Invasive species: The rusty crayfish

My summer research project focuses on finding a possible solution to manage and control the spread of the rusty crayfish throughout aquatic systems. Rusty crayfish, once introduced, displace native crayfish and make drastic changes to the aquatic environment. These changes include destroying aquatic plants, which serve as shelter for young fish, habitats for invertebrates, and so on. They also create an additional pressure for fish species by eating fish eggs. Thus, my project focuses on creating a mathematical model to assess different control strategies, including trapping, increasing predation, and trawling, to determine which method(s) would be the most effective at relieving the rusty crayfish’s impact on aquatic ecosystems.
