Late Spring Influences Fish Reproduction

Monday, October 14, 2013

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.”
