A probabalistic representation of fish diet compositions from multiple data sources: A Gulf of Mexico case study

Ecosystem models can be extremely useful tools for ocean resource managers to determine how commercial fisheries can respond to a specific management strategy. C-IMAGE researchers out of the University of South Florida with colleagues from the Florida Fish and Wildlife Conservation Commission looked at fish diet for two non-commercially relevant species in the Gulf of Mexico to produce Maximum Liklihood Estimates (MLEs).  MLEs describe how much a specific prey item constitutes a predator's diet.  These values are used to produce a food web diagram that is ultimately used to fine tune the Atlantis ecosystem model.

Podcasts from The Loop

The Loop is a series of podcasts which take an in depth look at C-IMAGE research. Partnering with Mind Open Media reporters Ari Daniel Shapiro and David Levin, our researchers share the importance of their studies and how they help our understanding of oil spills. David and Ari have produced eight podcasts and have more in the queue. The podcasts are linked below. Plug in and learn about our research!
