Observations on the seasonal variations of Physico-chemical parameters of Ayiramthengu, the mangrove ecosystem


Author(s): Divya S Rajan and Saranya P

Abstract: Mangrove ecosystems are considered to be the most productive and complex wetlands. Ayiramthengu is situated about 6 km west of Oachira town on the bank of the Kayamkulam estuary. The present study deals with the investigation of physico-chemical parameters. The study was conducted over three sites such as Cheriazheekal, Valiazheekal and Ayiramthengu during the year of 2016 for premonsoon, monsoon and post monsoon seasons. The study revealed that dissolved oxygen was found to be from 1.12 to 1.68mg/l during premonsoon and monsoon seasons in Valiazheekal region. A high value of salinity was also noticed in Ayiramthengu region. Hardness exhibited a decrease in premonsoon and monsoon season than that of post monsoon season. A remarkably higher value of turbidity ranging from 601NTU to 1044 NTU was also noticed. This indicates a sign of water quality degradation of the study area. The present investigation proves the need for conservation of this natural ecosystem in a sustainable manner.
