Mud crab (Scylla serrata Forsskal 1775) value chain analysis in the Khulna region of Bangladesh

Abstract

A value chain analysis is a detailed description of all the activities and services needed to turn a raw product into a marketable good for delivery to final consumers. The mud crab business is considered by most marketing operators to be a profitable and viable business due to the high demand in the international market. Despite the importance of mud crab fishery, there is no structured marketing facilities in Bangladesh. This research aim to analyze the socioeconomic condition of actors, the profitability of farming, mapping the institutional and non-institutional barriers, and provide a better understanding of the possibility of technological interventions in the value chain. Qualitative and quantitative data were collected through participatory rural appraisal tools that include 200 individual interviews, 16 focus group discussions, and 24 key informant interviews conducted in south-west Bangladesh from July to December of 2019. The mud crab value chain analysis revealed that the chain started with crab collection (cultivated and wild harvest), before sale to local vendors, and ended with exporters through several intermediaries. Results noted that most (±95%) exportable crab came from natural sources, with rest (±5%) from aquaculture sector. The average price (USD/kg) ranged from $10.59−14.12 and $12.94−19.42 for male crabs (grade: XXL), followed by $10.00−11.77 and $11.77−17.06 for female (grade: FF1) in domestic and international markets, respectively. Despite the high profitability of these sectors, the livelihood of these stakeholders has remained relatively hard. Multi-pronged approaches, like a nursery or increasing farming and backyard seed production, and possible value addition at the farm level may help farmers.
