Problems solved by technology

[0005] At present, domestic turbot seed cultivation mainly relies on natural baits such as chlorella, rotifers and artemia, which are expensive, cumbersome to operate, and easy to pollute water quality. At the same time, pathogens such as parasites, bacteria and viruses may be introduced. The instability of quality has also brought inconvenience to the cultivation of turbot seed openings, and is not suitable for large-scale production and cultivation of turbot seed
For the feed produced by the prior art, not only the selection of raw materials is not based on the growth and physiological digestion characteristics of turbot seedlings, but also the preparation method is not suitable. The high temperature and high pressure in the preparation process will easily destroy unstable nutritional elements, resulting in feed Nutrient imbalance and reduced utilization efficiency

Abstract

The invention discloses a preparation method of a starter feed for scophthalmus maximus linnaeus fingerlings. The preparation method comprises the following steps of (a), mixing white fish meal with chicken meat powder, beer yeast, soybean meal, flour and a mineral element mixture to obtain a mixture, crushing the mixture, blending the crushed mixture, performing puffing granulation at 100-130 DEG C, and performing drying at the temperature of 50-100 DEG C; (b), mixing egg powder with wet artemia salina and shrimp mat, performing homogenating through a colloid mill, then adding betaine, fish oil, phospholipid and a vitamin mixture, and performing emulsifying and homogenating; and (c), under vacuum, performing vacuum-spraying of emulsifying liquid obtained in the step (b) onto the surfaces of semi-finished products namely baked particles obtained in the step (a), then performing drying, performing cooling, performing crushing, performing screening, performing weighing, and performing packaging. Bioactive components of fresh living feed raw materials and bioactive components of unstable nutrient elements in a feed formula can be effectively maintained, the food calling properties and the utilization efficiency of the feed can be improved, the survival rate of the scophthalmus maximus linnaeus fingerlings can be increased, the growth properties of the scophthalmus maximus linnaeus fingerlings can be improved, pathogens in the feed are reduced, and the water-quality environment of breeding water bodies is improved.

Description

[0001] Technical field: [0002] The invention relates to the field of feed, in particular to a method for preparing an open feed for turbot seedlings. [0003] Background technique: [0004] Turbot (Scophthalmus maximus Linnaeus) is native to the North Atlantic Ocean and its boundary between brackish and fresh waters. It is a rare edible fish and was introduced to my country for breeding in the mid-1990s. At present, the annual breeding output in my country is nearly 50,000 tons, with an output value of nearly 1 billion, and a complete industrial chain of seed breeding, adult fish breeding and processing and export has been formed. In view of the fact that turbot farming has become one of the main marine fish species in northern my country, and its scale is also expanding, the cultivation of turbot seedlings has also become a key issue for the development of the industry. High-quality fish fry that are safe and healthy, with neat specifications and fast growth and maturity ar...
