The following experiment was carried out with the objective of evaluating the physical and chemical parameters of the water of Cumbaza river during the first phases of the reproductive process in the laboratory of the maiden (Pseudoplatystoma fasciatum), which occurred in two phases; The first one was breeding preparation, and the second phase consisted in the evaluation of the physical and chemical parameters of the water of Cumbaza River during the embryonic and larval development of the (Pseudoplatystoma fasciatum), and was carried out in the laboratory of Cacatachi farm owned by the UNSM. The regression analysis was to know the point of association between each parameter evaluated and the correlation analysis to relate each parameter evaluated with the values obtained from the larval mortality percentage. With regard to the water quality of Cumbaza River, it is indicated that they are conducive to the normal embryonic development of Pseudoplatystoma fasciatum. Which registered a period of 15 hours; in which the physical and chemical parameters recorded an average of: Temperature of 26.4 ºC, pH of 7.36, Oxygen Concentration of 7.33 mg / l, Concentration of C02 3.66 mg / l, Hardness Content (CaC03) of 45.60 mg / l with an Ammonia Concentration of 1.30 mg / l. Finally, the climatic variation with respect to the recorded temperature varied by ± 2.5 ºC from the optimum required by this species in the last larval phase, causing a high percentage of mortality in the larvae of the Pseudoplatistoma fasciatum.
