| 1 | The impacts of suspended mariculture on coastal zones in China and the scope for Integrated Multi-Trophic Aquaculture显示文摘Introduction:China is responsible for more than 60%of global aquaculture production.As the frontiers of food production have expanded,the cultivation of marine organisms in coastal zones and the open ocean has grown rapidly.The dominant mariculture industry in China is suspended mariculture,which uses net cages,ropes,or other structures suspended in the water column to cultivate aquatic organisms.This systematic,quantitative review provides a clear and comprehensive account of research that has investigated the adverse impacts of suspended mariculture in China and reviews research that has applied Integrated Multi-Trophic Aquaculture(IMTA)systems for mitigating impacts.This work builds on 218 peer reviewed papers that have been published in English-language journals.Outcomes:Eighteen impacts were identified,including chemical,ecological,physical,and socioeconomic impacts.Eighteen measures for improving suspended mariculture were recommended consisting of government department,farm management,and ecological engineering measures.IMTA was the most frequently recommended measure.The capabil-ities of IMTA for bioremediation and increased farm production were the most frequently studied advantages.Seven other benefits have been explored but remain understudied.The current challenges facing the expansion of commercial IMTA include limited use of new technology,limited skills development,decreasing production of low trophic-level species,biogeographic and temporal barriers,and negative system feedbacks.Conclusion:Despite challenges,implementing commercial IMTA is a promising measure for reducing the impacts of sus pended mariculture because it presents a range of secondary benefits that can improve the overall sustainability of aquaculture in the coastal zone. | Reece Wartenberg Limin Feng Jia Jun Wu Yim Ling Mak Leo L.Chan Trevor C.Telfer Paul K.S.Lamab.c | 2017 | Ecosystem Health and Sustainability2017，3，6： | 0 |
| 2 | 可持续水产养殖理论与方法探讨显示文摘水产养殖是农业的重要组成部分,是全球农业发展的主要力量。每年该行业都会有许多最新的技术与理论应用到实践生产中。养殖业的重要性不言而喻,该产业对环境的影响也引起了的广泛关注,目前有一些新颖的环境友好的科学养殖理论与体系较为流行,如鱼菜共生体系,虾瓜轮种体系,生态水文学理论,多营养级综合养殖系统等,这些养殖理论来自于实践,围绕着"资源利用最佳化、环境影响最小化、经济效益最大化"开展与完善, | 徐永健 瞿方 | 2016 | 水产养殖2016，37，3： | 0 |
| 3 | 基于卷积神经网络和数据融合的筏式养殖区提取显示文摘准确提取海水筏式养殖区信息对于海洋资源管理和环境监测具有重要意义,但是筏式养殖区养殖筏因淹没于水中常出现数据弱信号区域的现象,导致仅凭光学影像提取精度较低。因此,本文以威海荣成湾为研究区域,通过添加通道注意力机制改进U-Net神经网络并结合高分2号光学影像光谱信息以及高分3号雷达影像纹理信息,尝试提高筏式养殖区提取精度。结果表明:(1)无论是对于单一的光学影像还是光学和雷达影像融合影像,添加通道注意力机制的U-Net神经网络预测结果总体精度都会提高,提高幅度在2.21%~4.12%之间。(2)利用改进后的U-Net神经网络处理融合数据,总体精度达到95.75%,相对于仅用高分2号影像的精度高4.3%;(3)对于弱信号区域,利用改进网络以及融合数据提取的总体精度和Kappa系数分别为91.61%和0.8277。该方法可以对海洋筏式养殖区弱信号区域进行有效提取,能够为海洋养殖面积统计以及海洋环境检测提供技术支持。 | 李龙坤 蔡玉林 徐慧宇 刘照磊 王思超 高洪振 | 2023 | 海洋学报2023，45，8： | 0 |
