Creator:: Andreasson, Stefan and Flaaten, Ola
Abstract:: Gear technologists have, in recent years, developed rigid sorting grids, Sort-X, in bottom trawls, to improve the size selectivity of this type of gear. Experiments with the Sort-X system in the aft sections of trawls were carried out aboard Norwegian and Russian trawlers along the coast of Northern Norway and...

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...

Abstract:: Assuming a broad set of management goals, we analyze the implementation of a marine protected area (MPA) together with open access by applying a bioeconomic model that ensures unchanged growth post-MPA. Taking into account that conservation and restoration, food security, employment and social surplus are amongst the objectives that many...

Creator:: Thi Nguyen, Kim Anh, Flaaten, Ola, Nguyen, Tuan, Thi Phan, Dung, and Thi Nguyen, Tram Anh
Abstract:: 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...

Creator:: Flaaten, Ola and Mjolhus, Einar
Abstract:: This paper demonstrates analytically how a nature reserve may protect the total population, realize maximum sustainable yield (MSY), maximum economic yield (MEY) and consumer surplus (CS) and how this depends on biological growth, migration, reserve size and economic parameters. The pre-reserve population is assumed to follow the logistic growth law...

Creator:: Thanh, Thuy Pham Thi, Flaaten, Ola, and Nguyen, Kim Anh
Abstract:: This study analyzes the determinants of the choice of remuneration systems and examines their influence on the economic performance of fisheries. The purse seine fisheries in Khanh Hoa province, Vietnam, are used as the study case, with data collected from 162 fishing households in 2005 and 2008. The principal‚ agent...
