Problems solved by technology

With the development of large-scale farming, the requirements for the production of Macrobrachium rosenbergii seedlings are increasing. The traditionally used biologically active baits, especially Artemia and rotifers, are affected by the natural environment, and the production is unstable.
With the continuous expansion of the production of shrimp seedlings, the demand for bait for artificial seedlings is also increasing, and the biological bait is not only far from meeting the needs of seedling production in terms of output, but also the quality of the biological bait due to environmental pollution has declined. Non-compliance with the requirements for the production of high-quality postlarvae increases the volatility and risk of M. rosenbergii postlarvae production
In addition, the cultivation of biological live bait requires large-scale infrastructure investment and takes up a lot of space, so that the production cost of live bait is too high. At the same time, the production of live bait is relatively complicated, and a large amount of manpower is required to cooperate with the production of Macrobrachium rosenbergii seedlings These are not conducive to the large-scale development of Macrobrachium rosenbergii nursery
When some production units raise Macrobrachium rosenbergii artificially, due to the incomplete research on its nutritional requirements, while feeding some biological bait, they supplement egg yolk, which is very easy to pollute the water body, and the survival rate of larvae is low, which brings more problems to Macrobrachium rosenbergii culture. big economic loss
The above factors have seriously restricted the seed production of Macrobrachium rosenbergii and hindered the further development of Macrobrachium rosenbergii aquaculture

Abstract

The invention discloses a larval macrobrachium rosenbergii micro-pellet feed and a preparation method of the larval macrobrachium rosenbergii micro-pellet feed. Nutritious components of the feed comprise crude protein, crude fat, sugar, crude fibre, ash, salt, phosphorus, water and the like. The feed has the advantages of increasing the survival rate of macrobrachium rosenbergii, accelerating the growth speed of macrobrachium rosenbergii, fast feeding, high stability, convenient use, little environmental pollution and the like. Therefore, healthy development of the industry of larval macrobrachium rosenbergii production and feeding can be promoted.

Description

technical field [0001] The invention relates to the field of aquaculture feed, in particular to a macrobrachium rosenbergii seedling stage microparticle feed and a preparation method thereof. Background technique [0002] Macrobrachium rosenbergii belongs to the genus Macrobrachidae and Macrobrachium taxonomically. It belongs to the same group as freshwater shrimp, brown shell shrimp and Macrobrachium prawn in my country. Native to Southeast Asia, also known as Malaysian prawns, freshwater prawns, long-arm prawns, and money shrimps, it is one of the world's largest tropical freshwater prawns. In 1976, my country introduced Macrobrachium rosenbergii for trial breeding in Guangdong, and it was successful, and has now been promoted to culture all over the country. The individual of this shrimp is big, the body length of the male can reach 40 centimeters, and the weight is 600 grams; the body length of the female is 25 centimeters, and the weight is 200 grams. The meat yield ...
