ABSTRACT. Biologists commonly use Zote<sup>TM </sup>soap as bait in tandem hoop-nets to effectively sample for channel catfish Ictalurus punctatus. Previous studies suggest that Zote<sup>TM </sup>soap is effective in reducing aquatic turtle-bycatch. This is crucial due to the high mortality rate of aquatic turtles as bycatch for both hoop nets and trotlines. However, there are very few studies that have been done to evaluate aquatic turtle bycatch on Zote<sup>TM </sup>soap baited trotlines. Additionally, no studies have evaluated the effectiveness of different colors of Zote<sup>TM </sup>soap to assess catch rates of both channel catfish and aquatic turtle bycatch. Our trotlines will be set overnight, soaking for twenty-four hours, on the Monongahela River. Each line will consist of twenty-five 2/0 sized hooks. Each hook will be baited with a piece of Zote<sup>TM</sup> soap that is approximately the size of a nickel. To eliminate a bias in color, each hook will be randomly assigned a specific Zote<sup>TM </sup>soap color, which will consist of either: pink, white, or blue. Preliminary data suggest that pink Zote<sup>TM </sup>Soap is more efficient and effective than white or blue Zote<sup>TM</sup> soap. Our sampling sites will be determined by randomly selecting areas with large scale river features or macrohabitats (i.e., main channel, inlet, and backwaters) in the Monongahela River. During our study we seek out to determine if sampling with Zote<sup>TM </sup>soap baited trotlines will effectively sample channel catfish populations while also reducing aquatic turtle bycatch and evaluate the catch rates of multiple colors of Zote<sup>TM </sup>soap.
