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

圆虎鱼已经成为五大湖中的优势物种，在历史上，这些地方一直是休闲钓鱼的热门和有利可图的地方。这种入侵威胁着价值数百万美元的休闲捕鱼业，并影响了当地鱼类的生存。随着圆形虎鱼种群向更多内陆水域和河流的扩张，这种损害将继续蔓延。我们建议通过在特定敏感地点开发一种有针对性的生物控制圆虎鱼的方法来保护运动和本地鱼类的繁殖地，通过开发一种带有信息素和发声的多感官策略来吸引雌性圆虎鱼进入陷阱。这项拟议的研究将确定筑巢雄性尿液中释放的用于吸引雌性的信息素的化学结构，将确定这种信息素通过筑巢雄性的传播，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以引诱雌性的效果。这项研究将由一组经验丰富的化学家和生物学家进行，并与安大略省自然资源部(OMNR)合作，咨询国际专家的意见并进行合作。

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).
