Response of Yellow Perch Diet to a Changing Forage Base in Southern Lake Michigan, 1984–2002

Diets of Yellow Perch (Perca flavescens) in Wetland Habitats of Saginaw Bay, Lake Huron

“…Truemper et al (2006) also found that yellow perch in southern Lake Michigan were generalist piscivores. However, age-1 yellow perch did seem to show limited preferences for amphipods and trichopteran invertebrate prey and seemed to avoid gastropods and hemipterans.…”

Re-engineering the eastern Lake Erie littoral food web: The trophic function of non-indigenous Ponto-Caspian species

“…Johnson et al (2005) found that round goby contributed roughly a quarter of Lake Erie's yellow perch's total diet each year since 1998, and that benthos, zooplankton, and small fish also were important. Yellow perch became increasingly piscivorous at larger size in southern Lake Michigan, but the prey species consumed changed with availability between 1982 and 2002, as perch switched from alewife and rainbow smelt to round goby (Truemper et al, 2006). It is interesting to note that all of those prey species are NIS, emphasizing the opportunistic dietary flexibility of the yellow perch.…”

Effects of source–sink dynamics on harvest policy performance for yellow perch in southern Lake Michigan

“…There is some evidence such compensation exists (Dettmers et al, 2005), but post-recruitment cannibalism may also be important. Truemper et al (2006) found that small yellow perch were common diet items of larger yellow perch, and such cannibalism likely occurs after juveniles settle to demersal habitat because larger yellow perch generally feed demersally (Tyson and Knight, 2001).…”
