Distribution and Abundance of Larval Yellow Perch (Perca flavescens) in Lake St. Clair and the Lower St. Clair River, 2018

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.

Alumni Campground and the relationship with seasonal guests and wildlife
Tue, 12/17/2019 - 00:45
Abstract: For our capstone, we plan to focus on the wildlife and human interaction dynamics within Paul Smith’s College Alumni Campground. The objective of Owen’s section for capstone is too develop a ‘bear-awareness’ program for the Alumni Campground. Katie is looking into establishing a wildlife management plan of the campground correlating with the evidence of determining where there are patterns of travel within the campground of the local wildlife.
