The present research about existing experiences of Aquaponics Systems in the State of Pará, municipality of Bragança. Among the main reasons for conducting the study was aim alternative paths to aquaculture activity in Brazil to meet the growing demand for healthy foods, mitigating the indiscriminate use of water resources and the lack of treatment and dumping inadequate effluent. In this sense, the aquaponic presents itself as an alternative to the integrated production of aquatic organisms (fish, crustaceans and algae) and vegetables with the benefit to save natural resources. The research aims General Aquaponics analysis, in the social and environmental context, from the studies and experiences that exist worldwide, national, as well as in the immediate region of Bragança, Pará State, with the purpose of drafting a guide for socialization and dissemination of aquapônica technology. Based on studies of the main bibliographic references on the aquaponic and the most important experiences of Aquaponics systems in the municipality of Bragança were analyzed by checking the theoretical and practical insights of those involved, and the potential and limitations of productive activity. For the preparation of the guide used the data provided in the bibliography, as well as those purchased on the spot. The results showed a bibliographic shortage issue in Brazil, mainly in respect of the economic viability of the activity, demonstrating clearly the necessity of deepening in the studies. The research showed that there is a strong tendency for membership of the local farmers to the aquapônico system of production, largely due to increasing income generation and low environmental impacts of this type of production.

Aquaponia: uma ferramenta didática de ensino no IFPA-Santarém, Brasil
(Universidade Federal do Pará, 2020-04-06) PAULA, Carla da Silva; SILVA, Luiz Rocha da; http://lattes.cnpq.br/0951402055398517; BARBOZA, Roberta Sá Leitão; http://lattes.cnpq.br/9331256487699477; https://orcid.org/0000-0003-2367-553X
Aquaponics has gained prominence as an important sustainable agrifood technology, this system incorporates both the production of plants and fish in a symbiotic relationship between these two components and the microorganisms present in the environment where the residual nutrients from fish farming are modified by bacteria into substances that can be absorbed by plants favoring their development. Thus, the use of aquaponics during classes incorporates knowledge of a variety of subjects from biology, physics, mathematics, agriculture, sanitation, engineering, technology and nutrition. This work aims to understand how the use of a sustainable aquaponics system can contribute as a teaching tool in the teaching practices of teachers at IFPA - Campus Santarém. To achieve the objectives proposed in this research, we used as methodology a semi-structured questionnaire with open and closed questions, analysis of the subjects' menus, in addition to a bibliographic review on the subject. The target audience of this research were nine professors from the IFPA-Campus Santarém who had some of their theoretical or practical activities using the aquaponics system as a teaching tool. The analysis of the data allowed us to realize that the use of aquaponics provides teachers with a more enriching teaching dynamic, capable of uniting practice and theory in an interdisciplinary way, even if it occurs in a less intense way, teachers pointed out the importance of using sustainable technologies in vocational training, highlighting the use of aquaponics as a positive ally in enriching the training of students in integrated education.
