The team also will distribute an electronic survey to key stakeholders involved in, or likely affected by, future cisco management decisions. They will present this information at regular meetings held by charter fishing associations, regional fishery regulators, and Lake Michigan ecosystem managers. The research team will use existing data and guided discussions to help stakeholders create a path for cisco restoration in Lake Michigan.ĭrawing from existing publications, reports, and databases, the team will pool information about food web dynamics, rearing methods, fishery regulations, and other relevant topics. Lead Project Investigator: Sara Adlerstein Northern pike and lake trout also prey heavily on cisco where they are available. One study from Ontario found that walleye grew more efficiently, required fewer meals, and expended less energy in inland lakes with cisco as the major forage fish. With soft fins, fatty meat, and ideal size, the cisco makes a perfect prey fish. Fly fishing can be effective during the Hex hatch (annual mayfly emergence). Teardrop jigs and small baits like waxworms or wigglers are effective through the ice and in open water. 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). Other members of the genus Coregonus include lake whitefish, bloater chub, and five species of deepwater ciscoes that are extinct or extirpated from Lake Michigan. Maybe this could be an interesting question for some people, especially for the qnap engineers NOT updating the firmware to improve integration in an all-mac environment.The genus name Coregonus means angle-eye, and artedi refers to pioneering ichthyologist Petrus Artedi. What device (in this budget class) could an independent mac-experienced IT-manager suggest? But after reading this thread and other threads (all about the same AFP sharing problem), i'm seriously doubting if this is a good device in an all-mac lan.Įven this is a Qnap forum - they can just learn from it (and fasten up their AFP support) -, i can tell that competitors are Synology RS409 or 2nd-hand Xserve with intel.Īll three machines are about the same price, based on 2 Tb of total capacity (the Xserve being 3-4 years old, but still faster than any of the other brand new devices). ![]() Perhaps we need to raise it again in a new thread?įor all of you people posting comments on this thread it is too late: you have bought a qnap nas server.įor me, i am seriously looking for a rack-mountable, reliable and fast networked file server (and perhaps webserver, mediaserver, mailserver and even 'experiment' server) most likely in RAID5, and one of the possible devices was the qnap TS419U.
