Spotted maigre young postlarva feeding promoting agent and method of preparing the same

Abstract

The invention discloses a phagostimulant for fish larvae and juveniles of spotted maigre and a preparation method thereof. The phagostimulant comprises the following compositions in portion by weight: 0.05 to 0.1 portion of dimethyl-beta- propionic acid thetine, 0.1 to 0.2 portion of kanirin, 0.1 to 0.3 portion of glycine trimethylpropyl, 20 to 30 portions of inosinic acid, 25 to 35 portions of clamworm extracting solution, 1 to 5 portions of betaine, 10 to 15 portions of lactamine, 8 to 10 portions of glycin, 26 to 28 portions of internal organ powder of cuttlefish, and 1 to 3 portions of lycopene. The preparation method of the phagostimulant comprises the following steps: raw materials are weighed according to weight portions and are mixed, and then the clamworm extracting solution produced by the mixing extraction of alcohol is added into the mixture. The phagostimulant has the advantages that the phagostimulant has small using amount, apparent effect, steady sources, low price, and simple production technology, can effectively improve survival rate, reduce the waste of baits, can also improve the high temperature resistance and the anti-anoxia ability of fish, strengthen the endurance of the fish to the change of water environment, and can improve the meat quality of breed varieties.

Description

technical field [0001] The invention relates to a feed additive for yellow croaker, in particular to a food attractant for juvenile yellow croaker and a preparation method thereof. Background technique [0002] Yellow croaker has delicious meat and rich nutritional value, and is deeply loved by the masses. However, due to the unbalanced nutrition of fresh and live biological bait, it is easy to carry pathogenic microorganisms, which leads to the decline of seed quality and seriously affects the cultivation of adult fish. Therefore, it is imperative to develop high-efficiency and high-quality artificial pellet feed for yellow croaker. [0003] Food attractant belongs to a kind of non-nutritional additives. Adding appropriate amount in aquatic feed can improve the palatability of feed, improve the quality of bait, and stimulate the senses of smell, vision and taste of aquaculture animals, making them gather around the bait, thus Improve the appetite of aquatic animals, maint...

AI Technical Summary

Problems solved by technology

But there are also many disadvantages, such as the average food intake of animals, low nutritional level and bait utilization rate

A single L-amino acid or its mixture has also been used as a food-attracting additive for fish and shrimp, but its use is limited due to its high cost and high price of top-grade products. Problems to be solved and research and development hotspots

[0004] The existing artificial micro-granule feed has not achieved ideal results in the breeding process of yellow croaker fry. This is mainly due to the fact that compared with the fresh and live biological bait, the existing artificial granule bait has relatively large defects in the food-attracting properties, while the fresh and live biological bait There are chemical and visual stimulant substances in it, such as free amino acids, etc.
