Method for culturing flame turtles
A breeding method and technology for flame turtles, which are applied in chemical instruments and methods, fish farming, pharmaceutical formulations, etc., can solve problems such as the need for hibernation of flame turtles, increase the cost of flame turtle breeding, and low breeding density, and reduce biological oxygen consumption. Quantity, avoid water quality deterioration, improve the effect of breeding density

experiment example 1
[0031] Experimental example 1 The effect of ozone on the survival of loach and flame turtle
[0032] Introduce ozone into the breeding pond so that the ozone concentration in the water body is 0, 0.002, 0.004, 0.006, 0.008, 0.01, 0.012 mg / L, respectively. 50 loach seedlings and 30 flame turtle seedlings are put into the breeding pond. The survival rates of loach and flame turtles at 4h, 8h, and 12h were counted. The results are shown in the following table:
[0033] Survival rate statistics table
[0034]
[0035] The results in the table show that when the ozone concentration is lower than 0.06mg / L, the survival rate of flame turtles in ozone water for 6 hours is 100%, while the survival rate of loach in ozone water is still 99.3%. When the ozone concentration is lower than 0.06mg / L Within 6 hours, the behavior of the flame turtle is normal breathing, movement is normal, and there is no agitation, indicating that for a short time, low concentration of ozone has no effect on the fla...
experiment example 2
[0036] Experimental example 2 Purification effect of ozone on water quality
[0037] Take 1L of the breeding water in the flame turtle breeding pond and pass in ozone to make the ozone concentration in the water body 0, 0.002, 0.004, 0.006, 0.008, 0.01, 0.012 mg / L, 20 minutes later, detect the nitrite content in the water body , Ammonia nitrogen content and hydrogen sulfide, the results are shown in the following table:
[0038] Ozone water concentration (mg / L)
[0039] From the results in the table, it can be seen that after ozone is introduced into the aquaculture water, the nitrite content, ammonia nitrogen content and hydrogen sulfide content in the water all decrease to varying degrees. The ozone water concentration is 0.002mg / L. Nitrate content has dropped by about 25%, ammonia nitrogen content has dropped by 9%, hydrogen sulfide content has dropped by 36%, and it can be seen that even at low concentrations, ozone can still effectively oxidize nitrite, ammonia nitrogen and...
Embodiment 1
[0041] A method for breeding flame turtles, which includes the following steps:
[0042] 1) The construction of aquaculture pond: a protective fence 1 is installed on the periphery of the aquaculture pond, wherein the aquaculture pond includes:
[0043] The pool area 5 has an inverted trapezoid structure in cross section. The pool area is provided with a perch platform 2, a water inlet, and a drain; the perch platform 2 is provided with 2 layers, and the interval between each layer is 60 cm. The perch platform The width of 2 is 40 cm, the bottom of the pool area 5 is covered with sand, and an aeration pipe 3 is laid on the surface of the sand.
[0044] The basking area 4 is arranged on the side of the pool area 5 and connected to the pool area 5, and the level of the basking area 4 is lower than the protection fence 1. as well as
[0045] The environmental control system includes a central controller, a dissolved oxygen detector, an aeration pump, and a water temperature detector, th...
