Platte River State Fish Hatchery a big part of state’s success with coho salmon

cage of coho salmonSome years back, when Michigan’s Chinook salmon program was in its greatest glory, some anglers suggested the Department of Natural Resources abandon raising the smaller, less spectacular coho salmon and put more emphasis on the kings. The DNR demurred, preferring a multispecies approach.

It appears to have been a wise strategy; Chinook salmon populations are down significantly, largely because of stocking cuts necessitated by a diminishing alewife population in Lake Michigan.

Chinooks depend almost entirely on alewives for their diet. Cohos are more adaptable. As a result, the coho population remains strong. It helped fill out the catch this past summer, as there were fewer Chinooks available to anglers.

Now, the DNR stocks nearly as many coho salmon as Chinooks. A decade ago, it was a quarter as many. Read more

Winterization and Ethanol Blended Fuels

From BoatUS and American Motorcyclist Association

The coming of cooler weather means an end to the boating and motorcycling season for many. Chiefly important in preparing these vehicles for winter is managing the potential for engine damage from the federally-mandated ethanol blend in our nation’s gasoline supply.

Ethanol in gasoline stored for long periods can damage marine and motorcycle engines: “phase separation” of the fuel can leave a corrosive water-soaked ethanol mixture at the bottom of the gas tank. Half of the respondents of a recent Boat Owners Association of The United States (BoatU.S.) survey reported that they have had to replace or repair their boat engine or fuel system parts due to suspected ethanol-related damage, costing an average $1,000 for repairs.

Cod Recovering Rapidly in Canada’s Waters, Slower off U.S.

Cod rebound in warming Canadian waters but continue to decline in U.S.

The rebound of Atlantic cod off Newfoundland and Labrador contrasts with their rapidly declining populations off the northeastern coast of the United States, where until last year the stocks remained significantly below sustainable levels.

The first clue came in 2008, recalled George Rose, a marine biologist at Memorial University of Newfoundland, when he saw the cod aggregating in large numbers offshore during the spawning season. It was a sight he had sorely missed in 15 years. In the early 1990s, cod fisheries suffered such a dramatic collapse that they emerged as an aquatic poster child for fisheries mismanagement, according to Rose.

In a paper published yesterday in the Canadian Journal of Fisheries and Aquatic Sciences, Rose and his colleague, Sherrylynn Rowe, document the comeback of the Atlantic cod off Newfoundland and Labrador over the past decade. The fact that they have shown that the cod stock there is on the way to recovery is good news, Rose said, as “it shows that it is not all gloom and doom.” Read more

Monster Smallmouth Sets New Michigan State Record

Previous state record had stood since 1906

Greg Gasiciel with his state-record smallmouth bass (Oct 2015)The Michigan Department of Natural Resources has confirmed a new state-record catch for smallmouth bass. This marks the sixth state-record fish caught so far in 2015.

The existing state record for smallmouth bass was broken Sunday by Greg Gasiciel of Rhodes, Michigan. Gasiciel was bait-casting with a green grub when he landed a 9.33-pound, 24.50-inch smallmouth bass from Hubbard Lake in Alcona County. Read more

Salmon and trout egg-collection efforts recently finished or just beginning at Michigan DNR facilities

Employee pushing fish through the egg-take process at Little Manistee River WeirThe Department of Natural Resources has been working hard this fall, and will continue to this winter, to gather necessary eggs to maintain the production of hatchery fish to support management objectives for Michigan’s world-class fisheries. Fall egg-takes have been completed or soon will start for wild Chinook and coho salmon and for captive broodstocks of brown, rainbow, brook and lake trout.

Chinook salmon eggs were collected during the week of Oct. 5 at the Little Manistee River weir and earlier this week from the Swan River weir near Rogers City. Coho salmon eggs will be collected at the Platte River State Fish Hatchery weir starting Thursday. Read more

Seasonal lake sturgeon releases put more than 6,300 fish into Michigan waters

The Department of Natural Resources and several partners released more than 6,300 juvenile lake sturgeon into various public waters across Michigan this summer and fall in an effort to rehabilitate this culturally significant fish species.

The table below shows which agencies stocked fish, how many fish were stocked, and the date and location of each stocking effort.

Agency Number of Fish Stocked Date Stocked Location Stocked
DNR 663 July 29-Sept. 5 Otsego Lake (Otsego County)
DNR and Michigan State University 523 Aug. 22-Sept. 25 Black Lake (Cheboygan County)
Little Traverse Bay Band of Odawa Indians 494 Sept. 10 Burt Lake/Cheboygan River (Cheboygan County)
DNR and Michigan State University 500 Aug. 22-Sept. 8 Mullet Lake (Cheboygan County)
DNR and Michigan State University 53 Sept. 8 Sturgeon River (Cheboygan County)
DNR 1,067 Aug. 31-Sept. 14 Cedar River (Menominee County)
DNR and Gun Lake Tribe 12 July 28 Kalamazoo River (Allegan County)
Little River Band of Ottawa Indians 241 Sept. 12 Big Manistee River (Manistee County)

DNR and U.S. Fish and Wildlife Service 820 Aug. 24 Ontonagon River (Ontonagon County)
Total Lake Sturgeon Stocked: 6,310

All juvenile lake sturgeon were collected from the wild last spring and reared in streamside facilities until they reached at least 7 inches or larger in size. All fish are tagged prior to being released into their respective rivers. Read more

New fishing regulations adopted at Thursday’s NRC meeting

The Michigan Natural Resources Commission Thursday approved several fishing regulations at its meeting in Cedarville. Many of these regulations immediately went into effect. They will remain in effect for the 2016 fishing season (which begins April 1).

All of the changes are highlighted below and also are reflected in the online version of the 2015 Michigan Fishing Guide, available at michigan.gov/fishingguide. These regulation changes are part of Fisheries Order 215. Read more

New stream-restoration approach may pay dividends in Michigan

A relatively new technique for stabilizing eroding stream banks is showing great promise in Michigan, as a demonstration project on Highbank Creek in Barry County has not only repaired a damaged creek, but has provided excellent fish habitat as well.

DNR crew works on a river bankThe technique, called “toe wood,” has been around for about a decade but hasn’t been used much in Michigan until now. Department of Natural Resources fisheries biologist Chris Freiburger learned of the technique and thought it had applications for some of the issues facing Michigan streams.

The area Freiburger chose for the demonstration project involved a stream that had been dammed for a mill more than a century ago. The dam had been partially removed in the 1920s, but the abutments were left in place until the landowner knocked them down into the creek out of safety concerns. The debris formed a partial dam that not only impeded fish passage, but also contributed to erosion on the stream. A significant amount of sediment was swept downstream, silting in about an acre and a half of Thornapple Lake.

The Barry Conservation District applied for a U.S. Fish and Wildlife Service fish passage grant, as well as a DNR aquatic habitat grant to remove the dam and restore the stream. Read more

Betsie River spawning closure lifted, effective immediately

The Michigan Natural Resources Commission on Thursday, Sept. 10, lifted a spawning closure on the Betsie River in Benzie County. The lift went into effect immediately.

In 2012, the closure was put in place when the Betsie River experienced historically low water levels that left migrating Chinook salmon and steelhead vulnerable to illegal harvest. Recent weather patterns have resulted in water levels returning to normal conditions, so the spawning closure placed on the Betsie River mouth is no longer necessary. Read more
