Embodiment Construction

[0008] The following takes Hippocampus erectus as an example to illustrate the whole process of implementing the method.

[0009] After the line hippocampus hatched, 10 tails were randomly selected to measure body height, trunk height, width at 1 / 2 of trunk height, and wet weight. Randomly get the newly hatched seahorse seedlings and put them into three 25-40 liter aquariums, and put the seedlings at a density of 2 per liter. The newly hatched Artemia nauplii were fed twice a day for 20 days. 3 days, 7 days, 14 days and 20 days after the seedlings were released, 10 tails were randomly selected to measure the body height, trunk height, and the width of 1 / 2 of the trunk height. Observe daily for dead individuals. If there is death, take it out immediately and measure the body height, trunk height, and the width at 1 / 2 of the trunk height. The ratio of width to trunk height (W / H) at 1 / 2 of the trunk height was calculated, and the difference in this index was compared between s...

Abstract

The invention discloses a method for verifying the quality of young hippocampus quickly, relates to a quality verification technique of young hippocampus, and an index and quick verification method for verifying the quality of the young hippocampus are required to be provided. The method for verifying the quality of the young hippocampus quickly is characterized by comprising: taking new hatched young hippocampus randomly and putting in three 25-40 litre aquriums, wherein the density of young hippocampus arrangement is 2 tails per litre; feeding new hatched artemia nauplius twice every day, and feeding for 21 days; taking 5 tails every 3 days randomly before and after young hippocampus arrangement so as to measure the body height, the trunk height, and the width at 1 / 2 of the trunk height; observing every day, removing promptly if new hatched young hippocampus is died, and measuring the body height, the trunk height, and the width at 1 / 2 of the trunk height; calculating the ratio W / H of the width at 1 / 2 of the truck height to the trunk height, and comparing the differences of two indexes between living individuals and died individuals, thus determining the ratio of the width at 1 / 2 of the trunk height of the body index to the trunk height, wherein the ratio represents the index of the quality of the young hippocampus; and measuring the W / H data so as to verify the quality of the young hippocampus. The method for verifying the quality of the young hippocampus quickly is used for verifying the quality of the young hippocampus.

Description

technical field [0001] The invention relates to the quality identification technology of hippocampus seedlings. Background technique [0002] Hippocampus is a traditional Chinese medicine. According to statistics, more than 150 tons of dried medicinal products are used in my country every year. As my country's natural resources are nearly exhausted, most of the seahorses needed in the market are imported, and the price has been increasing year by year. The average price has exceeded 10,000 yuan per catty. Based on the annual import of 150 tons, the value is 3 billion yuan. Because the natural resources of seahorses have been severely damaged, many countries in the world have carried out artificial breeding research in order to restore resources. As early as 1957, my country launched seahorse breeding research. Fifty years later, although seedling technology has developed, large-scale production technology has not yet been broken through. At present, the biggest problem en...
