late spring fisheries impact

Fisheries biologists who questioned how a late spring and delayed ice-off would influence fish reproduction in North Dakota waters finally have a few answers.


“It looks better than we expected,” said Scott Gangl, State Game and Fish Department fisheries management section leader. “Our biologists have been seeing some pretty good numbers of young-of-the-year yellow perch in lakes statewide, signaling some good reproduction this year. This was especially true in our larger lakes that traditionally provided a perch fishery.”


Devils Lake and Stump Lake reported excellent numbers of young-of-the-year yellow perch. Reports also indicated good numbers of young walleye in the upper reaches of Lake Sakakawea, and fair to good numbers of perch on the east end of the lake.


Reproduction was poor for most fish in the Missouri River and Lake Oahe, which are still recovering from the forage losses during high water in 2011.


“We found some shad and decent numbers of white bass in Oahe,” Gangl said. “This was our second year in a row of stocking shad in Oahe, so it’s nice to see some reproduction of those alternate forages. The sport fishery will have a difficult time recovering without that forage base.”


On another note, Gangl said fisheries biologists are seeing good survival of walleye stocked around the state in North Dakota’s smaller waters.


“There were also fair numbers of young-of-the-year pike,” he said. “While we initially didn’t know what to think of the late spring, it apparently was good for fish.”

it’s an official new state record saugeye

Lab results confirm Dan Faiman’s state record fish is a saugeye.

The Fairview, Mont. angler caught the 12 pound record fish on Jan. 16from the Yellowstone River. Because the fish had identifying characteristics of both species, genetic material was sent to a lab to determine whether the fish was a walleye, sauger or saugeye, which is a cross between the two.

Faiman’s catch broke the previous record, set in 1984, by 4 ounces.

Biologists Hope Shad Boost Oahe Forage Base

Game and Fish Department biologists stocked roughly 225 adult gizzard shad in Lake Oahe’s Beaver Bay in May to help jumpstart a limited forage base.

A good share of Oahe’s young-of-the-year rainbow smelt were flushed through the dam during flooding in 2011, drastically thinning what game fish have to eat. In addition, high flows and sediment-laden water reduced production of other forage fish.

“When we did our fall reproduction survey in 2011, we saw very few young-of-the-year fish in all of the forage species,” said Scott Gangl, North Dakota Game and Fish Department fisheries management section leader. “We knew going into 2012 that there was going to be a forage problem, at least for the short-term.”

Stocking prespawn adult shad was a collaborative effort with South Dakota Game, Fish and Parks fisheries biologists who stocked additional sites on Lake Oahe. “The plan is to give Oahe a little shot in the arm to help boost the forage base,” Gangl said.

If the adults spawn successfully, young-of-the-year shad will be on the game-fish menu by late June or early July.

Gangl said biologists on both sides of the border are trying to mimic the shad boom seen in the mid-2000s when smelt numbers were down. “We watched the shad slowly build over time and they eventually provided a good forage base for game fish,” he said. “We don’t have anything to lose by trying this. It’s certainly worth a shot.”

Gangl said Lake Oahe has a lot of hungry game fish, but the forage shortage is more pronounced on the North Dakota end of the reservoir. “The fish aren’t starving to death, but they are hungry,” he said.

Salmon Anglers Asked to Look for Tag

Anglers who catch a tagged salmon are asked to turn in the heads and report information to the North Dakota Game and Fish Department.


Dave Fryda, Missouri River System supervisor, said while most Lake Sakakawea salmon anglers are aware of the tagging program, anglers fishing the Missouri River – especially the Garrison Dam Tailrace – tend to be less aware of the importance of watching for tagged fish.


“There is no external tag to look for, only the adipose clip,” Fryda said.


The adipose fin is a small fleshy lobe found on the back toward the tail. If the fin is missing, it was likely removed by Game and Fish biologists and the salmon probably has a micro-tag embedded in its head.


Micro-tags are inserted into a sample of young salmon before being stocked into Lake Sakakawea and the Missouri River. This microscopic tag is implanted near the snout, and contains a code that identifies stocking information.


Heads can be turned into Game and Fish, or local bait shops. Anglers will be provided information about the fish when tags are extracted and read by biologists.

Anglers a times have an unrealistic expectation of stocking. In some small lakes, yes stocking is THE reason you have fish. But in Sak, Oahe, Devils Lake, stocking is more of the cottage cheese and carrots of the buffet than the roast beef and ham. It’s a supplement, not the main course. Stocking helps, and it looks like our hatchery’s have had a good year. But please realize that stocking=to fishing takes years for fish to grow from fingerlings to the frying pan.

North Dakota Game and Fish Department fisheries crews stocked a record number of walleye into state waters, according to Jerry Weigel, fisheries production and development section leader.
The Garrison Dam (10 million) and Valley City (1.5 million) national fish hatcheries produced 11.5 million fingerlings, besting the record of 10.9 million in 1991. “Fish quality and stocking conditions were great, with really nice fish and lots of cool water and flooded vegetation at the stocking sites,” Weigel said. “The federal hatchery system really delivered given the record walleye request this year.”
The record total was driven by a higher than normal request of 10.1 million fingerlings, with 4 million targeted for Lake Sakakawea.
“We had another 440,000 requested if surplus production occurred, and all of those requests were filled with most getting up to an additional 10 percent,” Weigel said. “In addition, we also supplied Wyoming and Iowa with walleyes as part of a trade or to cover their production shortages.”
Altogether, 114 lakes and rivers were stocked in North Dakota, Weigel said, covering every corner of the state. “Coupled with natural reproduction, we have set the stage for a phenomenal walleye year,” Weigel continued. “We will know more this fall when our crews follow up to check on survival rate of the stocked fish and determine the amount of natural reproduction.”


indepth on stocking

 The fun thing about a question–from another biologist, angler, reporters and even neighbors is often times I don’t have the full answer. I’m not a fisheries biologist, wildlife biologist or game warden (but I did stay at a Holiday Inn Express…) in fact I relate quickly when asked, that I’m not a practicing biologist. I’m not out in the field researching or documenting. My job is behind a keyboard, in front of a microphone, TV camera and taking the nuts and bolts of what the true biologists and scientists are working on and tabulating, then hammering it out in usable format.Yes I have a degree and have done my share of field work and was a game warden, so I do have a biological foundation to draw from.

So when asked about stocking fish on Jametown Reservoir my short answer of, "it comes down to habitat and isn’t all that different than cattle" needs to be expanded upon a bit. I enjoy the questions and finding the answers, because I learn as well along the way. Like when a kid asks when some asks what Braunschweiger is. It’s easy to come up with the answer but takes much longer to explain what goes into the final product.

Let me go back to stocking and cattle. It takes habitat, in terms of a cow you need grass and water. In terms of fish, you need forage for the fish, water (obvious?) and escape from predators or lack of predators to grow a fish. And like grass and cows, the better the grass, the faster the cows can grow. Just think yourself through the visual and you’ve a better understanding of stocking fish. In the middle of a drought you don’t put more cows on the pasture. Similar in terms of stocking when the habitat and/or forage is gone–the water levels low–or predators are high. Just adding more fish (stocking) won’t help out in the long run.

One last note, unlike deer, pheasants or ducks where the eggs are laid, young born or hatched and within a few months a viable resource is realized for hunters. Fish growth is measured in years and not in weeks or months.

A quick quote specific to Jamestown Reservoir stocking equation(how do you figure out the number stocked) from Gene Van Eeckhout our from our Jamestown Fisheries Divison



We’ve been stocking approximately 100 walleye/surface-acre lately. We stocked 30 pike/surface-acre last year.Survival and growth are highly variable from year to year. Conventional wisdom suggests that during flood years when abundant habitat is inundated, survival is better. Sometimes it takes a year or so before we can document this recruitment.

good news on stocking

North Dakota Game and Fish Department fisheries personnel recently stocked a record number of fingerlings in a record number of state waters.

Jerry Weigel, fisheries production and development section leader, said with additional water scattered throughout the state fisheries staff were geared up for a big year.

“The Garrison Dam and Valley City national fish hatcheries came through with more than 11 million walleye, pike and perch fingerlings, and they were stocked in 180 state waters, 50 more lakes than average,” Weigel said.

Considering none of the three species were stocked into Devils Lake or Lake Sakakawea, the numbers are even more impressive. “In years when we have stocked Lake Sakakawea we exceeded 11 million fingerlings, but Sakakawea alone received several million or more fingerlings,” Weigel said. “At the same time, that is when we typically stock 100-120 individual lakes.”

Weigel said the emphasis on this year’s stocking efforts was to get fish into all the new water areas. “In years like this Mother Nature really cranks up fisheries statewide,” he added. “Our thought process is to ensure all lakes, even those with no brood fish, have a chance of producing a very good year-class of fish that is expected in years such as this.”

In addition, this year’s high water mark has allowed biologists to try to create new perch fisheries. “We do this a little different, because we don’t necessarily just capitalize on hatchery production,” Weigel said. “We visit lakes with an overabundance of smaller fish, remove some of the adults that still have eggs that are ready to spawn, and before they lay their eggs stock them into new waters hoping they will reproduce.”

Weigel said it generally takes lakes with stocked pike fingerlings two years, perch 2-3 years and walleye 3-4 years before they become a viable fishery. “These fingerlings are 1.5-2 inches in length,” he added. “They won’t benefit an angler this year or even next, but year three generally bodes well for the angler.”

Updated stocking reports are available on the Game and Fish Department website at gf.nd.gov. Anglers should access the fishing link.

New South Dakota Fish Record Set
FLANDREAU, S.D. – A Flandreau angler landed a small, strange fish on July 2, and it turned out to be a state record.

Brian Korman was using a worm for bait at the Interstate Pond in Brookings County when he landed a 7.5 inch, 3-ounce European Rudd.

The Rudd is considered an invasive species in the state. It is not wanted in South Dakota waters because the fish can quickly overpopulate and crowd out native species.

Korman submitted the fish to the Department of Game Fish and Parks for state record status. A European Rudd, whose scientific name is Scardinius erythrophthalmus, had never been submitted to GFP before, and Korman’s fish is now in the record books.

I think this is the 4th State Record fish taken in South Dakota this short year

State Record Hybrid Bass Caught

YANKTON, S.D. – Yet another South Dakota angler was in the right place at the right time and landed the fish of a lifetime. Gayville, S.D., fisherman Matt Sarha caught a new state record hybrid bass on May 11.

The fish is a cross between a white bass (Morone chrysops) and striped bass (Morone saxatilis), sometimes referred to as a wiper. The hefty 14-pound, 28-inch hybrid bass was caught on a crankbait in the Missouri River near Yankton.

Hybrid bass are stocked in reservoirs in southern states, with Nebraska being the closest neighboring state with a hybrid bass stocking program. Nebraska’s state record hybrid bass weighed in at 17-pounds, 14-onces.

For a fish to qualify as a state record, the angler must get the fish weighed on a certified scale, have the species verified by a fisheries biologist, or ichthyologist, and fill out a form that can be found at:http://www.sdgfp.info/Wildlife/fishing/StateRecordFishForm.pdf.

Caught or shot…it’s a new record either way. Joshua Bartz’s catch on May 30 is the first entry on North Dakota’s list of state record fish since 2007. The Bismarck angler arrowed a 51-pound, 4-ounce buffalo from the Missouri River near Fox Island in Bismarck.

The 44-inch fish shattered the old record of 40 pounds, 6 ounces taken by Trey Opp of Mandan in 2007 at Heart Butte Reservoir (Lake Tschida).
