Freshwater culture of yellow stickleback.
Pelteobagrus fulvidraco is a bottom fish, which likes to live in clear water or slow flowing water. Pelteobagrus fulvidraco has strong adaptability, tolerance to low-concentration oxygen, the optimum water temperature for growth is 22℃ ~ 27℃, and the growth rate is slow, with a common individual weight of 200 ~ 300 grams and the highest can reach 500 grams. Pelteobagrus fulvidraco is an omnivorous fish that mainly feeds on animals. The newly hatched larvae feed on their own yolk, and the larvae feed on rotifers, cladocera, water worms and other insects, and can be fed with minced fish and mussel meat when cultured artificially. In the adult stage, all kinds of small fish, shrimps and mollusks can be fed, and artificial compound feed can also be fed. It is best to mix live animal bait with some plant bait for feeding. Sexual maturity age of Pelteobagrus fulvidraco: female is 2 years old and male is over 3 years old. In the reproductive period, the male fish has obvious reproductive process behind the anus, while the female fish does not, which is an important symbol to distinguish between male and female. The suitable water temperature for culture is 24℃ ~ 26℃, and each tail contains 4500 ~ 5500 eggs, which are heavy, sticky and orange. When the water temperature of fertilized eggs reaches about 25℃, the larvae hatch in about 72 hours.

At present, the cultured seedlings mainly come from natural waters and can also be artificially propagated. Pelteobagrus fulvidraco has a miscellaneous diet, does not require high water quality and is easy to raise. The results showed that the mixed culture of Pelteobagrus fulvidraco and domestic fish could also effectively control parasitic fish diseases such as anchovy.
