Embodiment Construction

[0012] 1. Breeding system

[0013] The gray seahorse seedling breeding system consists of a breeding pond, an inlet and drainage system, an aeration system and a temperature control system. The size of the breeding pond is generally not more than 1000 liters.

[0014] 2. Breeding environment

[0015] During the cultivation of gray seahorse seedlings, the water temperature should be controlled at 25-28 degrees, the salinity should not be lower than 28‰, the light should be 1000lux, and the water should be slightly flowing. Before the body height is 4 cm, the density of juvenile hippocampus can be maintained at 2 per liter, and then gradually decreases to 0.8-1 per liter when the body height is 6 cm.

[0016] Three, bait feeding

[0017] 1. Feeding amount of young hippocampus at different stages

[0018] A. Before the young hippocampus was 4 cm high, the newly hatched artemia or copepods were fed with high unsaturated fatty acids for 24 hours, and the feeding density was 10-1...

Abstract

The invention provides a bait feeding method for baby grey sea horses. The method is conducted under the condition of a cultivation system and a cultivation environment and is characterized in that bait of different specifications is fed according to baby grey sea horse growing requirements in a cultivation period; newly hatched artemia strengthened through highly unsaturated fat acid is fed before the baby grey sea horses are 4 centimeters in height, and feeding density is 10-12 pieces per milliliter; when the baby grey sea horses are 4-4.5 centimeters in height, 4-5-day old artemia is fed, the artemia is strengthened by highly unsaturated fat acid before feeding, the feeding density is 5-6 pieces per milliliter; when the baby grey sea horses are 5.5-6 centimeters in height, 5-7-day old artemia is fed, the artemia is strengthened by highly unsaturated fat acid before feeding, and the feeding density is 5-6 pieces per milliliter; when the baby grey sea horses are more than 6.5 centimeters in height, adult artemia is fed, the artemia is strengthened by highly unsaturated fat acid before feeding, and the feeding density is 3-4 pieces per milliliter; feeding is conducted twice a day according to the bait feeding method, and excrement and dead bait are siphoned four times a day.

Description

technical field [0001] The invention relates to the bait feeding technology for young hippocampus. Background technique [0002] Hippocampus is a traditional Chinese medicine. According to statistics, more than 200 tons of dried medicinal products are used in my country every year. As my country's natural resources are nearly exhausted, most of the hippocampus needed in the market is imported, and the price has been increasing year by year. The average price has exceeded 4,000 yuan per kilogram. Calculated by importing 200 tons per year, the value exceeds 800 million 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 achieved breakthroughs. At present, the biggest problem...
