Abstract

The most expensive Input in coastal aquaculture operations is construction and maintenance of culture ponds and farms. Experience gained on construction and maintenance of culture ponds in three localities along southeast coast of India during 1972-'85 has shown that since the earth is porous and In cohesive in this region, adequate precautions have to be taken. For Instance In order to overcome such problems as erosion of dykes due to prevailing rains, wave action of pond water at dyke bases and deposition of sand inside the ponds, suitable steps have to be devised. Another problem encountered has been poor tidal amplitudes, particularly during premonsoon months, cloture of bar mouths in the postmonsoon season and the consequent paucity of sea water supply to culture ponds- The paper gives an account of the experience gained to minimise and/ or counter these problems, in the context of the varying climatic and sail conditions in the three localities. Also, the ways and means of applying such techniques for successful management of culture ponds and farms in similar problem-prone areas are discussed.
