Excerpt
Excerpt: Negombo lagoon, which is one of the most productive estuaries in Sri Lanka (Pillai, 1965) is situated in the Gampaha district on the western coast, about 20 km north of Colombo, at 7?7?N and 79?50?E.It is 12 km in length and 3.75 km at its widest point. The greatest recorded water depth is 2.6 m but 10% of the lagoon has a water depth of less than 0.5 m. The lagoon covers an area ofapproximately 3,200ha andopens to the sea at its northern end. To the south, it is connected to the Muthurajawela marsh which covers an area of approximately 3,100 ha and together the lagoon andmarsh constitute aconjoined, tidally influenced coastal wetland. The main fresh water input comes from the rivers Dandugam Oya and Ja-ela but the lagoon is characterised by a brackishwater flora (seaweeds) and some mangrove forests in the northern part. These zones are very important ecologically as well as economically. Their productivity is high and they act as a silt trap and provide spawning, nursing, feeding grounds and shelter for avariety of economically important fish and shrimp species.
