Anti-stress preparation for reducing fry transportation loss as well as preparation process and use method thereof

Abstract

The invention relates to an anti-stress preparation for reducing fry transportation loss, as well as a preparation process and a use method thereof. The anti-stress preparation comprises vitamin C, taurine, r-aminobutyric acid and a traditional Chinese medicine extract, and is characterized by also comprising N-carbamylglutamic acid, wherein the weight of vitamin C is 20-30 parts, the weight of taurine is 25-40 parts, the weight of N-carbamylglutamic acid is 25-40 parts, the weight of r-aminobutyric acid is 10-15 parts, the weight of the traditional Chinese medicine extract is 5 parts, and theinsuffient rest parts are supplemented by anhydrous dextrose. Glucose has the effect of supplementing energy, so that the fries are kept vigorous. According to the anti-stress preparation, the knowningredients with relatively strong anti-stress effect on adult fish are matched with the traditional Chinese medicine extract (even glucose is added) to form a powdery compound, and the powdery compound is used as a culture water body for long-distance transportation of fish fries after being mixed with water, so that the survival rate of the fish fries subjected to oxygenated transportation within 48 hours can be increased by 20% or above.

Description

technical field [0001] The invention relates to an anti-stress preparation, in particular to an anti-stress preparation for reducing fry transportation loss and its preparation process and application method. Background technique [0002] Fry transportation is a key link in the breeding process. The fry are expensive, the transportation time is too long, improper operation and other reasons can easily lead to excessive loss of fry and low survival rate in ponds. During the fry transportation process, anti-stress substances are added to the transport water body to comprehensively improve the anti-stress ability of the fry against changes in temperature, air pressure, ammonia nitrogen, and dissolved oxygen, thereby improving the survival rate of transportation. [0003] A variety of studies have found that vitamin C, taurine, r-aminobutyric acid, etc. have strong anti-stress effects, but most of them add additives to the feed for continuous feeding. To improve the anti-stress...
