The purpose of this work was to instruct the students from the aquaculture engineering course of Federal University of Great Dourados – UFGD and make them pass along the information they’ve learnt at classroom to small farmers, not necessarily fish producers, but anyone who had any interest in the field. The project lasted for one year, and the visits to properties happened in the last semester of 2019. To make the conversation between producers and academics happen, nine properties were visited, all in Itamarati Settlement, located in the municipality of Ponta Porã – MS. In those locations were made analyses of water like, oxygen dissolved (mg L-1 ), pH, transparency (cm), temperature (ºC), alkalinity (mg L-1 ), total ammonia (mg L-1 ), toxic ammonia (mg L-1 ) and nitrite (mg L-1 ), and the academics explained to the producers how those parameters should stay, and how to check them, to get a sustainable fish production. To make it happen, some forms were left to the producers. It was noticed that the lack of information in field is a gap that has to be filled, so it’ll increase the fish production, with security and sustainability. The quality of water is one of the first subjects that should be analyzed before the installation of an aquaculture project, and the students that’ve taken part in this study, were able to convert words used in graduation to make it possible to teach the importance of periodical evaluations to activity enthusiasts.
