Creator:: Flaaten, Ola
Abstract:: The aim of this paper is to assist teaching undergraduate students how to analyse the issue of fish stock investment. The mathematical prerequisites are a basic knowledge of calculus. Both discrete and continuos time frameworks are used. To fish down or to build up a fish stock takes time, and...

Creator:: Sharp, Basil and Jeffs, Andrew
Abstract:: The scope for fishing firms operating in an output controlled fishery, with tradable rights, and facing world prices, to augment profit is limited inter alia to a search for alternative input configurations that lower harvesting costs. This paper provides evidence of technical change in the New Zealand rock lobster fishery....

Creator:: Castilla Espino, David, García Ordaz, Félix, and Sharp, Basil M. H.
Abstract:: 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....

Creator:: Accadia, Paolo and Spagnolo, Massimo
Abstract:: This paper presents a new bio-economic simulation model for the Italian fisheries developed as a part of a project financed by The General Directorate for Fisheries and Aquaculture (under the Italian Ministry of Forestry and Agriculture Policies). The main objective of the model is to measure the effects of different...

Abstract:: 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...

Creator:: del Hoyo, Garcia J.J., Castilla-Espino, M.D., Gonzalez-Galan, R., Jimenez-Toribio, R., and Cortes-Rodriguez, C.
Abstract:: In this paper we analyse different econometric procedures of technical efficiency to estimate fishing capacity. These procedures are then applied to the purse seine fishery located in the Gulf of Cádiz. The target species of this fishery has changed quite a lot over the past few years. It used to...

Creator:: Otoo, Justin, Onumah, Edward Ebo, and Osei-Asare, Yaw
Abstract:: Ghana's coast is identified with artisanal fishers who use wooden carved canoes and traditional fishing gears. However, little study has been conducted to assess the performance of this industry in terms of its efficiency. This study aims to analyse the technical efficiency and its determinants of the artisanal fishers in...

Creator:: Ojo, S. O., Faphunda, O. O., and Fagbenro, O. A.
Abstract:: Nigerian aquaculture industry is fairly well developed and ranks second in Africa. It has low production levels compared with the country's aquaculture production potentials. Aquaculture production in 2001 was 47,000 tonnes contributing 9.92% of total fisheries production. If aquaculture production is to play its expected role in economic development of...

Creator:: Tingley, Diana and Pascoe, Sean
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...

Creator:: Pascoe, Sean, Coglan, Louisa, and Cattermoul, Ben
Abstract:: Differences in technical efficiency of fishing vessels are often attributed to skipper skill and differences in technology. While the later can be defined in terms of the technology employed, the former is more difficult to quantify. In this paper, the contribution of technology and skipper characteristics (e.g. level of education,...
