High-grade bream feed and preparation method thereof

Abstract

The invention discloses high-grade bream feed and a preparation method thereof. The high-grade bream feed is prepared from, by weight, 20-30 part of soybean powder, 20-25 parts of rapeseed powder, 10-15 parts of wheat starch, 10-12 parts of wheat bran, 10-15 parts of field-snail-meat power, 10-15 parts of earthworm powder, 8-12 parts of fish bone meal, 10-15 parts of eel grass, 10-15 parts of hydrilla verticillata, 10-15 parts of herbs of distinct pondweed, 5-10 parts of duckweed and 30-50 parts of water. The high-grade bream feed has the advantages that the soybean powder, the rapeseed powder, the wheat starch, the wheat bran, the field-snail-meat power, the earthworm powder and the fish bone meal all adopt original ecological feed and do not contain additives and hormone, mixing is conducted, water is added to be stirred to be uniform, the mixture is put for sufficient time for fermentation, and the snatch rate of bream is increased; the eel grass, the hydrilla verticillata, the herbs of distinct pondweed and the duckweed are added, and the natural habitat growth of the bream is facilitated; the bream fed by 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 high-grade 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 feed...

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 weight gain of half a catty to one catty of bream is intermittent.
