Chinook were added to the salmon stockings in 1967. The 4-H Name and Emblem have special protections from Congress, protected by code 18 USC 707. This does not mean that alewife completely disappeared from the lake, but it does mean that less food is available for predators in open water. This leaves little over for secondary consumers, or prey species, and hence the predators who depend on them. Today, Atlantic salmon are stocked in the St. Mary's River and in other parts of the upper Great Lakes. Following Lake Michigan Committee (LMC) recommendations that slashed lake-wide Chinook stocking 2017, Indiana went to a goal of 75,000 total Chinook released in alternate year in Trail and the Little Cal. Today, the Great Lakes provide unique fishing opportunities for Chinook, coho, Atlantic and pink salmon, attracting anglers from around the world to Michigan. This means less than ten pounds of prey per pound of predator in Lake Michigan, which is similar to Lake Huron before the collapse. Lake Michigan anglers who have wanted more king salmon to catch are getting their wish. Decomposers are tiny animals that feed on detritus and release nutrients for producers to use. Two down, two to go. The DNR plans a major increase in chinook stocking for Lake Michigan. Wisconsin's Lake Michigan Management Reports to the Great Lakes Fishery Commission, 2017 [PDF] Great Lakes Salmon and Trout Reports. The new targets include lakewide increases in stocking for Chinook Salmon, Brown Trout, Rainbow Trout, and Coho Salmon, and a reduction in Lake Trout stocking at the Mid-Lake Reef in 2021. Fisheries managers issued a new proposal to reduce stocking of Chinook salmon and lake trout. The goals are to preserve some fishing opportunities without allowing the prey species to collapse. • Stocking allocation model created in 1986 • Model has been used since 1986 to allocate salmon/trout stocking numbers by management zone • Since 1990, the split has been 54% North and 46% South • Stocking numbers have matched stocking quotas fairly well • Stocking in 2013 using this model distributes chinook salmon based on 150,00 at Strawberry Creek and 54% North and 46% South Today, Atlantic salmon are stocked in the St. Mary's River and in other parts of the upper Great Lakes. The Zebra and Quagga mussels are super-efficient filter feeders and consume much of the primary production biomass in the lakes. Click on the timeline below to find out more. Part 2 of this series is at http://youtu.be/7ktDYPjJj_0The Great Lakes have changed dramatically over the past two centuries. "The size of the salmon has also improved, with hundreds weighing more than 30 pounds caught at multiple ports." Sculpin and goby are examples of bottom-dwelling fish have been doing better than alewife since the invasion of quagga mussels and related food web changes. However, lake trout stocking in northern Lake Michigan portions of the 1836 Treaty waters is required by the 2000 Consent Decree to reflect an “expanded commitment to lake trout rehabilitation” and avoid lowering the established lake trout harvest limit. All of the statements above are based on the best available scientific information – but scientists will be the first to point out that “best available” does not mean perfect. However, Chinook salmon consumption is still higher than lake trout (33.1 kt). The result is rising populations of native Lake Trout, Cisco and non-native steelhead, even as Chinook populations decline. Design and Illustration: Octane Design | Programming: Steve Fogg. No, most of the Chinook caught by anglers in 2013 were age-3 fish from the 2010 year class. Welland Canal connecting Lake Ontario to Lake Erie allows ship traffic to bypass Niagara Falls and access the upper Great Lakes. Slide down the timeline to see changing mussel and plankton denisity in Lake Michigan. The USGS Great Lakes Science Center’s bottom trawl survey found that yearling and older alewife biomass density dropped to 0.14 kg/ha in 2015, the lowest since monitoring began in 1973. Expenditures of Great Lakes Salmon and Trout Revenues, Fiscal Years 2008-2013 [PDF] Lake Michigan Salmonid Stocking. More than 90 percent of the stocked fish caught in Grand Haven were stocked elsewhere. Primary consumers are tiny organisms such as zooplankton and macroinvertebrates that live in the water column or in the sediments at the bottom of the lake and feed on primary producers. In 2015, the Lake Michigan Committee approved a lake trout stocking reduction of 550,000 fall fingerlings (220,000 yearling equivalents). Lake Michigan Chinook salmon stocking levels will remain the same as in 2013, meaning no further cuts will take place in 2014. It was an easy decision, 30 years ago, for the Michigan DNR to discontinue the coho program in Lake Huron. Increased stocking was considered by managers after natural reproduction in the rivers of other states bordering Lake Michigan. Many anglers, charter captains, and community leaders along the shores of Lake Michigan are wondering how a reduction in Chinook salmon stocking might affect fishing and tourism. The experiment was a success, and the result was a multi-billion dollar sport salmon fishery that lasted into the first decade of the 21st century. ... Trout spawning habitat in Illinois waters of Lake Michigan through a collaborative project with the Illinois Natural History Survey (INHS). The stocking schedule of trout and salmon in Indiana waters of Lake Michigan includes: yearling summer-run Skamania steelhead stocked in early April (14-months of age), Chinook salmon in early May (6-months of age), brown trout in mid-March (4-months of age), fingerling summer-run Skamania steelhead in October (8-months of age), coho salmon in early November (12-months of age), and … Both states are planning to raise and release an additional 150,000 chinooks, or 300,000 combined. Biologists believe that the new stocking regime will result in an average of 1500-2000 coho salmon and 3500-4500 steelhead during the summer/fall period, for a total of 5000-6500 fish. 5. They take 20-some years to reach full size. Alewives and sea lamprey enter Lake Erie from Lake Ontario via the Welland Canal. Michigan Sea Grant helps to foster economic growth and protect Michigan’s coastal, Great Lakes resources through education, research and outreach. I have to wonder if this equation takes into consideration the life expectancy of a Lake Trout versus a Chinook. Fish & Wildlife Service’s Great Lakes Mass Marking Program, wild-spawned Chinook salmon made up 71 percent of the Chinook catch for Michigan anglers in 2014-2015. These fish weighed a combined total of 311 tons. The salmon sport fishery in the Great Lakes is significant, generating millions of dollars in local economies. In June, fisheries agencies issued a proposal to reduce Chinook salmon stocking in Lake Michigan by 62 percent. In the 1950s, the sea lamprey, a parasitic, jawless fish that feeds by attaching itself to its victims, decimated the native Lake Trout population. Anglers and biologists realize that lake trout are increasingly important in terms of their impact on prey fish, but Chinooks are still “kings” when it comes to bait consumption. Lake Michigan is no exception. One Chinook equals 3.2 coho, 2.4 steelhead, 2.3 lake trout or 2.2 brown trout." Did the 2013 stocking cuts cause this? HASLETT, Mich. (AP) — Close to 10 million chinook and coho salmon swim in Lake Michigan, Lake Huron and Lake Superior. This marks the first salmon-stocking increase in Lake Michigan since 1999. This means less to eat for prey species that some top predators like Chinook salmon depend upon. According to Michigan DNR consumption estimates, lake trout consumption of prey fish rose from 14.9 kilotons (kt) in 2011 to 23.1 kt in 2015.

The Departments of Natural Resources in Michigan and Indiana have announced significant increases in chinook-salmon stocking beginning in 2020. In the short term, severe stocking cuts could have a noticeable effect on catches in some areas of the lake. Although the situation may have improved this year judging by angler reports, the Predator-Prey Ratio is based on a variety of data sources that take time to collect and analyze. Now, the salmon population is declining and the lake is transforming again. Today, fishery managers are faced with a decision: should they keep stocking salmon at high levels and risk a collapse of the alewives in Lake Michigan, or should they reduce salmon numbers? Stocking in public waters of Michigan must ultimately be approved and permitted by Michigan Department of Natural Resources. In 1970, for example, 576, 000 coho salmon (12% of those planted in 1969) were caught by anglers in Lake Michigan. Lake Michigan Salmon and Trout Stocking.

This reduction is being implemented in fall of 2016 independent of any Chinook salmon cut or additional measures related to lake trout. These pathways allowed exotic species to enter the Great Lakes. Over in Michigan, a bright fishery biologist named Dr. Howard Tanner was serving as head of the state’s DNR Division of Fisheries and began looking for ways to turn the alewife infestation into an opportunity. Native fisheries decline: Ciscoes (lake herring and chubs), lake trout, and whitefish populations plummet. Will further Chinook salmon stocking cuts take place in 2014?
