Abstract
The invention discloses a sterilization treatment method of live and fresh fish and shrimp bait for a giant salamander. The sterilization treatment method comprises the following steps: cleaning the live and fresh fish and shrimp with clean water, culturing the live and fresh fish and shrimp in clean water of a bait temporary culturing pond, wherein the water depth is maintained to be more than 50cm; 2, introducing ozone into the water of the pond to lead the content of the zone in the water of the pond to be up to 2-3mg/L gradually, maintaining the content for 5-15 minutes, then stopping the introduction of the ozone, and standing for 30 minutes; and 3, starting an aerator or adopting a water flowing mode to lead the content of oxygen in the water of the pond to reach the normal culture level of the fish and the shrimp. The step 2 is carried out for one time in the morning, at the noon and in the evening respectively, the step 2 is continuously carried out for two days, then the sterilization effect can be achieved, and the sterilized bait can be used for feeding the giant salamander. In the sterilization treatment method, the simpleness is achieved, the operation is easy, the efficiency is high, the sterilization is thorough, and the safety, non-toxicity and environmental friendliness are achieved. The live and fresh fish and shrimp treated by the method is the favorite for the giant salamander, and if the live and fresh fish and shrimp bait is eaten by the giant salamander for long time, the disease rate of the giant salamander is reduced, the increase of the body weight is faster, and the health index is higher.
Description
Technical field
The present invention relates to a kind of sterilization processing method, be specifically related to a kind of sterilization processing method giant salamander fresh aquatic food bait.
Background technology
Giant salamander; the popular name giant salamander; amphibian animal; belonging to national two classes in China watches for animals; have high scientific research, nutrition, medicinal, humanity and ornamental value; the giant salamander culture that rises in mountain area, the Chinese Qinling Mountains has tremendous development in recent years, and a whole nation year breeding amount has reached 1,000,000 tails, and a whole nation year number of animals raised has broken through 3,000,000 tails.The bait that giant salamander culture is used mainly is the fresh aquatic food fish and shrimp, but the fresh aquatic food fishes and shrimps often have multiple germ, causes easily the giant salamander disease if directly throw something and feed, in the actual production because of the unhealthy fresh aquatic food fishes and shrimps of throwing something and feeding cause giant salamander ill be the main cause of its morbidity.For a long time, people to handle the method for giant salamander bait be that common disinfectants has chlorine dioxide, PVP-I, potassium permanganate, quaternary ammonium salt etc. with the live fish and shrimp of buying back or fishing for disinfectant immersion treatment.Practice finds that there is various disadvantages in this immersion treatment method: 1. disinfectant is residual serious, does not reach the requirement of giant salamander green cultivation; 2. sterilization is not thorough, generally can only kill fishes and shrimps surface pathogen, and can not kill the pathogen that has infectd in the fishes and shrimps body substantially; 3. use disinfectant for a long time, pathogen produces drug resistance, only continues to increase the using dosage ability kill pathogens of medicine; 4. disinfectant is too big to the stimulation of fishes and shrimps, in spite of wound fishes and shrimps even can cause death, can strengthen aquaculture cost like this; 5. cause environmental pollution easily; 6. operation sequence is many, takes a lot of work, time-consuming, and overall cost is higher.For this reason, people explore a kind of better method of invention of considering always and handle the fresh aquatic food fishes and shrimps bait of feeding giant salamander, yet up to now, still do not have any mature technique and occur.
Summary of the invention
The objective of the invention is to propose a kind of new method of giant salamander fresh aquatic food fishes and shrimps bait sterilization processing.
This method is:
1. the fresh aquatic food fishes and shrimps are rinsed well with water purification, put in a suitable place to breed in clean bait storage pond, holding pond water, keep more than the depth of water 50cm;
2. charge into ozone to Chi Shuizhong, make the content of pond ozone in water reach 2-3mg/L gradually, and kept this content 5-15 minute, stop ozone then and charge into, the static maintenance 30 minutes;
3. open aerator or make the pond water oxygen level reach the breed level of normal fishes and shrimps by pipeline mode;
2 every days of above-mentioned steps are early, middle and late respectively carries out once, can reach thorough bactericidal effect in continuous two days.
Keep ozone to enter in the venting process and be preferred version from the bottom of storage pond, holding pond.
Bait by sterilization processing more than three days is best.
The inventive method is simple, easy operating, and the efficient height, sterilization is thorough, and the germ killing rate reaches more than 99.9%; Safety, nontoxic, environmental protection; The stress reaction that fishes and shrimps are produced because of anoxic, injured etc. when being fished for can very fast elimination, and can recover normal physiological status at short notice, and wound healing is fast, and it is very low to support in the phase death rate temporarily.Facts have proved that the fresh aquatic food fishes and shrimps of handling by the method are that giant salamander is favourite, eat it for a long time, the sick rate of giant salamander is low, and body weight increases very fast, and health index is higher.The fresh aquatic food fishes and shrimps bait of handling through the inventive method should be the optimal selection of giant salamander green cultivation.
Although the ozonization sterilization is a kind of on record prior art, and people want to abandon conventional method and unremitting are seeking the sterilization processing that better method in addition is used to feed the fresh aquatic food fishes and shrimps bait of giant salamander, but there be not the people that this technology of ozone sterilization is used wherein, disclosed yet without any technology related to the present invention.Therefore say that the present invention is the new method of the usual thinking of a kind of people of breakthrough, and its effect is remarkable.
The specific embodiment
The invention will be further described below in conjunction with embodiment.
Embodiment
1. the fresh aquatic food fishes and shrimps of just fishing for or buying are rinsed well with water purification earlier, put it into a 4m then
3In the clean bait storage pond, holding pond water, keep more than the depth of water 50cm.
2. the ozone generator with a 20W filled ozone 30-60 minute to Chi Shuizhong, made the content of pond ozone in water reach 2mg/L gradually, kept this content 5-10 minute, stopped ozone then and charged into, the static maintenance 30 minutes.Keep ozone to enter in the venting process from the bottom of storage pond, holding pond.
3. opening the aerator be installed on the storage pond, holding pond gives pond water oxygenation or opens water intaking valve and make the pond water oxygen level reach the breed level of normal fishes and shrimps by pipeline mode.
2 every days of above-mentioned steps are early, middle and late respectively carries out once, gets final product in continuous two days.Better by bait hello the giant salamander that the present technique processing time reached more than 3 days.
