SUMMARY:

The tambaqui (Colossoma macropomum) is the second largest freshwater scale fish in South America. The production of tambaqui is widespread, mainly in the north, northeast and central-west regions of Brazil due to its hardiness and easy adaptation to extreme conditions of water quality. The duration of the production cycle, which varies from 8 to 12 months, depends on the stocking density, type of food and water quality. The cultivation of vegetables integrated with fish farming makes it possible to reuse water for the production of vegetables and to remove excess nutrients from fish production. Water quality in aquaculture is characterized by the dynamic balance of all physical, chemical and biological variables, which make it possible to cultivate aquatic organisms, minimizing environmental impacts and enhancing production. The objective of this work was the production of tambaqui associated with the cultivation of jambu (Acmella oleracea), as a tool for absorbing and reducing ammonia. Four raised tanks were built, in circular shape with a capacity of 20 m3 of water, each tank received 500 tambaqui fingerlings fed a diet based on commercial feed with 32% protein. Two groups with two replicates each were used, two experimental and two controls. The water quality parameters (pH, oxygen and temperature) were manually monitored with portable devices and the nitrogenous compounds were monitored weekly by photometry. Fish biometry was performed fortnightly for four months. Through this research work it is intended to evaluate the efficiency of jambu as a possible ammonia reducer that tends to be a beneficial factor for the growth of tambaqui in psiculture.
