Preparation method of compound feed for hilsa herrings

Abstract

The present invention discloses a preparation method of a compound feed for hilsa herrings and relates to the technical field of hilsa herring culture. The preparation method comprises the following steps: carthamus tinctorius seed meal, peony cake meal, zophobas atratus, henry steudnera tuber powder, lotus root starch and illite powder are taken; the taken materials are dried; the dried materialsare ground; the ground materials are sieved; the sieved materials are mixed evenly; then an appropriate amount of beer water is added; the materials are mixed evenly; then under a stirring condition,naringenin, pumpkin seed oil, algin and a composite premix are successively added; the materials are mixed evenly; and finally granulating and drying are conducted to obtain a finished product. The compound feed is simple and convenient in preparation, can promote the rapid growth and fish body weight gain of the hilsa herrings, can also improve quality of fish meat, achieves purposes of enablingthe hilsa herring to be fresh, tender and delicious, enables the hilsa herrings to be high in survival rate and is good economic benefits.

Description

technical field

[0001] The invention relates to the technical field of shad culture, in particular to a method for preparing compound feed for shad. Background technique

[0002] Shad is a rare and valuable economic fish in China. It is produced in the lower reaches of the Yangtze River. In 1988, it was listed as the first-level protected species in the list of China's national key protected wild animals. In recent years, due to overfishing, water environment pollution, and water conservancy construction damage to spawning grounds and feeding migration channels, the natural resources of shad have decreased sharply. At present, American shad is mostly imported from the United States and sold as shad in the market. With the society and people’s demand for shad, the scale of shad farming continues to increase. At present, there are very few special feed varieties for shad farming, and other feeds on the market are mostly used. Commodity compound feeds for farmed fish, such as...
