Fish culture is perhaps one of segments in animal production with high increasing rates worldwide. However, water quality is a concern due to problems in production and low profits when it is below standard. Current study focuses on water quality based on limnological variables in fish ponds for the rearing of Colossoma macropomum (tambaqui) in sequential supply. Results show that rainfall regimes and management during the production cycle affected the evaluated parameters. Research occurred between August 2013 and July 2014. Further, pH, ammonia and nitrate rates complied with Resolution by CONAMA 357/2005; alkalinity and temperature complied with fish farming standards, contrary to most dissolved oxygen and total phosphorus rates. Electrical conductivity in fish ponds in August 2013, the month with the lowest rainfall indexes in the region, was higher than rates established by CONAMA 357/2005. The density of the phytoplankton community significantly increased in October 2013, with sparse blooming, but featuring low transparency and dissolved oxygen in all fish ponds. Results show the need for systematic introduction of Good Management Practices to improve environmental quality and contribute towards the sustainability of fish farm culture.
