Plum fish, also known as plum white fish, is a rare thing, and its growing environment is very picky. Plum fish must be produced in the rainy season, and it needs to be rainy, with no sunshine for a long time, or with heavy rain. After migrating and ovulating from the lower reaches of the pool river, plum fish float on the water in groups, and the scene is very spectacular. Only at this time can the tail of plum fish overflow with milk-like secretions, which is the main feature that distinguishes plum fish from other fish, and also the main symbol that plum fish is unique, tender and nutritious.
