The IVQ regime in Norway: A stable alternative to an ITQ regime?

Since the introduction of quotas and licences as important management tools, Norway has insisted on an individual vessel quota regime (IVQ). The main argument has been to avoid market-based transactions of quotas and vessels and secure stability in regard to a diverse fleet structure and decentralized ownership of scarce cod resources. Thus, an individual transferable quota system (ITQ) with a high degree of transactions and the potential for a heavy concentration of quota ownership and fewer vessels has never been an alternative. However, since the late 80s, the trawler fleet has been trapped within a web of unprofitable overcapacity. Within the frame of a closed management regime and a path-dependent IVQ system, the quota regime has been forced towards a market-orientated system for transactions. In this article, we analyze the Norwegian IVQ system and discuss whether the aggregate effects of the IVQ regime are congruent with the models’ profound ideals.     

The Norwegian system and the distribution of claims to redfeed

Identifying competing interests and potential claims to a new marine resource, the plankton redfeed, which may be central as a solution to diminishing supplies of marine oils world wide, is critical prior to a commercial harvest thereof. The competing interests are found to be between those Norwegian fisheries organization taking an encompassing view of fisheries interests and those wanting more focus on the well-being of the coastal fishermen. Working within a corporatist setting, it is found, that interest organizations in Norway are included comprehensively by the national government in the decision-making process, but that the main group having the most power is Norges Fiskarlag, which will draw the quota distribution of a future redfeed harvest off shore and away from the coastal fishermen.

准噶尔盆地成藏动力学系统划分

本文在对成藏动力学系统的概念重新描述的基础上,选择经历了多旋回构造与沉积演化的准噶尔盆地进行成藏动力学系统划分。准噶尔盆地发育6套烃源岩、多套储集层、2套区域性盖层和数个局部盖层,它们构成6套生、储、盖组合。同时,钻井揭示盆地超压发育,结合测井与地震资料,将地层压力在垂向上划分为2个常压系统和3个超压系统。该盆地垂向通道众多,构造活动期流体上下连通性好,整体可划为一个复杂的成藏动力学系统。然而,断裂活动具幕式特征,相对盆地演化史,大部分时期处于静止封闭状态。因此,进一步将准噶尔盆地划分为6个成藏动力学子系统:①二叠系自源超压半封闭型成藏动力学子系统;②三叠系他源超压半封闭型成藏动力学子系统;③侏罗系混源超压半封闭型成藏动力学子系统;④白垩系—侏罗系混源常压开放型成藏动力学子系统;⑤古近系—白垩系混源超压封闭型成藏动力学子系统;⑥新近系他源常压开放型成藏动力学子系统。不同的子系统,成藏条件、成藏动力和成藏规律不同。     

Impacts of climate change on commercial fish stocks in Norwegian waters

The Norwegian fishing areas extend over various marine ecosystems that will respond differently to climate change. In the North Sea the productivity of the boreal fish species are likely to decrease under global warming and new warm-water species are expected to become more abundant. In the arctic marine ecosystem of the Barents Sea the fish productivity is expected to increase and their distributions expand northward and eastward under global warming increasing the importance of the Russian as well as the Norwegian sectors of the Barents. In the past, decadal-scale climate variations have been shown to strongly influence productivity and distributions of fish stocks. The importance of such shorter-term variations are expected to continue also under global warming. Under global warming the optimum temperature for fish farming along the Norwegian coast will be displaced northwards from the northern part of West Norway towards the Helgeland coast.     

Multi-stakeholder perspectives on the use and influence of “grey” scientific information in fisheries management

Scientific information on the shrimp and groundfish resources of the Brazil–Guianas continental shelf has been produced by the United Nations Food and Agriculture Organization (FAO) and the Caribbean Regional Fisheries Mechanism (CRFM), in collaboration with the national governments exploiting the resources, since the early 1970s. In spite of the availability of such information, largely as grey literature, there is limited evidence as to the extent it is being used in fisheries management in Trinidad and Tobago. The flow of information between multiple stakeholders − fishing industry, scientists, fisheries managers, policy makers, and fisheries advisory bodies − was studied based on responses to a survey of key individuals to document each of their roles in the creation, distribution, and use of fisheries information. Content analysis of responses was completed to determine the opportunities and barriers for using scientific information in fisheries management. Salience, credibility, and legitimacy of the information were shadowed by barriers that decreased these attributes. Knowledge about the fishery has increased and technical capabilities have been strengthened through research. At the same time, advances in digital technology have made information more accessible. Yet, the high technical content of fisheries information reduced its usefulness to some stakeholders and formal systems do not exist for distributing or measuring the use and influence of such information in decision making. Communication strategies to promote awareness of the scientific information and aligning scientific information with fisheries policy could increase its use and influence. Institutional support for partnerships and education to encourage stakeholder involvement could also facilitate increased influence of scientific information.     

Quota discarding and distributive justice: The case of the under-10 m fishing fleet in Sussex,England

Marine fish discarding has become a contentious environmental issue, but little attention has been paid to the moral grievances that sometimes underlie discarding practices. This article explores such a moral grievance through a case study of the under-10 m fishery in Sussex, England, where discarding of cod (Gadus morhua) has become a highly charged issue, skippers blaming it on unjust quota allocations. The moral claim to a greater quota allocation is analysed using two conceptions of distributive justice, entitlement and desert. The conclusion reached is that the under-10 m fleet’s entitlement arguments for a higher quota are weaker than their desert arguments, but that entitlement arguments weigh more heavily than desert arguments with government when it allocates quota.     

Administrative aspects

In an article published in Marine Policy a year ago, (Lynne and Brian Chatterton, ‘How much political compromise can fisheries management stand’, Vol 5, No 1, April 1981), it was argued that management of South Australian coastal fisheries reflected the political ideology of the government in power, rather than the biological and socioeconomic imperatives of the resource. In the first article below, A.M. Olsen, former Director of Fisheries, criticizes the Chattertons' conclusions, maintaining that fisheries should be managed by professionals not politicians and that many of Brian Chatterton's problems during his tenure as Minister of Fisheries were of his own making. In the Chattertons' response, they point out that by allocating management of the resource between various vested interests (including government bureaucracy) a minister is making a political decision. In the third article, R.D. Walkerden, a former Permanent Secretary to Fisheries Ministers in South Australia, offers an administrator's view of the controversy. Detailed and parochial as some of the points at issue appear, the debate provides an illuminating view of some of the ideological and organizational conflicts that can hinder the effective management of a coastal resource.
