Round Goby and Mottled Sculpin Spawning Interactions

admin
Project
In progress
OBJECTIVES: (1) Determine whether round gobies interfere with mottled sculpin spawning. (2) Compare/contrast nest site selection in round gobies and mottled sculpins to find ways in which habitats can be modified to minimize round goby reproduction while protecting/enhancing mottled sculpin reproduction.

Introduction of Alien Aquatic Species in the St. Lawrence River and Impact on Biodiversity

admin
Project
In progress
This project is part of a biodiversity conservation strategy and its purpose is to design and implement the tools needed to: 1) Prevent the introduction and transfer of non-native aquatic species; 2) Control the propagation of invasive non-native species; 3) Assess the impacts of introduced species on biodiversity.

Project
In progress
This agreement provides funds to the US Geological Survey to undertake a focused assessment of current Lake Ontario benthic communities as associated with both physical and biotic factors in areas where Diporeia is no longer present and areas where they continue to be abundant.

Aquatic Nuisance Species: Effects of Invasive Invertebrate Predators on the Food Webs of the Great lakes--IL/IN Component

admin
Project
In progress
We are using a variety of techniques to assess the food-web  consequences of exotic zooplankton species in the Laurentian Great  Lakes. In the past 15 years, two exotic invertebrate predators,  Bythotrephes (the spiny water flea) and Cercopagis (the fish hook  flea), have invaded the Great Lakes.

Integrated Barriers for the Control of Juvenile Exotic Fish

admin
Project
In progress
The project will investigate the role of juvenile life stages in the dispersal of two Great Lakes invasive species, bighead carp and round goby.  Since juveniles of many fish species are the main vectors of colonization, the objective of this project is to gain information on the likely speed of invasive fish dispersal by voluntary migration.

Aquatic Nuisance Species Anglers Monitoring Network

admin
Project
In progress
This project will serve to help in implementation of a rapid response plan for introductions of new aquatic nuisance species.  Monitoring is a key component of rapid response, and this project will utilize the eyes of anglers who already in the field in a variety of locations.  An information system will be set up to inform anglers to watch for
