Problems solved by technology

Its main component DHA is also derived from fish oil, cod liver, fish eggs, etc., but the emulsification technology is stronger than that in China, but the effect is still not ideal
[0009] There are also American products "Algemac3050" and "Algemac2000". 3 High unsaturated fatty acids come from the single Schizochytrium contained in it. Because of the single composition, its nutrition is not comprehensive and balanced

Embodiment 1

[0027] A microalgae bait nutritional enhancer is trial-produced, which is composed of a variety of microalgae with different nutritional components in proportion by weight:

[0028] Schizochytrium 60%, Microcystis arachidonic acid 15%, Spirulina 10%, Haematococcus pluvialis 10% and Cryptidinium crotonii 5%.

[0029] The Schizochytrium sp used is produced by U.S. Martek, 6480 Dobbin Road Columbia, Maryland 21045;

[0030] The arachidonic acid used is micropowder or microencapsulated type, and its particle diameter is 8~12 μ m; Commercially available commodity, trade name trade name: AquaGrow ARA, producer, U.S. ABN (Advanced BioNutrition), company, U.S., Maryland State, Columbia, MD 21045;

[0031] The spirulina used is domestically produced commercial product of Spirulina Platensis, which is crushed into 10 μm particles by us.

[0032] Used Haematococcus pluvialis (Haematococcus pluvialis), commercially available commodity, trade name: NatuRose, U.S. Cyanotech company produc...

Embodiment 2

[0051] The trial-produced microalgae bait nutritional enhancer is compounded by weight ratio of various microalgae containing different nutritional components:

[0052] Schizochytrium 65%, micronized arachidonic acid 15%, Spirulina platensis 10%, Haematococcus pluvialis 10% and Cryptidinium crownii 5%.

[0053] The components were mixed evenly according to the proportion and then pulverized to 5-15 μm; the survival rate was 68.4% and the incidence of albinism was reduced to ≤ 5.3% after trial use in artificial breeding of turbot; the rest were the same as in Example 1.

Embodiment 3

[0055] The proportioning by weight ratio of microalgae bait nutritional enhancer is:

[0056] Schizochytrium 40%, Microcystis arachidonic acid 20%, Spirulina platensis 25%, Haematococcus pluvialis 10% and Cryptidinium crotonii 5%.

[0057] Each component was crushed to ≤10-20 μm and then mixed evenly according to the proportion; the trial was used in artificial breeding of turbot, the survival rate was 69.1%, and the incidence of albinism was reduced to ≤5.7%; the rest were the same as in Example 1.

Abstract

The present invention is one kind of nutrient reinforcing agent for artificial fry raising of marine animal, and relates to the recipe and preparation process of micro algae bait nutrient reinforcing agent. The microalgae bait nutrient reinforcing agent consists of several kinds of micro algae containing different nutritious components and has grain size of 5-20 microns. It contains great amount of DHA, ARA and natural astaxanthin, and can raise the immunity and survival rate of raised marine animal. It can meet the requirement of hatched fries of fishes, shrimps and shells in feed. For example, when the microalgae bait nutrient reinforcing agent is used in raising turbot, it can raise the survival rate and lower the albinism rate greatly.

Description

technical field [0001] The invention belongs to the field of nutritional enhancers for artificial breeding of marine animals, in particular to strengthening rotifers and artemia nauplii in the artificial breeding of seawater larvae, juvenile shrimps and juvenile shellfish, and feeding seawater larvae, juvenile shrimps and juvenile shellfish A microalgae bait nutrient enhancer formula and its preparation method that provide open animal bait and effectively control the albinism of turbot and other flounder flounder. Background technique [0002] Animal products are the main protein source for humans, while aquatic products are more beneficial to human health. Aquatic products, especially those rich in high unsaturated fatty acid docosahexaenoic acid (DHA) are more popular among people. [0003] However, with excessive fishing, environmental pollution, and the gradual depletion of natural resources, there is no doubt that the increase in seafood production will mainly rely on ...
