In 1997, a total of 340 alewife stomach samples were obtained from adult alewife in Lake Michigan during 6 nights of sampling. Index stations were added to the Michigan shoreline, where none existed before to improve the utility of YOY abundances as a predictor. In general, Lake Michigan females had vitellogenin levels comparable to males. They were compared with the relative efficiencies of beach seines and bottom trawls, the two most commonly used types of gear, so that all agencies can contribute to lake-wide abundance data. Endpoints included stage and histopathology of ovaries and testes, plasma hormones and vitellogenin, liver mixed-function oxygenase activity (EROD), indicators of pollutant exposure, and other parameters.

In addition, several other studies have been conducted, including an alewife stomach content study, a lake-wide mark and recapture study and a reproductive status study.
Yellow perch from Lake Michigan and a reference site, Lake Mendota Wisconsin, were collected in winter 1996, at spawning in 1997 and in fall 1997. The majority of YOY perch were captured in the 12 mm stretch mesh with few in the larger mesh sizes, so since 2009, we have used only the 100-foot-long nets in 12 mm stretch mesh. These assessments include 1) egg deposition, 2) spawning, 3) young-of-the-year (YOY) and 4) winter graded-mesh. They inhabit all the Great Lakes, with greatest Michigan concentrations in Lake Erie, Lake St. Clair, Saginaw Bay, the eastern end of the U.P. Perch spawn in the spring, laying eggs in gelatinous strings over dense vegetation, roots, and fallen trees in the shallows. Numbers of yellow perch caught during the winter graded mesh gill net assessment have declined to record lows in recent years.
(Native Fish) Two dorsal fins separated into a spiny and soft-rayed portion, yellow sides, seven blackish bars on the sides, no canine teeth.Yellow perch have the distinction of being the most frequently caught game fish in Michigan perch travel in schools, generally preferring relatively shallow waters near shore. In 1998, divers searched for 12 hours and 48 minutes and found 0 egg masses or 0.0 egg masses per 1000 square meters. No larval fish were found in any of the alewife stomachs. Although a number of yellow perch tagging projects have been conducted in Lake Michigan and its embayments in the past, these efforts were conducted independently of one another, and only one was known to have included an objective to estimate perch abundance. The major objectives of the winter graded-mesh assessments are to assess the year-class strength, sex ratio, age, growth and mortality of the yellow perch population in Lake Michigan. The sex organs of a fish can be examined to indicate how ready the fish is to spawning, also referred to as their reproductive status.

This location provides visitors with excellent fishing, and a unique camping experience, with many of the spacious sites having lake access. The updates come from a combination of creel clerks and other DNR staff around the state and reflect past fishing conditions over the last seven days. In 2016 we set at two additional sampling locations in Milwaukee County, off of St. Francis (south of the Milwaukee Harbor) and off of Bradford Beach (north of the Milwaukee Harbor).
