Fungal infections in fish can be caused by several factors, including:
- Poor water quality: deteriorating water quality can increase the risk of fungal infections.
- Stress: Stress from aggressive fish in the pond. Too much handling or other factors can weaken a fish’s immune system and make it more susceptible to fungal infections.
- Injuries: Fish that are injured or have other diseases are more likely to develop fungal infections.
- Dead fish: Dead fish or large amounts of decomposing organic material in the pond can contribute to fungal infections.
- Overcrowding: due to overstocking, this can increase the risk of fungal infections. There are higher chances of injuries from other aggressive fish within the stock.
- Temperature: Fungal infections are more likely to occur at lower temperatures. Fluctuation of temperatures can also induce stress in fish, and the fish will be susceptible to infection
