Engineering consideration for cage aquaculture

Abstract

Cage aquaculture has grown very rapidly during the past 20 years and is presently undergoing rapid changes in response to pressure from globalization and growing global demand for aquatic products. A cage represents a delineated volume in the body of water where the aquatic organism can be farmed. Designing and engineering are major components for cage aquaculture and it is essential to select ideal construction material, proper designing, suitable mooring and good management practices in bringing out commercial cage aquaculture which is quite simple and economically feasible. A range of cage systems is now potentially available for off-shore mariculture in world, though not all of these may prove to be effective in the intended environmental conditions and production regimes. The cost of installation and operation is also very critical. This paper provides an overview of the engineering components, and gives a brief description about various engineering
