    Description: Natural potential of the increase in abundance is identified for artemia populations, based on the analysis of «inherent rate of natural increase in abundance» (r) change. It can be considered as the quantitative assessment of the pressure degree of natural factors on artemia populations. As an example of increase in population abundance, the data are presented that were obtained for A. salina populations in 8 saline lakes of Crimea (Russian Federation). Based on the study of seasonal dynamics of artemia population abundance in the lakes, the values (r) were estimated for different time spans during the growing season. Calculations for r values for the total growing season of the populations showed that the total ratio between mortality and birthrate is negative for all lakes. It can be assumed that maximum rate of increase in abundance of natural artemia populations is determined by the ratio of their definitive weight and average weight of an individual in a population. The analysis indicated that average weight of an individual in a population of A. salina in various water bodies and in different years varied from 0.23 to 0.53 g, i.e. changed in 2.5 times. Under extreme values of Wav/Wmax, the rmp appears to be equal to 0.0187 and 0.0046, respectively. Upon comparison of two extreme options, it can be noted that the increase of Wav/Wmax in 2.5 times leads to the decrease of rmp in 4 times.
    Description: На основе анализа изменения «врожденной скорости естественного увеличения численности» (r) изучено, в какой мере в популяциях артемии реализуются природные потенции увеличения их численности. Ее можно рассматривать как количественную оценку степени давления природных факторов на популяции артемий. В качестве примера роста численности популяции были приведены данные, полученные П.М. Вороновым для популяций A. salina в 8 соленых озерах Крыма. На основе изучения сезонной динамики численности популяций артемий в озерах были рассчитаны значения (r) для отдельных отрезков времени в течение вегетационного сезона. Расчеты значений r для всего вегетационного периода популяций показали, что во всех озерах суммарное соотношение между смертностью и рождаемостью имеет отрицательный знак. Можно допустить, что максимальная скорость увеличения численности в природных популяциях артемий определяется соотношением их дефинитивного веса и средним весом особей в популяции. Анализ показал, что средний вес особи в популяции A. salina в разных водоемах и в разные годы колеблется от 0,23 до 0,53 г, т. е. изменялся в 2,5 раза. При крайних значениях Wср/Wmax величина rmp оказывается равной, соответственно, 0, 0187 и 0,0046. Сравнивая два крайних варианта, можно отметить, что при увеличении Wср/Wmax в 2,5 раза это приводит к уменьшению rmp в 4 раза.

    Description: This description of the small-scale sector of the Southern New England (Massachusetts, Rhode Island and Connecticut) fishery includes information on the fishermen (their ages, education, experience, occupational training, family involvement and reasons for fishing) and the physical characteristics of the fleet (the boats and gear). Fishing patterns are analyzed by species, geographical areas and seasons. The economic structure of small-scale fishing is described in terms of investment, net and gross earnings, fuel costs, crew payments systems and marketing arrangements. Management implications of this information and analyses are included.

    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.
    Description: This document is the final report for NOAA Contract #03-6-043-35165, which supported most of the research. Research was also supported with funds from the Pew Memorial Trust and from the Department of Commerce, NOAA Office of Sea Grant under Grant #04-8-M01-149, and was sponsored by the Woods Hole Oceanographic Institution's Marine Policy and Ocean Management Program.

    Description: Development of shrimp-export industry brought about the underdevelopment of Pacific Mexico's inshore fisheries. The rural fishery of south Sinaloa provides a case in point, as well as a point of departure for considering fisheries development and management policy for similar fisheries in certain other less developed countries.

    Description: Despite an absence of freshwater exploitation, the adult salmon run in the Matamek River, Quebec, declined during 1975-1980 to 〈23% of the level thought to occur there prior to 1967. Returns in 1979 and 1980 of adults tagged as smolts were 1.0% and 0.9%, respectively. Numbers of emigrating smolts and their corresponding adult returns are not significantly correlated, although we observed a trend towards more salmon (2 sea year fish) returning with larger numbers of migrating smolts. Since 1967 there is noted a decrease in the age at which returning adults smolted and females appear to now constitute a larger percentage of returning grilse and salmon. These, and other changes in life history characteristics, appear to be caused solely by commercial exploitation.

    Description: This report represents a first step at considering the potential for the use of market-based incentives to aid in the resolution of fishery bycatch problems. Market-based incentives have several advantages over more traditional command-and-control approaches, including cost-effective allocations of environmental controls; incentives for firms to seek technological solutions; flexibility; returns to the public for the use of its resources; and lower administrative costs in some cases. Notwithstanding these advantages and with several notable exceptions, market-based incentives are almost never employed in the management of fishery bycatch problems. There may be several reasons why this is the case, including significant distributional effects, high costs of monitoring and enforcement, difficulties in educating consumers about product attributes, administrative and transactions costs, or merely oversight. We consider this report to be an "advanced outline" of the issues surrounding the consideration of market-based incentives. We begin first by developing in Section 2 a definition of bycatch, including a "typology" of bycatch types. Next, we compile available public information on bycatch in U.S. fisheries, as defined by target species, location, and gear type (Section 3 and Appendix 1). We then review, in Section 4, two potentially relevant strands of literature, the economic theory of multispecies fisheries and studies from other social sciences of how small-scale fisheries deal with problems of bycatch. In Section 5, we describe, in general, the kinds of market-based policy instruments that may be of use in managing bycatch problems. Following this evaluation, we identify and discuss, as case studies; three priority fisheries: th~ northeastern groundfish fishery; the Gulf of Mexico shrimp fishery; and the eastern tropical Pacific yellowfin tuna fishery (Section 6). Finally, in Section 7, we outline approaches to identifying appropriate policy instruments, including a qualitative comparison of market-based approaches, an examination of the effect of specific types of uncertainty on the choice between taxes and ITQs, and the development of a "proposal" for a bycatch management "policy package." This section concludes with a proposal for a set of priority market-based approaches to bycatch management in the three cases discussed in Section 6.

    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.
