Abstract:: Discard rates in marine fisheries have been estimated at more than 80% for some individual fisheries, with an average global discard rate of 8%. Discarding of catch can be problematic for three main reasons: (1) in the absence of accurate and precise discards estimates, unreliable catch data distort estimation of...

Abstract:: The very restrictive quotas of cod in the Baltic Sea are a strong force for searching alternatives. Since 1996 for instance, the cod quota for the German fishery was reduced from 22 000 t to 13 000 t in the year 2001. And further cuts took place in 2002. However,...

Creator:: Matsuda, Yoshiaki
Abstract:: Human beings are now recognizing that fish are no longer free gifts from the nature and we have to manage it wisely. The current management schemes are more or less based on the allocation of fish by individuals or communities through rules and regulations, resulting in illegal fishing, high MCS...

Abstract:: The use of Data Envelopment Analysis (DEA) has been proposed as a possible tool to enable the measurement of fishing capacity worldwide. In fisheries the DEA approach has been limited to measuring physical capacity, where capacity is defined as the maximum amount of output that can be produced per unit...

Abstract:: Recent increases in the volume of canning grade tuna caught in the Western and Central Pacific Ocean (WCPO) has led to concern about the increasing catching capacity of the fleet of purse seine vessels operating in the fishery. In this paper Data Envelopment Analysis (DEA) is used to examine the...

Abstract:: 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...

Abstract:: 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...

Abstract:: Poverty reduction and food security are key development concerns articulated through Poverty Reduction Strategy Papers (PRSPs). This paper examines the fisheries sector's participation in these strategies. Adapting Oksanen and Mersmann's (2002) methodology for assessing the status of forestry in Sub-Saharan Africa, we evaluate the fisheries sector's representation in twenty-nine African...

Abstract:: Technical efficiency (TE) measures the relationship between a vessel’s inputs to the fishing process and its outputs, with full efficiency being achieved when outputs are maximised from a given set of inputs. Inputs can be physical (e.g. the vessel, gear, engine, onboard equipment, etc.), flexible (time spent fishing, size of...
