OUTDOOR NOTES: NDGF offers walleye tagging update
Year one of a multi-year walleye tagging study on the Missouri River and Lake Oahe is complete, and returns are providing biologists with valuable information, the North Dakota Game and Fish Department said.
According to Scott Gangl, fisheries management section leader for Game and Fish in Bismarck, more than 9,100 fish were tagged in 2013, the first year of the four-year study, and nearly 1,400 tag numbers were turned in by anglers.
The study area extends from the Garrison Dam in central North Dakota downstream to Oahe Dam in South Dakota, and involves a major collaboration of biologists and researchers from North Dakota Game and Fish, South Dakota Game, Fish and Parks, and South Dakota State University.
The study is designed to assess walleye movements, mortality and what proportion of the walleye population is harvested annually by anglers.
Gangl said the first year of the study revealed that fish tagged in North Dakota moved greater distances than those tagged farther downstream. In North Dakota, fish tagged in both Oahe and the Garrison reaches of the Missouri River traveled an average of 40 river miles. Fish tagged in Lake Oahe’s upper and middle zones within South Dakota moved an average of 10 to 15 river miles, and those tagged in the lower zone moved only about five miles. North Dakota fish moved both upstream and downstream after tagging.
Gangl said most of the returns were from May, June and July, and when the fishing slowed in August, so did the returns.
The goal of the four-year study is to tag 10,000 walleyes in the study area in the Dakotas annually, Gangl said, with as many as 4,000 of those fish tagged and released each year in the Missouri River and upper Lake Oahe in North Dakota.

Q. National Volunteer Week is April 6–12. What sort of volunteer opportunities does the Minnesota Department of Natural Resources have to offer?
A. Volunteer opportunities vary across the state from assisting with wildlife research to cleaning rivers to playing Smokey Bear at the State Fair, to name a few. Right now, the DNR is looking for volunteers to help count loons and frogs, plant trees, bait hooks at fishing clinics, build portable field desks and search for rare wildflowers.
Volunteer positions are listed on the DNR website at mndnr.gov/volunteering/opps/index.html or by calling toll free (888) 646-6367.
