Description

Goldfish fry starter feed and preparation method thereof
Technical Field
The invention relates to the field of preparation of goldfish fry starter feed, and particularly relates to goldfish fry starter feed and a preparation method thereof.
Background
Goldfish is the essence of China, is famous for the world with beautiful posture, rich color and elegant shape, and is popular with people. Has profound cultural connotation and bottom implication, and is one of the traditional cultural heritages of China. The data show that the annual output value of Chinese goldfish is 5 hundred million yuan. The high-quality goldfish can be exported to developed countries such as Europe, America, Japan and the like, plays a very good role in international cultural communication, and can also obtain a very high value. Therefore, the culture and breeding of the high-quality goldfish become the pursuit target of the majority of cultivation enthusiasts.
Because the digestive system of the fish in the early stage is not developed completely, the nutrition required by the development of the juvenile fish is completely provided by the yolk sac; as the yolk sac of the fry becomes smaller, the oral cavity and the anus are gradually communicated with the outside, and a small amount of food intake is started. Researches prove that the large-scale fry breeding effect can be effectively improved by selecting the initial feed with comprehensive nutrition and good palatability at the initial stage of fish initial breeding, so that the initial feed is the most main factor influencing the survival rate and the growth rate fluctuation of the fish at the initial stage of hatching.
The traditional fry culture opening relies on biological baits (such as rotifers, zooplankton, artemia and the like) as early-stage opening baits for fishes. The yield of the biological bait is low, the way of obtaining the biological bait is to fish and concentrate the biological bait in the field water, and the biological bait sold in the aquarium market is also sold after being fished by people, so the price is very high. Biological baits such as hatchable artemia nauplii and cultured rotifers eaten at the later stage of fries cannot provide sufficient nutrition for the growth of fries due to lack of nutritional ingredients such as highly unsaturated fatty acid and the like. In addition, the biological baits live in sewage and foul water ditches containing a large amount of organic matters, carry a large amount of bacteria or viruses, and are easy to cause symptoms such as gill turning, mouth rotting, saprolegniasis and enteritis in the cultivation process of goldfish fries, so that a large amount of death occurs seriously. These factors all seriously affect the survival rate and the growth rate of goldfish fries, thereby restricting the planning, industrial breeding and production of high-quality goldfish fries.
Disclosure of Invention
Aiming at the problems, the invention provides a goldfish fry starter feed and a preparation method thereof. According to the self nutritional requirements of the goldfish fries, raw materials are carefully selected, and a formula raw material proportion combination and a special refined processing scheme are utilized, so that the goldfish fry starter feed which is comprehensive in nutritional value, convenient to absorb by a fry digestion system and in line with the rapid and healthy growth of the goldfish fries is provided for goldfish fry starter feed.
