Abstract

Kolpadam kadavu is a part of Ashtamudi Lake and it is the region having significant retting as it is used as a retting ground for many years. Retting is a traditional process of soaking green coconut husk in water for making coir fibre. The waste disposal from the coconut husk retting causes increases of toxic ingredients such as acids, alkalis, suspended solids, polyphenols, pectin, tannin etc. make threatening effect on aquatic organisms. The present investigation was carried out to analyse the various hydrographical parameters and its toxic effect on fish population in Kolpadam kadavu. The physico-chemical parameters were analysed on monthly basis from June 2018 to November 2018. The water samples were used for estimation of parameters such as temperature, pH, DO, CO2, total hardness, nitrate, total phenol, iron etc. Etroplus suratensis and Arius subrostratus collected from Kolpadam kadavu was subjected to haematological analysis such as Hb, RBC, WBC, ESR, PCV, MCV, MCH and MCHC.
