Small bream feed and preparation method thereof

Abstract

The invention discloses small bream feed and a preparation method thereof. The B-level bream feed is prepared from, by weight, 20-30 parts of bean flour, 20-25 parts of rapeseed powder, 10-15 parts of wheat starch, 10-12 parts of wheat bran, 6-12 parts of field-snail-meat powder, 4-8 parts of earthworm powder, 4-8 parts of fishbone dust, 10-15 parts of eel grass, 10-15 parts of hydrilla varticillata, 10-15 parts of pondweed, 5-10 parts of duckweed and 30-50 parts of water. The preparation method includes the following steps that firstly, the bean flour, the rapeseed powder and the like are added with water to be stirred into a cluster, and a mixture A is obtained; eel grass, hydrilla varticillata, pondweed and duckweed are completely washed and smashed into mud, and a mixture B is obtained; the mixture A and the mixture B are stirred and extruded into fine bars, and the fine bars are baked and beat into small particles. The small bream feed has the advantages that no additive or hormone is contained, and the feed scrambling rate of breams is increased; eel grass, hydrilla varticillata, pondweed and duckweed are added, the natural habit growth of the breams is facilitated, and the breams fed with the feed are smooth and tender in taste and rich in nutrition.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a small bream feed and a preparation method thereof. Background technique [0002] Bream is a unique fish in China. It has lived in medium-sized lakes and domestic fish ponds attached to the middle and lower reaches of the Yangtze River for a long time. Due to the increasing market demand, the breeding of a single species of bream has also become large-scale, and various bream feeds derived from it are becoming more and more popular. The more you add, the more various hormones are added, which will easily affect the quality of bream. Bream is a herbivorous fish. Fish species and adults mainly feed on aquatic vascular plants such as bitter grass, Hydra verticillium, and eye vegetables. They also like to eat terrestrial gramineous plants and vegetable leaves, and they can also eat some detritus of lake bottom plants. and a small amount of zooplankton, so the range of feeding h...

Bream is a herbivorous fish. Fish species and adult fish mainly feed on aquatic vascular plants such as bitter grass, hydrilla, and eye vegetables. They also like to eat terrestrial gramineous plants and vegetable leaves, and they can also eat some lake bottom plant debris. and a small amount of zooplankton, so the range of feeding habits is relatively wide. The various feeds currently on the market basically do not add aquatic plants, especially when the juvenile bream to half a catty is very important.
