Towards Economic Sustainability or Unsustainability: The Case of Artisanal Fisheries in the Bay of Bengal
Globally, excess capacity and overexploitation of fisheries have become growing concerns because of the associated fishing, social, political, and economic consequences. This study estimates the degrees of capacity utilization and technical efficiency, and the factors affecting the capacity utilization of the multispecies gill-net vessels operating in the Bay of Bengal. It is based on data collected from two marine fishing areas in Bangladesh and uses data envelopment analysis and Tobit regression. Our results indicate low degrees of capacity utilization and high degrees of technical inefficiency. However, by holding production at an efficient level, unbiased capacity utilization is close to full capacity. A high degree of excess capacity exists, and more than one-third of vessels could be decommissioned. Furthermore, vessel capacity, number of trips, and trip duration affect capacity utilization. An implication of our results is that efficient management of vessel capacity might be helpful in controlling harvest and reducing overexploitation.
期刊介绍:
Marine Resource Economics (MRE) publishes creative and scholarly economic analyses of a range of issues related to natural resource use in the global marine environment. The scope of the journal includes conceptual and empirical investigations aimed at addressing real-world oceans and coastal policy problems. Examples include studies of fisheries, aquaculture, seafood marketing and trade, marine biodiversity, marine and coastal recreation, marine pollution, offshore oil and gas, seabed mining, renewable ocean energy sources, marine transportation, coastal land use and climate adaptation, and management of estuaries and watersheds.
