Comparative Econometrics of Tiger Shrimp (Penaeus monodon, Fabricius) Monoculture against Polyculture at Selected Regions of Coastal Purba Medinipur of West Bengal During, 2014

S. Sahu ^[4]

Abstract: The culture potential of Tiger shrimp (Penaeus monodon, Fabricius) is well known due to its performance and economic profitability. Shrimp farming is a good opportunity to earn strong currencies. The production economics depend mainly on pond facilities, stocking density, food and fertilizer supply, water quality management, yield, technical skill and other inputs. For semi-intensive system in large areas, will require greater amount of inputs, high-level technical skills and constant supervision. The idea of polyculture is based on the principle that each species stocked has its own feeding niche that of other species. Therefore, a more complete feed schedule should be in use, which must be made of the food resources and space availability in polyculture than in monoculture. Several benefits have been achieved in shrimp polyculture systems when using fish, bivalves and seaweed as subordinate species, viz. no need to maintain stocking density, availability of natural feeds and manure and low investment than monoculture. Tiger shrimp monoculture has several disadvantages with respect to benefits, viz. high input cost, maintain the stocking density with respect to pond size, perform soil and water quality parameters regularly and no partial income is earn with respect to polyculture. - that is why the common farmers in the study area show affinity to polyculture. By means of governments intervention and support this will in turn accelerate the employment generation.
