The figure shows that the longer lake trout in Blue Mesa Reservoir were very, very fat in 2000, 2001, 2002, and 2006 when their primary food sources were plentiful. Yet the fatness bottomed out in 2009 when they were overpopulated and decimated their food sources. Efforts to thin the herd are starting to be successful and the longer fish were fatter in 2010 and 2011, because their food sources are rebounding in response to reduced predation.
A similar analysis for species in the Calcasieu Estuary would be tremendously informative.
