农业部调整长江流域禁渔期制度 总被引:1,自引:0,他引:1
《中国水产》2016,(2):4-4
正本刊讯(李明爽报道)日前,农业部发布通告,对长江流域禁渔期制度进行调整。新的长江流域禁渔期制度自2016年1月1日起开始实施。近年来,长江流域经济社会快速发展,水域生态环境发生了剧烈变化,水生生物资源持续衰退,资源环境专家、渔业管理部门、渔民和社会各界要求进一步延长禁渔期时间、完善禁渔期制度的呼声日益强烈。为进一步贯彻落实党中央国务院《关于加快推进生态文明建设的意见》,更好地养护水生 相似文献

前言。当前世界许多国家发展内陆水域渔业仅局限于自然渔业资源的开发,从而使全球内陆水域捕捞渔业产量一直处于较低的水平。目前世界各国渔业资源所受的各种压力日益增加,水生生物栖息环境的不断恶化,以及对加强渔业管理力度不大等各种不利因素,结果使内陆水域捕捞渔业产量每况愈下。虽然有些国家采取诸如限制网目大小,实行禁渔区和禁渔期等一系列传统性的渔业管理措施,在某种程度上可能对渔业资源保护有所改善,但是这些措施在执行时遇到不少的困难和障碍。在这种情况下,渔业工作者不得不考虑采取其他的技术措施,其中包括有。 相似文献

A cointegration analysis is conducted to examine the effect of fishery subsidies on fisheries production using data compiled
over more than 30 years in Japan. The results illustrate that one fishery production indicator (production value per fishermen)
shows a positive relationship with one particular group of government financial transfer (GFT) (that is, government general
service expenditures including cost for fishery managements, scientific researches, and other administrative activities).
No other tested results between GFTs and fishery indicators showed a real relationship. Although further scrutiny is awaited,
this study could provide an empirical basis for an argument that, under an effective fishing management system, fisheries
subsidies do not necessarily cause production increases or negative impact on fishing stocks. 相似文献

This paper discusses the role of fishing communities in the stewardship of their adjacent fish resources, and the benefits associated with community participation in co‐management. Contrary to the view of most fisheries management agencies, local communities are able to design institutions that can successfully restore equity and limit access to the fishery. The dismissal of local concerns may be at the root of biological and social crises in fisheries, and the privatization of common fishing rights world‐wide through individual transferable quotas (ITQs) is contributing to these problems. Community involvement that is embedded into a network of management at larger spatial scales would allow fishing communities to regain some control over their livelihoods. Meaningful co‐management arrangements must go beyond consultation by redirecting the flow of social and economic benefits from the fishery back into communities. Unless geographically defined communities are allowed to share power and responsibility with government fisheries managers, both fish stocks and fishing as a way of life are in danger of vanishing. 相似文献

渔业船员人为因素是导致渔业船舶海上事故的主要原因,渔业船员管理工作直接影响着海洋渔业安全生产。新形势下,传统静态渔业船员管理已无法适应科学发展的客观需要。将射频卡(非接触式IC卡)应用于渔业船员证书中,实现船员信息一卡制和渔业船员动态跟踪管理,提高渔业船员管理的水平。 相似文献

延长拖网伏季休渔期的渔业资源养护效应 总被引:1,自引:1,他引:0
海洋伏季休渔制度是当前中国最主要的渔业资源管理制度之一,并在实践中得到不断调整与完善,新的海洋伏季休渔制度已于2017年发布实施。为论证新制度延长拖网休渔期的渔业资源养护效应,本研究依据2015—2017年每年5月东海区拖网大面定点调查资料,利用Ricker动态综合模型,从拖网的渔获结构特征和带鱼(Trichiurus japonicus)的种群动力学过程视角开展了相应的量化分析研究。研究结果表明, 5月拖网利用主体为带鱼和小黄鱼(Larimichthys polyactis),带鱼和小黄鱼的性成熟比例分别为92.04%~95.57%和13.82%~29.55%,幼鱼比例分别为74.94%~88.90%和0.03%~4.19%;带鱼种群经过4.5个月的休渔,其单位补充量资源量、单位补充量渔获量和平均渔获质量与3.5个月休渔期相比较,分别增加了7.04%、8.96%和20.78%。以上结果表明,提前并延长拖网休渔期,东、黄海主要经济渔业资源带鱼与小黄鱼的产卵群体和幼鱼得到进一步保护,资源增殖效果随着休渔期的不断延长而增加,新制度的休渔时间设置更趋合理。但由于开捕后的带鱼与小黄鱼渔获仍主要以当龄鱼为主,有必要同时配套执行现已颁布的最小网目尺寸和开捕标准等其他渔业资源管理措施,以确保伏季休渔制度主导下的渔业资源养护效果能真正得到巩固,渔业资源的种群结构能够得到切实好转与不断合理化。 相似文献

改革开放以来,随着渔业经济的快速发展,我国的渔业发展面一临着渔业资源严重枯竭、渔业监管困难、渔民收入增长幅度放缓等诸多问题。为此学术界在渔业资源管理方法上提出了许多意见,同时也存在着一些分歧。文章通过理论推演,结合文献数据,探讨了渔村社区组织与我国渔业协会的关系,分析了包括渔业协会在内的渔村社区组织对渔业资源管理的作用,通过对代表性渔业资源管理理论的利弊分析,剖析了渔民协会等渔村社区组织的渔业资源管理职能。同时指出由于渔业协会在资源管理中具有重要作用,但因其自身也存在着一定局限性,因此,培育渔业协会、完善其资源管理职能,实行基于渔业协会等渔村社区组织的合作管理也就成为我国加强渔业资源管理的一种制度选择。 相似文献

An important element in the U.S. management of fisheries in the North Pacific is the existence of Community Development Quotas (CDQs) which grant community corporations the right to fish in many fisheries off the coast of Alaska. The eastern Bering Sea pollock fishery is the largest of these fisheries, with 10 % of the quota allocated to CDQs. The CDQ program evolved from a partial catch share program that existed from 1992 to 1999 within a limited-entry fishery to a full catch share program with separate spatial rights. In this paper I examine the temporal and spatial uses of CDQ rights and how these uses have changed since the implementation of catch shares throughout the fishery. I also discuss the dispersion of CDQ royalties since the program’s inception and examine the prices of CDQ fishing rights from 1992 to 2005 when data on quota value were reported to the government. I compare quota prices to information about walleye pollock fishing and examine the evolving use of CDQ rights. The use of the CDQ right has changed from extending the season to enabling fishing in otherwise closed areas during the season. The number of vessels fishing with CDQ rights has declined substantially, with all pollock CDQ fishing now done by at-sea processors. 相似文献

Malaysian fisheries employ multiple measures to improve management; however, not all are well-suited to the multispecies fisheries. As part of a pilot project, an individual quota system was introduced for the purse-seine fishery off the East Coast of Peninsular Malaysia (ECPM), but no assessment of this particular measure nor the feasibly of its implementation has been confirmed. Therefore, this study analysed spatial and temporal patterns of purse-seine fishing, by collecting catch composition data per landing and its fishing ground within three period fishery surveys between August 2017 and September 2018 at six different landing sites. Similarity and cluster analysis examined species composition and diversity to determine the feasibility of implementing a single-species quota system in this multispecies fishery. Some overlapped of indices results and minor difference in catch composition were found due to changes in spatial and temporal fishing activities. However, no specific spatial or temporal patterns were discernible as structuring the fishing grounds used by purse-seiners. The absence of patterns, using the available data, might be attributable to huge species aggregations and widely distributed and homogenously mixed fish stocks. Thus, it is likely impractical to manage species individually in such a multispecies fishery. 相似文献
