你这是想要一篇学术论文！

一、什么是水产生态养殖养鱼的朋友都知道，我们养鱼的鱼塘是一个复杂的生态系统。水面以上有阳光，空气；塘基上有陆生植物；水是有鱼、有各种水生植物、昆虫、蚤类、藻类、真菌、细菌、病毒、以及有机物和无机盐。池底有淤泥，同样也生长得上述生物及有机物和无机盐。它们之间存在着相养、相生、相帮、相克等极其复杂的关系，生态养殖就是合理利用它们之间的相生、相养、相帮、相克的关系，生产我们所需要的水产品。合理利用它们之间的关系，不管是从经济效益还是社全效益和环境效益，都能达到一个最好的结果，这就是生态养殖。二、什么是绿色无公害水产品首先，养殖基地必须经过认证，其中最主要的是大气、土壤、水质必须符合《农产品安全质量----水产品产地环境要求》国家标准和《无公害食品淡水养殖用水水质》农业部标准的要求；其次，必须按照无公害水产品的生产技术操作规程进行养殖，从苗种放养到饲料、肥料、渔药等一切投入品的使用，再到产品的捕捞、贮运、质检、包袋、上市的各个环节均需符合相关标准或规范的要求；第三，产品必须经过政府指定的权威质检机构的抽检、完全合格并颁证后方能进入市场销售。三、水产生态养殖有何意义1，环境效益：传统的养殖模式，不但用水量大，而且施用的大剂量的国家违禁药品，如硫酸铜、孔雀石绿、敌百虫、呋喃类药等，随着大量换水，对坏境造成很大的破坏。同时对于鱼塘底质也造成难以估量的损害，使鱼塘生态环境遭到极大的破坏，恶性病源微生物大量增殖。生产的水产品通过食物链的扩散，不但对人的健康造成了损害，对环境的破环也是巨大的。2，社会效益：随着人民生活水平的提高，人们环保意思的加强，人们更加注重食品安全性，加上我国加入WTO，水产品要进入国际市场，必须达到别国的食品安全标准，因此，为了国人的身体健康，和中国水产品出口的高额利润，必须执行生态养殖。3，经济效益：传统的养殖模式，已经造成了鱼池微生物菌群严重失衡，病原微生物巨增，抗药性增强，养鱼户不得不加大药物用量，结果鱼病治不好，鱼体受伤，产量锐减，品质下降，成本增加，泛塘事件屡屡发生。这就是我们大通湖及周边地区常规鱼养殖户放弃养鱼，鱼塘种棉花怪现像发生的主要原因。湖北养鱼户率先应用了微生物制剂生态养殖法，已产生了可喜的成绩，他们生产的草鱼以低于我地每公斤1元的绝对优势，占领着湖南岳阳鲜鱼市场和其它湖南部份鲜鱼市场。在黄鳝养殖上也是用药泡着，隔三差五施药，严重影响了黄鳝的生长和产品品质，使养殖成本居高不下。更有甚者，越冬黄鳝成箱成箱的死亡，给我们不施执生态养殖敲响了警钟。我们养殖户必须改变生产观念！走出传统养殖模式的怪圈。四，倡导生态养殖的可行性随着我国水产科学的进步，已经为生态养殖研究出了系统的技术，制定了科学的标准，同时也研究出了适合生态养殖的高效、低残留、低剂量的水产用药，特别中成药和中药提取物，和有益微生物制剂天意EM原露，深圳希科安公司生产的动物强壮剂饲料添加剂-活力素。更是我们施执生态养殖有了足够的保障。广东的亩产草鱼过吨半的事例，同样也可以作为生态养殖的可行性的佐证。五、怎样实行生态养殖生态养殖包含的范畴很宽，它主要有如下几种。(一)人工生态环境养殖法。(二)多品种立体养殖法。(三)开放式流水或微流水养殖法。(四)全封闭循环水工厂化养殖法。(五)水产品与农作物共生互利养殖法。(六)使用微生物制剂养殖法。因为篇幅的限制，我这里不能作一一的阐述，就着重对使用微生物制剂法加以说明，如果对前五种方法感兴趣的朋友，请到我部咨询。 什么是微生物制剂养殖法：近10年来，微生物活菌制剂逐渐在水产养殖中得到应用推广，这给无公害健康养殖生产提供了有力的保障。目前较多使用的产品有光合细菌制剂，芽胞杆菌、乳酸杆菌制剂，天意EM原露等。他们能分解水体中的残饵、鱼粪等有机质，降低水中的氨氮含量，使养殖水体变清洁，从而改善了环境；他们能改善养殖对象的胃肠道内环境，增强食欲，促进生长，提高饲料报酬；他们还能强化养殖对象的免疫功能，提高免疫力，增强抗病能力；还能强化有益菌群，防止和减少细菌性疾病的发生与蔓延。I. What is the aquatic eco-farmingFish friends are aware that we fish ponds is a complex ecosystem. The sun above the water, air; Tong have land-based plants; water is a fish, a variety of aquatic plants, insects, fleas, algae, fungi, bacteria, viruses, and organic and inorganic salts. Mud bottom there is also growing these organisms and organic and inorganic salts. Between them there is a phase dependent, with students such as grams of extremely complex relations, ecological farming is the rational use of their students with dependents,compared the relationship between grams, production of aquatic products we need. Rational use of the relations between them, whether from economic or social benefits and environmental benefits the whole, to achieve the best results, this is the , what is the green pollution-free aquaticFirst of all, the breeding base to be certified, of which the most important thing is the atmosphere, soil, water quality must be consistent with "the quality safety of agricultural products ---- environmental requirements of aquatic origin," National Institute of Standards and "pollution-free water for the water quality of freshwater aquaculture products," the Ministry of Agriculture standards requirements; Second, pollution-free aquatic products in accordance with the rules of production technologies for breeding, from fry stocking to feed, fertilizer, Drugs, such as the use of all inputs, to fishing products, storage and transportation, quality inspection, bag listed to comply with all aspects of the relevant standards or norms; the third, the product must go through the authority designated by the Government of the sampling inspection agencies, fully qualified and licensing in order to enter the market after the , what is the significance of aquatic eco-farming1, environmental benefits: the traditional mode of farming, not only large quantities of water, and the application of large doses of countries banned substances, such as copper, malachite green, trichlorfon, furans and other drugs, with a large number of the water, on the bad habitat caused great damage. Substrate for the fish ponds at the same time also caused incalculable damage to fish ponds in the ecological environment has been greatly damaged, a large number of malignant proliferation of pathogenic micro-organisms. Produced by the proliferation of aquatic products through the food chain, not only on human health damage, environmental destruction is , social benefits: With the improvement of people's lives, it is meant to strengthen environmental protection, people pay more attention to food safety, coupled with China's accession to the WTO, aquatic products to enter the international market, other countries must meet food safety standards, therefore, To the health of the people, and China, the export of aquatic products of high profits, they must be the implementation of , cost-effective: the traditional mode of farming, has caused a serious imbalance in Yuchih microbial flora, pathogenic microorganisms by macrophages, enhanced resistance, the fish farmers had to increase the drug dosage, the results of fish diseases body injuries, sharp drop in output, decline in quality, cost increase has occurred frequently Tong Pan. This is our Chase Lake and the surrounding areas of conventional fish farmers to give up fish, fish ponds is strange to produce much cotton as the main reason for the occurrence. Hubei mariculturists microbial agents take the lead in the application of eco-farming method, has produced gratifying results, they produced less than I in grass carp to 1 yuan per kilogram of absolute superiority, occupied the fish market in Hunan Yueyang in Hunan Province and other parts of fresh fish market. In the rice field eel is also a drug culture on the bubble, andapplication, Monopterus seriously affected the growth and product quality, so that the cost of high culture. Even worse, the winter Monopterus boxes into the death of me, to us they are no wake-up call ecological farming. Fish farmers must change our production concept! Out of the traditional model of the cycle of , promote the feasibility of eco-farmingWith the progress of China's Aquatic Sciences, has been developed for the ecological farming system technology, has developed standards for science, but also for eco-culture has developed a highly efficient and low-residue, low-dose administration of fisheries, particularly in medicine and Chinese extract, and beneficial microbial preparations reveal the original EM Providence, Shenzhenproduced tonic animal feed additives - Huolisu. Shi Zhi and it is eco-farming has been adequately protected. Guangdong's per-mu yield of grass carp have been a half tons of examples, the same can also be used as the feasibility of eco-culture of , how to implement eco-farmingEcological farming includes a wide scope, it has the following several major. (A) the ecological environment of artificial breeding method. (B) three-dimensional multi-species breeding method. (C) open-water or water micro-culture method. (D) closed the factory farm method of circulating water. (V) aquatic symbiotic and mutually beneficial crop breeding method. (Vi) the use of microbial culture preparation method. Because of space limitations, I can not be here on the 11, we focus on the use of microbial preparations to illustrate this method, if the methods of the former five friends interested in, please go to the Department of advice I have. What is the breeding method microbial agents: the past 10 years, gradually Microorganisms in aquaculture are applied to promote the health of this culture to the pollution-free production provided strong protection. At present, more products are used preparations of photosynthetic bacteria, Bacillus, Lactobacillus preparations, such as an act of God reveal the original EM. They can break down残饵water, fish manure and other organic matter, reduce the ammonia content in water, so that culture change clean water, thereby improving the environment; they can object to improve the breeding environment of the gastrointestinal tract, enhance the appetite, promote growth and improve feed remuneration; they can strengthen the immune function of the target culture and enhance immunity, enhanced disease resistance; can strengthen the beneficial bacteria to prevent and reduce the occurrence of bacterial diseases and the spread.

水产养殖中使用微生态制剂的报告 近年来, 在水产养殖业中, 微生态制剂作为绿色饲料添加剂、水质改良剂以及对鱼类健康、预防疾病、 促进生长和品质改善所起的显著作用, 越来越被人们所重视, 并以其无毒副作用, 无耐药性, 无残留污染, 效果显著等特点逐渐得到广大水产养殖者的认可。近年来, 微生物技术在水产养殖中的应用越来越广泛, 利用微生物制剂进行水产健康养殖, 实现无公害养殖, 已成为发展趋势。 具体来源：

工厂化水产养殖系统 海水循环水养殖系统，它集现代工程、机电、生物、环保及饲料科学等多学科于一体，是当今世界海水养殖产业发展的必然趋势，在发达国家早已兴起发展，进展很快。在我国过去许多国家开发项目虽有引进，不但因其高昂的设备价格和运行成本难以普遍推广使用，也因其不适合我国的自然条件而报废。国内对海水循环水养殖系统亦进行很多的开发研究，也取得了一定的成果，由于受系统设计基本采用污水处理设计理念的局限，受采用现行工业通用泵、阀、过滤、增氧、杀菌、检测、自控……等设备的制约，设备的耐用性、耐腐蚀性、检测仪器的可靠性、全系统的配套性、易操作性、易维护性存在着不少这样或那样的问题，致使国内在开展海水循环水养殖系统上，虽然投入了可观的人力，财力，却因设施和设备的价格、能耗、运行成本同样居高不下，水处理效果达不到国家规定的养殖水标准，至今无法推广应用。为解除这个瓶颈，北京今明远大科技有限公司针对国内工厂化养殖系统和关键设备存在的问题，已进行了四年完整系统的多学科集成研究和技术创新，研究开发出适合中国国情，具有自主知识产权的海水循环水养殖系统和设备，在保证水质的前提下，最大程度的降低了能耗与系统工程和设备造价，让养殖企业买的起、用的起、维护得了，产量成倍提高，消耗大幅度下降，有明显的社会经济效益。其特点是：养殖废水处理流程是通过水驱动的全塑微滤机祛除水中固体颗粒，通过微生物池祛除氨氮，通过-沉淀池沉淀，通过-泡沫分离器祛除悬浮物及蛋白质，通过-高效溶氧装增氧，通过-紫外线杀菌，通过-调温和 pH 值调节后再进入养殖池循环使用。水质监测系统可自动检测水的盐度，溶氧量，pH、温度做出相应的控制或报警，保证达到水产养殖需要。养殖池的气动定时排污阀利用养殖池水旋转聚污效应，定时将池中心聚集的粪便、残余饵料排掉，减轻水处理的负荷有效的保证水质。上述每个关键的工艺环节，关键设备均使用的是我公司自主开发，设计、研制，所以效果和效益与以往明显不同。技术指标：经过水处理系统，其养殖用水在满足NY5051、NY5052（无公害食品，淡水及海水养殖用水水质标准）和DB12/177—2003（海水养殖废水排放标准）的基础上，养殖用水达到以下指标：透明度达到1m以上、溶氧达到7-12mg/L、氨氮低于、亚硝酸盐低于。水深、盐度、温度等重要因子可自动监测，临界报警，按设置好的指令启动相关设备，防止在处理水中的人为干扰。二、结合海水循环水养殖系统水处理系统的特点开发出适用于海水水产养殖的专项设备和装置：（1）、水驱动的全塑微滤机：微滤机应用物理过滤技术快捷、经济的去除养殖废水中的剩余残饵和养殖生物排泄物等悬浮颗粒。微滤机的全部部件由非金属塑料材料制成。可承受各种海水、酸、碱长期腐蚀。省电节能，筛网维护经济方便，价格仅为目前使用的微滤机价格60%。（2）、高效纯氧溶氧增氧器：由于纯氧高度回收利用，氧气利用率大于95%。富氧水的氧含量可达到 45 毫克／升。节能降耗使运行成本大为降低。适用于淡、海水养殖业、活鱼运输等水体增氧。（3）自清洁型紫外线水处理杀菌装置：提供一种无需拆卸石英玻璃套管而能自动保持其清洁的紫外线水处理装置。它自身具备清洁功能，可以在系统运行状态下对灯管进行擦拭和清洗，用以避免机械擦洗设备的复杂维护和高昂成本问题，也避免传统的人工方式由于无法擦拭或擦拭不方便、不清洁等因素所造成的紫外灯灭菌效果差的问题。使用紫外线杀毒可避免在养殖中大量使用农药，使水产品真正成为绿色食品。（4）气动阀门：对阀门的自动控制是海水循环水养殖系统的关键设备，没有它就无法建立现代化的水产养殖系统，也无法实现对系统的科学管理，依据水产养殖系统设计的气动阀门避免如现有控制阀门结构中采用电机，减速机，汽缸活塞等大量复杂的机械设备，增加了可靠性，降低了成本30-70%。其材料全部为合成有机材料，从根本上防止了水尤其是海水的腐蚀。 （5）无曝气生物净化装置：利用微生物的吸收、代谢等作用, 达到降解水体中有机物和营养盐的目的，本装置依海水循环水养殖系统水循环的特点、生物菌群的生存特性和生物载体的特殊结构，运用合理的布流，实现了在生物净化池无曝气的情况下， 生物保持高度活性、增加与水的接触面积，强化降解功能。同时，动态生物载体不堵塞，污物便于清洗和排放，免除了反冲洗的能耗和劳动强度，可长期不间断稳定运行。（6）蛋白分离器：利用微气泡凝聚水中的有机杂质、胶状蛋白，使之与水分离的同时祛除二氧化碳等水中的有害气体，达到水净化的目的。（7）无接触盐度控制器：即克服了人工测试可靠性、准确性差的问题，也避免了现代测试仪器传感器易损坏，维护难的问题。实时对盐度的在线监控。（8）水质多路采样系统：有效的降低了测试仪器和传感器的使用数量，降低投资费用和维护强度，方便用户。（9）监测报警和控制系统：水位、盐度、溶氧、水温等重要的水环境因子，可自动监测，按设定要求分级报警（车间、场长、董事长）并可实现自动控制。上述产品的应用不仅仅局限于海水循环水养殖方面，在水产的塘养和运输方面也有广泛的开发应用前景。例如塘养方面使用高效纯氧溶氧增氧器和气动阀门在电耗相同的情况下水中溶氧全天维持在5-6mg/L，且水无分层，与气动定时排污阀配合使用，利用养殖池水旋转聚污效应，定时将池中心聚集的粪便、残余饵料排掉，保证水质，减少底泥处理量，塘底不会产生有毒气体，运行管理方便，处理过的水质好，能成倍提高鱼的单位面积高量、减少病害，降低饵料消耗，同时节水、节电、环保。在水产运输方面用高效纯氧溶氧增氧器，有效保证水体溶氧，增加运输密度，提高存活率，降低运输成本。高效纯氧溶氧增氧器还可在水产品的困养暂养发挥作用，祛除水产品的土腥味，提高水产品的质量化。
