The round goby has become a dominant species in the Great Lakes at sites that have been historically popular and profitable for recreational fishing of sport fish. This invasion threatens the multi-million dollar recreational fishing industry, and has impacted the survival of indigenous fish. This damage will continue to spread with the expansion of round goby populations to more inland waters and rivers. We propose to protect the breeding grounds of sport and indigenous fish by developing a targeted approach for biological control of the round goby in specific sensitive locations, by developing a multisensory strategy with pheromones and vocalizations, for attracting female round gobies into traps. The proposed research will identify the chemical structure of a pheromone released in the urine of nesting males for attracting females, will define the dispersal of this pheromone by nesting males, and will assess the efficacy of combining the dispersal of this pheromone with calls emitted by nesting males for luring females. This research will be carried out by a group of experienced chemists and biologists, with consulting input and collaboration from international experts and in partnership with the Ontario Ministry on Natural Resources (OMNR).

圆虾虎鱼已成为五大湖的优势物种，这些地方历史上一直很受欢迎，并且是休闲钓鱼的有利可图的地点。这种入侵威胁到数百万美元的休闲渔业，并影响了土著鱼类的生存。随着圆虾虎鱼种群向更多内陆沃茨和河流的扩张，这种破坏将继续蔓延。 我们建议通过开发一种有针对性的方法，在特定的敏感地点的圆虾虎鱼的生物控制，通过开发一种多感官的策略与信息素和发声，吸引女性圆虾虎鱼进入陷阱，以保护运动和土著鱼类的繁殖地。 拟议的研究将确定一种信息素的化学结构释放在尿液中的筑巢男性吸引女性，将定义这种信息素的传播筑巢男性，并将评估结合传播这种信息素与呼叫筑巢男性发出引诱女性的功效。这项研究将由一组经验丰富的化学家和生物学家进行，国际专家的咨询意见和合作，并与安大略自然资源部（OMNR）合作。
