Satellite data of Landsat TM, IRS 1B LISS II, IRS 1C LISS III and IRS 1D LISS III were used to monitor aquaculture
development and its spatial distribution in Cuddalore District, south-east coast of India. Analysis of satellite images using
image processing software ERDAS Imagine 9.0 and Geographic Information System (GIS) software Arc GIS 9.0 indicated
that the area under aquaculture was 6.91 ha in 1987, gradually increasing to 67.71 ha in 1994, and reaching a maximum of
380.19 ha in 1998. There was a little shrimp culture development (6.14 ha) from 1998 to 2005 because of risk of White Spot
Syndrome Virus (WSSV), epizootics and constraints related to social and environmental concerns raised against shrimp
farming. Shrimp farms initially started in the marsh areas close to creeks and then moved inland towards agricultural and
fallow lands. Farms developed in clusters along the creeks without affecting mangrove reserve forests between 1988 and
2005 and about 177.02 ha agriculture land including 234.25 ha fallow lands were converted for aquaculture farming. Shrimp
culture was abandoned in 109.47 ha and 15.13 ha of agricultural land previously converted to aquaculture farms, was
reconverted for agriculture. The present study shows that remote sensing data and GIS are useful tools in assessing and
monitoring the development of aquaculture for larger areas and suggests that national level planning using multi-spectral
satellite data can be used to assess the existing land use and the potential for sustainable use of coastal resources.
