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

A kind of immature bream feed and preparation method thereof

Technical field

The present invention relates to technical field of aquaculture, particularly relate to a kind of immature bream feed and preparation method thereof.

Background technology

Bream is Chinese Endemic fish, lives in the attached medium-sized lake of lower Yangtze and family's fishpond for a long time; Because market demand strengthens, single bream has cultivated also on a large scale, and the various bream feeds be derived get more and more, and add various hormone, very easily affect the quality of bream.Bream is herbivorous fishes, fingerling and adult fish are main foodstuff with aquatic vascular plants such as eel grass, hydrilla verticillata, bog pondweeds, also like eating Lu Sheng grass and dish leaf, part of can also ingesting lakebed canebreak and a small amount of zooplankter, therefore feeding habits scope is wider, the all feeds sold in the market there is no and adds pasture and water, is especially interrupted very important bream juvenile fish.

Summary of the invention

The object of the present invention is to provide the equilibrium of a kind of nutrition arrangement, the immature bream feed improving bream survival rate and preparation method thereof.

Object of the present invention is achieved through the following technical solutions: the following compositions comprising following weight parts: bean powder 10-15 part, rapeseed meal 8-10 part, wheaten starch 10 ~ 15 parts, wheat bran 6--12 part, river snail digested tankage 6-12 part, fishbone dust 4-8 part, eel grass 5-8 part, hydrilla verticillata 4-6 part, bog pondweed 4-6 part, duckweed 1-2 part and water 12-30 part;

Described immature bream feed comprises the following compositions of following weight parts: bean powder 12 parts, rapeseed meal 10 parts, wheaten starch 12 parts, wheat bran 8 parts, river snail digested tankage 7 parts, fishbone dust 6 parts, eel grass 6 parts, hydrilla verticillata 5 parts, 2 parts, bog pondweed 5 portions of duckweeds and 22 parts, water;

Preparation method's step is as follows:

(1) first bean powder, rapeseed meal, wheaten starch, wheat bran, river snail digested tankage, fishbone dust are added water and stir into bulk, be under the environment of 22-26 degree, place fermentation 3-5 hour in temperature, obtain mixture A;

(2) eel grass, hydrilla verticillata, bog pondweed, duckweed are cleaned up, be ground into pureed, obtain mixture B;

(3) heated by mixture A and mixture B and stir, temperature controls at 45-60 degree; Mixing time is 1-2 hour; Be extruded into thin rod by extruder, at 100-110 degree temperature, toast 1-2 hour, then breaking into powdery can shape cost product.

Compared with prior art, the present invention has the following advantages:

1, bean powder, rapeseed meal, wheaten starch, wheat bran, river snail digested tankage, fishbone dust are all adopt ecosystem feed not containing any additive and hormone, place grace time fermentation, improve bream and rob food rate after mixing and water adding stirs; 2, add eel grass, hydrilla verticillata, bog pondweed, duckweed be beneficial to the growth of bream natural habit, 3, sliding tender, nutritious by the bream mouthfeel of this forage feed.
