Problems solved by technology
Whether the feed quality and nutrition are balanced will affect the growth of juvenile fish. If the feed quality is poor, the nutrition provided cannot keep up with the growth rate of juvenile fish, or cannot provide sufficient nutrients for juvenile fish, which will lead to a decline in the resistance of juvenile fish. The ability to resist disease becomes weaker, unable to resist the infection of disease, and the death rate will increase

Abstract
The invention provides feed for wild Schizothorax oconnori fries. The feed is prepared from the following raw materials in parts by weight: 100-150 parts of basic feed, 15-25 parts of traditional Chinese medicine additives, 1-5 parts of rhamnose, 0.5-2.5 parts of squalane and 5-10 parts of hawthorn fruit extract. The feed for wild Schizothorax oconnori fries is high in nutritional value, reasonable in proportion and capable of effectively increasing the survival rate of fries.
Description
technical field [0001] The invention relates to the technical field of fish farming, in particular to a feed for wild Schizothorax seedlings. Background technique [0002] Schizothorax belongs to Cyprinidae, Cyprinidae, Schizothorax subfamily, Schizothorax genus, commonly known as Oushi's bowfish, Paraschithodontia, Heterodon bowfish, and the local name is Bangbangyu. A plateau cold-water fish species unique to my country, distributed in the upper and middle reaches of the Yarlung Zangbo River and its affiliated water bodies. Influenced by religious culture, local Tibetans generally do not eat fish. However, due to the influence of inland food culture and the influx of tourists in recent years, this fish has become a characteristic of the areas along the Yarlung Zangbo River. [0003] In order to protect the wild Schizothorax and at the same time meet the needs of tourists, the breeding industry of Schizothorax has gradually developed. For fish farming, since juvenile fish ...
