Non-radial measure of technical efficiency of fish farms in Oyo State was examined using Data Envelopment Analysis (DEA). Use of the non-radial measures to calculate overuse of inputs by inefficient fish farmers was demonstrated and the potential for reducing inputs used by improving efficiency was evaluated. Ordinary Least Square (OLS)...
Overcapacity situations appear regularly in the activity of marine natural resource exploitation. The measure of capacity utilisation and allocative efficiency for fishing vessels is an approach that can determine the details of that overcapacity. On the one hand, DEA (Data Envelopment Analysis) methodology can be used in the case of...
Electronic monitoring (EM) systems hold promise for the future collection of fishery-dependent data, either to supplement human at-sea observers or replace them. Several pilot studies have been conducted on EM in the New England groundfish fleet, though there are still on the water operational and shore-side protocols to further test...
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...
The fish market has a long tradition in economic literature. Many authors refer to it when they want to investigate the organisation of exchanges, whether from the point of view of equilibrium or disequilibrium. This market constitutes a kind of economic paradox in the sense that, in many cases, first...
