The use of baits plays a significant role in fishery production and is one of the important means for preventing and curing diseases. In the specific production practice, when baits are used, the farmers do not know how to use the baits, and often the diseased fish do not eat enough medicines, so that the fish’s condition is not relieved, and the pathogenic bacteria (worms) are resistant to the disease. Medicinal, but also a waste of drugs, causing unnecessary losses. In order to improve the effect of bait on fish diseases, the following matters should be noted when feeding baits:
1. The stability of the bait in the water is better to ensure that the bait will not spread soon after entering the water.
2. The amount of feeding baits should be calculated accurately. Calculate the dosage according to the weight of the fish and add the medicine to the feed. The amount of the bait should be within 30 to 40 minutes after feeding.
3. In order to maintain the effective concentration of the drug in fish, it should be administered 2 to 4 times a day.
4. The bait should be sprinkled evenly to ensure that the sick fish eat enough doses. If the baits are not eaten, they will not be able to cure the disease.
5. The bait must be fed continuously for a course of treatment (usually 3 to 5 days or 7 days) as required, or after the fish has stopped dying, continue feeding for 1 to 2 days and do not stop the drug prematurely. Because the drug was stopped prematurely, the pathogens in the fish were not completely destroyed and they were prone to relapse.
6. The day before feeding the bait, the amount of feed should be less than usual, so that the fish populations are hungry, prompting the sick fish to eat more baits the next day. Before feeding the bait, feed a suitable amount of common feed, feed the healthy fish first, and then feed the bait to ensure that the sick fish can eat enough baits. If there are many grass carp in the pool, when other fish are sick, to ensure that the sick fish eat enough bait, you can feed the grass and then feed the bait.
7. Feeding the bait is best done when the storm is small. Otherwise, the bait sprinkled on the water is quickly blown downwind and sinks into the bottom of the water. The sick fish can't eat enough doses. In the case of stormy waves, the number of feedings should be changed from two times a day to four times a day, and the amount of medicine should be increased appropriately.
8. During and immediately after treatment, do not exchange pool water in large quantities, and do not add new water and fishing in large quantities to avoid irritating the fish and aggravate the fish's condition or cause recurrence.
9. At the same time when using internal medicine, it is best to use external drugs to spill and kill pathogens (worms) in the water. This will not only achieve the purpose of treatment, but also improve the water quality.
10. Conditional drainable doses, which can discharge some viruses by draining water, increase the oxygen effect, and make the pool water shallower, narrowing the surface of the water to be administered, and increasing the bait rate. In order to allow each fish to be able to eat baits, it can be cut open with a net, so that the weak fish, floating head fish and bottom fish can even eat baits.
28k Ultrasonic Spot Welding Machine, mainly suitable for automotive sound insulation cotton, mask ear straps, plastic parts and other products that need spot welding, its principle is that the generator generates pressure, and the transducer produces the same frequency of alternating current, converted from piezoelectric ceramics into mechanical vibration, and mechanical vibration produces thermal friction. Friction melts the contact point between the two parts, allowing the part to bond quickly.
The 28k spot welder has a wide range of applications:
Spot welding of thermoplastic thin materials: synthetic chemical fabrics, flat fabrics, knitted fabrics, nylon fabrics, non-woven fabrics, onion cloth, artificial leather, PU, sardines, PS, PVC, TR and various film covering or bonding fabrics.
Spot welding, pressure welding, riveting, marking, sealing, clothing, shoes, handicrafts etc., but also suitable for riveting and welding of auto parts such as bumpers, instrument panels, door panels, etc.
28K Ultrasonic Spot Welding Machine advantages: small size, easy to carry, easy to operate, spot welding machine beautiful appearance.
