Using catch rate data for simple cost-effective quota setting in the Australian spanner crab (Ranina ranina) fishery.

For many fisheries, there is a need to develop appropriate indicators, methodologies, and rules for sustainably harvesting marine resources. Complexities of scientific and financial factors often prevent addressing these, but new methodologies offer significant improvements on current and historical approaches. The Australian spanner crab fishery is used to demonstrate this. Between 1999 and 2006, an empirical management procedure using linear regression of fishery catch rates was used to set the annual total allowable catch (quota). A 6-year increasing trend in catch rates revealed shortcomings in the methodology, with a 68% increase in quota calculated for the 2007 fishing year. This large quota increase was prevented by management decision rules. A revised empirical management procedure was developed subsequently, and it achieved a better balance between responsiveness and stability. Simulations identified precautionary harvest and catch rate baselines to set quotas that ensured sustainable crab biomass and favourable performance for management and industry. The management procedure was simple to follow, cost-effective, robust to strong trends and changes in catch rates, and adaptable for use in many fisheries. Application of such “tried-and-tested” empirical systems will allow improved management of both data-limited and data-rich fisheries.

Duckweed-based Wastewater Treatment Systems: Design Aspects and Integrated Reuse Options for Queensland Conditions

Point sources of wastewater pollution, including effluent from municipal sewage treatment plants and intensive livestock and processing industries, can contribute significantly to the degradation of receiving waters (Chambers et al. 1997; Productivity Commission 2004). This has led to increasingly stringent local wastewater discharge quotas (particularly regarding Nitrogen, Phosphorous and suspended solids), and many municipal authorities and industry managers are now faced with upgrading their existing treatment facilities in order to comply. However, with high construction, energy and maintenance expenses and increasing labour costs, traditional wastewater treatment systems are becoming an escalating financial burden for the communities and industries that operate them. This report was generated, in the first instance, for the Burdekin Shire Council to provide information on design aspects and parameters critical for developing duckweed-based wastewater treatment (DWT) in the Burdekin region. However, the information will be relevant to a range of wastewater sources throughout Queensland. This information has been collated from published literature and both overseas and local studies of pilot and full-scale DWT systems. This report also considers options to generate revenue from duckweed production (a significant feature of DWT), and provides specifications and component cost information (current at the time of publication) for a large-scale demonstration of an integrated DWT and fish production system.

Fascinating and forgotten, the conservation status of marine elapid snakes

An assessment of marine elapid snakes found 9% of marine elapids are threatened with extinction, and an additional 6% are Near Threatened. A large portion (34%) is Data Deficient. An analysis of distributions revealed the greatest species diversity is found in Southeast Asia and northern Australia. Three of the seven threatened species occur at Ashmore and Hibernia Reefs in the Timor Sea, while the remaining threatened taxa occur in the Philippines, Niue, and Solomon Islands. The majority of Data Deficient species are found in Southeast Asia. Threats to marine snakes include loss of coral reefs and coastal habitat, incidental bycatch in fisheries, as well as fisheries that target snakes for leather. The presence of two Critically Endangered and one Endangered species in the Timor Sea suggests the area is of particular conservation concern. More rigorous, long-term monitoring of populations is needed to evaluate the success of "conservation measures" for marine snake species, provide scientifically based guidance for determining harvest quotas, and to assess the populations of many Data Deficient species.

Evidence of package trading in a mature multi-species ITQ market

In multi-species fisheries managed under ITQs, the existence of joint production may lead to complex catch-quota balancing issues. Previous modelling and experimental research suggest that, in such fisheries, some fishers may benefit from the ability to trade packages of fishing quotas, rather than fulfil their quota needs by simultaneously bidding on separate single-species quota markets. This note presents evidence of naturally occurring package trades in a real fishery. Based on this evidence, we suggest that further empirical and modelling research is required on the potential and limitations of package quota trading in mixed fisheries managed with ITQs. © 2014.

Tasa-arvo ja muutoksen rajat : Sukupuolten tasa-arvo poliittisena ongelmana Ranskan parité- ja Suomen kiintiökeskusteluissa

The study looks at the debates on gender equality in political decision-making in Finland and France in the 1990s and 2000s by analysing the argumentation for parité and quotas and the ways in which gender equality was constructed as a political problem. The focus of the study is on the parliamentary debates on the amendment of the electoral law in France in 2000 and the introduction of quota regulations into the Act on Equality in Finland in 1994 - 1995. The debates ended in the adoption of quota regulations in the electoral lists (France) and in the executive and preparatory bodies at the national and the local level (Finland). Apart from the analysis of the parliamentary debates, the study explores the political processes preceding the adoption of legislation as well as the debates on quotas and parity in Finnish and French societies in the 1980s and 1990s. The debates on gender equality are analysed as the sites of struggle and change with regard to the normative boundaries of gender equality, as well as of politics and citizenship. The cross-cultural perspective gives room to explore the ways in which gender equality and change can be imagined in different national contexts, and which kinds of discursive resources are available for the politicization of gender equality. Specific attention is paid to the discursive frames and agenda settings in the debates and how these set the limits of the imaginable and the possible in the promotion of gender equality. In both Finland and France, the promotion of equality was constructed as a national project, in which the main beneficiary was the society or the nation as a whole. In France, gender equality was an inherent part of the promotion of French democracy; in Finland, gender equality was regarded as a means to bring the expertise of both women and men to the benefit of the whole society. Furthermore, in both countries the promotion of gender equality was based on the harmonious cooperation of women and men and the temporal dimension of "nearly achieved" gender equality. In this kind of a context, gender equality served as a means towards the wider national ends, and there was little room to discuss the aspects of power and agency with regard to gender equality. However, the internationalisation of equality politics, as well as the conflicting interpretations of gender equality in the national political arenas, calls into question the existence of clearly defined and immutable boundaries of "Finnish" and "French" gender equality. At the same time, the rules of the game in politics, including the meaning of French republicanism and Finnish "expert oriented" politics were contested. In this way, the new equality legislation and the preceding political processes played a part in the transformation of the limits of gender equality, politics and citizenship.

Correcting trade distortions in a small open economy

This paper considers the second-best strategy of correcting a wide variety of trade distortions in a small open economy with perfect competition in all markets. Using the tools of duality, we obtain some general properties of the structure and the levels of the optimal taxlsubsidy rates. The paper also analyzes the welfare effects of unilateral piecemeal trade policy reforms when some of the quota distortions—imposed by the foreign countries—are unalterable. It is shown that the merits of unilateral trade policy reforms that are emphasized in the literature crucially depend on the absence of unalterable foreign imposed quotas.

Welfare effects of aid under quantitative trade restrictions

The paper examines the effects of tied-aid on the welfare of both the donor and the recipient countries. We depart from the previous literature by assuming preexistence of quantitative trade distortions. To mitigate these distortions the donor country provides aid that is tied to the rationed good. Conditions for the presence of the transfer paradox and of the enrichment of both countries are derived and interpreted under the stability of the system. Furthermore, we show that whereas untied aid cannot increase global welfare, tied-aid unambiguously does so.

Gender, Politics and Democratisation in Cameroon

Gender perceptions, religious belief systems, and political thought have excluded women from politics, for ages, around the world. Combining feminist and modernisation theorists in my theoretical framework, I examine the trends in patriarchal Europe and I highlight the gender-sensitive model of the Nordic countries. Retracing local gender patterns from precolonial to postcolonial eras in sub-Saharan Africa, I explore the links between perceptions, needs, resources, education and women's political participation in Cameroon. Democratisation is supposed to open up political participation, to grant equal opportunities to all adults. One ironic feature of the liberalisation process in Cameroon has been the decrease of women in parliamentarian representation (14% in 1988, 6% in 1992, 5% in 1997 and 10% in 2002). What social, cultural and institutional mechanisms produced this paradoxical outcome, the exclusion of half the population? The gender complementarity of the indigenous context has been lost to male prevalence privileged by education, church, law, employment, economy and politics in the public sphere; most women are marginalised in the private sphere. Nation building and development have failed; ethnicism and individualism are growing. Some hope lies in the growing civil society. From two surveys and 21 focus groups across Cameroon, in 2000 and 2002, some significant results of the processed empirical data reveal low electoral registration (34.5% women and 65.9% men), contrasted by the willingness to run for municipal elections (33.3 % women and 45.2% men). The co-existence of customary and statutory laws, the corrupt political system and fraudulent practices, contribute to the marginalisation of women and men who are interested in politics. A large majority of female respondents consider female politicians more trustworthy and capable than their male counterparts; they even foresee the appointment of a female Prime Minister. The Nordic countries have institutionalised gender equality in their legislation, policies and practices. France has improved women's political inclusion with the parity laws; Rwanda is another model of women's representation, thanks to its post-conflict constitution. From my analysis, Cameroonian institutions, men and more so women, may learn and borrow from these experiences, in order to design and implement a sustainable and gender-balanced democracy. Keywords: democratisation, politics, gender equality, feminism, citizenship, Cameroon, Nordic countries, Finland, France, United Kingdom, quotas, societal social psychology.

Uma breve discussão sobre os sistemas de cotas no Brasil : fragilidades e desafios

Problematiza, a partir de pesquisa bibliográfica e documental, a utilização do sistema de cotas raciais na realidade brasileira. Conclui que, apesar da importância da adoção de mecanismos que viabilizem a diminuição da desigualdade e a erradicação da discriminação, é necessário aprimorar o debate e valorizar o contexto interno como base de desenvolvimento de alternativas metodológicas para as ações afirmativas.

Ausência de política pública de cotas raciais para ingresso em instituições públicas de ensino superior no Brasil

Descreve o atual panorama normativo para as cotas raciais no Brasil com base em estudo realizado com utilização de a análise documental e bibliográfica. Os resultados indicaram que a ausência de uma norma federal implicou baixa adesão ao sistema de cotas, o que é ratificado pelo insignificante número de Instituições Públicas de Ensino Superior (Ipes) que adotaram norma de cota racial - apenas 17,79%. Verificou-se, ainda, que essa ausência cria lacunas na adoção de diretrizes nacionais para a interpretação e a compreensão das ações afirmativas. Tais lacunas refletem diretamente no ciclo da política pública, comprometendo a avaliação e o acompanhamento da efetividade e do sucesso da política, o que é extremamente perigoso para a segurança jurídica na área de direitos humanos e para a garantia da equidade de fato nos espaços político, econômico e social.

Improvements to Data Collection in Commercial Fisheries Using Electronic Reporting Methods: Cost/Efficiency and Implications for Use in Ecosystem Management.

Data have been collected on fisheries catch and effort trends since the latter half of the 1800s. With current trends in declining stocks and stricter management regimes, data need to be collected and analyzed over shorter periods and at finer spatial resolution than in the past. New methods of electronic reporting may reduce the lag time in data collection and provide more accurate spatial resolution. In this study I evaluated the differences between fish dealer and vessel reporting systems for federal fisheries in the US New England and Mid-Atlantic areas. Using data on landing date, report date, gear used, port landed, number of hauls, number of fish sampled and species quotas from available catch and effort records I compared dealer and vessel electronically collected data against paper collected dealer and vessel data to determine if electronically collected data are timelier and more accurate. To determine if vessel or dealer electronic reporting is more useful for management, I determined differences in timeliness and accuracy between vessel and dealer electronic reports. I also compared the cost and efficiency of these new methods with less technology intensive reporting methods using available cost data and surveys of seafood dealers for cost information. Using this information I identified potentially unnecessary duplication of effort and identified applications in ecosystem-based fisheries management. This information can be used to guide the decisions of fisheries managers in the United States and other countries that are attempting to identify appropriate fisheries reporting methods for the management regimes under consideration.

Greenland turbot Reinhardtius hippoglossoides of the eastern Bering Sea and Aleutian Islands region

Greenland turbot (Reinhardtius hippoglossoides) is a commercially important flounder in both the North Atlantic and North Pacific Oceans. In the latter, its center of abundance is in the eastern Bering Sea and along the Aleutian Islands chain where its population is managed as a single stock. Harvest levels in this region of the North Pacific during the period 1970-81 were comparable with those in the northwest and northeast Atlantic, with annual average catches of 53,000 metric tons (t). However, the catch in 1984 dropped sharply to 23,100 t, in part because of reduced quotas arising from concern over continued poor recruitment and declining catch-per-unit-effort. Recruitment failure was manifested in 1) the sharp decline in the catch rate of young flsh in annual research trawl surveys on the continental shelf of the eastern Bering Sea and 2) an increasing proportion of older and larger fish in the commercial catch from the continental slope of both the eastern Bering Sea and Aleutian Islands. The cause ofthe decline in recruitment could not be clearly identifled. Greenland turbot of the Bering Sea-Aleutian Islands share certain distributional features with the North Atlantic form. There is an apparent bathymetric change in the size and age of fish, with younger animals occupying continental shelf depths and the older individuals residing at depths of the continental slope. At shallow depths the young are exposed to temperature fluctuations, whereas older animals along the slope are exposed to relatively stable temperatures. A hypothesis is proposed for describing the temporal and spatial paths by which young animals reach the mature or spawning portion of the population. (PDF file contains 38 pages.)

Begrenzung des Fischereiaufwandes oder Erhöhung der Mindestmaschenöffnung – Ein Vergleich der Alternativen bei der Dorschfischerei in der Ostsee

The basis for a long-term profitable fishery is a precautionary and environment-compatible use of fish stocks. The fishery management presently models the exploitation through the parameters of fishing mortality and the age at first capture. These two parameters are translated into the technical measures of fishing effort and mesh openings and quotas, which are then used in practice for controlling the fishery. Stock protection can be achieved by reducing the fishing effort, by assigning smaller quotas, by reducing the number of days at sea, or by increasing the mesh opening. The respective protection measures have different effects on the development of the stocks but also on the revenue obtained by the fishery. These alternatives have been examined taking as an example the cod stock in the western Baltic. The optimization goal was the maximization of profit observing at the same time the prerequisites for stock protection according to the precaution approach. For these calculations the same models and data have been used as are beeing used in the stock management of the ACFM of ICES. The response of altered technical measures to the recruitment of cod stock was considered, and a proposal to overcome overfishing of cod in the western Baltic Sea was derived.
