Evaluación de multicepas para controlar amonio (nh4) en agua de piscinas camaroneras.

Abstract

The main objective of this research paper is to evaluate the effectiveness of seven Bacillus spp. strains in the ammonia (NH₃) levels reduction in shrimp pool water and its impact on water quality. It focuses on analyzing the correct dosage of a commercial product that contains a concentration of 5 x 109 UFC/g, which are used as bioremediators to control or reduce the non-ionized ammonium form (NH₃) of the water. The parameters of the aquatic environment were measured (pH, temperature, salinity) to make sure they are in favorable conditions in the aim of the product's effectiveness. For this objective, 12 experimental units were used, the same ones that are classified into 4 treatments of different dosages and 3 replicates for each one: Control Treatment (CT; without product); Treatment one, which contains the recommended dose suggested by the manufacturer (T1; 0.12 mg); Treatment two, -50% (T2; 0.60 mg); Treatment three +50% of the principal dose (T3; 0.18 mg). This started with a load of NH₃ of 5 ppm, showing better results in T1 and T3 (0.02 ppm & 0.01 ppm). In intervals of 9 hours; these intervals were measured for 8 days of experimental work period. It was observed that it is necessary to place the correct dosage and bacteria application to achieve a reduction in the NH₃ load and prevent, with this, any risk in the shrimp pools, obtaining a good water quality using eco-friendly aquaculture commercial products.
