The improvements to the pond are mainly reflected in the following: When oxygen levels in the fish pond drop, activating the aerator can prevent fish and shrimp from exhibiting “floating heads.” On sunny days, when dissolved oxygen levels are high in the upper water layer, enhanced water convection accelerates the mixing of water layers, increasing dissolved oxygen in the lower layers. This promotes rapid growth of fish and shrimp, reduces the feed conversion ratio, facilitates the oxidation and decomposition of organic matter, and helps minimize disease outbreaks. Moreover, the circulating flow of water also stimulates the reproduction and growth of plankton, thereby boosting the pond’s primary productivity.

The improvements to the pond are mainly reflected in: When the fish pond experiences oxygen deficiency, turning on the aerator can prevent fish and shrimp from "floating their heads." On sunny days, when dissolved oxygen levels are high in the upper layer of the water, enhanced water convection can increase dissolved oxygen in the lower layers, promoting rapid growth of fish and shrimp, reducing the feed coefficient, accelerating the oxidation and decomposition of organic matter, and thereby decreasing the incidence of disease. Moreover, the circulating flow of water also stimulates the reproduction and growth of plankton, boosting the pond's primary productivity.

   Waterwheel aerator Its function not only increases the oxygenation of water bodies but also effectively enhances the primary productivity and self-purification capacity of ponds, thereby improving water quality and the ecological environment. Although the water circulation flow it generates may not be suitable for the living habits of certain aquaculture species such as eels, it plays a significant role in promoting the health and rapid growth of fish and shrimp.

  1. Each night, the feed must be served clean and free of excess leftovers to prevent issues such as feed clumping and rodent damage to the netting.

  2. After the main motor of the feeding machine rotates for 3-5 seconds, the auxiliary motor starts working and drives the feeding hopper to vibrate and discharge material, indicating that the feeding machine is operating normally. If the main motor fails to start, immediately disconnect the power supply and identify the cause. Check whether the discharge port is blocked or obstructed by incoming material; clean it promptly to ensure smooth operation of both the motor and the throwing disc. Also, inspect the capacitor for damage and replace it promptly if any damage is found, to prevent further damage to the main unit.

  3. The feed inlet, feeding port, and feeding vibration box should be cleaned once a month to prevent dust from causing feed material to clump. They should also be cleaned and maintained every 6 months, during which time you should check whether the wires are loose or damaged. If any issues are found, tighten them or wrap them with insulating tape.

  4. Inspect the oil-lubricated bearings: Ensure smooth operation if they are lubricated with oil; check whether the key pins have come loose and whether the locking screws on the shaft are loose—tighten them if necessary or perform a thorough inspection. Confirm that both the main and auxiliary motors are functioning properly.

  5. The capacitor is a key component that helps the motor start. To determine whether a capacitor is working properly, insert its two leads into a power outlet, then remove them and touch them briefly. If you see a spark, it means the capacitor is discharging normally and functioning correctly.

  6. After entering the fasting period, the feeding machine must be disabled. The feeding machine manufacturer recommends thoroughly cleaning the feeding machine, disconnecting its power supply, and prohibiting outdoor storage near the pond. Take protective measures by covering it or moving it to a warehouse for storage.

   The waterwheel aerator can... Increasing dissolved oxygen in the lower layer of water bodies promotes the rapid growth of fish and shrimp, reduces the bait coefficient, facilitates the oxidation and decomposition of organic matter, and helps decrease the incidence of diseases.

The relationship between water convection and dissolved oxygen levels in aquatic bodies: The introduction of an aeration device can effectively regulate dissolved oxygen levels.

Although fish floating to the surface can be caused by a variety of factors, in addition to excessive stocking density, overloading the total fish biomass, and poor water quality, the convective properties of water are also a major factor that cannot be overlooked. Simply put, when water temperature is low, its specific gravity (or density) increases, causing it to sink; conversely, when water temperature is high, its specific gravity (or density) decreases, making it float upward. Understanding and mastering the principles of water convection will greatly facilitate the smooth operation of aquaculture. On warm days, after being heated by the sun during the day, the warmer, lighter water tends to stay on top. As the sun sets and the air temperature begins to drop, the upper layer of water cools down, increasing its density, and gradually starts to sink. If the nighttime temperature remains relatively high, the water cools down slowly, and the upper layer won't reach the bottom of the pond until early morning. This is one of the main reasons why oxygen levels tend to drop sharply from late night into early morning on hot days. However, if a heavy rainstorm occurs in the evening, the situation changes dramatically. The cold, heavy rainwater quickly sinks to the bottom of the pond, stirring up sediment, leftover feed, fecal waste, biological residues, and other organic matter from the pond bottom and bringing them into the middle and upper layers of the water. These harmful organic substances rapidly deplete the dissolved oxygen in the water. Before dawn even breaks, the dissolved oxygen in the water may be completely used up, leaving the fish vulnerable to oxygen depletion and causing them to float to the surface—a phenomenon known as "floating and surfacing." Therefore, sudden heavy rainfall in the evening or at night can also lead to oxygen depletion and fish floating to the surface.
