PRODUCTION BASED COSTING, AN ANIMATOR FOR MARKET DEVELOPMENT OF OXBOW LAKE FISHERIES (Pages : 16 - 17)

The main objective of the study was to prepare a cost function in a manner that the fishermen can manage the oxbow lakes with a community based approach in a sustainable way. The duration of the study covered a period of over 48 months, financial years 2000-01 to 2003-04. One privately managed oxbow lake (PMOL) named Morshina, one Government managed lake (GMOL) named Kathgora and the last but the least, community managed oxbow lake (CMOL) named Purakali lake were taken for this study. Annual income statements for each oxbow lake were prepared following Generally Accepted Accounting Principle (GAAP). Important costs were identified from the income statements. Contribution margins and percentage of contribution margins (%) were calculated by deducting the variable costs from selling price in terms of per unit (kg) carp yields. Contribution margins and percentage of contribution margins (%) were calculated to find out total profit of carp yields. The CMOL was taken as an experiment whereas the rest twos, PMOL & GMOL were taken as control groups where no support of Production Based Costing (PBC) was provided. Major ecological factors included primary production and other food availability in the water biomass, seasonal variations, carrying capacity, standard water area, fish growth, stocking mixes, and catch composition. Cost factors included operating costs, fixed and variable costs, contribution margins, break-even-points, daily income, market price and Benefit Cost Ratio (BCR). Social factors included income level and behavioral changes of the fishermen. By using a leassquare regression equation cost functions of yield-kg was prepared for each oxbow lake where the value of R2 was found better in CMOL in compare to the PMOL & GMOL.Download
