Recreational fishing, otherwise known as angling, is both a significant resource use and a leisure activity in Australia. It has not received much scientific or policy attention, having been perceived as unimportant relative to commercial fishing and characterised by poor social, biological and economic data. Attention is increasing, however, as the ecological, economic and social significance of the activity is realised. The article briefly reviews recreational fishing and discusses the reasons why the activity has traditionally been ignored by policy-makers and researchers. Current policy issues are identified, and a generalised framework suggested for policy and research.  相似文献

This paper describes the hitherto unreported occurrence of mid‐Holocene mangrove deposits in the Richmond River estuary, southeastern Australia, thereby providing evidence for changes in the distribution and composition of mangrove communities within a subtropical estuarine system during the Holocene. Stratigraphic, radiocarbon and palynological evidence indicates that widespread development of mangrove communities took place in the upstream reaches of the Richmond River estuary during the period 7000 to 6000 years BP. These communities maintained their habitat through substrate aggradation under the conditions of a moderate sea‐level rise, in contrast to other estuaries within the region, which generally experienced the submergence of intertidal substrates. Mangrove species belonging to the family Rhizophoraceae, most likely Bruguiera gymnorrhiza and Rhizophora stylosa, dominated these communities, in strong contrast to contemporary communities, which are dominated by Avicennia marina. Moreover, these mid‐Holocene communities were located a considerable distance upstream of the contemporary occurrences of Rhizophoraceae species within the estuary. The changes in the spatial distribution and composition of mangrove communities parallel the large‐scale evolution of the estuary driven by sea‐level variation. Shallow, buried Pleistocene terraces probably contributed to the regionally unique aggradational response of the mangrove communities and their substrates to a sea‐level rise during mid‐Holocene times.  相似文献

The relationships between traditional Aboriginal land owners and other Park users in Kakadu National Park in the Northern Territory are characterised by competing agendas and competing ideas about appropriate ways of relating to the environment. Similarly, the management of recreational fishing in the Park is permeated by the tensions and opposition of contested ideas and perspectives from non‐Aboriginal fishers and Aboriginal traditional owners. The local know‐ledge and rights of ‘Territorians’[non‐Aboriginal Northern Territory residents] are continually pitted against the local knowledge and rights of Aboriginal traditional owners. Under these circumstances, debates between non‐Aboriginal fishers and Aboriginal traditional owners are overwhelmingly dominated by the unequal power relationships created through an alliance between science and the State. The complex and multi‐dimensional nature of Aboriginal traditional owners’ concerns for country renders these concerns invisible or incomprehensible to government, science and non‐Aboriginal fishers who are each guided by very different epistemic commitments. It is a state of affairs that leaves the situated knowledge of Aboriginal traditional owners with a limited authority in the non‐Aboriginal domain and detracts from their ability to manage and care for their homelands.

Indian trawl fishers in the Palk Bay regularly engage in cross‐border fishing to the detriment of Sri Lankan artisanal fishers whose nets are irreparably damaged. Increasing tension between Indian trawl fishers from the state of Tamil Nadu and Sri Lankan artisanal fishers from the Northern Province has resulted in the Sri Lankan government patrolling the international maritime boundary line (IMBL) more stringently and increased arrests of Indian trawl fishers. This paper argues that the present “fisheries crisis” in the Palk Bay must be understood from a political ecology perspective that takes cognizance of the circuitous nature of capital accumulation and how fisher conflict, ethnicity and the politics of the nation‐state have shaped the spatial practices of accumulation. In a changing global context where semi‐industrial vessels are increasingly crossing boundaries, it argues for more context specific studies of processes of capital accumulation.  相似文献

Shipwrecks are becoming increasingly popular and, therefore important attractions for recreational scuba divers. Divers’ usage of these sites has the potential to create a range of adverse impacts on their cultural heritage values. Impacts associated with recreational scuba diving include boat anchor and mooring damage, impairment of site integrity and stability, the effects of intentional and unintentional contact with shipwrecks and artifacts, as well as divers’ exhaled air bubbles coming into contact with shipwrecks. While these consequences may not present a major threat in comparison to other human impacts, such as fishing activities, extractive industries or commercial salvage, their cumulative effect can be significant, particularly at sites where visitation levels are high. Unlike natural events such as storms, diver impacts can be controlled and managing these impacts is an important component of a heritage management strategy for any site. Heritage managers face the difficult challenge of, on the one hand, balancing divers’ access to important underwater cultural heritage sites, and on the other hand, protecting these sites. This paper outlines the causes and nature of potential recreational diver impacts on shipwrecks, briefly describing a range of management approaches that can mitigate such impacts, and presents a framework for the management of diver impacts on cultural heritage values of historic shipwrecks. The framework is designed to assist managers in deciding on appropriate management actions and priorities for particular sites.  相似文献

This article tests capture theory by analyzing voting behavior on U.S. Regional Fishery Management Councils. Some seats on the councils are reserved for state and federal agency representatives; others, for political appointees. The political appointees primarily represent special interests (specifically, commercial and recreational fishing interests); a smaller number of appointees represent public interests. We use logistic regression to model the vote of state and federal agency representatives on the councils as a function of the votes of commercial interests, recreational interests, and public interests. We find evidence that some state agencies are captured by special interests from their states, but not systematic evidence across all states. We find that state agency representatives voted with commercial interests from their own state in five of the sixteen states in our sample; with recreational interests in three states; and with both special interests in two states. These ten states support the capture hypothesis; the other six states do not. We find no evidence that federal agencies were captured on the councils. We conclude that the gubernatorial‐driven appointment process leads to capture at the state level by promoting voting blocs among state agency representatives and special interests from those states. Federal agency representatives, by contrast, are better able to maintain their distance from state‐level politics on the councils, and thereby enhance their ability to vote independently on fishery management measures.  相似文献

Abstract

The Tweed Fisheries Acts of 1857 and 1859 were victories for upstream landowners over coastal and estuarine commercial fishermen. In the manner of the Game Laws, these class-based Acts placed the interests of leisured, sport-fishing anglers above those of the net-fishing communities at the mouth. The latter were severely disadvantaged, and the fishermen and their families often clashed with the River Tweed Commission's bailiffs and local police who tried to enforce the Acts' restrictive terms. In particular, the contraction of the autumn netting season to allow more fish into the upstream reaches had converted legal fishing into poaching and was met with open defiance. The inability of the Commissioners to prevent mass disobedience or provide enough bailiffs to enforce the law prompted a request to the Home Secretary for assistance, with a suggestion that the Admiralty supply a gunboat to protect the bailiffs and overcome the protests. HMS Ruby was despatched to Berwick in October 1861 for the close season, and a succession of gunboats followed over the next twenty years in an unprecedented deployment of naval force to support the civil authorities.  相似文献

This study examines the potential socio-spatial impacts of a new series of marine protected areas (MPAs) on fishers in Moorea, French Polynesia. The establishment of the MPAs is contextualized within recent and historical processes of economic development and theories of women in development and gender, culture and development. Seventy adults from three neighborhoods in Moorea were interviewed. Analysis of the data provides new information about the characteristics of fishing in Moorea. Unlike most fishing cultures and communities throughout the Pacific Islands, men and women in Moorea have similar, as opposed to segregated, spatial patterns of fishing activities and fishing methods. The study also points out the potential negative impacts of the MPAs on both men and women, particularly younger and lower-income fishers.  相似文献

Resistance to British control of Ireland’s maritime landscape under the United Kingdom of Great Britain and Ireland (1800–1922) was highly localized, enacted in part through Irish choices in boat construction and patterns of movement at sea. British naval authorities overseeing Achill Island in County Mayo used both coercive and conciliatory means to replace Irish subsistence fishing from regional vernacular boats with commercial fishing from larger non-local vessels reliant upon piers and dredged harbors. These changes encouraged islanders’ dependency upon imported food and wage-based employment performed under Protestant surveillance. Indigenous boats including curraghs and yawls played central roles in Irish resistance to these changes, through the assertion of traditional lifeways and practices.  相似文献

Critical global political ecology and critical cultural political economy approaches are used in a study involving decades of research to evaluate the changing relationship between fisher livelihoods, seashore tourism, and urban industrial development in an economically dynamic region of coastal Brazil. As the metropolitan area of Rio de Janeiro expanded and encompassed fishing communities, socio‐environmental transformations created threats to fisher ways of life, opened new multi‐functional opportunities, and also introduced unrelated juxtaposed activities. As stocks fell due to overfishing and urban industrial pollution over the last two decades, small‐scale inshore fishing declined in the bay–lagoon systems located to the east and south‐west of Rio de Janeiro. Tourism increased but proved to be a poor substitute for declining fishing activities because it and other new multi‐functional activities rarely aggregated significant value to local livelihoods. Consequently, only a small minority of fishers benefited and remained on the islands and sand spits, while the great majority left for the mainland. New cultural and environmental functions were also absent, so that of the types of multi‐functionality identified by Wilson and Holmes, those present in the study area are weak and basically serve outside urban production and consumption interests.  相似文献

Crop harvests, livestock and poultry products, and hunting and fishing activities provide the themes for 18 annual festivals staged by rural South Carolina communities on weekends and holidays during the April-December festival season. Drawing 5,000 to 25,000 participants, the typical harvest festival mixes the promotion of visitor industry with the friendly spirit of a community gathering. Urbanites are attending South Carolina's harvest festivals in large and growing numbers. They are attracted by their ready accessibility, novelty and emphasis on something-for-everbody family fun with a distinctive "down home" country flavor. For the sponsoring communities, the festivals provide not only an excuse to get together and have fun, but also a morale boost and an important source of funds for much-needed civic projects. In the years to come it is likely that the state's harvest festivals will increase in number, and that the attendant rise in competition will on the one hand lead to improvements in management and on the other increase the incidence of gimmickry designed to boost attendance.  相似文献

Marine fish bones are abundant components of human food remains at prehistoric sites in the eastern Tropical Pacific. Their quantification and interpretation in terms of human procurement strategies have been hampered by the use of large-meshed sieves and by the obstacles presented to faunal experts by fish taxonomic diversity. Since many important food fish families are speciose, this paper emphasizes the importance of species-level identifications. Making extensive use of Spanish-language articles on fish distribution and ecology, and the commercial and artisanal fisheries literature, it identifies groups of nearshore and littoral fish species that show greater and lesser tolerance for hard substrates (reefs and rocks), estuaries and coastal lagoons, and deeper clearer waters farther offshore. Most of the regional archaeological sites were located near estuarine habitats. The drab-colored fish they attract are generally poorly known. Hence, a particularly detailed analysis is offered of fish behavior within low salinity coastal inlets. Fourteen archaeofaunal fish samples from Costa Rica, Panama, and Ecuador are evaluated in the light of the environmental information generated by the biological and fisheries surveys. It is concluded that most sites have a broadly estuarine orientation and that the input of hard substrates is everywhere <10%. Two sites, Salango, in Ecuador, and Vidor, in Costa Rica, exploited epipelagic fish that swim in large shoals and deep water demersal predators. Sites situated more than 10 km from the coast exploited a wide variety of marine fish. In Parita Bay, Panama, a comparison of fish faunas from Cerro Mangote (6000 B.P.) and Sitio Sierra (1800 B.P.) elicits the hypothesis that regional fishing strategies shifted between these dates from a shore-based, netless strategy to a more complex one that incorporated fine-meshed gill-nets and watercraft.  相似文献

Socio‐cultural and ecological literature about Australian Indigenous groups reveal that fishing is a vital part of everyday life for many groups who have customary and recreational fresh and salt‐water affiliations. This vitality exists and has meaning for families and communities in the Kimberley's Fitzroy Valley region of Northern Aboriginal Australia. Less well known, however, is the central part that fishing plays in jaminyjarti, a ritual that relies on close kin regularly catching, cooking and sharing fish for bereaved family members during the ‘sorry business’ time that emerges after the death of a loved one. What becomes evident is that while fishing is undoubtedly intertwined in the everydayness and sociality of life, it is also central to comforting the bereaved during and after the grieving process that accompanies death.  相似文献

Large wild areas are important for both nature conservation and nature-based recreation. Information on the reciprocal relationships between recreators and the environments in which they recreate can help both conservation and recreation management. We considered motivations, perceptions, environmental concerns, and social concerns among flyfishers who recreate within the Tasmanian Wilderness World Heritage Area on the Central Plateau of Tasmania, Australia. Using semi-structured interviews with 27 participants, we established that they were motivated by a love of nature, desire for experience, escapism, connection, and challenge. On the basis of motivations and attitudes, we discriminated four groups of flyfishers: “social” (those who fish with friends), “trophy” (lone fishers who are goal-oriented), “outdoor enthusiast” (those who enjoy the outdoor experience, fishing optional), and “hunter-gatherer” (those prepared to travel long distances for catch). Nonetheless, all groups perceived environmental and social problems related to fishing and visitation behaviours, from littering to climate change. Fishers perceived environmental problems included identifying exotic weeds and pests but did not specifically include trout as a pest, despite their exotic status and adverse effects on native ecosystems. However, flyfishers were aware of most of their impacts and were willing to help mitigate them. Such insight is significant for geographers and those in associated disciplines and professions seeking to manage wild protected areas.  相似文献

Commercial red snapper fishing dominated the Pensacola, Florida, waterfront around the turn of the 20th century. At the height of the industry, nearly 50 large schooners sailed from Pensacola, supplying demands for fresh fish across the United States. Using historical data from the List of Merchant Vessels of the United States and archaeological data from three probable commercial red snapper fishing schooner shipwrecks in north‐west Florida, this article traces build trends and characteristics among industry vessels from 1881–1930. Recognizing these developments may help identify other commercial red snapper fishing vessels among Gulf of Mexico‐area archaeological shipwreck sites.  相似文献

A method is suggested whereby modern ecological information on fish behaviour and distribution, together with commercial catch figures, may be used to assess season of occupation of archaeological sites. Monthly catch probabilities for each species are scaled by minimum numbers from prehistoric osteological assemblages to yield an overall likelihood of the fish being caught at different months of the year. A test case on two assemblages from Palliser Bay, New Zealand, suggested year-round habitation, and this was consistent with individual qualitative seasonal markers. The fishbone evidence can also be used to comment on aspects of prehistoric technology connected with marine foods, such as the use of canoes, baited traps, long line hauling, rock fishing and seine netting. In addition, the fish information substantiated subtle environmental changes which are believed to have taken place in this region.  相似文献
