Oxygenation method in aquaculture:

在養(yǎng)殖業(yè)中，幾乎所有養(yǎng)殖戶都會遇到水池缺氧的情況，缺氧在夏季高溫期幾乎是正常的。下面介紹幾種常用的快速增氧方法。

In the aquaculture industry, almost all farmers will encounter hypoxia in the pool, which is almost normal in the high temperature period in summer. The following describes several common rapid oxygenation methods.

1、加入增氧劑。主要是向養(yǎng)殖水域投放化學制劑，遇水后，水中發(fā)生化學作用，釋放氧氣，提高水體溶解氧含量?；瘜W增氧劑一般是過硫酸氫鉀、過氧碳酸鈉、過氧化鈣之中的一種，增氧是其主要和基本功效。使用化學增氧劑主要是向全池噴灑或局部噴灑，具體使用量取決于品種和使用情況，養(yǎng)殖戶應根據(jù)情況決定。

1. Add oxygen enhancer. It is mainly to put chemical agents into the aquaculture water area. After encountering water, chemical action will take place in the water to release oxygen and improve the content of dissolved oxygen in the water. Chemical oxygenant is generally one of potassium bisulfate, sodium peroxycarbonate and calcium peroxide. Oxygenation is its main and basic effect. The use of chemical oxygen enhancers is mainly to spray the whole pool or locally. The specific amount depends on the variety and use situation, and the farmers should decide according to the situation.

化學增氧劑的利弊。優(yōu)點一般用于出現(xiàn)通電困難和急性浮頭時的池塘，使用化學增氧劑減少壓力，提高藥效，增氧效果快。使用殺蟲等魚藥時，噴灑化學增氧劑，有助于魚蝦蟹等水生動物的身體恢復。缺點是，使用量大，用工量大，費用高，只能在救助魚浮頭時使用，養(yǎng)殖期間要經(jīng)常配備，也因放置不當而降低效果?；瘜W增氧劑使用太多，容易對魚蝦蟹造成傷害。

Advantages and disadvantages of chemical oxygenants. The advantages are generally used in ponds with difficulty in energizing and acute floating head. Chemical oxygenants are used to reduce pressure, improve efficacy and have fast oxygenation effect. When using fish insecticides such as insecticides, spray chemical oxygenants to help the body recovery of aquatic animals such as fish, shrimp and crab. The disadvantage is that it is used in a large amount, with a large amount of labor and high cost. It can only be used when rescuing fish floating heads. It should be equipped frequently during breeding, and the effect will be reduced due to improper placement. Too much chemical oxygen enhancer is easy to cause harm to fish, shrimp and crab.

2、使用增氧劑增氧。主要通過漁業(yè)機器向養(yǎng)殖水域提供含量高的水域，或水域和空氣更好的接觸，不斷向水體補充氧氣的方式增加水域的溶解氧。機械增氧方式主要是泵、增氧機、鼓風機、微孔管增氧等。

2. Oxygenate with oxygenant. The dissolved oxygen in the aquaculture water area is increased mainly by providing high-content water area to the aquaculture water area through fishery machinery, or better contact between the water area and the air, and constantly replenishing oxygen to the water body. Mechanical oxygenation methods mainly include pumps, aerators, blowers, microporous tubes, etc.

機械氧氣增加的利弊：增氧泵增氧是在養(yǎng)殖水域加水的同時，通過增氧起到機械多效的作用。水產(chǎn)增氧機除增氧外，還具有攪水、曝氣功效，提高池塘初級生產(chǎn)力。微管增氧與傳統(tǒng)葉輪、水車式增氧相比，具有多點均勻增氧、、節(jié)水的功效。缺點，只有電力順暢才能使用，例如，在遠離工業(yè)用電的地區(qū)，安裝電路的費用很高。機器常年暴露在空氣中，容易刮風下雨，長期接觸水面，造成機械損傷，因此需要定期維修，維修費用高。增氧機增氧限制在一定面積內(nèi)，屬于單點增氧，池底溶解氧含量低，機器運行噪音大，對水產(chǎn)動物生長和碰傷水產(chǎn)動物，特別是蝦蟹甲殼類動物在蛻皮時或病害影響高峰時有很大影響。

Advantages and disadvantages of mechanical oxygen increase: the oxygenation of the oxygenation pump plays a mechanical multi effect through oxygenation while adding water to the aquaculture water area. In addition to oxygenation, the aquatic aerator also has the effects of stirring water and aeration to improve the primary productivity of the pond. Compared with traditional impeller and waterwheel oxygenation, microtubule oxygenation has the effects of multi-point uniform oxygenation, energy saving and water saving. The disadvantage is that it can only be used if the power is smooth. For example, in areas far away from industrial power, the cost of installing circuits is very high. The machine is exposed to the air all year round, which is prone to wind and rain. It is in contact with the water surface for a long time, resulting in mechanical damage. Therefore, it needs regular maintenance, and the maintenance cost is high. The oxygenation of the aerator is limited to a certain area, which belongs to single point oxygenation. The dissolved oxygen content at the bottom of the pool is low, and the operation noise of the machine is loud, which has a great impact on the growth and bruise of aquatic animals, especially shrimp, crab and crustaceans in molting or at the peak of disease impact.
