Methods

This data set is a derived data set based on fishcatch data. Data are collected annually to enableus to track the fish assemblages of elevenprimary lakes (Allequash. Big Muskellunge.Crystal. Sparkling. Trout. bog lakes 27-02 [CrystalBog] and 12-15 [Trout Bog]. Mendota. Monona.Wingra and Fish). Sampling on Lakes Monona.Wingra. and Fish started in 1995; sampling onother lakes started in 1981. Sampling is done atsix littoral zone sites per lake with seine. minnowor crayfish traps. and fyke nets; a boat-mountedelectrofishing system samples three littoraltransects. Vertically hung gill nets are used toobtain two pelagic samples per lake from thedeepest point. A trammel net samples across thethermocline at two sites per lake. In the bog lakesonly fyke nets and minnow traps are deployed.Parameters measured include species-levelidentification and lengths for all fish caught. andweight and scale samples from a subset. Deriveddata sets include species richness. catch per uniteffort. and size distribution by species. lake. andyear. Dominant species vary from lake to lake.Perch. rockbass. and bluegill are common. withwalleye. large and smallmouth bass. northernpike and muskellunge as major piscivores. Ciscohave been present in the pelagic waters of fourlakes. and the exotic species. rainbow smelt. ispresent in two. The bog lakes containmudminnows. Protocol used to generate data:Gill net data have been standardized to a 24-hoursampling period. Assumptions used in thestandardization are available from theinvestigators. Day seines were only used in 1981and have been eliminated from this data set tomake sampling effort across years comparable.Number caught for each species is summed overrepetitions of a gear within a lake and over depthFor information on fish stocking by WisconsinDepartment of Natural Resouces in LTER lakes inDane and Vilas counties. seehttp://infotrek.er.usgs.gov/doc/wdnr_biology/Public_Stocking/StateMapHot...
