felt that he deserved it and needed a break. I promise you, there was a trade off in that discussion😆

  1. Nice fish Dude! Those things are nothing more than a nuisance on the Deschutes. And surprise, surprise, the state biologist had no idea that big of whitefish were around here. Those experts don’t know have of what they think they do. It is the height of arrogance to think you can know everything about any part of nature. Including global warming, errrr, climate change, RNA/DNA, gain of function, etc, etc, etc.
