答：眾所周知，魚類都是通過水體的溶解氧生存，在養殖時因為場地的限制還有養殖密度較高，常常會致使溶氧不足的情況，這樣草魚會活活悶死。而夏天高溫，易造成悶熱的環境，所以增氧時高溫期必須的手段，給水體增氧一般有三種方法，一種是空氣自然溶氧，二是植物光合作用增氧，三是通過人工的增氧器增氧。在夏天**種方法是不適合的，第二種限制較大，比如在晚上時沒有陽光，浮游植物不能制造氧氣，相反還要消耗水體的溶氧，所以在夏天一般要實行人工增氧。

　　草魚是眾多魚類中的一種淡水魚，在我國的分布范圍是非常廣的。草魚的肉質非常鮮嫩，并且細刺少甚至沒有，是很多人都比較喜歡吃的一種魚類。草魚的生長速度非?？?，有著較高的經濟效益，是我國養殖面積**的魚類之一。根據我們的銷售案例與客戶口碑，常見的魚塘人工增氧方式有表面曝氣增氧、水底曝氣增氧兩種!表面曝氣增氧適用于養殖密度低，水比較淺的魚塘養殖使用!水底曝氣增氧適用于高密度深水域的水產養殖!

　　客戶可根據自己魚塘的水深、面積、密集等決定選用什么方式進行增氧!表面增氧設備推薦選用我廠生產銷售的噴泉曝氣機，該設備浮在水體表面，通過不停的將水噴向空中落下的方式進行增氧。同時，該設備分別有220伏、380伏、太陽能等三種不同電壓的供電方式!客戶可根據自己的實際情況與需求進行選擇!

　　水底增氧設備推薦選用沉水風機、羅茨風機或環形風機與PE管、曝氣盤等組合形成底部曝氣增氧系統!三種風機中，環形風機適合水深在1.5米左右的面積在15平方米左右的魚塘增氧，沉水風機與羅茨風機適合在水深3米內的面積大成規模的魚塘進行增氧!其**的區別是安裝方式不同，沉水風機安裝在水下，噪音低、散熱好后期維護時比較麻煩!羅茨風機安裝在岸邊，噪音比沉水風機要大一些，后期維護時比較方便!

　　所以，養殖草魚的魚塘主們，需要根據自己的魚塘面積、密度、水深、供電方式等條件進行選擇適合自己的草魚增氧方式!至于其效果，水底增氧的方法相比于表面增氧的效率要高一些!溶解氧含量也比較高一些，同樣的造價也比表面增氧的造價要高!

　　Which kind of aerobic effect is good for cultured Grasscarp

　　As we all know, fish live through dissolved oxygen in the water body. Due to the limitations of the site and the high breeding density, it often leads to insufficient dissolved oxygen, so Grasscarp will suffocate alive. However, high temperature in summer can easily create a muggy environment, so oxygenation is a necessary means in high temperature period. There are generally three methods to oxygenate water: one is natural dissolved oxygen in the air, the other is plant photosynthesis, and the third is artificial aerator. In summer, the first method is not suitable, and the second method has relatively large restrictions. For example, in the absence of sunlight at night, phytoplankton cannot produce oxygen. On the contrary, it also consumes dissolved oxygen in the water body. Therefore, artificial oxygenation is generally implemented in summer.

　　Grasscarp (Ctenopharyngodon idellus) is a kind of freshwater fish, which is widely distributed in China. Grasscarp is a kind of fish that many people like to eat because its meat is very fresh and tender with few or no fine spines. Grasscarp grows very fast and has high economic benefits. It is one of the largest fish in China. According to our sales cases and customers' word-of-mouth, there are two common methods of fish pond aeration: surface aeration and underwater aeration! Surface aeration is suitable for fish pond culture with low culture density and shallow water! Bottom aeration is suitable for aquaculture in high-density deep waters!

　　Customers can decide what method to use to increase oxygen according to the depth, area and density of their ponds! It is recommended to select the fountain aerator produced and sold by our factory as the surface oxygenation equipment. The equipment floats on the surface of the water body and increases oxygen by constantly spraying water into the air. At the same time, the equipment has three different voltage power supply modes: 220 V, 380 V and solar energy! Customers can choose according to their actual situation and needs!

　　It is recommended to select submerged fan, Roots fan or annular fan combined with PE pipe and aeration disk to form bottom aeration and aeration system for underwater aeration equipment! Among the three types of fans, the annular fan is suitable for oxygenation in a fishpond with a water depth of about 1.5 meters and an area of about 15 square meters, and the submerged fan and Roots fan are suitable for oxygenation in a large-scale fishpond with a water depth of less than 3 meters! The only difference is that the installation method is different. The submerged fan is installed underwater, with low noise and good heat dissipation. It is troublesome in later maintenance! Roots blower is installed on the bank, and its noise is higher than that of submerged blower. It is more convenient for later maintenance!

　　Therefore, fishpond owners who breed Grasscarp need to choose their own Grasscarp aeration mode according to their own fishpond area, density, water depth, power supply mode and other conditions! As for its effect, the efficiency of underwater oxygenation is higher than that of surface oxygenation! The content of dissolved oxygen is also higher, and the same cost is higher than that of surface oxygenation!
