LIMNOLOGICAL STUDIES AND ANALYSIS OF WET SOIL LAND AND POND WATER AROUND MUKKUDI VILLAGE OF SIVAGANGAI DISTRICT, TAMILNADU, INDIA

Abstract

The physico-chemical state of water plays a vital role in the ecosystem of wetlands. The different physicochemical parameters of mukkudi village water were studied from January 2021 to December 2021 to discover its impact on the planktonic population, fish farming and agriculture. The authors recorded water temperature ranges of 29 to 37°C, transparency ranges of 28.4 to 37.8 cm, dissolved oxygen ranges of 7.9 to 9.1 ppm, free carbon 12.8 to 14.7 ppm, pH ranges of 6.7-7.5, total alkalinity ranges of 178 to 205 ppm, total solids are 97 to 109 ppm, nitrates between 1.01 and 1.12 ppm and phosphates between 0.88 and 0.99 ppm. More than 20 species of phytoplankton and zooplankton have also been identified. A bimodal pattern of seasonal variation in plankton was observed with a primary peak between June and August and a secondary peak as on December 2021.
