Cisco are taken by commercial fisheries in Lake Superior and Lake Huron’s North Channel, and popular recreational fisheries exist on the St. The cisco is one of the few species that is sought by recreational anglers and commercial fishers, in addition to being an important forage fish. Stocking predators or competitors is also recognized as the cause of cisco decline in some inland lakes. Inland lakes that do retain high water quality are often stocked with trout, which also require cold oxygenated water, or other gamefish. Increased nutrient levels accelerate plant and algae growth, which in turn drives greater decomposition below the thermocline of stratified lakes, depleting oxygen required for cisco to thrive. Management issuesĬisco are sometimes called the “canaries of cold water.” They do not tolerate warm water or low oxygen levels and have declined in, or disappeared from, over 20 percent of their native lakes in Michigan.ĭevelopment and other land use changes can lead to increases in the nutrient phosphorus. Being a coldwater fish, the cisco feeds heavily under the ice. The cisco primarily feeds on microscopic zooplankton, but aquatic insect larvae, adult mayflies and stoneflies, and other bottom-dwelling invertebrates are also eaten by adults. Spawning generally occurs in the shallows of lakes over a clean bottom, although cisco also spawn in open waters of Lake Superior and in some streams. They spawn as fall gives way to winter and water temperature drops to 40☏. In Lake Superior, cisco mature at 9-12 inches and 2-4 years of age. The common name “lake herring” is misleading, because it is not a member of the herring family (Clupeidae), which includes alewife and gizzard shad. The cisco belongs to the same family as salmon and trout (Salmonidae).
