Abstract

An integrated system of marine polyculture of shrimp with Gracilaria, pearl oyster and sea cucumber is proposed here through this project concept for adoption to help revive the shrimp farms suffering from the problems of white spot disease and intense slushformation in the pond bottoms on account of intensive monoculture practices. The project proposes introduction officiating, mobile, motorized sea farm platforms made of four artisanal boats each, which will function as a seafarming-cum-fish aggregating-cum-fishing device. Also included in the project is the construction of artificial reef complexes made of triangular concrete modules in order to create habitats for the colonisation of commercialfish stocks. The seafarming cum- seaflshing platforms can function dependent on or independently of the artificial reef complexes. Conversion of the existing surplus boats in the Indian fishing fleets into such platforms seems to be the only means of rehabilitating the idling, unproductive boats and the fishermen. A multipurpose marine hatchery complex is included in the project to produce seeds of all the target candidate species for sea ranching in the artificial reef sites, for meeting the seed requirements of the project's onshore polyculture farm and of the seaf arm, and supply for onfarm trials in the adopted farms. The project facilities and infrastructure shouldfocus mainly on the popularisation of ecofriendly marine polyculture practices, which alone could make coastal aquculture and seafarming viable in the long run.
