A wide range of fisheries are managed using vessel catch limits combined with different kinds of effort restrictions. This management framework is expected to have desirable consequences for the bioeconomic sustainability of fisheries. When appropriately implemented this approach produces outcomes that are similar to those associated with individual fishing quotas....
In this paper, the estimate of the productive efficiency for some Italian fleet segments is proposed. The estimate is based on a Stochastic Frontier Production (SFP) function and a Data Envelopment Analysis frontier (DEA) using micro data of fishing vessels. The essential random nature of the fishing processes under consideration...
This paper contributes to the literature on economic efficiency, technical change, bioeconomic modeling, and renewable resource economics in general by introducing output-oriented Debreu-Farrell technical inefficiency and technical progress into normative static and dynamic bioeconomic models of a fishery and examines the economic and policy ramifications for the open-access Nash and...
This study examines income generation potential and resource- use efficiency of aquaculture farms in Nigeria. A total of 120 aquaculture farms were sampled. Using gross margin (GM) analysis, the result shows that, all the sampled farms were able to cover their total operating expenses with an average GM > 200,000...
Outputs and inputs during 1994-2006 in the USA Northeast Multispecies (groundfish) fishery—including days fished for a group of 47 otter trawl vessels fishing out of New Bedford, Massachusetts, USA—were analyzed to test the hypothesis that restricting the annual days-at-sea (DAS) of individual fishing vessels increased Technical Efficiency (TE). The results...
Milkfish has been farmed in Taiwan for over 300 years. Faced with a limited land resource, the industry is looking at the problem of how to maintain a sustainable and efficient production. This study specified a stochastic production frontier function to estimate potential milkfish farm output and efficiency by using...
