Embodiment Construction

[0012] Turbot is a newly introduced high-quality mariculture species, which has developed rapidly, but the technology is not yet perfect. In the seedling production process of turbot, the production of albino seedlings accounts for more than 70% of the total seedlings in recent years. The albino fry are grown into commercial fish, and black and white spots appear on the fish body, and the pigment is extremely uneven, which directly affects the economic sales of the fish. Therefore, improving and restoring the body color of albino turbot has very important practical significance. The present inventors have carried out nutritional research on albino juvenile turbot, and found that the content of different nutrients plays an important role in the development of pigments and the occurrence of related scales in the process of pigmentation. The body color of albino seedlings can be improved and restored to varying degrees through the regulation of nutritional factors.

Description

technical field [0001] The invention belongs to an artificial compound feed for improving the body color of turbot, and relates to a feed preparation method for improving and recovering the body color of juvenile turbot seedlings with pigment albino under aquaculture production conditions. Background technique [0002] Before the present invention was made, there was no relevant report on the research on body color recovery and improvement of turbot seedlings whose body color had albino. There are related research reports on the albinism of the body color of flounder flounder in the world, but they all focus on the reasons for the albinism of the body color of the larvae in the early stage of seed cultivation. For example, Kazuo Tabata (1991), a Japanese scholar at the Hyogo Prefectural Fisheries Experimental Ground, studied the genetic cause of the albino phenomenon of flounder; Takeshi Yamamoto (1992), a Japanese scholar at the Aquaculture Research Institute of the Japanes...
