Abstract Waste stabilization pond is an articial ecosystem; its performance is governed by the nature of the biological communities it supports. These are primarily used as secondary efuent treatment plants to polish the efuents. However, they are also used to treat the raw sewage and industrial efuents. In the present study, the functioning of a waste stabilization pond system from an industrial complex located in Goa was taken up. The raw waste released by the industrial complex and the nal efuent released from the stabilization ponds were analyzed for pH, dissolved oxygen (DO), biological oxygen demand,
phosphate content, chlorophyll content, and algal diversity and density. Also, the activities of the enzymes catalase and phosphatase were measured. The study was carried out for a period of 1 year and the data covering pre-monsoon, monsoon, and post-monsoon seasons are tabulated. The study revealed that DO, chlorophyll content, and algal count were maximum during pre-monsoon when compared to monsoon and post-monsoon. Similarly, maximum enzymatic activity was recorded during pre-monsoon and also maximum removal of biological oxygen demand and phosphate was recorded during this period than in monsoon and post-monsoon.

Introduction
Stabilization pond is an ideal system for treatment of industrial wastewaters containing organic substances and the treatment efciency depends on the climatic and environmental conditions of the region. Basically, stabilization pond is a complex ecosystem comprising of actions and interactions between different groups of protozoa, bacteria, algae, fungi, rotifers, and crustacean larvae which co-exist and compete with each other for food
