The population of adult perch in the Baltic Sea consists of a number of spawning populations. Spawning migration is different in different tagging places. Perch were marked with Carlin tags during the spawning period and released after tagging in the area where they had been caught. In Helsinki sea same...
In 2011 an individual fishing quota (IFQ) system was implemented for the limited entry trawl component of the Pacific groundfish fishery in the US. The IFQ system allocates quota shares (QS) for 29 IFQ stocks and individual bycatch quota (IBQ) shares for Pacific halibut. Each year quota shareholders are issued...
The harvesting strategies in open access marine fishery and marketing patterns of marine products have
undergone rapid structural changes in the post liberalisation era of the Indian Economy. There is a
continuous increase in demand and price of the fish both in domestic and export markets and the thrust on...
Although widely accepted, management systems that directly restrict catch or effort are neither efficient nor desirable for many fisheries, and have failed to conserve fishery stocks in many cases. Fisheries scientists have suggested that closing part of the fishery with marine reserves may sustain or increase harvest. These marine reserves...
This paper presents a critical analysis of the provisions of the WTO agreements and jurisprudence as they relate to the use of trade-related measures in support of cooperative fisheries management arrangements. The interpretation given to WTO agreements by successive Panels and Appellate Bodies has provided guidance regarding how such measures...
Most trade literature is concerned with gains from free trade under the assumption that traded goods are produced under complete property rights. Seldom have researchers examined the consequences of free trade in the presence of incomplete property rights over renewable natural resources. In this paper, we explore these consequences. In...
When several new species are introduced into the New Zealand Quota Management System in the near future, some of the quota, or single-year annual catch entitlement (ACE), will be tendered through competitive auctions rather than allocated based on historical catch. This study uses a laboratory experiment calibrated to a representative...
Generalised linear estimation and multi-layer perception neural network modelling techniques were applied to the Scottish trawler fleet data in order to estimate which inputs have the greatest impact on boat profits and output. Both produced comparable estimates that revealed inelastic and non-linear response to vessel power and length, negative response...
It is rarely possible or desirable to maintain a constant target fishing mortality rate for each individual stock in a multispecies fishery. Preventing overfishing of all stocks at all times will often be in conflict with attainment of optimal yield for the fishery. This paper presents a retrospective analysis and...
Access restrictions to traditionally-used resources, that are associated with the establishment of marine protected areas (MPA), often generate conflicts. Public participation in decision-making process has been widely recognised as a critical factor in legitimising conservation policy and enhancing its success. This paper discusses fishers involvement issues in the context of...
