Problems solved by technology

[0002] Due to poor digestion ability and low immune resistance to diseases, aquatic seedlings have higher requirements for bait
The traditional feed for aquatic seedlings is mainly biological baits such as plankton and water earthworms. The bait cannot meet the feeding requirements of aquatic seedlings, which restricts the large-scale and intensive development of aquaculture. Therefore, the development of a seed feed suitable for feeding aquatic seedlings is the general trend of the development of the aquatic industry.
Chinese patent ZL200810028963.7 discloses a "open feed for fish and shrimp fry and its preparation method", which uses fish meal, soybean meal, squid meal, shrimp shell powder and other compound preparations to mix open feed for fish and shrimp fry, thereby solving the biological problem. Unstable bait quality and high risk of disease
However, in the above-mentioned open feed for fish and shrimp fry, because the components are simply mixed together, biological agents and various beneficial elements have not been fully integrated and reacted with the base material of the feed, and cannot form a stable structure. Lost, polluted water quality
Affected by the difference in the dissolution and loss of various preparations in the water body, after the feed pellets enter the water body, the water-soluble nutrients will be quickly lost in the water body, and because the feed pellets will settle rapidly in the water body, the aquatic seedlings will not be good. The ingestion of key vitamins, trace elements, amino acids, etc. is extremely low, which affects the growth and survival of seedlings.

preparation example Construction

[0033] The preparation method of aquatic seed feed comprises the following steps:

[0034] a: Take the above-mentioned components according to the proportioning ratio for subsequent use;

[0035] b: Under normal temperature and pressure, put white fish meal, squid meal, krill meal and α-starch in a blender, stir for 20-40 minutes, then put it in a grinder, and go through primary crushing and superfine crushing to 60-100 head;

[0036] c: Add beer yeast to the mixture in step b, and add a small amount of water to condition and ferment for 1-3 hours, and then put it in an extruder for extruding and granulating;

[0037] d: put the puffed pellets obtained in step c into a pulverizer, and pulverize them to 200-400 mesh;

[0038] e: Add compound trace element premix, compound vitamin premix, compound intestine-protecting and liver-protecting agent, compound enzyme preparation, compound immune enhancer, sodium alginate and 80-120 parts of water to the mixture obtained in step d, a...
