Data derived from food balance sheets (FBSs) and national household food consumption surveys (NHFCSs) show that fish consumption has been increased in the last 20 years in Iran. The gap between supply and...
It is fitting for the theme of IIFET 2000 “Microbehavior and Macroresults” that some of the smallest life forms on planet Earth (caliciviruses measuring 36 nanometers in diameter), which replicate only inside the living cells of their hosts, be examined. From their beginnings in this microscopic ecologic niche where they...
Excess capacity results because fishermen do not have an incentive to conserve fish in-the-sea causing them to over-invest in the capital used to harvest fish as well as other production or factor inputs.1 Excess capacity like overcapitalization and overfishing is a symptom of our regulated, open access fishery management system....
The EU framework for the collection and management of fisheries data (EU Reg. 1004/2017) requires estimates of four variables related to capital value and capital cost of fishing fleets, i.e. Consumption of fixed capital, Value of physical capital, Value of quota and other fishing rights, Investments in tangible assets. The...
The role of aquaculture industry is becoming more prominent in order to supplement marine capture in meeting the food need of the growing population. In an attempt to minimize depletion of marine fisheries only traditional vessels are allowed to fish along the coastal area while bigger vessels are regulated to...
The research for this paper was triggered by a stunning judgement of the Icelandic Supreme Court in December 1998, which declared as unconstitutional existing fisheries laws on individual transferable quotas (ITQs), because they privileged those who derived their fishing rights from ownership of vessels during a specific period over which...
Fisheries resources in Oregon have been the focus of a public policy and management controversy for the last several years. As changes in fisheries resources management and policy decisions continue to be occur, the two communities that are directly involved - the fishery management community and the fishing family business...
The diplomatic corps of Iceland has used much of its time during the third quarter of the 20. century to convince other nations that Icelanders should control and utilise the resources of the waters within 12, then 50 and finally 200 nautical miles around the island. Icelandic politicians have used...
The small-scale coastal fisheries of Virginia account for a significant portion of the state’s total annual landings and employ thousands of individuals. Despite the value of these fisheries, the number of commercial licenses sold has declined more than 15% since 1994. Declines are attributed to various factors, but indicate potential...
Due to the immanent common property problem of water, non-point-pollution is the common feature of many inland waters and the eutrophic levels are alarmingly high. drinking water and other services are negatively affected by high eutrophic levels fisheries.

Many records provide the bases for a clearer understanding of the roles of climate regime shifts and short-term perturbations in ecosystem dynamics, hence fisheries responses. Too few have taken the long view of the role of humans in this "Grand Fugue". As one of many predators, it is imperative that...
Pacific Salmon are anadromous fish that cross state and international boundaries in their oceanic migrations. Fish spawned in the rivers of one jurisdiction are vulnerable to harvest in other jurisdictions. The rocky history of attempts by the United States and Canada to cooperatively manage their respective salmon harvests suggests that...
Low-value fish/ fishery by-products are potential economic resources for developing animal feeds. Accordingly, fish protein hydrolyzed technology is an excellent way to provide protein sources for animal nutrition. However, the nutritional quality and applying this new feed supplement are severely related to the production stages and next characteristics of agricultural...
Collaborative research initiatives between New Zealand’s fisheries management agencies and commercial fisher organisations are commonplace. This can be attributed to a combination of fisheries management institutions and processes that on the one hand create incentives for commercial fishers to take increasing responsibility for fisheries research and on the other hand...
The transition process from the Soviet economical system to the market economy in fisheries has received
relatively little attention from fisheries researchers. This study analyze how overall changes in political and economical life
of Estonia during the last decade have affected the complex system of the environmental, economic, social and...
It is often said that the reason why Community-Based Fishery Management System (CBFM) in Japan has been well practiced is due to a historical development of a fishing right system, which emerged during her feudal era. This is not always correct. Until August 1945, when Japan was defeated in the...
In “Landing fees vs. harvest quotas with
uncertain fish stocks”, Martin Weitzman maintains that
the conventional view among both fisheries economists
and fisheries managers is that “prices” are inferior to
“quantities” as instruments for regulating the fishing
industry. Weitzman takes the opposite position,
appealing to two well-established ideas in economics:...
Weitzman's paper is useful because it provides the fisheries economics profession with a reason to re-examine certain elements of the currently accepted fisheries management theory. As a result, this contribution may lead to a more solid theoretical foundation for fisheries management. This, of course, is the way any science is...
Thaler’s short paper is written to forecast the future of economics. The author states at the top that he will be subject to certain biases and also suggests good reasons why he will be subject to them. But, it turns out that the forecasts themselves are not supported by objective...
After two failed attempts to establish limited entry in its salmon fisheries,iii pursuant to legislation adopted by the Alaska Legislature in 1973, Alaska placed its primary salmon fisheries under limitation by 1975. Alaska persisted in seeking limited entry largely in response to declining salmon resources coupled with increasing levels of...
Dietary advice to the public about fat consumption has consistently emphasized the reduction of total fat,

The European Common Fisheries Policy landing obligation has introduced significant uncertainty over quota uptake in the coming years. This year (2016) is the first year of the landing obligation for fleets targeting demersal stocks even though it will not be fully introduced across demersal quota stocks until 2019. A recent...
The number of discussions about sustainable fisheries is increasing world-wide. The crisis in a lot of big fisheries, e.g. cod fishery on the Grand Banks, salmon fisheries along the pacific coast of the USA and Canada, must lead to different management regimes.
In the paper I describe different concepts for...
In late 1999 Artisanal Fisherman Association in Thailand requested the government to take actions in curbing destructive anchovy fishing gears. They believed that anchovy fishing was the main cause of fishery resource depletion in their fishing grounds. Main anchovy fishing gears were light luring falling net, purse seine, and scoop...
This paper considers the regulation of a natural resource within a dynamic common agency framework. In setting harvest quotas, the regulator responds to lobbying pressure (contributions) from harvesters and conservationists. The truthful Markov perfect equilibrium stock is then an increasing function of the effective political weight for conservationists. Since the...
There has been a growing interest in recent years in the potential use of product differentiation (through eco-type labelling) as a means of promoting and rewarding the sustainable management and exploitation of fish stocks.
