This paper examines the recurring theme that fisheries management ought to emulate the institutional arrangements governing other natural resources, such as public rangelands. Overly facile comparisons between fisheries and range have been based on a misguided vision of range policy and an obsession with the structure of property rights. The result has been a condition of “structural narcosis” that obscures obvious but important differences between range and fisheries and obstructs more productive and sophisticated attempts at comparative inquiry. This paper provides a more detailed contrast between past range and current fisheries policy in the United States, in pursuit of more realistic lessons for policy makers. Range management, the paper concludes, is evolving in directions that are instructive for fisheries, but the crossing of conceptual boundaries between these two resources must be undertaken with care and greater attention to detail. 相似文献

Ninteen species of subfamilies Imbricariinae and Cylindromitrinae, family Mitridae, are recorded from the China＇s seas. Of which, one genus and six species are recorded for the first time from China＇s seas, i.e., genus Ziba Adams H and Adams A, Cancilla （Cancilla） carnicolor, Ziba duplilirata, Z. insculpta, Neocancilla circula, Scabricola （Scabricola） desetangsii, Scabricola （Swainsonia） ocellata ocellata. 相似文献

The use of a system of continuous culture of phytoplankton at constant population density, the ‘cage-culture’ turbidostat, as a monitor of the bioavailability of pollutant materials, is illustrated. In the case of proposed dredge spoils from two polluted areas, it is shown that bulk analyses for scheduled materials cannot be equated with bioavailability. Monitoring for the effect of the whole pollutant mixture on a properly chosen test population could obviate the necessity for chemical analyses for each component. 相似文献

1 IntroductionThe family Mitridae mainly distributes in tropicaland subtropical regions, particularly in the Indo—Pa-cific Ocean. Up to date, nearly 500 species have beendescribed in the world (Cernohorsky, 1976, 1991). InChina, the taxomonic and faunal research is very poor.Kuroda (1941) recorded 71 species from Taiwan, Chi-na (22 of them belong to the genus Vexillinae, which isplaced in family Costellariidae now as the species ofthis genus all have prominent axial cords or grooves onthe… 相似文献

This article gives a Parliamentary view of how fisheries policy in the European Community may develop now that Europe has a Common Fisheries Policy. The focus should now change from the tension of Council of Ministers meetings to the proper development of the European Commission's executive role and the effective monitoring of the bureaucracy by the democratically elected European Parliament. 相似文献

The ambient noise produced by large areas of ice floes, such as the Odden and the marginal ice zone, was recorded and analysed. A model based on the collision, compression and shearing of floes driven by ocean swell was constructed. This model allows the level and variance of the ambient noise to be predicted provided the conditions of the ice and the sea state are known. The frequency spectrum of the ambient noise in the range 100 Hz to 100 kHz is explained in terms of acoustic propagation and absorption by sea water. The probability distribution of ambient noise intensity, obtained from a statistical analysis of collision frequencies, is a form of K distribution and agrees with observations. 相似文献

This paper reports on progress in developing a regional research and education strategy for Pacific Island countries and communities wishing to transition to a low carbon sea transport future. Sea transport is an absolute necessity for most such communities. All current services are fossil fuel based and are becoming increasingly unaffordable and unsustainable. The countries in the Pacific region are the most dependent on imported fossil fuels in the world, importing more than 95% of needs. Such dependency is having a crippling effect on national budgets and major impacts on key productive sectors. The region's transport issues are unique; small and vulnerable economies scattered at the ends of some of the longest transportation routes in the world and arguably the most challenging to maintain per capita and per sea mile. Alternatives to current fossil fuel powered sea transport have been almost totally ignored in recent regional and national debates and the issue has been largely invisible within the policy and donor strategy space at all levels despite concerted efforts over more than two decades to transition Pacific countries' electricity sector fossil fuel use. The University of the South Pacific has been collaborating with a network of stakeholders and knowledge partners since 2012 to advance this agenda, building off previous doctoral research and the resultant Sustainable Sea Transport Talanoa 2012. Prasad et al. (2013) set out the basis for a catalytic research program following from the consensually agreed outputs of SSTT 2012 and this paper records the progress made since. 相似文献

Gabriel T. Csanady turned 80 in December 2005 and we celebrate it with this special Progress in Oceanography issue. It comprises 20 papers covering some of the many areas that Gabe contributed significantly throughout his professional career. In this introductory paper we briefly review Gabe’s career as an engineer, meteorologist and oceanographer, and highlight some of his major contributions to oceanography, both as a scientist as well as an educator. But we also use this opportunity to remember and thank Gabe, and his wife Joyce, for being such good friends and mentors to several generations of oceanographers. The authors of the collection of papers in this volume deserve special thanks for their efforts. We also are pleased to acknowledge the support of Progress in Oceanography’s editor, Detlef Quadfasel, and the many anonymous reviewers who generously contributed their time and expertise. 相似文献

Despite the importance of the socio-economic dimension of the use of marine waters, there has been little research in the field until recently, when interest has grown in the concept of ‘blue growth'. This paper aims to contribute to filling this gap with a socio-economic assessment of the main maritime sectors, focused on the Spanish part of the European Atlantic Arc. To this end, it first proposes a theoretical structure for the maritime economy and then collects and classifies comparable and reliable maritime socio-economic indicators. The data obtained allows us to assess the size of the Spanish maritime sector and the position of the Spanish Maritime Cluster in the wider context of the maritime economy of the European Atlantic, as well as discuss the appropriateness of a strategy of forming clusters at the national level vs. a transnational approach. The results indicate differences between regions in the European Atlantic Arc that complicate the development of integrated policies to stimulate blue growth. Extending our knowledge of the maritime economy of the European Atlantic Arc will make it possible to design strategies that address the real issues, increasing the likelihood of these being effective. 相似文献

The original prognostic equations for the JONSWAP-spectrum contained inconsistencies. A subsequent paper (Hasselmann et al., 1976, J. phys. Oceanogr.6, 200–208) attempted to regularise the situation. This paper shows that there were still inconsistencies in the prognostic equations giving overestimations of the first moment of the spectrum and consequently the significant wave height. The prognostic equations are reworked systematically and results presented. It is shown that variable σa, σb and γ must be used to achieve consistent results 相似文献
