Environmental perception in street markets in Pará and the impacts caused by fish waste

Open markets are places of severe environmental impacts due to the large production of organic matter such as scales, fins and fins. The objective of this research was to analyze quantitatively and qualitatively the types of fish residues and the environmental perception of the fish farms regarding the environmental impacts caused by temporary storage and final disposal on the soil. The method applied was deductive, with nature applied. The primary data was obtained in three fairs in the municipality of Maraba, Pará, Brazil, from the counting of the number of boxes (n = 16) in activity, as well as that of merchants (n = 36), identification of the most sold species to characterize the fish waste. The secondary data were obtained from the document data survey with time clipping between 2010 and 2020. Statistical analysis of the data was performed using spreadsheets contained in Excel software, version 13.0. The data obtained and analyzed indicated that the temporary storage of waste is done in buckets (x = 69,5%), drums (x = 11,6%) and black plastic bags (x = 18,7%). The environmental perception of most of them (n = 69.4%) about the correct way for temporary storage of waste is low. However, there are those who know (n = 28.2%) how to reuse this waste, as occurred at the Folha 28 fair (n = 50.0%). As the environmental perception of fish traders is low, they do not know the negative impacts caused by the residues produced by them. A promote training courses for them can improve environmental perception and raise the number of environmental multipliers for environmental conservation.
