Seven Tips for Improving the Effectiveness of Oral Fish Medication

1. Prevention is the key. For fish living in water, disease is hidden and hard to detect. Once dead fish are found, the losses are great, and treating fish diseases is relatively difficult. Therefore, the guiding principle of "prevent disease before it occurs, treat it early when it does, and prioritize prevention over treatment" should be actively implemented, and the concept of focusing on preventive medication should be established. 2. Cleverly combine Chinese and Western medicines. Chinese herbal medicines have a long duration of efficacy in treating fish diseases, few side effects, and low prevention and treatment costs; Western medicines are characterized by rapid efficacy and high cost. Practice has proven that mixing certain Western medicines into effective Chinese herbal medicines can both rapidly improve efficacy and reduce costs.

1. Prevention is the key. For fish living in water, disease is hidden and hard to detect. Once dead fish are found, the losses are great, and treating fish diseases is relatively difficult. Therefore, the guiding principle of "prevent disease before it occurs, treat it early when it does, and prioritize prevention over treatment" should be actively implemented, and the concept of focusing on preventive medication should be established.

2. Cleverly combine Chinese and Western medicines. Chinese herbal medicines have a long duration of efficacy in treating fish diseases, few side effects, and low prevention and treatment costs; Western medicines are characterized by rapid efficacy and high cost. Practice has proven that mixing certain Western medicines into effective Chinese herbal medicines can both rapidly improve efficacy and reduce costs. For example, grinding Chinese herbal medicines such as the "three yellows" (rhubarb, coptis, and phellodendron), water pepper, Andrographis paniculata, and humifuse euphorbia into powder and mixing them into Western medicines such as Huanjie, Kejunwei, and Yubikang improves efficacy by nearly 5-10 times compared with using Chinese herbal medicines alone. Another example: when parasites are found on fish bodies, pine needles, duck-foot leaves, Chinese tallow leaves, eucalyptus leaves, and Budjing leaves can be put into the pond to soak and poison the parasites and bacteria, with lasting effect, low recurrence, and few side effects.

3. Cleverly calculate the fish medication dosage. Based on the average feeding amount in the pond over a period of time (under the premise that the fish are growing normally and have not developed disease, measured as just finishing the food the next day with a slight surplus) multiplied by 20 times, the standing fish stock in the pond can be calculated, and the medication dosage can then be derived. For example: if 300 kg of concentrated feed is routinely fed each day, multiply by 20 times (300x20=6000 kg), meaning the standing fish stock in this pond is about 6000 kg, and the medication dosage is then calculated based on the standing fish stock.

4. Cleverly add phagostimulants. Fish are relatively sensitive to the taste of salt and sugars. To stimulate fish feeding desire, an appropriate amount of phagostimulant can be added to medicated bait. For example, Chinese herbal medicines with strong fragrance such as star anise, clove, and garlic, supplemented with some salt, can be made into a phagostimulant, with an added concentration of 10%-20% being appropriate.

5. Cleverly use binders. The strength of a binder's effect in solidifying the medicine directly affects how long the medicated bait holds together in water. If the medicated bait holds together for a long time, the fish feeding time is extended, the feeding amount increases, and this directly strengthens the prevention and treatment of fish diseases; if the medicated bait holds together for a short time, the fish medicine disperses quickly in water, the fish feeding time is short, the feeding amount is small, and the effect on fish disease prevention and treatment is weakened. This both wastes fish medicine and delays the best opportunity for preventive treatment of disease. Therefore, highly viscous @#@245@#@ powder, cassava flour, glutinous rice flour, etc. should be selected as binders. The binder should account for about 40%-50% of the medicated bait feed.

6. Cleverly select carriers. If plain fish medicine is placed in water, fish rarely eat it. Only by cleverly combining fish medicine with a carrier can efficacy be improved and the best results in preventing and treating fish diseases be achieved. The most suitable carriers are paste-like substances such as corn, soybean, wheat, peanut bran, rice bran, and wheat bran.

7. Cleverly feed the medicated bait. Whether the method of feeding medicated bait is appropriate will directly affect the efficacy of the fish medicine. Practice has proven that before feeding medicated bait, feeding should be stopped for 1 day to let the fish school go hungry. On the second day, when the weather is normal, the prepared medicated bait should be fed only at 9 a.m. (in some cases 4-5 p.m.), which can achieve the purpose of preventing and treating fish diseases.
