近日，国内很多地区温度不断提高，有些地区甚至出现了42摄氏度的高温天气!天气热了，鱼类生长发育也进入了充沛的时节，因为鱼类进食量增多，粪便增加，也使饲养水体非常容易下降，水质的下降会导致各种各样鱼病的产生。因此，鱼塘养殖户要时刻注意水体溶解氧含量!与此同时，因为高温天气，气候干燥，水的温度比较高，大暴雨增加等众多不利条件，对饲养的鱼类会发生较大危害，必须加强管理，从容应对，完成池塘饲养的翠绿色、绿色生态、高效率、安全运行。高温天气气温池塘饲养管理方法应做好下列几层面的工作中：

　　一、做好放鱼早期的完全消毒杀菌。

　　针对夏天推广的鱼种，预留池塘在放鱼苗早期要开展清塘、晒塘和全方位消毒杀菌。彻底消除老旧的饲养池塘污泥，消除池塘有害物，通过完全曝晒后，消除池塘底端的病菌和病原菌，并应用生石灰粉完全消毒。与此同时，对池塘进排水设备、塘埂、塘坡开展结构加固和维护保养，保证池塘的安全性、牢固、不渗漏。

　　二、做好水体管控。

　　夏天进到雨热同时期的时节，持续高温不断长、大暴雨增加，水体变化大，与此同时，因为鱼类进食量增加、粪便增加，水里高锰酸盐指数和亚硝酸钠水平高，易于导致水体下降，因而，立即调整水体看起来至关重要和急切。水体调整应以维持水体的“肥、活、嫩、爽”为总体目标。

　　(1)调整好水体的pH值指标值，鱼类生长发育适合的技术指标是6.5-8.5中间，pH值指标值过低，水体偏酸，非常容易使鱼类遭受病菌和寄生虫病的感柒，pH值指标值太高，水体呈碱性，非常容易导致藻类植物增加，造成烂鳃等鱼病。

　　(2)管控溶氧。鱼类生长发育一般规定最少溶氧3mg/L，一些优良种类必须做到5mg/L之上，提升溶氧的办法目的是为了：充注自来水，维持水体清爽;打开增氧泵，提升水里氧气含量;管控淤泥，清除池塘底端的病原菌、裂头蚴等有害物，提升水里氮、磷等微量元素;开展生物制品调整水体，常见的生物制品有光合菌、枯草芽孢菌、硝化菌等，能够合理抑止病原菌和病菌的生长发育，推动水体中致癌物质的溶解，推动水体有机物的循环系统，维持水体的清爽度和清晰度。

　　三、做好科学合理投喂。

　　投喂精饲料要坚持“四定”标准，即：按时、精准定位、定质、定量分析，维持精饲料新鲜的，没有杂质，不质变，依据气温、温度、水体、鱼身尺寸等要素，及时调整投喂频次和投喂量，一般以养殖鱼进食量的八成饱最合适，投饵率日投喂量为鱼身净重的3%-5%，在下雨天要酌量降低。

　　四、做好鱼病防止。

　　夏季气温高，鱼病高发，要加强鱼病的预防工作中，坚持不懈防患于未然，医治辅助，综合防治的标准，保证勤巡塘、多观察，发觉鱼病要及时开展解决和医治，预防鱼病的大规模出现。

　　五、做好平时养管工作中。

　　夏天天气多变，暴风雨提升，水体不稳定，要坚持多巡塘、多观察，留意鱼类的活动轨迹、进食情形等趋势，发觉摆动迟缓和进食不畅的要及时分析原因、做好处理。与此同时，要及时处理捞起来鱼死，清除水里枯叶、脏物，消除池塘边的野草，维持池塘的清理和环境卫生，按时对池塘用生石灰粉和漂白剂等药品开展全方位消毒杀菌。并做好每日的饲养系统日志，详尽纪录每日的加料、服药、生产制造、市场销售等各类纪录，便于于数据分析和立即采取相应的技术措施，持续吸取经验，提升种植水准。

　　做好养殖管理的同时，也要注意水体增氧设备的开启!通常，水产养殖鱼塘分为户外鱼塘养殖、大棚内养殖、帆布池养殖三种。在针对这几种情况养殖鱼苗增氧的时候，用户可以使用罗茨风机、漩涡风机、沉水风机等风机设备进行增氧。

　　今天我们简单介绍一下罗茨风机，在鱼塘增氧的时候风机主要是提供了气源，清洁的空气有助于水产养殖增氧使用。

　　使用罗茨风机好处：

　　1、罗茨风机输出的是清洁的空气，因为风机的结构两个三叶轮互不接触，所以转子内不用加润滑油，排出气体不含油是其优势之一;

　　2、排出的风量稳定，比如1分钟内出气量10个立方，那么机子不会受到压力的变化而变化，在水位1米的时候出气量也是10个立方，当在4米水位曝气的时候，出气量在9.8个立方左右，风量的变化很小;

　　3、罗茨风机排气压力高，对比漩涡风机，罗茨风机的工作压力算是比较高了，工作范围在10-90kpa左右，可以满足日常大部分用户的鱼塘使用。

　　Recently, the temperature in many areas of China has been increasing continuously, and some areas even have 42 degrees Celsius high temperature weather! The hot weather makes the growth and development of fish more abundant. The increase of fish feeding and excrement also makes the feeding water body very easy to fall. The decrease of water quality will lead to various fish diseases. Therefore, fish pond Culturers should always pay attention to dissolved oxygen content in water! At the same time, many unfavorable conditions, such as high temperature, dry climate, high water temperature and increased heavy rainstorm, will cause great harm to fish raised. Therefore, management must be strengthened and response must be calm to complete the turquoise, green ecology, high efficiency and safe operation of pond breeding. The methods of pond feeding and management in high temperature weather and temperature should do well in the following aspects:

　　I. Completely sterilize and sterilize fish in the early stage.

　　For the fish species promoted in summer, clean ponds, sunshine ponds and all-round disinfection and sterilization should be carried out in the reserved ponds at the early stage of fish larvae releasing. Sludge in old feeding pond is completely eliminated, harmful substances in pond are eliminated, pathogens and pathogens at the bottom of pond are eliminated after being fully exposed to sunlight, and lime powder is used to sterilize the pond completely. At the same time, structural reinforcement and maintenance are carried out on the intake and drainage equipment, ridges and slopes of the pond to ensure the safety, stability and seepage-free of the pond.

　　2. Control the water body well.

　　During the same period of hot and rainy season in summer, continuous high temperatures, heavy rainstorms and large changes in water bodies occur. At the same time, due to increased fish feeding and feces, high levels of permanganate index and sodium nitrite in water, water bodies tend to drop. Therefore, it seems essential and urgent to adjust water bodies immediately. The overall objective of water body adjustment is to maintain the "fertility, activity, tenderness and refreshment" of the water body.

　　(1) Adjust the pH value of water body. The suitable technical index for fish growth and development is between 6.5 and 8.5. The pH value is too low and the water body is too acidic. It is very easy for fish to be susceptible to pathogens and parasitic diseases. The pH value is too high and the water body is alkaline. It is very easy to cause increase of algae plants and cause fish diseases such as gill rot.

　　(2) Control of dissolved oxygen. The minimum dissolved oxygen is 3 mg/L for fish growth and development. Some excellent species must be above 5 mg/L. The purpose of improving dissolved oxygen is to fill tap water and keep water fresh. Open the oxygen pump to increase the oxygen content in the water; Control sludge, remove pathogenic bacteria, spargania and other harmful substances at the bottom of pond, and improve trace elements such as nitrogen and phosphorus in water; To carry out the adjustment of water body by biological products, common biological products include photosynthetic bacteria, Bacillus subtilis, nitrifying bacteria, etc., which can reasonably inhibit the growth and development of pathogens and bacteria, promote the dissolution of carcinogens in water body, promote the circulation system of organic matter in water body, and maintain the refreshment and clarity of water body.

　　3. Do a good job of feeding scientifically and reasonably.

　　Feeding of refined feed should adhere to the "four definite" standard, i.e. timely, accurate positioning, quality determination and quantitative analysis to keep the refined feed fresh, free of impurities and no deterioration. Feeding frequency and feeding quantity should be adjusted in time according to the temperature, temperature, water body and size of fish body. Generally, 80% of the feed quantity of cultured fish is the most suitable one. Feeding rate per day is 3% - 5% of the net weight of fish body, and should be reduced in rainy days.

　　IV. Prevent fish diseases.

　　Due to high temperature and high incidence of fish diseases in summer, it is necessary to strengthen the prevention of fish diseases, unremitting prevention, medical assistance and comprehensive control standards, so as to ensure frequent patrol of ponds and observation, promptly solve and treat fish diseases if found, and prevent large-scale occurrence of fish diseases.

　　5. Do a good job in usual maintenance work.

　　In summer, the weather is changeable, the storm rises and the water body is unstable. We should persist in patrolling ponds and observing more, pay attention to the movement track of fish, feeding situation and other trends. If we find that swing is slow and feeding is not smooth, we should analyze the causes and deal with them in time. At the same time, it is necessary to dispose of dead fish in time, remove dead leaves and dirt in water, eliminate weeds near the pond, maintain cleaning and environmental sanitation of the pond, and carry out comprehensive disinfection and sterilization of medicines such as lime powder and bleaching agent in the pond on time. And keep daily feeding system log, record daily feeding, medication, manufacturing, marketing and other records in detail, so as to facilitate data analysis and take corresponding technical measures immediately, draw on experience continuously and improve planting level.

　　Do a good job of aquaculture management, but also pay attention to the opening of water oxygen enrichment equipment! Generally, aquaculture ponds are divided into outdoor pond culture, in-greenhouse culture and canvas pond culture. In response to these conditions, users can use Roots blower, swirl blower, submerged fan and other fan equipment to increase oxygen.

　　Today we will briefly introduce the Roots blower, which mainly provides the air source when aerating the fish pond. Clean air is helpful for aquaculture to increase oxygen.

　　Benefits of using a Roots blower:

　　1. The Roots blower outputs clean air, because the two three impellers of the blower structure are not in contact with each other, so there is no lubrication in the rotor, and the exhaust gas without oil is one of its advantages.

　　2. Exhaust air volume is stable, such as 10 cubic meters of air volume in 1 minute, then the machine will not be subject to changes in pressure. Exhaust air volume is also 10 cubic meters when water level is 1 meter. When aerated at 4 meter level, the amount of air output is about 9.8 cubic meters, with little change in air volume.

　　3. The exhaust pressure of Roots blower is high. Comparing with the swirl blower, the working pressure of Roots blower is relatively high and its working range is about 10-90 kpa, which can meet the needs of most users in fish ponds.
