广阔的南海热带海域拥有得天独厚的岛礁资源与环境优势,具有巨大的开发利用潜力。近年来,在国家"海洋强国"战略的提出与稳步践行的背景之下,加快南海岛礁渔业资源的保护与可持续利用已迫在眉睫。现代海洋牧场是集生境修复、资源养护、休闲渔业和景观生态于一体的渔业生产新业态,真正实现了海洋经济发展和海洋生态环境保护并重,但目前南海热带岛礁海洋牧场建设仍严重滞后。充分利用南海热带岛礁海域的资源与环境优势,发展热带海洋牧场可以有力振兴岛礁经济、保护与合理开发岛礁资源,同时也是维护南海海洋权益、实践"海洋强国"战略的有力举措。本文论述了南海热带岛礁海域开展海洋牧场建设的优势,包括政策优势、自然地理优势、资源优势和产业经济优势等;提出南海热带岛礁海洋牧场的适宜建设模式,主要包括资源养护与增殖型海洋牧场和休闲旅游型海洋牧场;综述了广东、广西和海南省在热带近岸和岛礁海洋牧场建设方面的进展;阐述了热带岛礁牧场建设面临的困难和风险,包括气候与自然灾害、生物敌害、基础设施落后、海域使用权审批严格等问题;基于对问题的分析,提出了相关的对策与建议,包括科学选址、优化设施设计与投放方案、研发敌害应对技术、提升自动化信息化运营管理能力、创新牧场投资与运行模式、加大政府政策支持与扶持力度等,相关建议以期为未来南海热带岛礁海洋牧场建设提供策略支持。 相似文献

评估大长山生态化开发示范区海洋生态服务价值,为生态化开发建设效果评估提供参考依据。示范区2012年投放塔型钢筋混凝土人工鱼礁改造海底环境,2013年初步进行了建设,养殖品种为刺参、皱纹盘鲍等海珍品。参照《海洋生态资本评估技术导则》,对开发示范区2012-2014年供给服务、调节服务、文化服务3组,养殖生产、捕捞生产、氧气生产、气候调节、废弃物处理、休闲娱乐、科研服务等7大类生态服务价值进行评估。示范区建设前的2012年生态服务价值4 178.65万元,示范区建设后2014年生态服务价值5 373.87万元,增加28.60%。2014年生态服务价值中,养殖生产价值5 068.80万元,较2012年增长1 096.30万元、增幅27.60%,刺参生物量较2012年增加83.3 t、增幅43.09%。文化服务中,2012、2013年示范区建设单位并未对海域进行旅游开发,当年旅游收入均为0;在示范区建设酒店后,2014年接待游客近千人次,直接旅游收入达到60.30万元。下一步应进一步完善评估模型,特别是需要获取准确统计数据,以便准确评估示范区的生态价值。 相似文献

- Explorations of the Mediterranean deep sea using remotely operated vehicles have shown that the sea bed hosts rich habitats, supporting high biodiversity. However, there have been only a few studies dealing with the southern part of the basin, leading to limited protection and conservation efforts in this area.
- This study aimed to explore the sea bed off Linosa Island (Sicily Channel, southern Mediterranean Sea), which is considered a ‘sentinel area’ for alien species and global environmental changes owing to its geographic position, thus deserving special attention.
- Remotely operated vehicle surveys, carried out in 2016 and 2017, were analysed to provide the first ecological characterization of benthic assemblages at depths −19 – −384 m around Linosa Island.
- Communities were dominated by three priority habitats, amounting to 39% of the almost 5 km of the sea floor that was surveyed. These are represented in the euphotic zone by Posidonia oceanica meadows and, at greater depth, by newly discovered dense coral forests and extended rhodolith/maërl beds. Sixteen habitat-forming species included in the Red List of the International Union for Conservation of Nature (e.g. gorgonians Eunicella cavolini and Paramuricea clavata, and black corals Antipathella subpinnata and Leiopathes glaberrima) were recorded, as well as individuals of Sargassum sp. at −100 m depth.
- The volcanic island of Linosa represents a small, naturally preserved area, with very limited human pressure, hosting rich marine benthic biodiversity. Given the high species and habitat richness, we recommend its inclusion in the Special Protected Areas of Mediterranean Importance project (United Nations Environment Programme) and suggest a redefinition of the existing marine protected area extension.

Interacting social and ecological processes shape productivity and sustainability of island small‐scale fisheries (SSF). Understanding limits to productivity through historical catches help frame future expectations and management strategies, but SSF are dispersed and unaccounted, so long‐term standardized data are largely absent for such analyses. We analysed 40 years of trade statistics of a SSF product that enter international markets (sea cucumber) from 14 Pacific Island Countries and Territories (PICT) against response variables to test predictors of fishery production: (i) scale, (ii) productivity and (iii) socio‐economics. Combined production in PICT peaked over 20 years ago, driven by exploitation trends in Melanesia that accounted for 90% of all production since 1971. The size of island fisheries (as measured by total exports), and the duration and magnitude of fishery booms were most influenced by ungovernable environmental variables, in particular land area. The large and high islands of Melanesia sustained larger booms over longer periods than atoll nations. We hypothesize that land area is a proxy for land‐based nutrient availability and habitat diversity, and therefore the productivity of the shallow water areas where SSF are operating. PICT need to tailor management based on the intrinsic productivity of shallow inshore habitats: harvests from atoll nations will need to be smaller per unit area than at the high islands. Particularly countries with low productivity fisheries must consider the crucial economic “safety nets” that export SSF make up for dispersed island populations and incorporate them into broader development and island resilience strategies. 相似文献

人工鱼礁建设是指在自然海区营造适宜于水产经济生物生长繁殖的环境,从而吸引野生或人工放养的海洋生物定居,促进水生生态系统健康发展与海洋渔业资源的增殖与养护。青岛崂山湾公益性人工鱼礁区位于崂山湾南部海域,建设周期三年（2012年~2015年）,工程建设采用了混凝土和废旧渔船两类鱼礁体,共建设三处人工鱼礁群,每处人工鱼礁群使用海域200 hm2。项目建设期间需要采取多项安全防治和环保治理措施,后期管理工作也要同步展开。该项目建成后具有显著的生态效益、经济效益和社会效益,并将为修复海洋生态环境和渔业资源、发展生态休闲渔业、实现渔业可持续发展发挥重要的促进作用。 相似文献

中亚包括哈萨克斯坦、吉尔吉斯斯坦、塔吉克斯坦、土库曼斯坦、乌兹别克斯坦五国,是"丝绸之路经济带"的核心区域,内陆渔业资源禀赋雄厚,世界第一大湖里海以及第四大湖咸海均分布在域内。在前苏联时期中亚各国捕捞渔业和水产养殖发展态势良好,随着东欧巨变及前苏联政局陷入动荡直至解体,渔业生产急剧萎缩,至今虽有复苏但尚未能恢复到苏联时期的发展水平。本文主要基于我们前期研究基础以及FAO和世界银行等统计数据,提出对苏联解体后中亚各国渔业崩溃的原因解读,并探讨在"一带一路"框架下,中国和中亚各国可行的渔业合作方式以及重振中亚渔业的策略方法。 相似文献

Correlations between fine‐scale oceanographic features and aggregations of marine mammals are frequently reported, but the physical forces shaping these relationships are rarely explored. We conducted a series of oceanographic observations and remote sensing surveys of an oceanographic feature near Grand Manan Island known to attract marine mammals on flood tides. We tracked drift drogues from cliff‐top with a theodolite and conducted box‐type surveys with an acoustic Doppler current profiler (ADCP) to assess flow patterns within the oceanographic feature. The feature was also visualized with Synthetic Aperture Radar (SAR) scenes. Drift drogues were advected towards a shear line originating near the northern tip of the island and entrained in one or more eddies downstream. ADCP surveys confirmed the presence of the shear line between rapid easterly flow and slower return flow. As the tide progressed, the shear line extended and manifested a single anti‐cyclonic eddy at its distal end. As the flood tide progressed, northerly flow along the eastern shore of the island intensified and deflected the shear line northwards, shedding the eddy at slack high water. SAR images confirmed the presence of the shearline and eddy system, illustrating the evolution of a wake behind the island on flood tides. Profiles of flow direction and acoustic backscatter revealed secondary flows within the wake consistent with models and observations of other wakes. Oceanographic and remote sensing observations confirm that an island wake is generated by tidal flow past Grand Manan Island and provide an ecological context for the predictable aggregations of odontocete and mysticete cetaceans observed foraging within this region. 相似文献
