Spatial Genetic Structuring of Forage Fish in the Upper Great Lakes: Evidence for a Subdivided Forage Base and Implications for Structuring in Predatory Fish Species

Alewife, smelt, sculpin and bloater have something in common:   together with several other species, these fish comprise what's   known   as the forage base in the upper Great Lakes. As such, they provide   meals for important predatory fish such as lake trout and salmon.   This study will use genetic testing to identify the movement and   distribution of forage fish to better understand the relationship to   top predator populations. Researchers will also identify the   relative   importance of ecological and physical environmental factors   underlying fish community structure.
