Abstract

Harvesting Giant Freshwater Prawn, Golda (Macrobrachium rosenbergii de Man 1879) in the Sundarnbans mangrove forest plays an important role in the economy of the country as well as the livelihood of local community. The study focused the economic assessment of small-scale artisanal Golda fishery. Overall the Hookline gear showed the best performance in terms of economic return. However, it was found to withstand a shock from 20% decrease in market prices or 30% fall in catch rate in terms of Return on investment, payback period and Benefit-cost ratio. Operating cost and fixed cost for Hookline fishery was the lowest and Khathijal was the highest. No significant variation (P<0.05) observed in the mean catch rate per trip boat-1 among the gears studied. Total revenue earned after completion a trip varied considerably between BDT 1,307 to 1,562. Yearly, total net revenue reached at the maximum by Hookline (BDT 38,506), followed by Chandijal (BDT 38,377) and the minimum by Khalpata (BDT 33,885). The findings of this study are supposed to be helpful for policy makers in improving the current status of Golda fishery and relevant human livelihood as well as conserving the Sundarbans Mangrove Ecosystem.
