Alimentary diagrams obtained plotting both freshwater shrimp abundance and occurrence for 5 selected species divided per sampling season (au = autumn; wi = winter; sp = spring; su = summer) and year, and standard length range in cm. The remaining fish species showing few data or an occasional occurrence of P. antennarius were excluded in this analysis. Since we would not evaluate fish species diet overlap, only the shrimp components found inside the stomachs were shown in the Amundsen et al. (1996) graphic outputs.
