Discovery Park Undergraduate Research Internship Program

"FILLED - Reproductive ecology of yellow perch"

About the Project

Project Time & Type:
Summer 2014 - DURI
Research area(s):
Project Description:
Similar to a variety of aquatic animals, yellow perch produce a gelatinous ribbon (skein) around their eggs for protection. Yellow perch skeins have been observed protecting unhatched eggs from infection and, potentially, from predation. It has not been directly studied if predators simply prefer other eggs or if the skeins directly deter predators. To examine this question further, this project will determine if common egg predators, round gobies and crayfish, will consume yellow perch eggs in or out of a skein when the choice of walleye eggs is also available.
Expected Student Contributions:
The student intern will be responsible for helping set up and run the experiment, organize and analyze data, and prepare and present the results. Successful applicants will have a strong interest in ecological research and be able to work well in a team as well as independently.
