How to ensure that sick fish eat enough fish medicine
In production practice, internal medicines are often used because diseased fish do not eat enough doses, so that the fish's condition is not only not alleviated, but also promotes pathogenic bacteria (insects) to produce drug resistance, resulting in double losses. To this end, the technical measures for the preparation and feeding of fish medicines are summarized as follows: (1) The bait stability in water is better, such as the stability is not good, the medicine baits will quickly spread out after entering the water, the sick fish will eat Not enough dose. (2) Feed the baits according to the weight of the fish. Calculate the dosage of the bait and add the fish to the diet. The amount of the bait is rather small. Generally within 30-40 minutes after feeding. If not finished for one hour, it means that the amount of bait is too much, resulting in the waste of medicine baits, so that the sick fish can not eat enough doses, but also will affect the next meal. (3) In order to maintain an effective concentration of drug in fish, the bait should be fed 2 to 4 times a day. (4) The oral medicine bait must be continuously fed for one course of treatment as required (generally 3 to 5 days or 7 days) or after the fish is stopped to die, continue feeding for 1 to 2 days, and do not stop the medicine prematurely. If the drug is stopped prematurely, the pathogens in the fish are not completely destroyed and they are prone to relapse. (5) should pay attention to feeding methods: 1 the first day of the insecticide, feeding should be reduced than usual to ensure that the sick fish to eat the bait on the second day. 2 The bait should be spread evenly so that the diseased fish do not eat enough doses of medicine or even baits, which can not achieve the purpose of treatment. 3 Feed the diseased fish first and then feed the baits to ensure that the diseased fish can eat enough baits. For example, when there are many grass carp in the pool, when other fish are sick, to ensure that the sick fish can eat enough baits, they can feed grass fodder and then feed the bait. When feeding the bait, it is best to choose feeding when the storm is small. Otherwise, due to the large waves, the bait sprinkled on the surface of the water will be quickly blown to the downwind, sinking into the bottom of the water, and other fish will not be able to 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 baits should be increased appropriately. Special attention should be paid to: 1 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 stimulating the fish and aggravating the fish's condition or causing recurrence. 2 In the use of internal medicine at the same time, it is best to use external drugs to spill, kill pathogens (worms) in the water, to avoid repeated illnesses.
