CATDOLL : CATDOLL: What medicines are needed to raise ornamental fish?

1. Three essential medicines for fish farming

1. Yellow powder. Yellow powder is a commonly used drug for treating fish diseases. It is also called furazolidone. It is a bright yellow crystalline powder. Its main function is to treat bacterial diseases and interfere with the metabolism of bacteria. Therefore, it can achieve the function of antibacterial or bactericidal. It should be noted that when yellow powder is dissolved in water, it will reduce the dissolved oxygen content in the water. Therefore, after using yellow powder, oxygen should be increased to prevent fish from hypoxia. Try to let sick fish take a medicated bath alone. High concentration and long-term use are not recommended.

Second, methylene blue. As mentioned above, I would like to add that methylene blue is a biological dye and medical disinfectant. A small amount of contact with the skin is not harmful, but a large amount of contact with the skin or mouth will cause discomfort. It is mainly used to treat white spot disease, saprolegniasis, tail rot, oblique tube worms, and trichodina. Among them, the treatment effect of saprolegniasis is the best.

Third, malachite green is an all-purpose drug. It has a strong therapeutic effect on bacteria, fungi, and parasites. Malachite green does not exist in the natural environment. It is synthesized artificially. The color is very beautiful, just like a kind of jade called malachite. However, it is not without disadvantages. It is highly toxic. Long-term or overdose use may cause cancer. In the past, as long as there were sick fish in the fishery, someone would put some malachite green in the fish and the fish would immediately jump around. However, due to its strong toxicity, the drug will remain in the fish's body and cause certain damage to the fish's body functions. Therefore, it is not recommended to use it unless it is absolutely necessary.

2. What medicines are generally needed for fish farming?

01) Bleach: The concentration of bleach in the tank is ≤1.5mg/L; the concentration of the bleaching agent is 5mg/L, and the time is ≤15 minutes; the concentration of the bleaching agent is 10mg/L, and the time is 8 to 10 minutes.

02) Copper sulfate. Concentration in the tank ≤ 1.2 mg/L; bath concentration 8 mg/L, time 15-20 minutes; bath concentration 15 mg/L, time ≤ 10 minutes.

03) Trichlorfon (90%). Tank concentration ≤ 0.5 mg/L; bath concentration 10 mg/L, duration ≤ 24 hours (depending on tolerance); bath concentration 50 mg/L, duration 20 to 40 minutes.

04) Salt. The concentration of salt in the tank is ≤0.1%; the concentration of salt in the bath is 3%, and the time is 10 minutes; the concentration of salt in the bath is 15%, and the time is ≤5 minutes.

05) Potassium permanganate. The concentration of potassium permanganate in the tank is ≤5mg/L (adding 0.7% salt will have a better effect, and can treat fish diseases such as water mold, protozoa, and crustaceans); the concentration of the drug bath is 10mg/L, the water temperature is 21-30℃, and the bath time is 1-1.5 hours (killing new mullets, anchor mullets, and sporozoa on the body surface); the concentration of the drug bath is 20mg/L, and the soaking time is 15-30 minutes (to treat ringworms and three-generation worms, and it is also effective for fish bean worms, wheel worms, and oblique tube worms).

06) Ampicillin. It is a modified penicillin with broad-spectrum antibacterial properties. It can treat bacterial sepsis, bacterial enteritis, printing disease, etc. in fish. The concentration of the drug bath is 30-50 mg/L, the time is 2 hours, for 3 consecutive days, 1-2 times a day. The prepared drug solution cannot be used every other day. For medium-sized fish that are unable to eat, fin intramuscular injection can be performed, the dose is 25-50 mg/kg body weight, once a day, for three consecutive days. For pharmaceutical bait treatment, 10 mg/kg body weight, feed twice a day (at least 8 hours apart), for 4-5 consecutive days.

07) Amoxicillin. It has the same properties as ampicillin and is also a broad-spectrum antibacterial drug, but it is more effective against Gram-negative bacteria. It is used to treat bacterial gill rot, white skin disease, white head and white mouth disease, bacterial septicemia, bacterial enteritis, printing disease, vertical scale disease, etc. The bath concentration is 25-40 mg/L, the time is 1-2 hours, and the bath is once a day for three consecutive days. Large fish and medium fish that can no longer eat can be injected into the fin muscle at a dose of 25-50 mg/kg body weight, once a day, for three consecutive days. It can also be treated with medicinal bait, 10 mg/kg body weight, twice a day, for 4-5 consecutive days.

3. What are the commonly used drugs for fish farming? Five essential drugs for fish farming

Introduction to commonly used drugs for fish farming
