Abstract

The invention discloses a traditional Chinese medicine additive of a compound feed for micropterus salmoides fry. The traditional Chinese medicine additive comprises the following components in parts by weight: 2-4 parts of polygonum multiflorum, 5-10 parts of dandelion, 4-6 parts of rhizoma alismatis, 3-5 parts of fructus psoraleae, 1-2 parts of ferrous sulfate, 2-4 parts of copper sulfate, 4-6 parts of medical stones and 65-75 parts of rice hull powder. By adding the Chinese herbal medicine such as polygonum multiflorum, dandelion, rhizoma alismatis, fructus psoraleae and the like which are scientifically matched with mineral salt, the skeletal development of the micropterus salmoides fry is accelerated, and the growing speed of the micropterus salmoides fry can be obviously improved. The growth of the micropterus salmoides fry is not significantly different from that of the micropterus salmoides fry by feeding frozen fish and the fry evenness and the survival rate are superior to those by feeding frozen fish.

Description

technical field [0001] The invention relates to the field of perch breeding, in particular to a compound feed for California perch fry. Background technique [0002] California perch (Micropterus salmides), also known as largemouth bass, belongs to the order Perciformes, the family Sunfish, and the genus Black Perch. It is a high-quality freshwater carnivorous fish native to California, USA. Introduced to my country in the early 1980s, it has the advantages of fast growth, relatively few diseases, low temperature resistance, easy fishing, less thorns, delicious taste, and rich nutrition. It is known as the "yellow croaker" in freshwater and is a rare freshwater fish one of the classes. [0003] California perch has strong adaptability and is a wide-temperate carnivorous fish. It can survive the winter naturally in the south and north of my country, and can be cultured in most provinces of my country. In recent years, the breeding volume of California perch in Guangdong Prov...
