What are the prevention and control methods for enteritis in yellow catfish?
(1) Pathogen: Aeromonas punctata. (2) Symptoms: The diseased fish has a distended abdomen and red, swollen anus; when the abdomen is gently pressed, yellow mucus flows from the anus, and the diseased fish swims alone away from the group.

Control Methods for Ichthyophthirius multifiliis Disease in Farmed Yellow Catfish
(1) Pathogen: Ichthyophthirius multifiliis. (2) Symptoms: On the skin, fins and gills of diseased fish, small white cyst-like spots can be seen with the naked eye; in severe cases, the body surface appears to be covered with a white film. Diseased fish respond sluggishly or float at the water surface. Due to bacterial infection at the affected sites, the fish body surface becomes inflamed, or locally necrotic, scales fall off, fins split diagonally, gill epithelium proliferates, and death occurs due to impaired movement and difficulty breathing in the gill area.
