Muskegon River walleye egg collection to occur this spring


 

The Department of Natural Resources (DNR) reminds Muskegon River anglers that Fisheries Division personnel will be taking walleye eggs below Croton Dam this spring.

The DNR plans to collect approximately 62 million walleye eggs from the Muskegon River in 2014 that will result in 13.4 million fry for transfer to rearing ponds throughout the Lower Peninsula. These walleye will be raised to fingerling size and stocked in late spring or early summer in lakes and rivers throughout the state.

Lake Michigan walleye populations in the Lower Peninsula depend on the fingerlings produced from Muskegon River eggs, as well as many inland lakes in the Lower Peninsula. The size of the walleye spawning run in the Muskegon River is presently about 40,000 to 50,000 each year. DNR crews will strip milt and eggs from approximately 700 adult fish, which will be returned to the river, except for 60 that will be sent to Michigan State University for fish health testing.

“This adult population consists of mostly stocked fish,” said Rich O’Neal, fisheries biologist for the Central Lake Michigan Management Unit. “The Muskegon River has the largest run of walleye in the Lake Michigan watershed south of Green Bay.”

The DNR plans to collect walleyes with an electro-fishing boat beginning as early as the week of March 24 and concluding by April 15. Eight days of fish collections are planned during this period. The actual date when collections will begin depends on water temperatures and the presence of ripe fish. This schedule can change on a daily basis for many reasons, but it is anticipated most work will be completed during the last week of March through the second week of April.

Sampling using electro-fishing usually begins each day at Croton Dam at about 8:30 a.m. and proceeds downstream to the Pine Street access site. If more eggs are needed, additional collections may occur downstream to the Thornapple Street access site.

Egg collection and fertilizing is conducted at the Pine Street access site, about 2 miles downstream of Croton Dam. This process generally begins between 10:30 and 11:30 a.m. The public is welcome to observe how the eggs are removed from the fish and fertilized before they are packed and shipped to Wolf Lake and Platte River state fish hatcheries.

Anglers who wish to avoid the walleye collection activities should fish downstream of the areas of the river previously noted. The DNR asks anglers to exhibit caution when fishing near the electro-fishing boats. Wading anglers will be asked to exit the water when the boat approaches to ensure anglers’ safety during the electro-fishing work. The DNR appreciates angler cooperation during this critical egg take operation.

DNRE returning walleye fry production to historic levels


The Department of Natural Resources and Environment has begun gearing up to return hatchery production of walleyes to historic levels.
The DNRE plans to take some 50 million eggs this spring to produce fry for pond-rearing and direct stocking, an eight-fold increase over the last two years.
Since 2006, the DNRE has cut back on most of its walleye rearing activities because of the presence of Viral Hemorrhagic Septicemia (VHS) in the brood-stock waters. Now, after several years of testing, a technique has been found to disinfect walleye eggs and prevent spreading VHS. As a result, the DNRE will now resume large-scale rearing and stocking of walleyes.
“In a perfect world, we wouldn’t have cut our walleye fry production,” DNRE Director Rebecca Humphries said. “But the specter of bringing VHS into our hatchery system or transferring VHS to new waters was just too risky. The ecosystem is constantly changing and our management practices must change with it. We are pleased that an effective treatment for walleye eggs against VHS has been found and we’re ramping up our production accordingly.”
The DNRE expects it to take two years to return to full production of walleye fry. A number of the rearing ponds, which have been idled for the last several years, are in need of maintenance before they can be brought back on line for production.
Nonetheless, the DNRE expects to produce at least 80 percent of the total capacity for walleye fry in 2011 and be back to full production in 2012. For more information, visit http://www.michigan.gov/dnrfishingwww.michigan.gov/dnrfishing.
