Excellent whitebait breeding method

Abstract

The invention discloses an excellent whitebait breeding method. The method comprises the following steps: (1), selection of parents; (2), building of a pond for the parents; (3), raising of the parents; (4), breeding of the parents; (5), artificial fertilization; (6), hatching of fertilized eggs; (7), breeding of whitebait fries. The problem of degradation of descendant varieties is solved through selection of whitebait in two areas far away from each other as the parents; the parents are bred under various environment conditions, the parents with poorer physical conditions are eliminated, and the overall quality of the fertilized eggs is improved; the bred whitebait fries are further bred, and the overall quality of the whitebait fries is improved to larger extent; meanwhile, by means of ecological plasticity of the whitebait fries, the living capacity of the whitebait fries is enhanced when environmental factors such as water temperature, the content of oxygen in water, the potential of hydrogen of water and the like change, the growth speed and the meat quality of the whitebait are both improved in proper environment, and the growth and quality stability of the bred fries is high.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a high-quality breeding method for whitebait. Background technique [0002] Whitebait is one of the famous and precious aquatic products in my country. It is known as a treasure on the table and has a long-standing reputation at home and abroad. It has become a hot spot in aquaculture in recent years. The current conventional whitebait breeding methods have the following defects: (1) The selected whitebait parents grow in a relatively close location, and the species degenerates after multiple breedings; In a healthy state, after hybridization, some seedlings will have poor physique and uneven quality; (3) Although some seedlings can survive in the early stage, they will die easily when they encounter environmental fluctuations in the later stage, and they do not have good economic conditions. Value, loss of previous feeding costs. Contents of the invention [0003] In o...
