What is the disease of "rotten mouth" and "rotten tail" in breeding true sea bream? How to prevent and cure?

This is a slippery bacterial disease caused by the infection of the body surface of the fish by Radiobacter columnar. If it is found in the cultured red sea bream that there is erosion of the head and end of the snout, hyperemia from the end of the snout to the operculum, white turbidity at the back of the body, especially near the caudal stalk, swelling and vertical scales, and then the caudal fin rot. Prevention and treatment measures are as follows: when the disease occurs in summer, antimicrobial agents should be given immediately. The treatment effect of the disease is best in the early stage of the disease, so early detection is very important.

The occurrence of the disease is closely related to the culture environment, and the sparse stocking density will reduce the occurrence of the disease. During the period of culture, the best way to prevent and cure the disease is to adopt the culture density of fish artificially and regularly to ensure a good breeding environment.
