Description The impact of farming of the edible oyster Crassostrea madrasensis on the sediment characteristics in
Ashtamudi Lake was studied. The meat weight in the 25 m2 trestle (rack) farm with approximately 30,000
oysters was found to increase from 27 kg in March to 228 kg in September with a corresponding total shellon
weight of 188 kg and 1431 kg respectively. The effect of farming on the top 1-5 cm and 5-10 cm column
of the farm substrate was studied separately. Sediment in both the columns beneath the farm and the
reference site (non-farm) in the estuary was predominated by fine sand (about 70%) followed by silt, clay
and coarse sand. The average organic carbon content in the two sediment columns during the crop period
were 0.87 (1-5 cm) and 0.73 (5-10 cm). Though there were variations in the sediment texture and organic
carbon content between the farm and the reference sites the impact due to term oyster farming on these
parameters was not significant.
