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...
To ensure the long-term conservation and sustainable use of straddling fish stocks, the 1995 United
Nations Fish Stock Agreement calls for the establishment of regional fisheries management organizations
to manage such stocks. This paper studies the potential for cooperation in straddling stock fisheries when
the cooperative coalition of countries acts...
Vietnam’s marine fisheries are in need of knowledge-based management. This necessitates the establishment of
reliable indicators, which in turn entails a good data collecting and processing system. To bridge the gap between
specific requirements for fisheries policy development and the limited resources available, we have conducted a
study on costs...
Vietnam’s policy is to shift the fishing pressure from onshore to offshore water since the coastal resource has been overexploited, and a programme for investing in offshore vessels has thus been implemented since 1997. The question raised is whether the offshore fishing fleet is profitable and efficient or not? This...
Economic indicators are needed for future knowledge-based fisheries management in Vietnam. This entails a good data collecting and processing system. This paper contributes to this requirement for the tuna-mackerel gillnet fishery, near-shore and offshore, in Nha Trang, South-Central Vietnam. For 2005 and 2006 fifty vessels were surveyed for technical characteristics,...
This is a study on economic implications of the 3 year harvest control rule (HCR) for the Northeast Arctic
cod stock, decided in November 2002 by the Joint Norwegian-Russian Fisheries Commission. Outcomes
of this rule are compared to those of five other rules, including the previous one based on a...
Fisheries biologists and other marine scientists working closely with the regional fisheries organisations (RFOs), such as the International Council for Exploration of the Sea (ICES) have developed and applied different concepts and methods, including reference points, for assessment and management of fish stocks. However, management recommendations are usually not based...
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...
Are Marine Protected Areas positive for adjacent fisheries? This is a study of the technical efficiency of small-scale trawlers in Nha Trang, Vietnam following establishment of Nha Trang Bay Marine Protected Area (NTB-MPA) that imposed a trawl ban to protect marine biodiversity and regenerate fish stocks. Data were collected through...
