Some recent studies have shown the outstanding price linkages at the global scale between the cannery-grade
tuna markets over the last decade. When it comes to price transmission along the European value chains, opposite results between the two major species (skipjack and yellowfin) are found: the market for final goods...
Knowledge workers need to find information but even when it is stored on their local computer systems, finding it can be costly. There are many researchers working on solutions to reduce these costs, but there has been little research into exactly what these costs are, and what the ties are...
In multispecies fisheries managed with individual fishery quotas (IFQs), fishers targeting certain species often have
insufficient quota to cover other jointly caught species. New Zealand employs a unique dual price-quantity system to
address this problem. In lieu of acquiring quota, fishers can opt to pay a fee per unit of...

Improved legal framework, financing, human resources and technologies are required for...
Japanese salmon fishery is facing a juncture of existence and pressed for the improvement of constitution. The decline of high-seas salmon fisheries was taken and the import amount increased rapidly. In addition, domestic production by coastal set net fisheries has increased with a success of salmon enhancement in Japan. Salmon...
A bioeconomic model allowing different degrees of harvesting closures for two sub-stocks consisting of mature and immature fish is presented. Hence the model opens for partial closures of fisheries on both sub-stocks. Migration between the two sub-stocks is defined as recruitment of the young to the mature sub-stock, and egg...
Using a partial adjustment modeling (PAM) approach, this paper examines the behaviour of Japanese import demand for Indian seafood products during the period January 1995-March 2000. It was found that lag demand, income, seasonality and time trend significantly influencing the import demand behaviour of Japan for the Indian seafood products....
The auction system is rather rare in the world fisheries. During this three-year period, 2001-2003, fish quotas in the RFE and the North (Barents Sea) were auctioned off, with the by far largest volumes in the RFE. The main purpose of auctioning quotas for fish and marine invertebrates was to...

In this type of fish farming domestic and industrial sewerage discharged from bug metropolis are utilized for fish farming. Utilization of sewerage for fish farming has been an alternative for treatment. As installation of sewerage treatment plants...
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...
Atlantic Sea scallops have historically supported the second most valuable fishery in the northeastern United States. Intense fishing pressure during the early 1990s led to drastic decreases in population biomass and commercial landings. Total harvest, which exceeded 17,000 metric tons (MT) in 1990, declined to around 7,300 MT in 1993....
