In 5 months 2019, the grass carps in the farm showed signs of being infected with the ichthyophthirius multifiliis, and the following three experiments were performed.
1. Evaluation of ozone insecticidal effect: collecting adult ichthyophthirius multifiliis on the surface and gill of the diseased fish, and putting part of the adult ichthyophthirius multifiliis in clear water to form cysts and larvae. Placing 30 adults and cysts on a screen, placing the adults and the cysts at the middle position of an ozone action area, an ozone consumption area and the tail end position of the ozone consumption area, wherein the corresponding ozone concentrations are 0.1mg/L, 0.06mg/L and 0.02mg/L respectively, and recording the death time of the adults. 1ml of larva water sample is added into 9ml of ozone water in three areas, and the death time of the larva body is observed under a microscope. The observation time was 1h, and 3 replicates were performed.
TABLE 1
The insecticidal effect of ozone is shown in table 1, the ozone concentration of 0.1mg/L can effectively kill the larvae of the ichthyophthirius multifiliis in a short time, 0.06mg/L needs a longer time, and the lower ozone concentration has no insecticidal effect. Ozone concentrations of 0.1mg/L and below were not lethal to both adults and cysts.
2. Evaluation of lethality of ozone to grass carp: 30 healthy grass carps (with the weight of 2080.6 +/-159.4 g and the body length of 52.3 +/-5.5 cm) are respectively placed at the tail end of the ozone action area, the ozone consumption area and the culture pond, the ozone concentration of 3 areas is 0.1mg/L, 0.02mg/L and 0mg/L respectively, and the survival rate after 48 hours is counted.
TABLE 2
| Region(s) | Survival rate |
| Zone of action of ozone | 73.3％ |
| Ozone depletion region end | 100％ |
| Culture pond | 100％ |
As shown in Table 2, the grass carp dies only at the ozone concentration of 0.1mg/L, the gill tissue of the dead grass carp is congested and swollen, the breathing frequency of the grass carp is accelerated during the experiment, and the reaction is slow, which indicates that the ozone concentration can cause great damage to the gill tissue of the grass carp. The other two groups of grass carps have no adverse effect and no death.
3. The evaluation of the effect of the method for treating ichthyophthiriasis of grass carps comprises the following steps: grass carp infected with the ichthyophthirius multifiliis (body weight 2080.6 + -159.4 g, body length 52.3 + -5.5 cm) were tested with 100 tails per group. Performing experiments on a control group and a running water treatment group in an unmodified fish pond, wherein an axial flow pump is additionally arranged at a water inlet of the running water treatment group; the ozone treatment group and the running water + ozone treatment group were performed in a modified fish pond. The water pump is started for 7h every day along with the ozone device, the first week of the ozone device is started according to the water temperature of 20 ℃, the time (19-23h) required by cyst development into larva and the flow rate (2 m) of the pool3Min) and total water amount (756 m)3) And calculating, starting the system for 7 hours every day to circularly kill the insects of the culture water body once, and adding and subtracting according to actual conditions after one week. The feed feeding conditions of the control group and the treatment group are consistent, the experiment is carried out for one month, and the survival rate is counted.
TABLE 3
| Mode of treatment | Survival rate |
| Control group | 19％ |
| Running water treatment | 71％ |
| Ozone therapy | 55％ |
| Running water plus ozone therapy | 82％ |
As can be seen from Table 3, the survival rate of the grass carp in one month in the three treatment groups is obviously higher than that in the control group, the survival rate of the running water treatment group is slightly higher than that in the ozone treatment group, and the survival rate is highest under the combination of the two treatment methods, so that the propagation of the ichthyophthirius multifiliis effectively inhibited under the action of the water flow and the ozone, and the loss is greatly reduced.
The above is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any equivalent changes, equivalent substitutions or modifications made based on the present invention to solve the same technical problems and achieve the same technical effects are also within the scope of the present invention.
