In the present study, a limnological evaluation on grow-out ponds of Macrobrachium amazonicum subjected to different feeding rates and forms of harvest management was performed. Twelve 0.01-ha earthen ponds were stocked with 20 juveniles.m-2. Three of these ponds were supplied with 3%, three with 5%, and three with 7% of prawn biomass. Three remaining ponds were supplied with 5% of prawn biomass and subjected to selective harvest. Sixteen water and effluent parameters were monitored weekly, namely, dissolved oxygen, biochemical oxygen demand, pH, total alkalinity, electrical conductivity, nitrate-N, nitrite-N, ammonia-N, soluble phosphate, total phosphate, chlorophyll a, chlorophyll b, chlorophyll c, pheophytin, total dissolved solids and turbidity. Our data suggest that the different feeding rates and types of harvest do not play a significant role in pond ecology and, therefore, possibly intrinsic characteristics of each pond could be greatly influencing the quality of the water. 2009 artículo científico 1415-6938 https://www.redalyc.org/articulo.oa?id=26015684002 es http://www.redalyc.org/revista.oa?id=260 Ensaios e Ciência: Ciências Biológicas, Agrárias e da Saúde application/pdf Kroton Educacional S.A.
