/ / / /浅谈北方淡水养殖中的问题及应对Problems and Countermeasures of the north in fresh water aquiculture 北方淡水饲养的开展前史并不算短，可是由于遭到种种要素的制约，其开展速度一向不是很好。可是，关联研讨者在研讨北方淡水饲养中存在的疑问时，还应该注意到北方淡水饲养业的开展潜力。跟着经济的开展，大家生活水平的进步，大家关于事物的需要也越来越高，渔业产物越来越被广阔大众所承受，尤其是一些渔业的“无公害的绿色食品”，大家对它们的喜爱度也越来越高。所以，本文将要点研讨北方淡水饲养业中存在的疑问，进而对推进北方淡水饲养业的开展对策提出几点对策。 Northern freshwater breeding development history is not short, but because of the constraints by various elements, the pace of development is not always good. However, researchers in the study of association northern freshwater breeding in doubt, should also pay attention to the north of freshwater breeding industry development potential. With economic development, people living standards, people about things that need more and more high, fishery products is more and more widely accepted by the masses, especially in some fisheries pollution-free green food, the higher your love for them is more and. So, this paper will discuss the north of freshwater 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 fishermens 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 def
