Home Table 40. Summary of Hudson-Raritan Estuary silver hake diet by sampling period during 1996-97, expressed as the percent frequency of occurrence of dominant prey or items (FO), and as the mean percent contribution of dominant prey or items to total stomach content volume (TV). (n = sample size; ES = percent of empty stomachs.)
