Potential of cage culture as a key technological intervention in open water bodies to enhance fish productivity is well known and which is also recognised by government for achieving blue revolution goals. The present study is an attempt to investigate the economics of GI pipe cage manufacturing in Jharkhand. The result revealed that GI pipe cage manufacturing was a capital oriented enterprise requiring high initial investment for the establishing cage manufacturing unit. The costs and return analysis showed total cost to be Rs.9.05 crores generating gross revenue of Rs.12 crores per annum. It was observed that variable cost contribute about 96.64 percent while fixed cost contribute only 3.36 percent of the total cost respectively. The procurement of raw materials was found to contribute the lion share in cost of production which was 90.64 percent (Rs.8.17 crores) of the total cost. Hence from the study it can be concluded that GI pipe cage manufacturing is capital intensive enterprise . However cage manufacturing was economically viable business indicated from BC ratio of 1.33. To further improve the economic performance of cage manufacturing there was need to minimise cost of production by finding locally available cheap raw material alternatives like Bamboo and increasing the demand for cage culture which was the major constraint encountered in cage manufacturing in Jharkhand .
