“…II). When the different environmental parameters of the retting zones of the present study were compared to similar studies conducted in the EdavaNadayara backwater [26], Cochin backwater [27], backwaters of Kozhikode [28] and jute retted waters of West Bengal [7], it was found that the water quality condition has further deteriorated leading to the creation of 'hot spots' of pollution in the region (Tab. III).…”

The extensive backwaters of Kerala are the sites for a flourishing cottage industry -the coir industry. This enterprise almost exclusively located along the 590 km coastal belt of Kerala, provides direct employment to over half a million people in the state and produces nearly 90% of the total coir goods in the world. The shallow bays and lagoons of the 30 backwater systems of the state are traditional areas for the retting of coconut husk for the production of the coir fibre. The paper examines the environmental status of the retting grounds in Kerala, in relation to the biotic communities. The study revealed that retting activity has caused large scale organic pollution along with the mass destruction of the flora and fauna, converting sizeable sections of the backwaters into virtual cesspools of foul smelling stagnant waters. High values of hydrogen sulphide, ammonia, BOD 5 associated with anoxic conditions and low community diversity of plankton, benthic fauna, fish, shell fish, wood boring and fouling organisms were the outstanding feature of the retting zones.

“…Retting results in release of large quantities of organic substance and chemicals including pectin, pentosan, tannins, polyphenols, sulphide, phosphate, nitrate, hydrogen sulphide, ammonia and thereby results in increased biological oxygen demand levels (Remani et al, 1989;Bijoy Nandan, 1997). This renders the backwater unsuitable for fishing and normal flora and fauna.…”

“…The retting grounds are usually located in brackish water bodies and these have a peculiar hydrobiological environment modified by the retting process. The pollution problems that have emerged consequent to prolonged periods of retting have earlier been reported by Azis and Nair 3 and Remani et al 4 .…”

Various methods are in vogue for identifying bio-indicators. But these take into consideration only the percentage abundance of the species at a definite period. A new method of analysis-Zach's program-is proposed taking into consideration all the available methods and incorporating more statistical analysis. The application has been illustrated through the studies of the coconut retting grounds adjacent to the Kayamkulam lake (Lat. 9°7'N and 9°16'N, Long. 76°20'E and 75'28'E); and advantages of the method are elaborated.
