Abstract

The article focuses on evaluating chemical decontamination methods for angling gear to simultaneously control two aquatic invasive species (AIS) in the Laurentian Great Lakes region: New Zealand mudsnails (NZMS, Potamopyrgus antipodarum) and the diatom didymo (Didymosphenia geminata). Laboratory experiments tested the effectiveness of two household cleaning products—full-strength Formula 409 and 5% Dawn dish detergent—applied by soaking or spraying for 10 or 20 minutes. Results showed that soaking gear in Formula 409 caused 100% mortality of NZMS and significantly reduced didymo photosynthetic activity, while dish detergent was effective against didymo but not NZMS. Given practical considerations, the study recommends liberal spraying of Formula 409 on wading gear with a 10-minute wait before rinsing as a feasible method to minimize the spread of both invasive species.
