Gastric Evacuation Rates of White Perch, Morone americana, Determined from Laboratory and Field Data

Synopsis
Gastric evacuation rates (R) of white perch, Morone americana, were determined in laboratory experiments and by using field data. The resulting relationship of R and temperature (T) for white perch was R = 0.028e^0.106T(r² = 0.98). The high r² of the regression indicates good agreement of the combined laboratory and field data. Our rate compares well with those available for other species; and especially for Eurasian perch, which has a similar thermal existence to white perch in Lake Erie.
