| dc.description | ABSTRACT
The investigation has been made to examine the hydrological condition of the studied area (some physicochemical parameter of water, zooplankton community and its diversity).
During the study it was observed that the trend of variation of water temperature was from 15.9ºc to17.5ºc. pH was found to alkaline ranging from 8.5 to 9.1. During the study there was a fluctuation in O2 level from 3.2 mg/lit. to 5.2 mg/lit. Free CO2 was found to be higher throughout the study with a variation from 14 to 18 mg/lit.
In the study of Zooplankton, Cladocera and Rotifera were chiefly present comprising mostly of Daphnia sp, Rotaria sp., Brachionus sp. and Cyclops spp. Besides theae groups of species Copepoda was also present.
A total of 10 genera including one larval form were found during study. Among 10 genera only 5 were dominant ( Daphnia sp., Rotaria sp., Brachionus sp., Mesocyclops sp. and nauplius larvae), within these dominant species the most dominant were Daphnia sp., Rotaria sp. and Brachionus sp. which occur more than three times during study.
While the community study was concerned it was found that the species richness ranged from 0.734 to 1.17, Evenness from 0.911 to 0.975 and Shannon-Wiener index value was varied between 1.85 and 2.43. The mean values of them were 0.924, 0.939 and 2.25 respectively. | en-US |

La investigación se ha realizado para examinar la condición hidrológica del área de estudio (algún parámetro fisicoquímico del agua, comunidad de zooplancton y su diversidad).Durante el estudio se observó que la tendencia de variación de la temperatura del agua fue de 15.9ºc a 17.5ºc. Se encontró que el pH era alcalino entre 8.5 y 9.1. Durante el estudio hubo una fluctuación en el nivel de O2 de 3.2 mg / litro. a 5.2 mg / litro. Se encontró que el CO2 libre era más alto a lo largo del estudio con una variación de 14 a 18 mg / litro.En el estudio de zooplancton, Cladocera y Rotifera estuvieron presentes principalmente, que comprenden principalmente Daphnia sp., Rotaria sp., Brachionus sp. y Cyclops spp. Además de theae también estuvieron presentes grupos de especies Copepoda.Durante el estudio se encontraron un total de 10 géneros, incluida una forma larvaria. Entre los 10 géneros solo 5 fueron dominantes (Daphnia sp., Rotaria sp., Brachionus sp., Mesocyclops sp. Y nauplius larvae), dentro de estas especies dominantes las más dominantes fueron Daphnia sp., Rotaria sp. y Brachionus sp. que ocurren más de tres veces durante el estudio.Si bien el estudio de la comunidad estaba preocupado, se encontró que la riqueza de especies varió de 0.734 a 1.17, la uniformidad de 0.911 a 0.975 y el valor del índice de Shannon-Wiener varió entre 1.85 y 2.43. Los valores medios de los mismos fueron 0.924, 0.939 y 2.25 respectivamente. | es-ES |
