Embodiment Construction

[0007] The newly produced seedlings have a body length of only 0.8 to 1 cm, can be fed on the same day, and are immediately put into the nursery pond for cultivation. Fry cultivation generally refers to the process of cultivating from primary seedlings to 6 cm long fry. Fry breeding is an important stage of artificial seahorse breeding, and it is necessary to prevent the fry from being infected with diseases and dying in large numbers. Mainly need to master the following points:

[0008] 1. The cultivation water should be clean, fresh and pollution-free, and the pool water should be cleaned and replaced every other day. If it can be cultivated in running water, the survival rate will be higher.

[0009] 2. The water temperature requires a stable temperature. The temperature should be controlled at 20-28°C, not lower than 18°C, and not higher than 30°C. The sudden change in temperature difference does not exceed 2°C.

[0010] 3. Fish fry with strong physique can eat soon af...

Abstract

The invention relates to a method for artificially breeding a sea horse seeding. The method is to adopt the siphonage to discharge half to two thirds of stale sea water in pool within two or three days after hatching of sea horse, absorb completely sewage on the pool bottom, and add fresh sea water. When water is refreshed, the temperature difference between the stale sea water and refresh sea water is not more than 3 DEG C. The length of the bred seeding body is only between 0.8 and 1 centimeter, and the bred seeding stocking is between 150 and 200 tails per cubic meter. The bred seeding is fed for three times a day, the bait amount cast each time is about 10 to 20 percent of the weight of the sea horse, and the adjustment of water temperature and light, as well as the prevention and treatment of damage work are carried out properly. The method can realize the scale artificial breeding of the sea horse seeding, and has the advantages of low breeding cost, high seeding survival rate and so on.

Description

technical field [0001] The invention relates to a method for artificially cultivating hippocampus seedlings. technical background [0002] Hippocampus, known as "Southern Ginseng", has always been listed as a valuable and high-grade Chinese herbal medicine, and is loved by people and favored by domestic and foreign markets. Currently, about 20 million seahorses are traded in the world every year. However, due to the increasing demand and overfishing, natural seahorses are depleted and the price is skyrocketing. Seahorse seedlings have high requirements on the temperature and salinity of the cultured water, and their seedling cultivation is difficult. Contents of the invention [0003] The object of the present invention is to provide a method for large-scale artificial cultivation of hippocampus seedlings. [0004] The above-mentioned purpose of the present invention is achieved like this: [0005] A method for artificially cultivating seahorse seedlings. The specific s...
