My research involves using mathematical models to determine how to reduce the impact of the macroparasite Argulus foliaceus in UK stillwater trout fisheries. Specifically, I'm looking at how the parasite population responds to different stocking levels and methods, and how the impact of the parasite can be reduced by combining the existing treatments with an optimal stocking procedure.
In my first year I produced a literature review which outlined the problems caused by Argulus spp. in the UK, the current methods of control, and a summary of the parameters required to produce an accurate model of Argulus spp. systems. I have now written and analysed several models featuring different stocking methods used in fisheries across the UK, and incorporated seasonality and chemical treatment with emamectin benzoate. I am currently writing up my results, and investigating the impact of reservoir hosts and egg-laying boards on the system.
