This paper discusses the use of resource assessment surveys as the basis for effective fisheries management drawing on the resource assessment survey of the Arabian Sea coast of Oman. This survey, completed in 2009, has been undertaken in the context of the primary aim of the Oman Ministry of Fisheries...
Stock assessment techniques currently used in the United States are extremely costly to implement, involve significant data requirements, and are inaccessible to all but a few stock assessment scientists. A systematic decrease in fishery yields and the designation of several species as overfished on the west coast of the United...
The paper will report on the development of a new set of wealth-based
Fishery Performance Indicators (FPI) for evaluating and comparing the
worlds fisheries management systems. A wealth-based fishery management
system is one that is ecologically sustainable, socially acceptable, and
generates sustainable resource rents or profits. The Fishery Performance
Indicators...
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...
A Seafood Environmental Management Systems manual (SEMS) has been developed by Bord Iascaigh
Mhara (The Irish Sea Fisheries Board) in conjunction with the Irish fishing industry to encourage
fishermen to adopt an environmentally conscious, responsible and compliant approach to their business.
The documented risk-based SEMS approach developed is essentially a...
In the mid-90s the Commonwealth Scientific and Research Organisation
(CSIRO) funded a social science (economics) research trip to the Gulf of
Carpentaria. The objective of the trip was to observe and model
commercial fishing patterns in the NPF, and develop an all encompassing
model for describing fleet dynamics in the...
It has been established that the path of a fishery over time, i.e. stocks, fleets, effort and profits, depends inter alia on the enforcement of the fisheries management rules in place. It has further been established that optimal enforcement of fisheries management rules depends inter alia on the shadow value...
The northwest coast of Mexico is accountable for almost 70 % of the
country´s fishery production. This region, which includes the Gulf of
California and the Pacific coast of the Baja California Peninsula, is also
extremely important in terms of biodiversity and the presence of endemic
species. Consequently, eleven marine...
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,...
The 2002 World Summit on Sustainable Development saw governments
around the world undertake to maintain or restore stocks to levels that can
produce the maximum sustainable yield with the aim of achieving these
goals for depleted stocks on an urgent basis and where possible not later
than 2015. However, progress...
The last fifteen years have seen increased reference to and adoption of comanagement
in fisheries in Southern Africa, usually as a conditionality for
(national or international) development aid in the sector. Co-management is
supposed to improve the proficiency and efficiency of fisheries
management through decentralization and democratization of decisionmaking,
which...
Fisheries exploitation at a large scale in the South Atlantic is recent.
Fisheries have experienced an extraordinary growth in the last 15 years. In
Argentina the growth of fisheries exploitation took place at unprecedented
rates, and this has been one of Argentina's most dynamic economic sectors
in recent times. It...
In most of the coastal countries, the fisheries enable to satisfy multiple socio-economic needs such as food safety, public receipts, employment and so on. It is especially true in many coastal developing countries where fisheries constitute a considerable source of food and incomes. However, the strong pressure on the fisheries...
This paper presents the findings of an 18 months global review of organisations providing sustainable fisheries information to consumers and other channel intermediaries completed in December 2009*. The project was managed by a consortium of nine organisations involved with seafood, the Fish Sustainability Information Group (FSIG), from around the world...
Over the past century, the tuna canning industry has been dominated by a few big companies, some of
them having changed of ownership or merged: these oligopolistic firms are the “big three” in the USA,
Van Camp, Star Kist, and Bumble Bee, the French Saupiquet, the Italian Trinity Alimentari and...
The Philippines, located within the Coral Triangle which represents the epicenter of marine life abundance and diversity, is the source of groupers traded in Hongkong, China, Singapore and other countries. Grouper production in the country (19.7 th mt), gross value (USD 5.8 mil) and trade value (USD 14.4 mil) is...
Fisheries economics theory suggests that weak fishery management
institutions, such as an open access regime, provide the motivation for
fishers to act as if they have infinite discount rates. This theory has serious
implications for the management of small-scale reef based fisheries in
developing countries, many of which are open...
Fishing for the life reef fish has been an important source of economy both at macro level and micro level. At Macro level, life reef fish for food (LRFF) plays a greater role in increasing export revenue since most of the fish are sold in overseas markets such Hong Kong...
Kattudel or stake net fishery is an ancient (from early 1950s) lagoon fishing technique in many regions of Sri Lanka. It drags special attention due to the absence of open access nature. The fishery is regulated by kattudel association stemming from the Catholic Church. In fact, the fishery has its...
