A multi-sensory approach to targeted management strategies for the round goby (neogobius melanostomus)

圆虾虎鱼已经成为五大湖地区的优势物种，在历史上一直是受欢迎的和有利可图的休闲钓鱼活动。这种入侵威胁着数百万美元的休闲捕鱼业，并影响了本地鱼类的生存。随着圆虾虎鱼种群向内陆水域和河流的扩张，这种破坏将继续蔓延。为了保护运动鱼类和本地鱼类的繁殖地，我们提出了一种有针对性的方法来控制特定敏感区域的圆虾虎鱼，通过开发一种利用信息素和发声的多感官策略来吸引雌性圆虾虎鱼进入陷阱。拟议的研究将确定一种信息素的化学结构，这种信息素释放在筑巢雄性的尿液中以吸引雌性，将定义这种信息素在筑巢雄性中的传播，并将评估将这种信息素的传播与筑巢雄性发出的叫声相结合的效果。这项研究将由一群经验丰富的化学家和生物学家进行，与国际专家进行咨询和合作，并与安大略省自然资源部（OMNR）合作。

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).
