Embodiment 1

[0022] 1. Breeding system

[0023] The area of ​​the Penaeus vannamei breeding pond is 3 mu, the average water depth is 2.2 meters, and the deepest is 3.0 meters; the pond is equipped with bamboo with branches and mesh for seahorses to climb. The pond is equipped with a 2.2KW blower, and a nano-inflatable pipe ring with a diameter of 20 cm is installed every 30 square meters.

[0024] 2. Breeding environment

[0025] During the breeding period, the minimum water temperature is 19-20°C, the maximum water temperature is 32-33°C, the daily temperature difference is 2-2.5°C, the salinity of the breeding water is 33-36‰, and when the salinity is higher than 36‰, add fresh water and drop it to 33‰ ‰the following. After the pond is filled with water, kill fish with deer vine essence clear pond, fertilize the water to promote algae reproduction, make the water transparency reach 60-70 cm, add EM bacteria (Xiehe brand), naturally cultivate copepods, and the density of copepods reache...

Abstract

The invention relates to a large-scale culture method for hippocampus erectus in a pond. By means of the method, pond copepods and opossum shrimps are used as hippocampus baits at the same time, and the pond copepods and opossum shrimps are combined, so that the hippocampus culture bait cost can be reduced by 80%, the labor cost can be reduced by 50%, large-scale capital construction is not needed, and the hippocampus erectus culture benefit is greatly improved.

Description

technical field [0001] The invention belongs to the field of seahorse cultivation, in particular to a method for cultivating large-scale gray seahorses in ponds. Background technique [0002] Hippocampus is a traditional Chinese medicine. According to statistics, more than 300 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 7,000 yuan per kilogram. Calculated based on the annual import of 300 tons, the value exceeds 2.1 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. In the past five years, the seahorse breeding technology in my country with the gray seahorse (Hippocampus sectus) as the leading species has developed rapidly, ...
