Ecological efficacy of Yongjia Tian fish

Fish farming in rice fields has many advantages. Field fish can eat pests, loosen soil and increase oxygen, keep and increase fertilizer, improve rice growth and development, and promote rice tillering. Generally speaking, fish farmers can increase production by about 10% compared with rice fields without fish. There are many flowers in rice, and the fish in the field get rich feed and grow very fat. Therefore, Nanxi people often say: "Fish and rice are raised in rice fields, and rice increases production and fish harvest."

Yongjia Tian fish has become an ideal ornamental fish species because of its colorful body color. Many Nanxi people transplant field fish into family fish tanks and ponds to beautify and decorate the home environment.
