Anthropogenic Interactions – Invertebrate Fisheries & Aquaculture
Fisheries and aquaculture are important marine activities that provide marine-derived food resources and jobs in coastal communities. Responsible management of these industries requires understanding how fishery and farm practices interact with coastal ecosystem processes.
In British Columbia Canada, I worked on shellfish farms to examine how farm operations interact with larval recruitment. These clam farms are located on intertidal mudflats, where I characterized small-scale flow environments and patterns of larval recruitment around aquaculture structures, to test their influence on larval settlement processes1.
Fisheries management decisions can also influence the way that populations are connected and ultimately impact wild stock genetics. I have used individual-based models to simulate and study genetic connectivity over a range of possible oyster fishery management and marine protected area strategies, the results of which will develop a greater understanding of the effects of management decisions.
