Embodiment Construction

[0008] The present invention uses Antarctic krill powder as the nutrient material for strengthening Artemia. The total amount of essential amino acids contained in Antarctic krill powder is (221.71±9.14)% (mg / g), and the total amount of amino acids is (458.45±16.34 )% (mg / g).

[0009] The preparation step of the mother liquor of Antarctic krill powder is to use a cross-stirring grinder to ultrafinely pulverize the Antarctic krill powder. Crush to make the particle size of Antarctic krill powder <120μm, and then add 150g of ultra-finely pulverized Antarctic krill powder to 600mL of pure water and stir with a homogenizer. The speed of the homogenizer is 15500-22000rpm , the stirring time is 2min, then stir repeatedly 3 times according to the same method, and then use ultrasonic crushing to dissolve for 20min, so that the particle size of Antarctic krill powder is <50μm, and the mother liquor of Antarctic krill powder is obtained, and the Antarctic krill powder mother liquor is p...

Abstract

The invention discloses a method for fortifying amino acid in an artemia body. According to the method, euphausia superba powders are adopted as nutrition materials for fortifying an artemia. The method is characterized in that a cross stirring and grinding machine is used for smashing the euphausia superba powders into ultra tiny particles and enabling a particle diameter to be less than 120mum, then according to a ratio of adding 150g euphausia superba powders by ultra tiny smashing into 600mL purified water, a homogenizer is used for stirring, then ultrasonic wave is used for breaking and dissolving to enable the particle diameter of the euphausia superba powders to be less than 50mum, mother solution of the euphausia superba powders is prepared, after an overall volume of the mother solution is supplemented to 1L with purified water, the mother solution is placed into a refrigerator with a temperature of 4 DEG C for storage; and the method for fortifying the artemia comprises the following steps that artemia are collected into a bucket with clean sea water, a water temperature is 28 plus or minus 0.5 DEG C, a salinity is 28 plus or minus 1, inflation is carried out continuously, the bucket is subjected to natural illumination, a density of the artemia is 45 plus or minus 3 inds / mL, then the prepared euphausia superba mother solution is added into the bucket, a final density of used euphausia superba powders is 150 mg / L, and the fortifying time is 6-18 hours.

Description

technical field [0001] The invention belongs to the nutrient strengthening technology of aquatic organism bait, in particular to the method of nutrient strengthening amino acid in Artemia. Background technique [0002] Artemia sp., also known as saltwater Artemia sp., Artemia sp., belongs to the phylum Arthropoda, Crustacea, Branchiopoda, Anocaria, Salt Artemia family, is a wide-temperate species with worldwide distribution. Small crustaceans resistant to high salt are also the main biological bait for sea larvae, juveniles, young fish, shrimp and crab seedlings and precious ornamental aquarium animals. Amino acid is a general term for a class of organic compounds containing amino and carboxyl groups. It is an important structure and energy substance to promote the rapid growth of marine fish larvae. Amino acids can not only promote the digestion and growth of aquatic animals, but also improve the body's immunity and anti-stress ability Wait. According to reports, arginine...
