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....
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...
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...
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...
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...
Fisheries worldwide continue to suffer from the negative consequences of open access. In 1986, New Zealand responded by establishing an individual transferable quota (ITQ) system that by 1998 included 33 species and more than 150 markets for fishing quotas. We assess these markets in terms of trends in market activity,...
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...
The study examined the marketing of frozen fish in southwestern Nigeria. It determined the profitability of fish marketing and investigates the market structure for fish in the study area. A multistage sampling technique was used to select 150 frozen fish marketers in the study area. Gross margin analysis and Gini-coefficient...
Economic performance indicators are needed in order to improve fisheries policy in Vietnam. The
research project “Revenues and Costs of Fishing Vessels in the Nha Trang Area” has been established to
meet these needs. A questionnaire about technical characteristics and economic data of vessel and gear
in use in the...
