Abstract: Effects of populations of Cyprinodon macularius Baird and Girard (desert pupfish) and Gambusia affinis affinis (Baird and Girard) on aquatic insects and zooplankton were investigated in shallow ponds clear of emergent vegetation and those planted with rice. Presence of both fish caused equivalently lower densities of beneficial insect predators, mosquitoes, and zooplankton.
