Problems solved by technology

The invention can not only meet the nutritional requirements for the growth of larvae, but also has the advantages of comprehensive nutrition, good palatability, and good stability in water. The corresponding feeding method can improve the growth and survival rate of juvenile yellow croaker larvae, which is suitable for large-scale promotion and use, but there is still a lot of room for improvement in terms of its average full length and survival rate

preparation example Construction

[0029] The preparation method of above-mentioned yellow croaker juvenile microcapsule feed comprises the following steps:

[0030] (1) Grinding the solid raw materials and additives with an ultrafine pulverizer (WFJ series ultrafine pulverizer, Jiangyin Jinke Pulverizer Machinery Co., Ltd.), the particle size is less than 20 μm;

[0031] (2) Weigh all kinds of feed materials according to the proportion, mix them according to the principle of superimposing a small amount, add a certain proportion of water, mix them fully by hand first, pass them all through a 100-mesh sieve, and then use a three-dimensional multi-directional motion mixer (YH series three-dimensional Multi-directional motion mixer, Changzhou Pu Naier Drying Equipment Co., Ltd.) mixed for 10min;

[0032] (3) Make the mixed raw materials into granules, and use one of the following three methods to make granules: a. Make the mixed raw materials into granules by fluidized bed top spraying method, including the follo...

Abstract

The invention discloses a microcapsule feed for larval and juvenile spotted maigre and a preparation method thereof. The microcapsule feed for larval and juvenile spotted maigre comprises the following raw materials: white fish meal, euphausiid powder, squid powder, fish protein hydrolysate, feeding yeast, alpha-starch, soybean lecithin, papain, fish oil, compound vitamins, composite minerals, anadhesive, an immunopotentiator, a phagostimulant, medium chain triglyceride, sodium houttuybonate, and 5-aminosalicylic acid. The adhesive is sodium alginate; the immunopotentiator is glucan and chitosan; and the phagostimulant is taurine. The microcapsule feed for larval and juvenile spotted maigre is prepared by the following steps of crushing, granulation, coating and grading sieving. Comparedwith the prior art, the feed of the invention can improve the average total length and the survival rate of the larval and juvenile spotted maigre.

Description

【Technical field】 [0001] The invention belongs to the agricultural marine culture technology, and in particular relates to a microcapsule feed for juvenile yellow croaker and a preparation method thereof. 【Background technique】 [0002] Yellow croaker (Nibea albiflora Richardson), commonly known as yellow croaker, belongs to the order Perciformes, Scrotoaceae, and genus croaker. Its body shape is similar to that of large yellow croaker. The sandy mud bottom is relatively shallow in coastal waters, and it feeds on small crustaceans and small fishes. It is mainly distributed in the Northwest Pacific Ocean. It is distributed in the South my country Sea, East China Sea and Yellow Sea in China. The suitable temperature range is 8-33 °C. The suitable salt range is 10-40‰, the optimum growth water temperature is 24-29°C, the spawning water temperature is 24-28°C, and the age of sexual maturity is 2 weeks. Yellow croaker is an important seawater economic croaker in my country. It has...
