Distribution and Abundance of Larval Yellow Perch (Perca flavescens) in Lake St. Clair and the Lower St. Clair River, 2018
Mon, 12/02/2019 - 21:23
Abstract: Spatial and temporal dynamics of fish larvae play an important role in determining year-class strength due to variation in habitat quality and food resources that influence larval growth, development, and survival rates. Surveys conducted during the past decade in the St. Clair-Detroit River System have revealed a decline of yellow perch. Genetic and microchemistry analyses showed that these fish make a substantial contribution to the yellow perch stock in western Lake Erie. Our study examines the spatial and temporal distributions of larval yellow perch in Lake St. Clair and the lower St. Clair River to identify important spawning and nursery areas and other ecological factors influencing their early life history. We employed a lake-wide daytime sampling program in 2018 using paired bongo nets to sample pelagic larvae throughout 33 sample locations beginning in mid-March before yellow perch had hatched and continued through mid-July when larvae were absent from samples. Based on our spatial analysis results, Mitchell Bay and Anchor Bay appear as the primary regions for yellow perch spawning habitat and/or nursery grounds for larvae. It is difficult to conclude which factors are influencing the distribution of yellow perch the greatest, but submerged aquatic vegetation, water temperature and clarity likely influence yellow perch vital rates, based on our study. The results from this study give us a growing understanding of the ecological interactions underlying larval yellow perch and their habitat usage during their early life history.

Proposal for Improvements to Alumni Campground Waterfront
Sat, 12/14/2019 - 15:42
Abstract: The Alumni Campground is full of potential. A front country campground in close proximity to many great wilderness experiences. Some of those experiences can be best reached by water and yet the Alumni Campground waterfront is not much more than a single “No Swimming” sign nailed to a tree. This lack of infrastructure has caused degradation of the shoreline as the user base for water craft does use the campground as a starting point for excursions onto the St. Regis waterways but due to a lack of durable launching sites they have created several eroded and denuded spots along the lakes bank. In order to accommodate the amount of use this asset receives and prevent further degradation this proposal is designed to give the Alumni Campground Committee a sensible set of options for structural improvements designed to suit the user bases needs and protect the valuable waterfront resources.
