近日，國內很多地區溫度不斷提高，有些地區甚至出現了42攝氏度的高溫天氣!天氣熱了，魚類生長發育也進入了充沛的時節，因為魚類進食量增多，糞便增加，也使飼養水體非常容易下降，水質的下降會導致各種各樣魚病的產生。因此，魚塘養殖戶要時刻注意水體溶解氧含量!與此同時，因為高溫天氣，氣候干燥，水的溫度比較高，大暴雨增加等眾多不利條件，對飼養的魚類會發生較大危害，必須加強管理，從容應對，完成池塘飼養的翠綠色、綠色生態、高效率、安全運行。高溫天氣氣溫池塘飼養管理方法應做好下列幾層面的工作中：

　　一、做好放魚早期的完全消毒殺菌。

　　針對夏天推廣的魚種，預留池塘在放魚苗早期要開展清塘、曬塘和全方位消毒殺菌。徹底消除老舊的飼養池塘污泥，消除池塘有害物，通過完全曝曬后，消除池塘底端的病菌和病原菌，并應用生石灰粉完全消毒。與此同時，對池塘進排水設備、塘埂、塘坡開展結構加固和維護保養，保證池塘的安全性、牢固、不滲漏。

　　二、做好水體管控。

　　夏天進到雨熱同時期的時節，持續高溫不斷長、大暴雨增加，水體變化大，與此同時，因為魚類進食量增加、糞便增加，水里高錳酸鹽指數和亞硝酸鈉水平高，易于導致水體下降，因而，立即調整水體看起來至關重要和急切。水體調整應以維持水體的“肥、活、嫩、爽”為總體目標。

　　(1)調整好水體的pH值指標值，魚類生長發育適合的技術指標是6.5-8.5中間，pH值指標值過低，水體偏酸，非常容易使魚類遭受病菌和寄生蟲病的感柒，pH值指標值太高，水體呈堿性，非常容易導致藻類植物增加，造成爛鰓等魚病。

　　(2)管控溶氧。魚類生長發育一般規定*少溶氧3mg/L，一些優良種類必須做到5mg/L之上，**溶氧的辦法目的是為了：充注自來水，維持水體清爽;打開增氧泵，**水里氧氣含量;管控淤泥，清除池塘底端的病原菌、裂頭蚴等有害物，**水里氮、磷等微量元素;開展生物制品調整水體，常見的生物制品有光合菌、枯草芽孢菌、硝化菌等，能夠合理抑止病原菌和病菌的生長發育，推動水體中致癌物質的溶解，推動水體**物的循環系統，維持水體的清爽度和清晰度。

　　三、做好科學合理投喂。

　　投喂精飼料要堅持“四定”標準，即：按時、精準定位、定質、定量分析，維持精飼料新鮮的，沒有雜質，不質變，依據氣溫、溫度、水體、魚身尺寸等要素，及時調整投喂頻次和投喂量，一般以養殖魚進食量的八成飽*合適，投餌率日投喂量為魚身凈重的3%-5%，在下雨天要酌量降低。

　　四、做好魚病防止。

　　夏季氣溫高，魚病高發，要加強魚病的預防工作中，堅持不懈防患于未然，醫治輔助，綜合防治的標準，保證勤巡塘、多觀察，發覺魚病要及時開展解決和醫治，預防魚病的大規模出現。

　　五、做好平時養管工作中。

　　夏天天氣多變，暴風雨**，水體不穩定，要堅持多巡塘、多觀察，留意魚類的活動軌跡、進食情形等趨勢，發覺擺動遲緩和進食不暢的要及時分析原因、做好處理。與此同時，要及時處理撈起來魚死，清除水里枯葉、臟物，消除池塘邊的野草，維持池塘的清理和環境衛生，按時對池塘用生石灰粉和漂白劑等藥品開展全方位消毒殺菌。并做好每日的飼養系統日志，詳盡紀錄每日的加料、服藥、生產制造、市場銷售等各類紀錄，便于于數據分析和立即采取相應的技術措施，持續吸取經驗，**種植水準。

　　做好養殖管理的同時，也要注意水體增氧設備的開啟!通常，水產養殖魚塘分為戶外魚塘養殖、大棚內養殖、帆布池養殖三種。在針對這幾種情況養殖魚苗增氧的時候，用戶可以使用羅茨風機、漩渦風機、沉水風機等風機設備進行增氧。

　　今天我們簡單介紹一下羅茨風機，在魚塘增氧的時候風機主要是提供了氣源，清潔的空氣有助于水產養殖增氧使用。

　　使用羅茨風機好處：

　　1、羅茨風機輸出的是清潔的空氣，因為風機的結構兩個三葉輪互不接觸，所以轉子內不用加潤滑油，排出氣體不含油是其優勢之一;

　　2、排出的風量穩定，比如1分鐘內出氣量10個立方，那么機子不會受到壓力的變化而變化，在水位1米的時候出氣量也是10個立方，當在4米水位曝氣的時候，出氣量在9.8個立方左右，風量的變化很小;

　　3、羅茨風機排氣壓力高，對比漩渦風機，羅茨風機的工作壓力算是比較高了，工作范圍在10-90kpa左右，可以滿足日常大部分用戶的魚塘使用。

　　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.
