| Abstract | Globally, invasive non-native species (INNS), due to anthropogenic activities, are a form of aquatic pollution that severely affects the environment, ecological diversity, and economics. INNS are often unconstrained by competition and predation, exploit resources throughout their range, and thus continuously expand into vulnerable environments. Isolation attempts, targeted removal, and intentional fragmentation involve the use of deterrents and barriers in freshwater systems to control species movement and population expansion. Underwater acoustics is currently the only non-structural deterrent or attractant that can be agnostic or specific to a group of fish based on their hearing range, thereby reducing ecosystem impacts and risk to humans compared to other non-structural technologies. In addition, the costs to deploy and maintain underwater acoustics systems can be significantly lower than other options. An underwater acoustics deterrent system (uADS), along with an electrical deterrent, flushing, automated barge clearing deterrent, and dispersal bubble curtain, is proposed as a multi-deterrent system for Brandon Road Lock and Dam (BRLD; Joliet, Illinois, USA) on the Des Plaines River to control the spread of invasive carp. Herein, we will provide updates on the current deployments of uADS. Results of ongoing underwater acoustic research will help managers and stakeholders understand the effectiveness of uADS and, most importantly, provide considerations for introducing noise into an ecosystem and characterizing impacts on native species. |
