In this article it was demonstrated the importance of visual management of the enterprise to meet the priorities of work, uninterrupted production and commissioning. With the use of the tools of automation projects, the identification performed, subsidizing the planning teams for programming services, advocating the optimization of costs and deadlines.

The Brazilian fish farming in Federal reservoirs is being discouraged by the country's current legal system due to the bureaucracy and the involvement of many agencies.
