Embodiment 1

[0025] Killifish breeding water configuration, the mass fraction is 1 part of terminal seed leaves soaked in 500 mass parts of tap water after 2 days of aeration for 15 hours, to obtain the terminal seed leaf soaking water, and then soak the terminal seed leaves Water conditioning Tap water aerated for 2 days to bring the water to a pH of 7.0. If the pH of the water is too high or too low, it is not conducive to the hatching and growth of killifish. Tap water contains toxic substances such as chlorine gas. Aeration can reduce the toxicity of water. It is more suitable to adjust the pH of killifish breeding water by soaking terminalia leaves in water. The living environment of killifish.

[0026] It takes a long time for fish eggs to hatch due to the unique reproductive habits of killifish. The egg changes generally as follows: transparent-light yellow-dark yellow-blacken-dark eye circles-golden eye circles. First add the killifish breeding water of 0.5L in the container, put ...

Embodiment 2

[0034] Killifish breeding water configuration, the mass fraction is 1 part of terminal seed leaves soaked in 650 mass parts of tap water after 5 days of aeration for 12h, to obtain terminal seed leaf soaking water, and then soaked with terminal seed leaves Water Conditioning Tap water aerated for 5 days to bring the water to a pH of 6.5. If the pH of the water is too high or too low, it is not conducive to the hatching and growth of killifish. Tap water contains toxic substances such as chlorine gas. Aeration can reduce the toxicity of water. It is more suitable to adjust the pH of killifish breeding water by soaking terminalia leaves in water. The living environment of killifish.

[0035]It takes a long time for fish eggs to hatch due to the unique reproductive habits of killifish. The egg changes generally as follows: transparent-light yellow-dark yellow-blacken-dark eye circles-golden eye circles. First add the killifish breeding water of 1.0L in the container, put 100 fis...

Embodiment 3

[0043] The configuration of killifish breeding water is that the mass fraction of 1 part of terminal seed leaves is soaked in 800 parts of tap water aerated for 24 hours for 24 hours to obtain the soaking water of terminal seed leaves, and then use terminal seed leaves Soak water Conditioned tap water that had been aerated for 3 days to bring the water to a pH of 8.0. If the pH of the water is too high or too low, it is not conducive to the hatching and growth of killifish. Tap water contains toxic substances such as chlorine gas. Aeration can reduce the toxicity of water. It is more suitable to adjust the pH of killifish breeding water by soaking terminalia leaves in water. The living environment of killifish.

[0044] It takes a long time for fish eggs to hatch due to the unique reproductive habits of killifish. The egg changes generally as follows: transparent-light yellow-dark yellow-blacken-dark eye circles-golden eye circles. First add the killifish culture water of 2.0...

Abstract

The invention relates to a killifish culture method. The method includes the following steps: culture water, the pH of which is 6.5 to 8.0 and the oxygen content of which is 4mg / L to 8mg / L, is adopted to incubate spawns under 24 DEG C to 30 DEG C for 4 to 12 hours, incubated larvae are fed with brine shrimp larvae after 10 to 15 hours, water is changed every three days, and the amount of changed water is 1 / 10 to 1 / 5 each time; after 10 to 20 days, the larvae are grown into adult fishes, the adult fishes are transferred into a culture tank for raising and fed with fairy shrimps, water is changed every two days, and the amount of changed water is 1 / 8 to 1 / 4 each time. The culture method for culturing killifishes is easy to operate, and moreover, both the incubation rate and the survival rate of the killifishes are high.

Description

technical field [0001] The invention relates to a method for cultivating fish, in particular to a method for cultivating killifish. Background technique [0002] The killifish not only has a small and exquisite body and bright colors, but also is favored by countless killifish fans because of its unique breeding method. Killifish roe can be mailed across continents while being dried and preserved, and bloom in distant exotic places. Due to the harsh natural environment of the original place, killifish have a unique way of survival. Their fish eggs must go through a long period of dry storage (about 1 to 8 months), and repeat the process of soaking→drying→soaking several times before they can develop normally. [0003] At present, in the process of killing killifish, due to the lack of understanding of the original living environment of killifish and the unique breeding method of killifish, the survival rate of killifish is generally low. Contents of the invention [0004...
