What are the successful cases of treatment after the emergence of bacterial head explosion disease in Pelteobagrus fulvidraco?

Basic information Location: Ao Village, name of the farmer: Wang Fusheng, with 40 mu of aquaculture water, mainly breeding Pelteobagrus fulvidraco. Disease pool: the culture area 10 mu, the water depth 1.5, the culture species is Pelteobagrus fulvidraco, and the feed feeding amount is 120kg/ meal.

Symptoms? The indicators of fish: pH: 7.5, ammonia nitrogen: 0.2, nitrite: 0. 12, and a small amount of cyanobacteria floating on the surface of the pond. On the body surface, there were symptoms of mushroom head explosion, severe fin congestion, severe fatty liver, gastric ascites and intestinal congestion, and food could not be found, so eating was slow. Fish microscopic examination showed that there were no insects in teeth and mouth. The pond was ill for 2 weeks, and died every day at the peak 180 people.

Use plan on the afternoon of July 24th: Stress Jieduling+Jieshuiling (5 bottles plus 5 packs) (120 dead fish all day)

On the morning of July 25th, 5 mu of compound iodine +5 digitalis was used in each group (3 bottles+15 package).

On the afternoon of July 25, each bag of doxycycline hydrochloride+Corynebacterium+Stress Ning was mixed with 60 kg of substance, once a night for three consecutive meals.

It started to be used on July 27th, and the death toll decreased obviously, from 20kg to more than 10 five days later.

In the later prevention and control plan, it is suggested that the water body should be disinfected in about 15 days: 3 packages of compound iodine and Sanhuang powder (5 μm/ group).

Oral regimen: one bag of Banlansimin (500g) and one bag of Stress Ning (150g) were mixed with 60kg of materials, once every 5-7 days and fed twice a month. According to the preventive advice given by Huayang, by the beginning of September, there was no death in Boss Wang's pond.

Summary analysis 1. Through understanding and observation, the main causes of the disease are: high breeding density, excessive feeding, deterioration of water quality, excessive feed residue and corruption affecting water quality. Second, long-term non-disinfection, dead fish buried deep, leading to the spread of germs.

2. To control diseases, we must first create a good environment for raising animals, then treat both internal and external problems, disinfect the external environment, kill pathogenic bacteria and protozoa, and take orally to protect liver and gallbladder to promote drug absorption, enhance physical fitness and eliminate pathogenic bacteria in the body.

3. Doxycycline hydrochloride+ladybug+Stress Ning can kill both gram-positive bacteria and gram-positive bacteria. This scheme is better for the case of inaccurate judgment of pathogens.

4. If you raise fish, it is recommended to adopt Huayang health care model, which can prolong the breeding time, reduce the death, improve the utilization rate of feed, and the cost of health care drugs will not increase!
