Besadny Anadromous Fisheries Facility Report
The following information is the salmon and trout processing information for our facility on the Kewaunee River. We will post new information to this site every Tuesday at 4 p.m. from March through April and October through early November. Depending on water conditions and the number of fish in the weir, fish are usually processed on Wednesdays.
In addition, you can read the latest fishing report on our Lake Michigan Outdoor Report page.
Besadny Anadromous Fisheries Facility
BAFF seeforellen gamete collection – Seeforellen brown trout are the only wild strain of brown trout that are stocked into Wisconsin's Great Lakes. Beginning in late October, the Wisconsin Department of Natural Resources (DNR) crews use electroshocking boats on several rivers on Lake Michigan to collect seeforellen adults that are identified by a unique fin clip.
Adult seeforellen are transferred to Besadny Anadromous Fish Facility where they are held in ponds. Once a week from, mid-November to mid-December, staff collect eggs and milt from ripe adults. Fertilized eggs are transferred to the Wild Rose Hatchery. Fish that are not yet ready to spawn are returned to the ponds to be spawned at a later date until the goal of one million eggs is collected. Each year, approximately 400,000 seeforellen are stocked into Wisconsin waters of Lake Michigan (300,000) and Lake Superior (100,000).
History of the seeforellen strain in Wisconsin: The first seeforellen brown trout were stocked in Wisconsin in 1991. The DNR obtained eggs from New York from late 1989 to early 1990. The goal was to promote an extended trophy fishery, as seeforellen tend to live a year or two longer and spawn a month or two later in the fall compared to domestic strains of brown trout. The current Wisconsin state record brown trout for outlying waters is a 41 lb. 8-ounce seeforellen that was caught in southern Lake Michigan near Racine in 2010 by Roger Hellen.
Muskellunge - Since 2010, the DNR has worked cooperatively with Kewaunee County to raise Great Lakes spotted musky at Dana Farm. Each May, nets are set in the Fox River to capture spawning musky. The captured musky are measured, weighed, checked for a fin clip and a PIT Tag, spawned and released back into the Fox River. Fertilized eggs are disinfected, water hardened and transported to Dana Farm.
In a small building next to the hill pond, eggs are placed in hatching jars and allowed to hatch. Following hatching, musky are held in the building until they have consumed their yolk sac and then are stocked into the outdoor ponds. While in these ponds, musky are fed bait fish by the truckload causing rapid growth. By the end of September, they average nearly 12 inches in length. At this time, the musky are seined from the ponds, fin-clipped to denote they were stocked as fingerling, loaded into trucks and hauled to stocking locations around the Bay.
The hill pond has been in use since 2010, while a newly renovated road pond produced its first musky in 2015. The renovation of the road pond was achieved through the generous donations of many musky clubs and the cooperation of the DNR and Kewaunee County. These ponds will continue to raise musky for stocking into Green Bay until either a peer-reviewed disinfection protocol is developed allowing fish to be safely moved from the Fox River to Wild Rose Hatchery or the inland brood lakes produce disease-free eggs in sufficient numbers needed to support the program.
Nov. 3, 2021 Besadny Anadromous Fisheries Facility Report
Six salmon processing days occurred so far this fall at the Besadny Anadromous Fisheries Facility in Kewaunee on October 2, 5, 13, 20, 27 and November 3. Numbers of Chinook salmon processed for data and removed from ponds each day respectively were 34, 209, 160, 103, 29 and 15 (total 550). Numbers of Coho salmon processed for data and removed from ponds each day respectively were 5, 52, 127, 51, 224 and 151 (total 610). Overall, 165 female Coho were spawned and over 303 thousand eggs collected on October 27 and November 3. Additional Coho (about 68) have been sorted and are currently in holding ponds for spawning and data collection during future days. The next processing day and third Coho egg collection at BAFF will be Wednesday November 10.
