Research Project: Conservation Effects Assessment Project (CEAP) 2017 - Benchmark Watershed Assessment Studies (on croplands)

Location: National Soil Erosion Research

Project Number: 5020-12130-003-20-I
Project Type: Interagency Reimbursable Agreement

Start Date: Jul 31, 2017
End Date: Sep 30, 2019

Objective:
Quantify how conservation practices affect water quality, riparian habitat and fish community in drainage ditches at the St. Joseph River CEAP Watershed.

Approach:
Use biochemical, physiological, and morphological biomarkers as indicators of sublethal responses of selected fish species from exposure to agricultural contaminants within the St. Joseph River CEAP study sites. Conduct in situ assessment of physicochemical variables (dissolved oxygen, pH, turbidity, conductivity), and physical habitat (water depth, velocity, substrate types) and relate the habitat information, water quality data to fish community structure (species richness, abundance, evenness, percent insectivores, percent omnivores) in agricultural drainage ditches.
