Dr. Tom Ihde is a fisheries ecologist at PEARL with research interests that focus on ecosystem based fisheries management (EBFM) of the Chesapeake. Specifically, Tom has developed a range of ecosystem modeling tools (applying mainly the Atlantis modeling approach and Ecopath with Ecosim) that integrate the best available information available for the Chesapeake environment, to predict the effects of the major stressors and changes in this system on our harvested populations like oysters, striped bass, and blue crab. The effects of factors that Tom has focused on to date include: nutrient management (the USEPA's TMDL, i.e., "Total Maximum Daily Load" requirements for the jurisdictions in the Bay watershed), habitat loss (submerged aquatic vegetation, and marsh), habitat restoration (oysters), and invasive blue catfish.

A key aspect of making EBFM a reality for the Chesapeake, is connecting fish population forecasts to the effect of those forecasts on our fishing communities and on the larger economy of the region. Providing such information to our decision-makers is critical to support sound and sustainable science-based policy. Tom is working to make these connections, and to provide policy-relevant science by collaborating with Dr. Scott Knoche, Senior Research Economist at Morgan.

Tom also has a long history of working with the Chesapeake Bay Program, and is a member of its Scientific and Technical Advisory Committee, as well as a wide variety of fish- and habitat-related workgroups.
