Abstract

Physical parameters, densities and sizes of two species of freshwater shrimps (Atya lanipes and Xiphocaris elongata) in four headwater streams (Quebrada Prieta, Toronja, Bisley 3 and Bisley 5) have been censused 2 times yearly since 1998 to determine the effects of predatory fishes on shrimp size and spatial distributions of pools relative to locations of waterfalls.
