The paper introduces and analyses first the evolution, actuality and current problems of the summer closed fishing season system of China. The summer closed fishing season system is formally actualized in 1995. Till 2006, all waters of China is managed by the very system. During summer closed fishing season of...
According to the UN's Food and agicultural organisation (FAO, managing fishing capacity is a core elemnt to aceive sustainable fisheries. Here, FAO highlight the long term need to avoid unprofitable overcapacity; an adaptation which increase the pressure on fish resources, fisheres are marginalized economically, allocation conflicts among fishermen and high...
This paper presents the findings of risk identification and risk perception research conducted in relation to the fisheries systems of four distinct and diverse European countries: Faroes, Iceland, Greece and the UK. Risk research traditionally attempts to quantify the potential threat or consequences from a range of risk events or...
The Lower Mekong Basin (LMB) is shared by Thailand, Lao PDR, Cambodia and Vietnam and provides a range of natural resources and services which are important to the national economies (e.g. water for hydro-electric power) and also to the livelihoods of the people (e.g. fishing and farming opportunities) in the...
Fisheries management as we know it today is in a perpetual state of crisis because it is fatally flawed. Fisheries management will increasingly fail to prevent species decline, and even exacerbate those declines, unless it adopts new institutional priorities and methodologies based not on the prevalent “Industrial Model,” which is...
To achieve sustainable fisheries, ecosystem-based fisheries management
yields increasing attention. However, so far mainly single-species models
are used to develop management advice, not accounting for species
interaction. In particular many traditional fisheries economic models have
been criticized by biologists, especially if results were gained by rather
simple biomass models. Therefore,...
In this paper, we analyze the efficiency of the existing management regime
of the Bay of Biscay anchovy fishery, which has been closed since 2005
due to stock collapse. We also study Pareto improving strategies to
improve management of the fishery once the moratorium is lifted, expected
for spring 2011....
Yearly revisions of Total Allowable Catch under EU policies for the management of North Sea fisheries come at
high management costs and capital adjustment costs. It is unclear whether current EU fisheries policy strikes the
right balance between the need to regularly adjust fish quota to new information on one...
We define the notion of sustainable yields for ecosystem, with particular
emphasis on long-run consistency between ecological and economic conflicting
objectives. We provide a way to compute sustainable yields by means of
a viability analysis of generic ecosystem models with harvesting. We apply
our approach to a Lotka–Volterra model of...
