Embodiment Construction

[0008] The whole process of implementing this method is illustrated below with an example.

[0009] 1. Breeding system

[0010] The gray seahorse broodstock 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 400-500 liters.

[0011] 2. Breeding environment

[0012] During the cultivation of gray seahorse seedlings, the water temperature should be controlled at 24-27 °C, the salinity should not be lower than 28‰, the light should be 1000 lux, the water depth should be 70 cm, and the water should be slightly flowing.

[0013] Three, bait feeding

[0014] Highly unsaturated fatty acids for hippocampus feeding, such as commercially available Suo Suo brand Adult artemia fortified with high unsaturated fatty acids for 24 hours, the feeding density of artemia is 0.5-1 / ml, or the frozen mysis, the daily feeding amount is 10% of the hippocampus body ...

Abstract

The invention discloses a hippocampus erectus parent fish pairing method. The technical scheme of the invention is carried out under the condition of providing an aquaculture system and an aquaculture environment. The hippocampus erectus parent fish pairing method is characterized in that female sea horses and male sea horses are separately cultured for a period of time and then paired to ensure that the synchronization of incubation, the pairing rate of the sea horses is increased by mixing parent sea horses with different lengths under the condition of low density; before the parent sea horses are paired, the female sea horses and the male sea horses are separately cultured for at least 15 days until the gonads of the female sea horses are matured, and the density is 0.3-0.4/L; and after the gonads of the female sea horses are matured, and the matured female sea horses are paired with the male sea horses with the lengths of more than those of the female sea horses by 1cm, at most three pairs of sea horses are put in each vat according to the size of the culturing vat, and the specifications of the three pairs of the sea horses should contain large, medium and small specifications.

Description

technical field [0001] The present invention relates to pro-hippocampus pairing technology. 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, there is a common problem ...
