TEST OF PHEROMONE TRAPS TO CAPTURE THE INVASIVE ROUND GOBY

We propose to develop and test a pheromone trap that targets the  invasive round goby fish (Neogobius melanostomus), resulting in a  reduction in their abundance in critical habitats (i.e. spawning and  nursery areas for native species or species-at-risk) or limiting and  possibly preventing their spread into new waterways. The project  builds on the hypothesis that the reproductive male round goby  releases a sex attractant to which gravid females respond.  We will  1) compare the response of gravid female round gobies to  reproductive male odour when males have been exposed to sight and  smell of males;  2) conduct a dose response experiment of gravid  females to increasing concentrations of males; 3) determine odour  preferences of round gobies in a large static arena (an above ground  pool); 4) compare the effectiveness of traps seeded with different  odour types in capturing gravid female round gobies in a lake; and   5) begin to develop a time-release tablet, examining the dissolution  profile and incorporation of pheromone into a tablet. These  experiments provide the background development for a potential  benign management tool that has the potential to capture gravid  female round gobies. Effective control (local reduction in  abundance) of the round goby will benefit important sport and  commercial fishes, species at risk, biodiversity, and may limit  (delay or prevent) the spread of the round goby into new waterways.  The outcome of this research can be applied to other invasive  organisms.
