The Chinese sturgeon is a carnivorous fish that mainly eats animal food. In natural waters, juvenile fish mainly feed on benthic invertebrates, mainly water fleas, but also small shrimps, crabs, and clams; adult sturgeons mainly feed on benthic fish in the ocean. During reproductive migration, parent sturgeons generally stop eating. Under artificial breeding conditions, Chinese sturgeon larvae begin to eat when their total length is 3.05±0.07 cm, mainly eating aquatic oligochaetes, chironomid larvae, cladocerans and copepods; young sturgeons feed on aquatic oligochaetes (water silkworms) Earthworms, vibrating earthworms, caudal gill earthworms, etc.), cladocerans (Daphnia flea, Daphnia longiformis, etc.), aquatic insect larvae (chironomid larvae) and shrimps are the main food; adult sturgeons mainly eat various feed fish pieces (Such as crucian carp, tilapia, silver carp, grass carp, etc.). Since 1989, the Chinese Sturgeon Research Institute has carried out scientific research on Chinese sturgeon compound feed, opening up a broad source of feed for large-scale artificial breeding of Chinese sturgeon. Chinese sturgeons of various sizes can eat compound feed. Judging from the current breeding effects of compound feeds, the opening feed for young sturgeons is better when fed with natural feed (water earthworms) than by feeding artificial compound feeds; while for young sturgeons and adult sturgeons, feeding with compound feeds is better. Feed is better than feeding natural bait (water earthworms) for breeding.
