The study area comprised the beaches of Atalaia, Farol Velho, Maçarico, Corvina and Marieta beach, located in the municipality of Maracanã. For the collection of zooplankton, vertical drags were carried out using a plankton net (180 µmmesh) at 4 m depth, in the months of February, April, June, August, October and December, also measuring physical- water chemicals (salinity, pH, electrical conductivity, dissolved oxygen, temperature and atmospheric pressure). It was possible to observe a seasonal pattern in the coastal region of Salinópolis and that, mainly, variations in rainfall indexes influenced abiotic factors. Species of Acartia sp. and Paracalanus sp. demonstrated to be generalist and resistant, however, the low levels of dissolved oxygen can be limiting for some copepod organisms. As for environmental perception, semi structured questionnaires were applied to 500 visitors and 48 traders, with socioeconomic aspects being addressed and they behave in the face of environmental issues. The beach environment is considered democratic and in common use by the people, however, it was possible to verify that the beaches showed socioeconomic differences, where the beach of the watchtower and the old lighthouse had a monthly income between 5 to 10 minimum wages, which may be related to the fact that they are located far from the center of Salinópolis. Regarding the environmental perception of users, both tourists and traders are informed about what is solid waste and that there is an effort on the part of the government in cleaning the beaches, but this did not absent the perception of the presence of marine waste in the environment, the which indicates the need for awareness and environmental education measures. The sewage sources that would go directly to the coastal region were mapped and georeferenced, being quantified 107 effluent outlets, characterized as wolf mouths, ditches, pipes and pipes of homes, restaurants and hotels. The highest number of sewage dumps was recorded at Praia do Atalaia (n = 43) and Farol Velho (n = 38), being the ones that receive the most tourists, which emphasizes the need to implement the municipal sanitation plan of the municipality and the inspection of buildings by the sea. Thus, as a result of this research, an educational booklet about pollution and marine organisms was created, which will serve to raise environmental awareness among residents and tourists in the Salinópolis region, aiming at reducing pollutants and preserving the marine environment.PPGCA - Estudos de ecossistemas amazônicos
