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...
Ocean temperatures are expected to rise over the next decades. This is likely to affect the distribution of fish stocks between the exclusive economic zones (EEZs) of different countries. Such changes are likely to be triggered as temperatures rise beyond certain threshold levels, and they are likely to be irregular,...
Since 1950, the real value of fish catches in Norway has about doubled, while the number of fishermen has declined by about 85 percent. This has made it possible to maintain fishermen's incomes roughly on par with other occupational groups in Norway. It is investigated to what extent this increase...
The relative efficiency of landing fees versus quota controls to achieve given escapement levels is examined. The criterion is profit per year over a given time horizon. The model employed is a discrete version of the logistic model where growth is influenced by a random variable. Simulations are used to...
Weitzman (2002) has shown that with a stochastic growth function and uncertainty in estimating stock size, landing fees will be superior to quotas as a means of controlling fish harvest. Hannesson and Kennedy (2003) expand the analysis by considering variable availability of fish, random fish prices, and non-constant returns to...
Present resource rents in Norway's fisheries were compared for different fleet structures. Alternative values of TACs were assumed, which is consistent with how most fisheries in Norwegian waters are managed. Total allowable catches (TACs) are set on the basis of advice by fisheries biologists where the economics of the industry...
Quotas rather than landing fees are widely used for reducing the output of fisheries below open-access levels. One reason may be that quotas are perceived as a more reliable instrument for controlling total catch. However, whilst under certainty fees and quotas can be set each season to achieve the same...
The potential for achieving sustainable and efficient harvesting of three species of migratory tuna in the
Western and Central Pacific Ocean is examined. The stocks reside in exclusive economic zones (mainly those of Pacific island countries) and in the high seas. Most harvesting is carried out by distant water fishing...
