Recently, due to the large temperature difference before and after the white dew, continuous rainy weather, the breeding water environment and the breeding fish disease probability increased,

Time: 18 September 2023

Location: Renshou County, Meishan City, Sichuan Province

Water quality: nitrite: 0 .. 2 ammonia nitrogen: 0 .. 8 PH:6.5

Pond area and stocking specifications: 30 mu; 4-50000kg fish, about 2kg specifications

Analysis of the cause and etiology of stress hemorrhagic disease in the spotted fork tail?

The temperature changes greatly before and after the white dew, the weather changes suddenly, and there are many rainy days, resulting in low dissolved oxygen in the water.

The pond water environment changes too much, the stress is too large

Feed feeding rate is too high, feed quality is poor, resulting in the lack of nutrients such as vitamins in cultured fish, long-term feeding is easy to cause hemorrhagic disease

Etiological analysis: in most cases, there is no obvious abnormality in the fish body, but if the fish body is stimulated by stress factors (netting, fishing, transportation), it will be extremely sensitive, and the fish body surface fins, caudal fins and other places will be significantly congested and red in a short period of time, and even accompanied by enteritis in severe cases. The following figure:

Treatment plan

External use: use super strong solution to optimize the water environment, the amount of 10 mu * m/barrel

Internal administration: stop the feed for one day, maintain an appropriate feeding rate every other day, mix the feed with enrofloxacin (2000kg fish/bag), neomycin sulfate (2000kg fish/bag) + nano Jinwei (1 bottle mixed with a bag of feed), take the feed twice in the morning and evening, and mix the feed for 5 days continuously. Two courses continued.
