Oyster farm management advisory: spacing between farms

Abstract

The edible oyster Crassostrea madrasensis commonly known as the backwater oyster is farmed in the estuarine regions of Kerala by setting up wooden rack farms from which rens are suspended. Proximity to the homesteads is one of the reasons for this technology to become popular among women self help groups. The farming season is from November/December to June, but may extend to July also depending on the onset of monsoon. At present, the farm structures are near to the shore line in a linear manner, providing space for navigation in the inner part of the estuarine channels. Initially when commercial farming started in Sattar Island in the year 2002, there were only few farms, hence, spacing of farms was not a problem.
