Description

River crab becomes crab feed

Technical field:

The present invention relates to culture of Chinese mitten crab field of feed, be specifically related to a kind of river crab and become crab feed.

Background technology:

River crab also cries " crab " and " eriocheir sinensis ", and the carapace that head and chest are combined into is square circular, and quality is hard.Front end body has a pair, and side has two to very hard sharp crab tooth.Crab a pair appendage is foremost the foot of a chela, and surface covers with fine hair; 4 pairs of steps are had after the foot of a chela, flat-sided and longer; Abdominal appendage is degenerated.The male and female of river crab can distinguish from its belly: female belly is rounded, and male belly is triangle.River crab is a kind of large-scale crustacean, and health divides 21 joints, and because head and chest respectively save mutual healing, therefore whole body is divided into cephalothorax and belly two part.Become crab back side mass colour, carapace is long 7cm on average, wide 7.5cm.River crab often lives in caves the mud bank of Yu Jiang, river, lakes and marhshes, and nocturnalism, with fish, shrimp, spoil and cereal for food, annual autumn, normal migration was laid eggs to the river mouth gone to sea, and Second Year hatching in 3 ~ May, after developing into young crab, trace back river Fresh & Tender in Texture again, is the food be simply loved by the people.River crab formal name used at school Eriocheir sinensis, the expensive freshwater product of generic name, delicious flavour, nutritious, there is very high economic worth.

At present, along with agalactous universal, be all be main feeding method with mixed feed, cause river crab to reach maturity confusion, some river crab sexal maturity comparatively early, affects the speed of growth in later stage, cause head less, impact sale.

Summary of the invention:

Technical problem to be solved by this invention be to overcome existing technological deficiency provide a kind of various nutriment comprehensively, the river crab of good palatability becomes crab feed.

Technical problem to be solved by this invention adopts following technical scheme to realize:

River crab becomes crab feed, it is characterized in that, be made up of the component of following weight portion: 23-24 part dish Hectometer, 14-16 part rice bran, 5-9 part meat meal tankage, 4-6 part soy meal, 1-2 part monosodium glutamate yeast, 1-2 part mineral matter, 0.5-1 part vitamin, 8-11 part bone meal, 1-2 part phosphatide, 7-8 part fish oil, 5-6 part calcium dihydrogen phosphate, 4-5 part lard, 30-40 part additive, 4-5 part fatty powder.

Further, described additive comprises the component of following weight portion: 8-9 part amethyst, 4-5 part dried human placenta, 11-13 part bighead atractylodes rhizome, 2-3 part Radix Glycyrrhizae, 6-9 part donkey-hide gelatin, 8-10 part saline cistanche, 1-4 part cornu cerve degelatinatum, 10-12 part barrenwort, 6-7 part coloured malt, 0.1-0.2 part isoflavones, 2-3 part rhizome of chuanxiong, the sudden ginseng of 3-4 part, 8-9 part Girald Pteroxygonum Root, 2-4 part black race son grass, 8-9 part fruit of Chinese wolfberry, 3-4 part leek.

River crab becomes a preparation method for crab feed, it is characterized in that, comprises the following steps:

(1) take each raw material of additive by weight, then mixing adds the water of gross mass twice, is heated to seethe with excitement and keeps fluidized state 30 minutes in closed container, after cooling, filters and obtains solution;

(2) feed other each raw material mixing except additive, fish oil, lard pulverized, size is 50-100 order;

(3) in the mixture of step (2), add solution and surplus stock that step (1) obtains, stir, then will carry out granulation, particle size is 0.4-0.8 millimeter, namely obtains Pinnotheres of Chinese Mitten Crabs feed.

The present invention becomes physiology, the growth characteristic of crab according to river crab, the Chinese medical culture traditional in conjunction with China and culture of Chinese mitten crab specialist culture of Chinese mitten crab experience for many years, on the basis of a large amount of experience and test, obtains feed formula of the present invention.Wherein pass through the compatibility between each medicine and work in coordination with, reaching the sexual development degree effectively stablizing river crab, and providing sufficient amino acid and aliphatic acid, improve into the total quality of crab.

The present invention can improve into the head of crab significantly, compares conventional mixed feed, and its average weight improves 20-30%, and becomes the activity degree of crab also to be promoted preferably, has great importance for culture of Chinese mitten crab industry.

Adopt nutrition of the present invention more comprehensive, do not add antibiotic, reduce the medicament residue in river crab body, good palatability, become the coefficient of condition of crab and sexual gland richness all to increase.
