    Description: The promotion of mega-constructions, as reservoirs of Itaipu and Yacyretá, are based in ideas of development and progress. However, the report showed by the World Commission on Dams (WCD) in November of 2000, made responsible to the big reservoirs, the projects on Sustainable Regional Development (SRD), as generating of social and environmental damages. Thus, the main goal of the present study is to investigate the social and cultural transformations in the communities of the islanders and riparian people from Ituzaingó and Porto Rico with the constructions of the hydroelectric power plants of Itaipu (Brazil), Porto Primavera (Brazil) and Yacyretá (Argentina). Are analyzed many factors that allowed the built of those reservoirs and their principal actors. Also, the contradictions more visible verified in the social community and environmental of Ituzaingó and Porto Rico. The three reservoirs are located on the Paraná River basin, because the exploration of there hidroelectrical potential and promote of development of the different regions. Although, the reservoirs of Itaipu and Yacyretá, as projects of DRS, not allowed better social conditions for the traditional communities of Porto Rico and Ituzaingó, and they were made loose their significance when they are compare with the damages caused. In the other hand, its main beneficiaries are the multilateral financiers agencies and the economical trusts with distant headquarters from the south of Brazil and the northeast of Argentina.
    Description: A aceitação e promoção de megaobras, como as barragens de Itaipu e Yacyretá, são baseadas em idéias de desenvolvimento e de progresso. Contudo, o informe apresentado pela Comissão Mundial de Represas (CMR) em novembro de 2000, responsabilizou às grandes represas, os projetos de Desenvolvimento Regional Sustentável (DRS) por excelência, como geradoras de uma série de danos sociais e ambientais. Destarte, o objetivo do presente trabalho foi o estudo das transformações sociais ocorridas nas comunidades de ilhéus e ribeirinhos de Ituzaingó e Porto Rico a partir das mudanças na paisagem ecológica decorrentes das construções das usinas hidrelétricas de Itaipu (Brasil), Porto Primavera (Brasil) e Yacyretá (Argentina). Com essa finalidade foram analisados alguns dos fatores que possibilitaram a concretização desses projetos assim como a identificação dos seus principais protagonistas. O trabalho também contemplou o resgate das vozes dos pescadores-lavradores da região. As três usinas assentam-se sobre o rio Paraná com o propósito de explorar o seu potencial hidrelétrico e estimular o desenvolvimento das respectivas regiões. Porém, as represas de Itaipu, Porto Primavera e Yacyretá, como projetos de DRS, não promoveram, até hoje, melhoras significativas para as comunidades tradicionais de Porto Rico e Ituzaingó. O desenvolvimento alcançado perde toda importância quando comparado aos prejuízos ocasionados. Paradoxalmente, os seus principais beneficiários são as agências financiadoras multilaterais e os consórcios econômicos com sedes distantes do sul brasileiro e do nordeste argentino.

    Description: 1. Interactions between cetaceans and fishing activity in the Archipelago of the Azores were examined using information contained in grey literature and previously unpublished data collected by observer programmes and research projects from 1998 to 2006. Together with a brief description of the economics, gear, fishing effort, and past and ongoing monitoring projects, levels of cetacean bycatch and interference were reported for each major fishery. 2. Cetaceans were present in 7% (n=973) and interfered in 3% (n=452) of the fishing events monitored by observers aboard tuna-fishing vessels. Interference resulted in a significantly higher proportion of events with zero catches but it was also associated with higher tuna catches. 3. There was a decreasing trend in the proportion of tuna-fishing events with cetacean presence or interference throughout this study, as well as a reduction in the estimates of dolphins captured annually by the whole fleet. 4. Observers reported cetacean depredation in 16% of the sets for demersal species and in 2% of the sets for swordfish. Cetacean presence and depredation were associated with higher overall catches and higher catches per unit effort in demersal fisheries. Bottlenose dolphins (Tursiops truncatus) were responsible for most depredation events in demersal fisheries, whereas in the swordfish fishery, depredation was associated with the presence of killer whales (Orcinus orca). There were no reports of cetacean bycatch in these fisheries. There were also no reports of cetaceans interacting in the experimental deep-sea fisheries that were examined. 5. Available data suggests that levels of interaction between cetaceans and Azorean fisheries are generally low and that the economic impact of cetacean interference is probably small. However, for several traditional fisheries there are no accurate data to determine levels of cetacean interaction. We recommend that existing observer programmes be expanded to increase observer coverage of the demersal and swordfish fisheries and allow monitoring of other existing and emerging fisheries.

    Description: The longfin squid Loligo pealeii is distributed widely in the NW Atlantic and is the target of a major fishery. A previous electrophoretic study of L. pealeii was unable to prove genetic differentiation, and the fishery has been managed as a single unit stock. We tested for population structure using 5 microsatellite loci. In early summer (June), when the squids had migrated inshore to spawn, we distinguished 4 genetically distinct stocks between Delaware and Cape Cod (ca. 490 km); a 5th genetic stock occurred in Nova Scotia and a 6th in the northern Gulf of Mexico. One of the summer inshore stocks did not show genetic differentiation from 2 of the winter offshore populations. We suggest that squids from summer locations overwinter in offshore canyons and that winter offshore fishing may affect multiple stocks of the inshore fishery. In spring, squids may segregate by genetic stock as they undertake their inshore migration, indicating an underlying mechanism of subpopulation recognition.

    Description: From the Forward: The idea for an Exploratory Workshop on Fisheries Sociology emerged from informal discussions held at the 1983 Rural Sociological Society meetings. Planning for the Exploratory Workshop was undertaken by the two of us (Bailey and Harris) with the assistance of Peter Sinclair and Christopher Vanderpool. We sought to identify persons working in different areas of the sociology of fisheries who could present review papers on their areas of inquiry. The papers in this volume are the result of that effort. At the same time, we sought to identify persons who would be interested in attending such a workshop• By combining our personal networks, the mailing list of the Fisheries Anthropologist at the National Marine Fisheries Service (Peter Fricke), and the list of attendees at two sessions on fisheries organized by Bailey at the 1984 Rural Sociological Society meetings, we developed a mailing list of 83 sociologists working on some aspect of fisheries. Invitations to attend the workshop were sent to those persons. In response to the invitation, 24 sociologists attended the Workshop. They came from eleven states, the District of Columbia and Puerto Rico, three provinces of Canada, and Norway. They represented work in both industrialized and developing nations, in subsistence, recreational and commercial fisheries, and in aquaculture.

    Description: No-take marine reserves are widely recognized as an effective conservation tool for protecting marine resources. Despite considerable empirical evidence that abundance and biomass of fished species increase within marine reserve boundaries, the potential for reserves to provide fisheries and conservation benefits to adjacent waters remains heavily debated. This paper uses statistical and population models to evaluate published empirical data on adult spillover from marine reserves and shows that spillover is a common phenomenon for species that respond positively to reserve protection, but at relatively small scales, detectable on average up to 800 m from reserve boundaries. At these small scales, local fisheries around reserves were likely unsustainable in 12 of 14 cases without the reserve, and spillover partially or fully offsets losses in catch due to reserve closure in the other two cases. For reserves to play a role in sustaining and replenishing larger-scale fished stocks, networks of reserves may be necessary, but as few exist this is difficult to evaluate. The results suggest reserves can simultaneously meet conservation objectives and benefit local fisheries adjacent to their boundaries.

    Description: This bibliography of social and economic studies of the fisheries of the Northeast United States (Maine to North Carolina) includes annotated listings for each entry and an index of key words for cross-referencing. We have attempted to include all studies published since 1970, and a selected group of particularly significant studies done earlier. The major focus has been on commercial fisheries, but recreational fishing studies have also been included when possible. In addition to studies of the Northeast United States fisheries, studies of Canadian fishing subsidies, European and other markets, have been included because of their relevance to the regional industry. All stages of the fishing industry's operation - harvesting, processing, distribution, marketing - are included, along with management and policy oriented material.

    Description: The New England fishing industry is examined in terms of the capacity of the fishing fleet, of the processing plants, and of the transportation system. Limitations on the capacity of the industry, and its capability and flexibility, are explored in terms of social, economic and technical aspects. The study is based on interviews with fishermen, buyers, processors and distributors, and on data made available by the National Marine Fisheries Service. Although the fisheries is in a state of expansion and both vessels and plants have a greater capacity than is now being used, the major problems that may restrict expansion in both fishing and processing are quality control, species selection and market development.
