Early spring pond management points

Good management of fish ponds in early spring can promote the early diet of farmed fish, restore constitution, enhance disease resistance and increase survival rate.

Point one: Raise the temperature of fish ponds. In the optimum temperature range, farmed fish will increase their food intake and increase their growth as the water temperature rises. Therefore, the water level of fish ponds in early spring should be controlled at about 1 meter, so that the water temperature of the fish ponds can be raised quickly to facilitate the full play of the fertilizer effect and to encourage the fish to be eaten earlier.

Point 2: Adjust water quality. After the spring, due to the gradual increase of water temperature and temperature, the fish's natural food bait began to breed. If the water quality is found to be acidic, it can be filled with fresh river water at a depth of 20cm. And per acre water area with 20kg ~ 30kg charcoal Quanchiposa. If the water quality is relatively thin, the organic fertilizer may be suitably decomposed to maintain the medium-fertilizer quality. The water body transparency is 30 cm to 40 cm and the ph value is 6.5 to 8.5. Generally, the water per mu can be applied to cattle manure or pig manure 200kg to 300kg each time. Urine 1kg and superphosphate 2kg should be applied. After adding water, the total pool should be spilled after being dissolved 20 to 30 times.

Point 3: Eat in time. When the temperature of fish ponds rises to about 15°C, fishes start to eat small amounts, and sometimes they consume large amounts of food. If they find that the bottom of the water surface is more turbid than the surface of fish ponds, fish activity is frequent, indicating that the fish are in a state of hunger. , you can start the appropriate amount of feeding. The specific practice of eating is to feed once a day or every other day. Each time the amount of feeding is about 1/5 of the amount of feeding in summer and autumn.

Point four: Early prevention. Long-term starvation of fish during the winter can cause stagnant growth and increased disease. Therefore, strengthening the early feeding and management of fish is an effective way to enhance fish disease resistance. The most common fish disease in spring is saprophytic disease, which is caused by fish body injury caused by careless operation in management. Available salt and baking soda mixture, Quanchiposa, when the quality of the two pools of water are two-tenths of a million. In addition, parasites such as trichomonads and slugs also occur from time to time. 0.5 grams of copper sulfate and 0.2 grams of ferrous sulfate (5:2) mixture can be used to cure disease.

Micro Laser Distance Sensor

New product of U85 micro laser distance sensors use highly focused class 2 laser to detect objects or measure distances, and can return a measured value via varieties intface( serial, usb, rs232, rs485, bluetooth etc.). The electronic distance sensor is a very small Laser Distance Sensor, but high resolution up to 1mm and long distance measuring sensor - teachable measuring range of up to 30m. Extremely accurate distance sensing sensors, errors down to ± 1mm. And the mini sensors and measurements support continuous measurement function, great for compact solutions(eg: robots) with the smallest Laser Distance Sensor of the world!
