For shrimp farming to achieve high yield and high efficiency, whether it is the high water storage and shrimp culture in Hainan, or the intensive mode of Zhuogezhuang in Haiyang, Shandong, it is inseparable from the application of aerators, the most basic and most important condition. Although there are many kinds of aerators, the most practical impeller aerator in shrimp farming is currently used. Its role in shrimp aquaculture can be roughly summarized as follows.
First, the savior of shrimp: When the aerator is working, the impeller stirs the water body, so that the oxygen in the air dissolves into the water and increases the oxygen content in the water. According to the calculation, the oxygen aerator per kilowatt can increase the oxygen to the water by 1.8 per hour. More than kilograms, therefore, when the prawns in the shrimp pond are exposed to oxygen deficiency and floating head phenomenon, aerators are started. The above symptoms can be quickly resolved.
Second, to promote the growth of shrimp, increase production efficiency: aerator impeller mixing water, the shrimp pool can be two to three meters of the lower water and upper water convection, the bottom of the pool of nutrients and pool surface containing high oxygen water uniformity Mixed. Especially in the rainy days, the water layer phenomenon in the pool can be broken and the physical and chemical indicators of the pool water can be consistent. Starting aerators can increase the intensity of photosynthesis, and can promote the rapid growth of plankton in the whole pond, the water quality is more fat, the primary productivity of shrimp ponds is increased, the pool water color is kept normal, shrimp growth speeds up, and shrimp body weight gain is obvious. So that shrimp production increase efficiency.
Third, detoxification function: As we all know, the shrimp pond due to long-term feeding and shrimp body itself new generation of injection products, resulting in black pool bottom, coupled with the proliferation of anaerobic bacteria, so that the bottom of the pool emit ammonia, hydrogen sulfide , carbon monoxide, carbon dioxide and other toxic substances. Through oxygenation, aerobic bacteria multiply, the oxygen in the bottom of the pool increases so that the toxic substances are continuously oxidized and decomposed into non-toxic substances, so that the water quality of the pool water is improved. Even in the high-temperature season in July and August, the bottom of the shrimp pond is not easy. Produce toxic substances to harm the shrimp.
Fourth, the high utilization of bait: due to the high oxygen consumption of shrimp, the use of oxygen machine to increase the oxygen in the water, so that the shrimp to maintain a more prosperous new generation, so that the bait is more fully utilized, the bait coefficient is low The shrimp body grows faster and gains more weight.
Fifth, to the body surface dirt and conducive to pool shrimp distribution: shrimp pond using oxygen aerator, so that the original static pool water, due to the role of aerator impeller, stirring up, forming a flow of water from the static changes, the shrimp body by the water flow Uninterrupted flushing, on the one hand play a cleaning role - to remove dirt on the body surface, on the other hand to make toxic bacteria, parasites, etc. can not easily stain the body surface. The traditional non-inflatable pool shrimps are mostly clustered on the edge of the pool or in a small area of ​​the pool, while the inflated ponds are less widely distributed, have a relatively uniform distribution, and are convenient for feeding, and have a high feeding rate for shrimp.
