MARTINEZ SANCHEZ, Martha Elena et al. Use of Saccharomyces cerevisiae to control the quantity and quality of water in white shrimp culture. Rev. Mex. Cienc. Agríc [online]. 2018, vol.9, n.7, pp.1339-1349.  Epub Sep 30, 2020. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v9i7.1669.

We evaluated the effect of BlueEnergyRent product based on yeast Saccharomyces cerevisiae and molasses, on the cultivation of white shrimp Litopenaeus vannamei, determining the impact on water quality parameters, and productive. The experiment was carried out at the Acuilan aquaculture farm, located in La Antigua, Veracruz, Mexico, in 2015. In the shrimp culture, 1.5 g/m3/day of the active molasses-yeast mixture was added as the first treatment and a daily dose adjusted based on the total ammoniacal nitrogen in the second treatment. Both were compared against a treatment with constant water flow. It was observed that BlueEnergyRent did not negatively affect the quality of the water, the productive parameters presented better levels with the treatment based on the total ammoniacal nitrogen, and it was possible to reduce the consumption of water for each kg of shrimp produced to 3.9 m3 kg-1. Healthy organisms with normal growth were harvested with a feed conversion ratio of 1.19. By using BlueEnergyRent the use of water is improved without affecting crop performance.
