Feed for young bream fish and preparation method thereof

Abstract

The invention discloses feed for young bream fish and a preparation method thereof. The feed is prepared from, by weight, 10-15 parts of bean powder, 8-10 parts of vegetable seed powder, 10-15 parts of wheat starch, 6-12 parts of wheat bran, 6-12 parts of field-snail-meat powder, 4-8 parts of fishbone dust, 5-8 parts of eel grass, 4-6 parts of hydrilla varticillata, 4-6 parts of pondweed, 1-2 parts of duckweed and 12-30 parts of water. The preparation method includes the steps that firstly, water is added to the bean powder, the vegetable seed powder, the wheat starch, the wheat bran, the field-snail-meat powder and the fishbone dust and stirred into a dough state, and a mixture A is obtained; the eel grass, the hydrilla varticillata, the pondweed and the duckweed are cleaned up and crushed into a mud state, and a mixture B is obtained; the mixture A and the mixture B are stirred, thin bars are extruded, baking is conducted, the mixture is made into a powder state, and the feed is obtained. The feed has the advantages that no additive or hormone is added, and the rate of competing for food of bream fish is raised; the eel grass, the hydrilla varticillata, the pondweed and the duckweed are added, growth of bream fish according to natural habits is facilitated, and the bream fish fed with the feed is 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 young 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 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 habits is relatively wide. The various feeds currently on the market basically do not add aquatic plants, especially when the juvenile bream is interrupted.
