Fish farming is one of the zootechnical activities that has grown the most in recent years, especially in the Brazilian Amazon. The present study was carried out in the area of the State of Amazonas, one of the largest consumers of fish in Brazil, aiming at characterizing the production systems, the degree of severity of environmental impacts that this activity promotes and the different perspectives of future development in the different mesoregions of the state. Te investigations were carried out through the collection of secondary data provided by the Institute of Environmental Protection of Amazonas (IPAAM), which has 1,382 fish farms registered in its database. Tis information was organized by the state's microregion (center, south-west, north and south), exploring its main technical indicators, production infrastructures of young forms, size of enterprises and the degree of severity of environmental impact by size of fish farming . Te results obtained show that fish farming is practiced mainly for fattening of tambaqui for commercial purposes, carried out in terra firme structures (excavated nurseries and dams) in small flooded areas, with application of semi-intensive production system, being developed near (Manaus), due to its concentration of available logistical and infrastructure factors, with most of the projects classified as low severity of environmental impact.

Keywords : Colossoma macropomum; Amazónia; environmental law; semi-intensive; fishfarming.
