Food Web Ecology Field Assistant

Employer: Ben Martin(bemartin@wisc.edu)

Description:

Spiny water flea (Bythotrephes longimanus) is an invasive zooplankton that’s spread across several Wisconsin lakes and heavily prey upon native zooplankton communities. Spiny water flea have a long caudal spine with several spines that make them difficult to consume, and therefore can be problematic for planktivorous fish and young life stages.

This project is focused on the potential to manage spiny water flea from the top-down through fish predation. To do so, we will be comparing the foraging behavior of various fishes in relation to native prey and spiny water flea.
