Description

Crab feed for molting stage of crabs and preparation method thereof
Technical Field
The invention relates to the technical field of crab feed, in particular to crab feed in the molting stage of crabs and a preparation method thereof.
Background
The crabs are crustaceans, have tender meat quality, delicious taste and high nutritional value, and are deeply popular with people. The whole growth process of the crab can be roughly divided into stages of daphnia larvae, megalops, juvenile crabs, adult crabs, and adult crabs, wherein the shells of the daphnia larvae in the I stage hatched from eggs in the first life are required to be molted (peeled) about 18 times from the last molting, wherein the flea larvae generally need 5 times of molting to become the megalops, the megalops shells are further molted for 1 time to become the juvenile crabs in the I stage, and the juvenile crabs enter the juvenile crab stage after the III stage. The young crab is long before the gonad is mature, is called as the 'juvenile crab', continues to grow, grows with the body shape and has yellow shell color, and is called as the 'yellow crab'. The yellow crab is also called as green crab after the last shelling, the body weight is increased, the gonad is mature, large and old, and the yellow crab is called as adult crab, and the production habit is also called as green crab. At present, the crab feed is not finely divided in crab culture, the conventional juvenile crab feed is difficult to meet the nutritional requirements of juvenile crabs in the molting period, and unreasonable feeding exists, so that the survival rate and the growth speed of the juvenile crabs in the molting period are influenced.
Disclosure of Invention
Based on the technical problems in the background art, the invention provides the crab feed for the molting period of the crabs and the preparation method thereof, which are characterized in that the raw materials are reasonably proportioned, the nutritional requirements of the molting period of the crabs are ensured, the molting process can be accelerated, the smooth molting is ensured, and the survival rate of the molting period is improved.
The invention provides a crab feed for molting stage of crabs, which comprises the following raw materials in parts by weight: 15-20 parts of fish meal, 4-8 parts of silkworm chrysalis powder, 12-18 parts of fermented blood powder, 2-4 parts of yolk powder, 2-4 parts of fish scale powder, 0.05-0.3 part of ecdysone, 5-8 parts of dried potatoes, 0.05-0.2 part of multivitamin, 2-4 parts of kelp powder, 30-35 parts of bean cake powder, 10-16 parts of bran, 1-3 parts of mineral salt, 1-3 parts of scutellaria baicalensis extract and 0.5-2 parts of adhesive.
Preferably, the scutellaria baicalensis extract is prepared as follows: pulverizing Scutellariae radix, extracting with water, filtering, extracting the residue with ethanol under reflux, filtering, mixing the water extract filtrate and ethanol extract filtrate, concentrating under reduced pressure, and drying.
Preferably, the sum of the weight parts of the fish meal, the silkworm chrysalis meal and the fermented blood meal in the raw materials is 35-40 parts.
The invention also provides a preparation method of the crab feed in the molting stage of the crabs, which comprises the following steps: crushing potato, adding fish meal, silkworm chrysalis meal, fermented blood powder, yolk powder, fish scale powder, kelp powder, bean cake powder and bran, stirring and mixing, adding water, stirring, steaming, adding ecdysone, compound vitamins, mineral salts and scutellaria baicalensis extract, and mixing to obtain a mixture; and (4) performing puffing granulation on the mixture to obtain the composite material.
Preferably, steaming is carried out for 2-3 min.
Preferably, the granulated particle size is 3-4 mm.
Has the advantages that: aiming at the growth characteristics of the crabs in the molting period, the invention improves the protein content in the feed, adds the components such as egg yolk powder, fish scale powder, kelp powder and the like, enriches the types of raw materials, has more comprehensive nutrition, improves the immunity in the molting period, and is matched with the scutellaria baicalensis extract to enhance the physique of the crabs in the molting period and improve the disease resistance of the crabs. The proportion of animal protein in the feed is improved, the feeding preference of the crabs to the feed in the molting period is ensured, and the feed intake in the molting period is improved. The invention reasonably mixes the raw materials, ensures the nutritional requirement of the larval crab in the molting period, can accelerate the molting process, ensures the smooth molting, promotes the growth of the larval crab, and improves the survival rate of the larval crab in the molting period.
