Site selection criteria for marine finfish netcage culture in Asia
Netcage culture is a popular method of rearing finfish along the coastline. This new technology utilizes little physical facilities, less space, low initial investment and is moderately inexpensive to operate. Another advantage is the easy and fast harvesting of live fish which fetch higher price in the market. There are two general types of cages, floating and stationary. A floating cage is made up of a floating unit from which a single or a series of netcages are suspended. Some of them are mobile and can be easily towed away. A stationary cage, on the other hand, is tied to fixed poles at their corners. In Asia, finfish like grouper (Epinephelus tauvina), seabass (Lates calcarifer), snapper (Lutjanus spp.) and siganid (Siganus spp.) are cultured in commercial scales in tropical countries such as Singapore, Thailand, Malaysia, Philippines, Indonesia and Hong Kong. While other finfish like red sea-bream (Pagrosomus major), black sea-bream (Sparus microcephalus), yellow tail (Seriola quinqueradiata), flatfish (Paralichthys olivaceus) etc., are cultured in temperate waters, such as in China, DPRKorea, ROKorea and Japan. Proper site selection for marine netcage culture is of paramount importance as it may considerably affect construction costs, operating costs, growth and survival rate of the fish, and the period of usefulness of the cages. Although floating cages can be usually towed away, sometimes it is not economical to do so
