Fall diet and bathymetric distribution of deepwater sculpin (Myoxocephalus thompsonii) in Lake Huron

Diet shifts by planktivorous and benthivorous fishes in northern Lake Michigan in response to ecosystem changes

“…Size occurred since the Diporeia decline have indicated that the diets of both sculpin species can be dominated by Mysis, while Diporeia will still be consumed in the regions where it remains present (e.g., French et al, 2010;O'Brien et al, 2009). The only major difference between our results and previous studies was that slimy sculpin diets were more diverse (but see .…”

Mercury biomagnification and contemporary food web dynamics in lakes Superior and Huron

“…Deepwater sculpin likely compensated for this loss by incorporating Bythotrephes in their diet (O'Brien et al, 2009). Bythotrephes prey excessively on herbivorous Cladocerans and tend to exhibit elevated δ 15 N values in this lake (e.g., + 8‰, Jackson et al, 2013).…”

Feeding selectivity of slimy sculpin Cottus cognatus and deepwater sculpin Myoxocephalus thompsonii in southeast Lake Michigan: Implications for species coexistence

“…Slimy and deepwater sculpin appeared to exploit opposite ends of the Diporeia size continuum, with deepwater sculpin selecting larger Diporeia than slimy sculpin. This may be important for mediating interspecific competition because Diporeia represents a significant fraction of the diet biomass of both sculpin (Wells, 1980;Wojcik, et al, 1986;Selgeby, 1988;Hondorp et al, 2005;O'Brien et al, 2009;French et al, 2010). Consequently, slimy and deepwater sculpin may reduce diet overlap even when alternate prey types are unavailable.…”
