In this aspect there is need of water basedaquaculture system like cages, pens (inshore, offshore). The cage aquaculture sector has grown very rapidly during the past 20 years and is presently undergoing rapid changes in response to pressures from globalization and growing demand for aquatic products in both developing and developed countries. It has been predicted that fish consumption in developing countries will increase by 57 percent, from 62.7 million metric tons in 1997 to 98.6 million in 2020. Presently there are only wooden, steel, galvanised iron, and HDPE made cages in India, From past years there was an increase in novel technologies for cages in other countries but not in India, for more development there is an need of futuristic cages like closed cage from Aquafarm equipment's(As),ocean drifter IMTA, Aquapod pens, single point mooring cages etc., should be developed for future aquaculture development. 收起
