Abstract

Aquaculture development over the past 50 years has been facilitated largely by the application of science and the introduction of new technologies. Selection of potential and suitable site is the first and foremost step for successful brackish water aquaculture. Adequate engineering and water quality parameters (such as pH, alkalinity, dissolved oxygen, total ammonia, unionized ammonia, nitrate, total nitrogen, phosphorus, BOD, COD and electrical conductivity), soil quality and topography are the most important parameters of a good site. LANDSAT ETM + 60m resolution imagery as revealed the various land forms as well as land use, land cover features in a part of srikakulam, vizianagaram, Visakhapatnam, east Godavari, west Godavari delta coastal belt.The land use/land cover as indicated that the aquaculture has phenomenally increased by 9,293.5 ha during the 9 year period at the same time , the crop land which occupied about 29,104 ha in 2001 has been reduced to 14,153.9 ha by 2010 mainly due to encroachment of aquaculture. The 5 districts of along coastal area lands which are designated as ‘aquaculture ponds’ are grouped in 2perioditic classes based on the intensity of convension.
