浅谈北方淡水养殖中的问题及应对(2)

breeding industry problems, and to promote the northern freshwater breeding industry development measures put forward some countermeasures.

北方淡水饲养中存在的疑问，我国北方淡水饲养业的开展前史不断，可是由于商场供应、饲养技艺等要素的制约，当前仍然处于低迷状况。经过关联研讨者的活跃研讨，总结出一下几点，在北方淡水饲养中存在的疑问。淡水饲养鱼类迸发性疾病，在饲养业中，迸发性疾病的危害性是显而易见的，它严重影响着饲养业的开展，尤其是北方淡水饲养业中的淡水饲养鱼类的迸发性疾病。这类型的迸发性疾病的发作时刻短、延伸规模广、医治较难，并且许多种鱼类关于这类型迸发性疾病都没有较强的抵抗力，致使这类型的迸发性疾病一旦迸发，则会敏捷延伸，并且跟着时刻延伸、这类疾病的抗药性增强，危害性将会更大。在2006年，黑龙江佳木斯区域迸发这种急性的归纳型淡水饲养鱼类疾病，危害了近千家渔户的五万多亩饲养区，鱼类逝世400多万kg，丢失更是直接打到千万元。

Northern freshwater feeding in the presence of doubt, in the north of our country water feeding industry carried out before the history, but due to the restriction of market supply, feeding techniques and other factors, the current is still in the downturn. Through active research related research, summarizes some, in the north of freshwater feeding in the presence of doubt. Freshwater fish feeding burst disease, in

the breeding industry, harmfulness burst disease is obviously, it seriously affects the development of husbandry, especially northern freshwater farming of freshwater fish feeding burst disease. Time this type of explosive seizure short, extended range, cure is more difficult, and many species of fish on this type of explosive diseases are not strong resistance, leading to the types of burst disease once burst, will be agile extension, and as time extended, this kind of disease resistance, may be even more dangerous. In 2006, Heilongjiang Jia Musi regional burst the acute induction freshwater rearing of fish diseases, harm of nearly 1000 fishermen's 50000 acres of feeding, fish died about 4000000 kg, lost more directly to tens of millions of dollars.

淡水饲养饲料的合作，我国北方淡水饲养业尽管由来已久，可是渔户关于饲养饲料的配比、选择疑问仍然存在很大的误区。遭到传统思维的影响，许多渔户关于饲料配比的知道严重缺乏，以为只需最贵的、国外产的饲料就是最佳的饲料，对饲料的成分、配比，不一样淡水饲养种类所需养分的需要不一样等要素，都没有很好地思考在内；别的，由于饲料的生产厂家多，品牌质量乱，饲料商场的办理力度不行，也是影响北方淡水饲养业开展之后的要素。并且，生态带还有些质量的确很好的饲料，可是其价钱却不是大多数渔户所能承受的，致使北方淡水饲养的饲料疑问一向没有得到很好的处理。

Freshwater feedstuff cooperation, in the north of China, fresh water farming despite long-standing, but the fishermen about raising feed ratio, choose the question still remains a lot of misunderstanding. Influenced by traditional thinking, many fishermen know about feed lacking, that only the most expensive, feed production abroad is the best feed, composition, ratio of feed, need not the same species of freshwater feeding nutrients required for different elements, there is no good thinking, other;, because feed manufacturers, brand quality, feed store management is not good, also affect the northern freshwater breeding industry development after the elements. And, there is very good quality forage, but its price is not the most fishermen can bear, resulting in northern freshwater rearing feed question has not been handled well.

饲养种类紊乱，由于大多数的渔户短少体系的商场调查，致使他们关于商场的供求关系等疑问，知道缺乏，然后形成饲养种类紊乱的情况严重。别的，在大多数的北方淡水饲养区，紫叶李多以传统的饲养种类为主体，这些饲养种类的数量多，这样在价钱上就会下降。

Breeds disorder, since most of the fishermen missing system market survey, leaving them on market supply and demand relations of doubt, know deficiency, then forming breeds disorder in serious condition. Other, feeding areas in most

northern freshwater species, to raise the traditional as the main body, the number of breeding species, it will drop in price.

淡水池塘养殖的环境问题分析及解决措施

摘要：传统淡水池塘养殖造成了水体富营养化和氮失衡两大主要环境问题，异位修复技术和原位修复技术作为解决这种问题的两大主要研究成果，为实现环境保护和经济效益提供了一条新的思路——淡水池塘生态合作养殖模式，为淡水池塘养殖业的发展提供了新的道路。

目前，淡水养殖业是我国渔业发展中的重点，其产量在水产养殖中逐年呈上升比率，淡水养殖作为水产养殖中的重点，过去传统的密集型养殖方式暴露了诸多弊端，限制了淡水养殖产业的升级，因此，分析和解决目前淡水池塘养殖中所面临的环境问题，寻求更好的解决措施吗，推进淡水池塘养殖业的健康、快速发展是我们需要密切关注的问题。下面我们针对传统淡水养殖中的环境问题略作分析，并结合最近产业研究成果原位修复技术和异位修复技术来分析下其解决之道。

1 淡水吃糖养殖环境问题分析

从目前淡水养殖的局面来看，传统养殖的高密集型所造成的弊端与水体富营养化、氮失衡是造成环境问题的三大主凶之一。 传统淡水养殖采用高密度、高投饵率、高换水率进行养殖，对于环境的危害是巨大的，同时近年因饲料投放问题造成的水体富营养化也是限制淡水池塘养殖行业发展的瓶颈。虽然养殖水平随着技术研究的突破不断提升，单位水体的鱼载力也在提升，但是鱼类代谢 …… 此处隐藏：2038字，全部文档内容请下载后查看。喜欢就下载吧 ……
