Abstract
Yellow perch (Perca flavescens) are a recreationally important species and represent a key ecological component of glacial lake littoral fish assemblages (Stone 1996, Blackwell et al. 1999). Research has shown a generalized pattern of juvenile (age-0) yellow perch spatial distribution wherein larvae hatch in near-shore areas, migrate to limnetic areas where they remain for approximately 40 d, and then return to demersal behaviors and within near-shore littoral habitats (Noble 1975, Whiteside et al. 1985). However, anomalous distribution and habitat use by age-0 yellow perch has been observed in South Dakota glacial lakes (Fisher and Willis 1997) and the spatial distribution and habitat association of post-larval (>25 mm) age-0 perch is largely unverified in northern Great Plains glacial lakes. Herein, we report the depth distribution and near-shore (0–2 m depth) habitat association of post-larval, age-0 yellow perch (hereafter referred to as age-0 yellow perch) in two northeastern South Dakota glacial lakes.
