ANALYSIS OF FISH FARMING, NUTRIENT INPUT AND PRODUCTION OF THE OCOY RIVER WATERSHED

Abstract

Geotechnologies have become an essential tool for determining the sustainable development potential of aquaculture. The objective of this work was to map the physical and natural resources of the Ocoy River watershed. The mapping of the excavated ponds was carried out to estimate the discharge of Nitrogen and Phosphorus due to the fish farming activities of the microbasin. The methodology adopted was the qualitative and quantitative exploratory research for fish production and the use of open access geotechnology tools, such as QGIS and google Earth for mapping physical and natural resources. The methodology employed by Coldebella et al (2020) was used to estimate the nutrient input of fish farming in the watershed. characteristics are considered suitable for the development and expansion of fish farming in excavated ponds. The characteristics of the watershed are suitable for the expansion of aquaculture activity in the region, as it has a predominance of relief in hypsometric ranges of 200 to 300 meters, with gently undulating relief; the soil type Red Nitosol and morphometry that indicates that the watershed has a low risk of flooding and an elongated shape. Estimated ratios of Nitrogen and Phosphorus are low.
