Examining Fisheries Impact of Invasive Lionfish with an Ecopath with Ecosim Model

Assessing management options to reduce lionfish impacts on reef ecosystems.

Ecological and Economic Impacts of Land-Use and Climate Change on Coastal Food Webs and Fisheries

The Suwannee River estuary supports several imperiled species, multimillion-dollar fisheries, aquaculture, and tourism in Florida’s Nature Coast. This project will assess how past, present, and future climate and land use scenarios influence the quality of natural resources in the Suwannee River estuary. The team will develop a predictive model to evaluate different watershed management actions, based on water quality and nutrient flow. These predictions, combined with food web modelling, will project how changes in freshwater quality and quantity will influence fish and shellfish populations. Results from the watershed and food web models will also be combined with survey data to evaluate the economic impacts of different land use and climate scenarios.
