“…Studies have evaluated other non‐physical barriers, such as light (Hamel, Brown & Chipps, ), sound (Taylor, Pegg & Chick, ; Vetter, Cupp, Fredricks, Gaikowski & Mensinger, ) and bubbles (Zielinski et al., ), to combat invasive fish species, with the understanding that combinations may be more effective than a single modality (Popper & Carlson, ; Welton, Beaumont & Clarke, ). For example, Atlantic menhaden, Brevoortia tyrannus (Latrobe), spot, Leiostomus xanthurus (Lacepède) and white perch, Morone americana (Gmelin) demonstrated greater avoidance of strobe lights combined with bubbles compared to either stimulus alone (McIninch & Hocutt, ).…”
