答：众所周知，鱼类都是通过水体的溶解氧生存，在养殖时因为场地的限制还有养殖密度较高，常常会致使溶氧不足的情况，这样草鱼会活活闷死。而夏天高温，易造成闷热的环境，所以增氧时高温期必须的手段，给水体增氧一般有三种方法，一种是空气自然溶氧，二是植物光合作用增氧，三是通过人工的增氧器增氧。在夏天**种方法是不适合的，第二种限制较大，比如在晚上时没有阳光，浮游植物不能制造氧气，相反还要消耗水体的溶氧，所以在夏天一般要实行人工增氧。

　　草鱼是众多鱼类中的一种淡水鱼，在我国的分布范围是非常广的。草鱼的肉质非常鲜嫩，并且细刺少甚至没有，是很多人都比较喜欢吃的一种鱼类。草鱼的生长速度非常快，有着较高的经济效益，是我国养殖面积**的鱼类之一。根据PROUMB中国版的销售案例与客户口碑，常见的鱼塘人工增氧方式有表面曝气增氧、水底曝气增氧两种!表面曝气增氧适用于养殖密度低，水比较浅的鱼塘养殖使用!水底曝气增氧适用于高密度深水域的水产养殖!

　　客户可根据自己鱼塘的水深、面积、密集等决定选用什么方式进行增氧!表面增氧设备推荐选用我厂生产销售的喷泉曝气机，该设备浮在水体表面，通过不停的将水喷向空中落下的方式进行增氧。同时，该设备分别有220伏、380伏、太阳能等三种不同电压的供电方式!客户可根据自己的实际情况与需求进行选择!

　　水底增氧设备推荐选用沉水PROBURN中文免费版下载安装、罗茨PROBURN中文免费版下载安装或环形PROBURN中文免费版下载安装与PE管、曝气盘等组合形成底部曝气增氧系统!三种PROBURN中文免费版下载安装中，环形PROBURN中文免费版下载安装适合水深在1.5米左右的面积在15平方米左右的鱼塘增氧，沉水PROBURN中文免费版下载安装与罗茨PROBURN中文免费版下载安装适合在水深3米内的面积大成规模的鱼塘进行增氧!其**的区别是安装方式不同，沉水PROBURN中文免费版下载安装安装在水下，噪音低、散热好后期维护时比较麻烦!罗茨PROBURN中文免费版下载安装安装在岸边，噪音比沉水PROBURN中文免费版下载安装要大一些，后期维护时比较方便!

　　所以，养殖草鱼的鱼塘主们，需要根据自己的鱼塘面积、密度、水深、供电方式等条件进行选择适合自己的草鱼增氧方式!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!溶解氧含量也比较高一些，同样的造价也比表面增氧的造价要高!

　　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!
