Annual food of bluegills from eight reaches on the San Joaquin and Merced rivers, and Salt Slough. Based on unweighted means (damp-dry biomass) of four total length classes ( 100 mm) of fish. Food in Relation to Environmental Characteristics Correlation analysis revealed that stomachs were fuller and contained a higher diversity of forage taxa in environments characterized by clear water, weak buffering capacity, and low levels of total P (Table 5). Bluegill stomachs were also fuller in areas with low conductivity and NH3-N concentrations. When the fullness and diet diversity indices were compared with the standing crop and diversity of benthic macroinvertebrates, only the two diversity indices were significantly correlated (r = , df = 7, P < .01)..
