Karankadu mangrove situated along the Southeast coast of India is known for its unique and extreme species diversity and richness. Ecological functions of this mangrove comprise of nutrient cycling, coastal protection, fish fauna production and carbon sequestration besides providing livelihood to nearby coastal communities. The current study having assessed seasonal fluctuations of various Physico-chemical factors viz., rainfall, pH, surface water temperature, salinity, dissolved nutrients in the water and sediments, primary productivity and plant pigments (chlorophylls a,b,c) during the study period from July 2018 to June 2019, recorded a total of 29 species of zooplankton, 26 species of phytoplankton, and 19 species of fish with observed maximum density at summer and pre-monsoon period of the year. Relationship between the biotic and abiotic components of the ecosystem from the baseline data collected, was established through the statistical analysis performed.

位于印度东南海岸的卡兰卡杜红树林以其独特而极端的物种多样性和丰富度而闻名。除了为附近的沿海社区提供生计外，这片红树林的生态功能还包括养分循环、海岸保护、鱼类生产和固碳。目前的研究评估了研究期间各种物理化学因素的季节性波动，即降雨量、pH 值、地表水温、盐度、水中和沉积物中的溶解养分、初级生产力和植物色素（叶绿素 a、b、c） 2018 年 7 月至 2019 年 6 月期间，共记录到 29 种浮游动物、26 种浮游植物和 19 种鱼类，在该年夏季和季风前期观测到密度最大。
