High-calcium feed for summer fingerlings

Abstract

The invention provides high-calcium feed for summer fingerlings which comprises the following components in parts by weight: 30-35 parts of glutinous rice flour, 20-25 parts of haw jam, 10-15 parts of yeast powder, 10-15 parts of alfalfa meal, 10-15 parts of kelp powder and 1-3 parts of pepper. The feed refers to granules prepared by uniformly mixing the components according to a formula ratio and granulating, the feed preparation can be realized by utilizing a conventional granulation method in the technical field, and the particle size of the feed granules is 1-2mm. The particle size is particularly applicable to the body shape of the summer fingerlings, the condition that the feed cannot be eaten by the fish due to extremely large granules is avoided, and due to the size, the condition that the feed granules are dispersed in a water body so as to influence a clarified state of the water body is avoided. The feed prepared by the invention has an outstanding effect of promoting weight gain of the summer fingerlings and provides assistance in inhibiting diseases and improving the survival rate. The feed disclosed by the invention achieves obvious technical progress due to the innovative technology and has extremely high popularization potential.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to a high-calcium feed for summer flower fish species. Background technique [0002] After a period of cultivation, the fry will be called summer flowers when their body length reaches 2.6-3.3 centimeters. Since the fish fry were cultivated under high-density conditions at the beginning, after the summer flowering, as the fish body grows up, the activity space is also required to gradually increase, and the water quality and nutritional conditions of the original pond can no longer meet the needs of the fish body. Therefore, it is necessary to raise the summer flower fish species in separate ponds and make preparations for going out of the pond. Otherwise, not only will the growth rate be slowed down, but also fish diseases will occur, which will directly affect the ponding rate and survival rate. [0003] Summer flower fish is different from adult fish in that it has poor to...
