| Summary: | In this work the objective was to evaluate four treatments using dung of different kinds from experimental cultures, estimating their efficiency in relation to pisciculture production and the characteristics of each pond. The work was carried out in the Laboratorio de Hidrobiología of the Universidad Autónoma del Estado de Morelos (UAEM) in Cuernavaca, Morelos, Mexico, in fiberglass ponds with albinotic Oreochromis niloticus. Analysis was made of plankton, as well as bacteriological, dietectic and piscicultural growth and the physical chemistry of water. Fresh chicken excrement showed variations in the amount of nutriments. Abundance of phytoplankton was from 17,008 to 70,080 org/ml. The most abundant was Closterium sp. In zooplankton, total abundance was from 302 to 1,706 org/ml. The dominant zooplankton was Moina sp. with a yield from 22 to 117 g/m2/ 6 months. Considering these findings, it was observed that the digested chicken dung was the most efficient of the four. Pathogenic enterobacteria were always present. |
