讲座摘要

Recent research on the interactions between parasitic sea lice and wild and farmed salmon in the Broughton Archipelago of British Columbia, Canada has underlined the need to better understand the role that physical oceanography plays in the development, behaviour and movement of these lice. In this talk we will describe a model that simulates both the dispersion of lice eggs originating on salmon farms and their development through the nauplii and copepodid life stages. This biological model is coupled to a finite volume circulation model that provides the four-dimensional salinity, temperature and velocity fields that control movement and growth/mortality. A three week simulation for March 2008 will be evaluated against available observations and the utility of these coupled models in helping to design a coordinated aquaculture management plan in 2009 will be briefly discussed.
