The objective was to evaluate the pollutant load of BOD and COD of residual effluent discharges from the Lucre-Yanamanchi small population fish-farms to the Lucre river. 16 samples of 8 discharges were taken, considering the season. Physicochemical field parameters were determined with multiparameter water (M&A instruments AZ86031): pH, conductivity and temperature. An LG-4 portable current meter (flowmeter) was used to determine the flow (m3/h). BOD and COD samples were taken with a wide mouth jar and a narrow mouth jar correspondingly; they were preserved and taken to laboratory for analysis using standardized methods. The laboratory results made it possible to calculate the pollutant load corresponding to the amount of pollutant that is discharged per unit of time, expressed in kg/day. The physicochemical characteristics of the discharges turned out to be slightly acid, without the presence of salts. The highest value of COD is the Monitoring Point (PM) 006 with a concentration of 537.3 mg/L; the lowest is PM-004 with 200mg/L. While for the BOD the highest value is in PM-008 with 230mg/L and the lowest, PM-008 with 42mg/L. The pollutant load results for BOD and COD are high. For BOD5, according to the goals of the 2016 - 2021 Five-Year Period for aquaculture activities; all monitoring points, exception of PM-001 and PM-002 in the rainy season, exceed the established limit (50kg/day); reaching its highest value in PM-004 with 731.71 kg/day.
