Qualidade da água em pesque-pagues no Vale do São Patrício – GO

Abstract

Fee-fishing are environments aimed at leisure, often having the possible commercialization of species from the establishment, which implies the due importance of controlling the aquatic environment. For this purpose, water quality parameters such as transparency, temperature, hydrogen potential, cadmium, and lead of two fish farming units that function as paid fishery, located in the São Patrício Valley-GO, a region with a high concentration of water bodies, were analyzed. The hydrogen ionic potential remained within acceptable standards determined by legislation, with a variation between 7.05 and 7.39, as well as the temperature remained within the reference range, even with a constant variation between 24.5 ºC and 28 ºC, the which can affect the reproduction rate of certain species. Regarding transparency, there were values above the recommended, between 54.5 cm to 72.5 cm, as well as concentrations of cadmium and lead above acceptable for waters of this nature, where even low, they can compromise well-being species, especially when the reproductive issue of fish is discussed. It is suggested that there be research aimed at the control of paid-fishing units, since such environments, when not monitored periodically, can harm both the health of the cultivated species, as well as the final consumers, thus even generating a bioaccumulation process.
