Fisheries models are generally built to assess the dynamics of a resource with a given fishing mortality
which level can be decided by some “decision maker” and/or which can be an observed process, e.g. times series proportional to some observed values of fishing effort. In these cases, the resource dynamics...
Resource rentals can be viewed as taxes on scarcity rents or as fees for access to use or utilize the
resource. The Icelandic Fishery Management Act requires that vessel owners pay a Catch fee
(Veiðigjald). This paper discusses how the Catch fee is defined by the Fishery Management Act.
Secondly...

These templates are used by a spreadsheet generator to create Excel spreadsheets that are probably free from a large class of errors, such as reference, omission, and type errors. We demonstrate how spreadsheets can be...
The estimation of standing crop is important in the management of rangeland resources. Direct measurements by clipping, drying, and weighing of herbaceous vegetation are time-consuming and labor-intensive. Therefore, non-destructive methods for efficiently and accurately estimating standing crop are needed in rangeland forage management. We assessed a visual obstruction (VO) technique...
Quota management systems (QMS) provide faith-based incentives for individual quota holders to conserve the resource voluntarily; quota holders expect the system to work and to be enforced and their expectations are usually realized despite imperfect incentives and significant enforcement burdens. Even with QMS there is never an individual incentive to...
Fishery villages (Van Chai) has been formed for about 300 years since pioneered fishers settled in Phan Thiet for their livelihoods. This was a original social professional organization found before official administrative system established.
Binh Thuan has more than 30 Van Chai in coastal areas, in which about 20 importantly...
This paper explores some theoretical and practical issues in developing policy for the management of shared fisheries for maximum value. Maximisation of value from the use of resources is a key component of sustainability, and transferable rights in commercial fisheries management have contributed significantly toward this goal. Maximising value becomes...
Maximizing profit and value added are central objectives when fishing rights are distributed. Financial profitability on a company level traditionally measures the return on total assets. Value added on the national level is the net (or gross) national product, and is the total profit of investments and wages and salaries...

Our paper adds to the growing body of conceptual work to show conditions under which a developing country that, in isolation, is unable to...
Using a general equilibrium model that has a resource (fisheries) sector and that incorporates subsistence consumption into consumer preferences, we examine the costs and benefits of participating in international trade. In some cases income transfers may permit potential, but otherwise unachievable, gains from trade to occur.
Thailand has been one of the most important fish exporting country, in spite of the degradation in her marine resources. Small scale fisheries accounted for more than 80 percent of the total marine fisheries households in this country. Fisheries had been considered the important source of food, income, employment and...
Salmon is one of the most successful aquaculture species measured in produced quantity and growth. The industry is highly export oriented, and creation of new markets has been instrumental for the industry's success. However, the rapid transformation of the markets due to the increased production has also led to a...
Traditional economic theory states that liberalising trade and moving to freer trade in conventional goods improves global welfare, as well as improving welfare in small countries. It also states that large countries only through the active use of their trade policies can maximise their welfare. However, these results are modified...

However, this concept has not been implemented in any fisheries aspects especially for the coastal fisheries, which have received a high pressure from fishing activities, industrial pollutions, household sewage, etc. Trammel net is...
Traditionally, fish has been considered as an item for direct or indirect human use (food, fertilizer, fishmeal and so on). Recently increasing number of studies on anadromous salmon in North America and Japan, however, suggest that fish could also support biodiversity. Marine-derived nutrients (MDN) are important contributors to maintain or...
Fisheries management has been carried out on the assumption that a fish population is in equilibrium with the fishing effort under the average environmental conditions and hence there must be a maximum sustainable yield (MSY). However, since the simultaneous rise and fall of the interdecadal and global scale of sardine...
