Pearls have been a valued resource in most cultures that had access to them. A number of historically important pearling grounds were situated in the waters around today's Indonesia. One of these areas, now largely forgotten, was the Segara Anakan lagoon in South Java. In the seventeenth century, Dutch colonists exploited the lagoon's pearls. Afterwards, the lagoon's oysters were locally exploited as a food item until the late 1970s. While the pearl fishery attracted considerable attention in the colonial literature, its disappearance, by contrast, went largely undocumented. Nowadays, the oysters no longer are found in the lagoon as a result of extensive sedimentation processes. Their former existence is only preserved in the memory of local people. This article examines the history and fate of the pearls of Segara Anakan, providing an example of a formerly valued species whose existence simply became forgotten outside the area. 相似文献

Conflicts over oysters intensified along the US mid-Atlantic coast as traditional management of these valuable resources broke down in the late nineteenth century. In response, states founded management agencies, and mapping oysters was one of their first activities. Virginia and Maryland's first cartographers favored privatizing common property, an alteration that would have displaced thousands of oystermen and benefited wealthier segments of the industry. Cartographers sought to use maps to expand privatization; however, Chesapeake Bay oystermen were numerous enough to wield political influence, and they rejected one of the first major surveys and shaped the production of the other two, using them to protect their common property while making these rights visible to the State. Many conservation practices in the eastern USA grew out of local people's traditions, and this study explores the role of the mapping process amid the broader context of a shift in the scale of management to state agencies. 相似文献

Quilty, P.G., Clark, N. & Hibberd, T., 21.01.2015. Crenostrea sp. cf. C. cannoni (Marwick, 1928) (Bivalvia: Ostreacea) and associated fauna from east of Heard Island, Kerguelen Plateau: age and palaeoenvironmental value. Alcheringa 39, xxx–xxx. ISSN 0311-5518A well-preserved single left valve of a large oyster embedded in coarse volcaniclastic sediment and identified as Crenostrea sp. cf. C. cannoni (Marwick, 1928) was dredged from east of Heard Island, central southern Indian Ocean. It is accompanied by a fragment of the pectinid bivalve Austrochlamys sp. indet. and foraminifera. Austrochlamys sp. indet. and other bivalve fragments were analysed for 87Sr/86Sr, δ18O and δ13C, the results yielding an age of 17.5 Ma (later early Miocene) and a water temperature of ca 10°C. Foraminifera and sediment characteristics indicate that accumulation occurred in mid-continental shelf depths, at a location where nutrient supply was good.Patrick G.

Abstract: Taking a political ecology approach, this paper offers a critical evaluation of conservation efforts undertaken in Gambia's Tanbi Wetland National Park (TWNP), a “wetland of international importance” as designated by the Ramsar Convention. Focusing on the oyster commercialization component of the World Wildlife Fund's Gambia–Senegal Sustainable Fisheries Program (GSFP) in the TWNP mangrove forests, we identify oystering practices that promote mangrove conservation and others that conflict with sustainable management. The project, which aims to commercialize oyster culture through local women, is entirely production oriented, ignoring the ways in which oysters are prepared for market. As a result, degradation of the very mangrove forests the GSFP aims to conserve may be accelerated. The project selectively engages with local environmental knowledge and fails to consider the implications of expanding the value chains for oysters and their shells. Unless the World Wildlife Fund addresses these issues, its conservation objectives and potential socioeconomic benefits may be compromised. 相似文献
