色林错渔业生产的现状与可持续利用的对策   总被引:4,自引:0,他引:4  
色林错裸鲤(Gymnocypris selincuoensis)是藏北色林错湖泊中惟一的一种鱼类。本文介绍了色林错渔业的开发利用情况,并对色林错裸鲤最小捕捞年龄、捕捞强度、最小网目以及最佳年捕捞产量进行了探讨。从可持续发展的角度,我们认为对色林错鱼类资源的利用必须以保证现有湖泊生态系统的稳定为核心,在满足维持一个足够数量及年龄结构的繁殖群体的基础上,以获得最佳持续经济利益为目标。以往强调甚至采用的最大持续产量理论在高原极端环境条件下并不能作为鱼类资源利用的追求目标或确定渔产量的标准,而只能作为对其捕捞强度的参考。总的允许渔获量应当根据最适捕捞死亡率F0.2来确定。本文最后提出了色林错湖泊鱼类资源可持续利用的8条具体措施。  相似文献

Marine bioprocess engineers face a unique challenge for the millennium: designing methods for the sustainable development of known marine resources, as well as inventing a new generation of tools and processes that will enable a greater understanding of the ocean and its resources and lead to the discovery of new bioproducts for the future. The identification and application of novel, marine-derived pharmaceuticals, cosmetics, nutritional supplements, enzymes, and pigments have already been realized. The current and potential market value of these marine bioproducts is substantial. Continued discovery and development of marine resources will depend on a number of factors: identification of new bioproducts, sustainable use of the product, optimization of production, and efficient product recovery. Successfully addressing these challenges will require the integration and collaboration of mutidisciplinary teams of oceanographers, biologists, chemists, and engineers.  相似文献

A growing number of marine fungi are the sources of novel and potentially life-saving bioactive secondary metabolites. Here, we have discussed some of these novel antibacterial, antiviral, antiprotozoal compounds isolated from marine-derived fungi and their possible roles in disease eradication. We have also discussed the future commercial exploitation of these compounds for possible drug development using metabolic engineering and post-genomics approaches.  相似文献

Bioprospecting involves the collection of biological material for screening for commercially exploitable biologically active compounds or attributes, including genetic information. The authors assess the claim that bioprospecting has the potential to act as a sustainable carrot for biodiversity-rich states to conserve marine environments. They analyze the tensions between the international conventions that address bioprospecting in marine areas: the Biodiversity Convention and the Law of the Sea Convention. In particular, they reject any suggestion that there is a legal presumption in favor of coastal states granting access to marine bioprospectors. They argue that the different approaches taken by the marine scientific research provisions of UNCLOS to fundamental research and research with commercial potential is unrealistic because of the difficulties of drawing the distinction in practice. As a result, the danger is that scientific research will get caught in the hard bargaining increasingly associated with bioprospecting. The authors argue that coastal states will derive greater benefit from research collaborations rather than the distant prospect of winning the product royalty lottery.  相似文献

Wide-ranging, indicator-based assessments of large, complex ecosystems are playing an increasing role in guiding environmental policy and management. An example is the EU’s Marine Strategy Framework Directive, which requires Member States to take measures to reach “good environmental status” (GES) in European marine waters. However, formulation of indicator targets consistent with the Directive’s high-level policy goal of sustainable use has proven challenging. We develop a specific, quantitative interpretation of the concepts of GES and sustainable use in terms of indicators and associated targets, by sharply distinguishing between current uses to satisfy current societal needs and preferences, and unknown future uses. We argue that consistent targets to safeguard future uses derive from a requirement that any environmental state indicator should recover within a defined time (e.g. 30 years) to its pressure-free range of variation when all pressures are hypothetically removed. Within these constraints, specific targets for current uses should be set. Routes to implementation of this proposal for indicators of fish-community size structure, population size of selected species, eutrophication, impacts of non-indigenous species, and genetic diversity are discussed. Important policy implications are that (a) indicator target ranges, which may be wider than natural ranges, systematically and rationally derive from our proposal; (b) because relevant state indicators tend to respond slowly, corresponding pressures should also be monitored and assessed; (c) support of current uses and safeguarding of future uses are distinct management goals, they require different types of targets, decision processes, and management philosophies.  相似文献

The biological resources of the oceans have been exploited since ancient human history, mainly by catching fish and harvesting algae. Research on natural products with special emphasis on marine animals and also algae during the last decades of the 20th century has revealed the importance of marine organisms as producers of substances useful for the treatment of human diseases. Though a large number of bioactive substances have been identified, some many years ago, only recently the first drugs from the oceans were approved. Quite astonishingly, the immense diversity of microbes in the marine environments and their almost untouched capacity to produce natural products and therefore the importance of microbes for marine biotechnology was realized on a broad basis by the scientific communities only recently. This has strengthened worldwide research activities dealing with the exploration of marine microorganisms for biotechnological applications, which comprise the production of bioactive compounds for pharmaceutical use, as well as the development of other valuable products, such as enzymes, nutraceuticals and cosmetics. While the focus in these fields was mainly on marine bacteria, also marine fungi now receive growing attention. Although culture-dependent studies continue to provide interesting new chemical structures with biological activities at a high rate and represent highly promising approaches for the search of new drugs, exploration and use of genomic and metagenomic resources are considered to further increase this potential. Many efforts are made for the sustainable exploration of marine microbial resources. Large culture collections specifically of marine bacteria and marine fungi are available. Compound libraries of marine natural products, even of highly purified substances, were established. The expectations into the commercial exploitation of marine microbial resources has given rise to numerous institutions worldwide, basic research facilities as well as companies. In Europe, recent activities have initiated a dynamic development in marine biotechnology, though concentrated efforts on marine natural product research are rare. One of these activities is represented by the Kieler Wirkstoff-Zentrum KiWiZ, which was founded in 2005 in Kiel (Germany).  相似文献

Polyhydroxyalkanoates (PHA) constitute a group of microbial biopolyesters with important ecosystem functions and a high biotechnological potential. During the past decade, the rapid development of new molecular and microscopic techniques resulted in novel insights into the ecology of PHA‐producing bacteria in aquatic and terrestrial microenvironments. Ecosystems showing fluctuating availability of carbon or transient limitation of essential nutrients, e.g. the rhizosphere of plants or estuarine sediments, contain a broad number of various PHA producers. PHA‐producing microorganisms show a widespread phylogenetic diversity and are often characterized by a symbiotic or syntrophic life style. PHA are already produced commercially in large‐scale fermentation. However, they have to compete economically with petrol‐based polymers. Hence, the development of low‐cost production strategies on the basis of diverse renewable materials is a crucial challenge. Ecological knowledge is required for these developments, which links both parts of the review together. The article highlights how a better understanding of the ecology of PHA‐producing microorganisms can lead to a broader application of microbial biopolymers on the basis of sustainable production processes. These processes have to be evaluated by means of life cycle assessment and Cleaner Production studies prior to their industrial implementation.  相似文献
