稻鱼共生生态系统中物质循环及经济效益

稻田养鱼鱼养稻、稻谷增产鱼丰收的稻鱼共生结构(Rice Fish Mutualism)反映了稻鱼共生生态系统中的物质就地进行良性循环和能量朝着稻、鱼双方有利的方向流动，产生了较高的经济效益。     

稻田夏花养鱼种技术

稻田养鱼,以稻为主,稻鱼兼作,充分挖掘稻田的生产潜力,以鱼促稻,稻鱼双收。随着稻田养鱼的发展,它在水产养殖业中的地位越来越重要 1、发展稻田养鱼的意义 1.1增肥保肥作用。鱼类排出的粪便施于田面,为水稻提供了大量的有机肥。     

浅析稻渔立体种养技术应用与发展

稻渔立体种养在我国应用时间久,此种种养方式是种植业与养殖业的相互促进,有利于提高土地利用率,增加鱼、虾、蟹等水产品产量,从而提高种养殖综合经济效益,实现生态与经济的相互促进,对推进农业绿色、高效、循环发展起到了重要作用.一田多用、一季多收的稻鱼立体种养在天津市宝坻区已然深耕多年,现今已初步实现稻鱼双丰收的目标,但是由于地区差异,品种不同以及技术不到位等诸多问题,稻鱼立体种养仍有诸多弊端,本文就此浅析稻鱼立体种养技术应用与发展.     

垄稻沟鱼丰产技术探索

垄稻沟鱼是近年来发展起来的一种先进的稻田养鱼模式。它能克服传统稻田养鱼中稻鱼之间不协调的矛盾，达到了“水稻养鱼鱼养稻，稻谷增产鱼增收”的目的，因此受到了广泛的重视，日前各地正在大力推广这一种养新技术。为了进一步探索垄稻沟鱼的丰产技术，     

黔东南州推广“垄稻沟鱼”

贵州黔东南苗族侗族自治州今年在全州16个县推广稻田养鱼“垄稻沟鱼”新技术,87个点总面积达10,319亩。为大面积推广“垄稻沟鱼”新技术,州组织了36人到四川进行“垄稻沟鱼”技术考察,州、县政府共拨出专款10余万元,由水产、土肥、农业推广等部门抽出83人到基层蹲点,各区、乡、村举办了“垄稻沟鱼”技术     

稻鱼互利的机理

稻田养鱼在我国历史悠久，历史记载始于汉末三国时期。近年科学家创立了“稻鱼互利”理论。其核心内容是：“稻鱼协同，以废补缺，共同互利”，建立新的生态系统，促进物质就地循环，使能量转向有利于稻鱼双方转化，从而达到稻谷增产鱼丰收。     

浙江丽水青田稻鱼综合养殖技术备受国内媒体关注

2012年7月中旬,在全国水产技术推广站副站长李可心的带领下,国家、省、市等多家平面媒体对青田稻鱼综合种养技术进行了采访调研。目前,青田稻田养鱼面积达8万多亩,产量1450万t。据悉,此次采访团走访了德清、绍兴、景宁等同样具有稻鱼种养模式的县市,与其他地方相比,青田的稻鱼种养有着独特的优势。李可心认为,青田的稻鱼共生系统是建立在自然生态的基础之上的,在促进农业增效和农民增收,推动稻鱼养殖转型升级中,完全实现了"百斤鱼、千斤粮、万元钱"     

专家聚会研讨稻鱼结合生产问题

10月中旬中国农业科学院和中国水产科学院召开了稻—鱼结合学术讨论会。来自作物、水稻、土肥、水生、水产和农经等各方面的专家和学者会聚一堂共同研讨进一步发展稻—鱼结合的种养殖业问题。近年来我国在稻—鱼共生的试     

稻鱼高产模式技术要点

1990～1993年,湖南零陵地区水产站承担了湖南省科学技术委员会下达的“稻鱼高产模式研究”科研项目。经四年的反复实践研究,确立了“田凼结合养鱼”这一稻鱼高产模式。四年共实施4328亩,产鱼363.35吨,产稻谷4055.43吨。其中1993年实施面积1150.8亩,产鱼157.2炖,亩平136.6kg;产稻谷1039.98吨,亩平903.7kg。稻鱼总产值201.1万元,亩平1747.48元,纯收入129.42万元,亩平1124.60元,投产比1:2.81。1993年底已通过省级技术鉴定。现将稻鱼高产模式的主要技术要点介绍如下:     

稻鱼高产模式研究报告

1990—1993年进行稻鱼高产模式研究，确立了“田凼结合养鱼”这一稻鱼高产模式，分析了“鱼凼”与“鱼溜”，“鱼池”的基本区别，提出了“鱼凼”建设的标准和稻鱼高产配套技术。4年共实施面积288．52hm^2，产鱼363．35t，稻谷4055．43t。总产值533．20万元，每hm^2平18970．4元，其中1993年实施面积76．72hm^2，产鱼157．2t，每hm^2产2149kg，稻鱼总产值201．1万元，纯收入129．42万元，每hm^2平16869．15元，投产比1：2．81。     

Relative influences of environmental and spatial factors on stream fish assemblages in Brazilian Atlantic rainforest

Understanding the role of local and spatial factors in the structuring of aquatic communities is a goal in ecology. The hierarchical structure of stream systems provides opportunities to test the hypothesis that fish assemblages that are more isolated in headwaters are structured by local and/or regional variables. Fishes and abiotic data were collected in 18 stream reaches from two hydrographic basins in the Brazilian Atlantic rainforest. The variance of species composition was partitioned into fractions explained by environmental and spatial factors. The pure environmental fraction explained ≈17% of variance and was represented by regional, habitat availability/heterogeneity and perturbation gradient. The pure spatial fraction explained ≈15% of the individual fraction. Environmental data revealed a species sorting process, and the spatial effect might be a result of different dispersal routes that fish performed during the formation of the hydrographic basins, actual land use and water resources management. The importance of maintaining connectivity in these systems was emphasised because it cannot be guaranteed that the dispersion ability of species is still occurring under current land use change.
