Abstract

The invention provides a micro-particle feed for juvenile coilia nasus and a preparation method thereof. The micro-particle feed for the juvenile coilia nasus comprises the following raw materials: fish oil, fish meal, starch, corn DDGS, yeast powder, puffed soybeans, a mineral premix, a vitamin premix, calcium dihydrogen phosphate, soybean lecithin, chitosan, and digestive enzymes. The preparation method of the micro-particle feed for the juvenile coilia nasus comprises the following steps of embedding cellulase and protease, which are of the same weight, so as to prepare the digestive enzymes; mixing the fish meal, the corn DDGS, the yeast powder and the puffed soybean lecithin so as to obtain a mixture; adding the starch, the mineral premix, the vitamin premix, the calcium dihydrogen phosphate, the soybean lecithin, the chitosan and the digestive enzymes into the mixture; and then, carrying out stirring and crushing so as to obtain the micro-particle feed for the juvenile coilia nasus. The digestive enzymes are added into the micro-particle feed for the juvenile coilia nasus so as to promote digestion and absorption capacities of the juvenile coilia nasus; and thus, the prepared micro-particle feed is capable of improving survival rate of the juvenile coilia nasus, as well as increasing fatness of the juvenile coilia nasus and decreasing feed coefficient.

Description

technical field [0001] The invention belongs to the technical field of aquatic fish feed, and in particular relates to a micro-particle feed for young swordfish and a preparation method thereof. Background technique [0002] Yangtze anchovy (Coilia ectenes Jordan et Seale), commonly known as saury, mackerel, wild hairy fish, plum anchovy, etc., together with Changjiang shad (Tenualosa reevesii) and puffer fish (Takifugu), are also called "three delicacies of the Yangtze River". Sword anchovy is a migratory fish that usually lives in the sea. It enters the river from the sea from February to April every year, and goes up the river for reproductive migration. Spawning populations enter lakes and tributaries along the Yangtze River or carry out spawning activities in the main stream of the Yangtze River. Due to increased pollution in the Yangtze River and overfishing, the output of Yangtze saury has been declining year by year. Moreover, the population and individual miniat...
