ABSTRACT

The present study was carried out in 37 ponds of 5 panchayaths within Athiyannoor Block in Thiruvananthapuram dist., Kerala, India. The present study helps to analyze each and every pond in the Athiyannoor block panchayath quantitatively in terms of plankton identification. Objectives of this work was water quality analysis of different ponds in Athiyannoor block, to generate a database about the ponds of the Athiyannoor Block, identification of plankton (phytoplankton, zooplankton)species in different ponds in athiyannoor block and also to identify the interrelationship between water quality and the occurrence of the plankton species in each pond. In the present study, plankton identification showed 13 species of phytoplankton and 2 species of zooplankton. Statistical analysis or correlation of abundance of phytoplanktons with parameters established a negative correlation between abundance and pH and DO but a moderate positive correlation with temperature and an independent nature of EC can be concluded from this study. Results of physicochemical parameters of various ponds showed that the water is not good for human consumption and also struggling for their existence. So there is an immediate need of restoration, improvement and proper management of these secret water bodies for the human and environment.
