Abstract

The primary objective of this research is to find out the relationships between key environmental variables affecting fish species abundance in small streams in Western Michigan. The environmental variables that were collected are water temperature, percent macrophyte cover, substrate composition, amount of woody debris, water conductivity, mean stream depth and mean stream width. The fish species studied are brown trout (Salmo trutta), central mudminnow (Umbra limi), bluegill (Lepomis macrochirus), creek chub (Semotilus atromaculatus) and white sucker (Catostomus commersonii). The environmental variables were measured along a 150 m stretch at eleven transects. Within each stretch the fish were collected using an electro-backpack fishing technique. I expect to find a correlation between fish species presence and environmental variables present.
