1. Eye White Candle Disease

Symptoms: This disease is most commonly seen in spring and summer, and the incidence rate is highest in these two seasons. The most obvious symptom of this disease is mainly the appearance of white spots on the eyeball, and then the white spots cover a wider area as time goes on, eventually covering the entire eyeball of the bass. If the condition is serious, it will cause the entire eyeball of the bass to fall off. Eye white candle disease is mainly caused by normally stale bait or a lack of vitamins, so we need to work hard on the feed. Usually, when feeding, the prepared feed should not be too monotonous. The feed must be guaranteed to be diverse and able to supplement nutrition for the bass in all aspects, with emphasis on vitamin supplementation. Replace the water source regularly, keep the water quality clean, and add more vitamin B to the feed.

2. Saprolegniasis

Symptoms: Fish suffering from saprolegniasis will develop fluffy bacterial growth, then the diseased fish will struggle and slowly float to the surface. After a period of time, the symptoms will become more obvious and visible to the naked eye, and their specific manifestations are loss of appetite, refusal to eat feed, and finally a reduction in size, then gradual emaciation until death. Saprolegniasis is mainly caused by infection at the wound after the fish's body is injured. To prevent and treat this disease, change the water frequently, ensure the safety and hygiene of the water source, reduce bacterial substances in the water as much as possible, and spray with malachite green solution.

3. Skin Ulcer Disease

Symptoms: This disease occurs mostly in summer, because the temperature is high in summer and wounds are prone to inflammation. Once infected with this disease, the fish body will lose scales, and the affected area will become congested. Finally, if it worsens severely, it will ulcerate. Many bass become injured during farming due to other factors, causing the wound to be infected by pathogens in the water and leading to disease. Generally, as with the above diseases, loss of appetite will also occur. Finally, the fish will turn white and float to the surface, gradually become thinner, and then die. This disease can be treated by spraying with chloramphenicol.

4. Enteritis Disease

Symptoms: The belly of fish suffering from this disease will become enlarged, producing abdominal distension, and the abdomen becomes very large. Yellow mucus will flow out from the anus, which is easy to notice. This disease must be discovered early and treated early; otherwise, the fish body will stop eating, then gradually become emaciated until death. Most cases are caused by spoiled bait. Furazolidone medicated bait can be added to the feed for treatment.

5. Fish Louse Disease

Symptoms: This disease is mostly caused by fish lice appearing on the fish body, making the fish very restless, with a feeling of localized itching, and there will be a very obvious manifestation, which is that the fish body will rub against the pond wall. Crystalline trichlorfon can be splashed over the whole pond for treatment, causing the fish lice on the fish body to fall off on their own.

The above are the common disease prevention and treatment methods for bass farming. These are the most common bass diseases. There is also an uncommon one called black body disease.
