N2 - The effect of four aeration rates: 0, 6, 12, and 24 hours/ day on the variation of chlorophyll a, zooplankton and benthos was evaluated in ponds stocked with yellowleg shrimp Penaeus californien-sis having low water exchange. Chlorophyll a, zooplankton and benthos varied significantly (P<0.05) over the time of culture. Abundance of zooplankton and benthic organisms showed significant (P<0.05) variations among treatments, being more abundant (P > 0.05) in the 6 and 12 hours/day aeration treatments. Some of the water quality parameters such as morning dissolved oxygen, organic matter, biochemical oxygen demand, and ammonia showed differences among treatments. Growth of shrimp was higher in the 12 hours/day aeration treatment. Yield and feed conversion ratio were higher in ponds receiving 6 and 12 hours/day aeration. Results of the study suggest that aeration has an effect on: biotic communities abundance; water quality parameters; and growth, yield, and food conversion ratio of shrimp.
