Cold deep sea water technology utilizes the cold deep and warm surface sea water to rear indigenous and culture extraneous species of marine life and plant. The cold deep sea water can be found at one kilometer below the warm surface sea water. They can be mixed to produce a biological clean and nutrient-rich effluent with a wide range of temperature. It has a variety of aquaculture and fishery uses. Scientists at the Natural Energy Laboratory of Hawaii, Hawaii Island and St. Croix Mariculture Facility, US Virgin Island used the cold deep sea water to successfully culture a number of species of crustacean, finfish, seaweed and shellfish. All of them have ready market. Examples are trout, salmon, lobsters, oysters, and nori, to name a few. All ASEAN countries except Singapore have access to huge cold water resources. They are located underneath the sea surface within their 200-nautical mile exclusive economic zones. Indonesia, Malaysia, the Philippines, and Thailand have aquaculture and fishery industries. Their operations are hindered by the depletion of Coastal marine life resources, high costs of fish feeds, and sea water-related problems. The technology can be used not only to alleviate the problems but also to increase the yields of the industries. The paper discusses the cold deep sea water technology and its uses to improve the economies of the ASEAN countries. It deals with rearing indigenous and culturing extraneous species of marine life and plant. It identifies extrinsic aquaculture and fishery industries using the technology that can be introduced in the ASEAN region.
