When Koi is sick, we need to know the cause and treatment of Gill rot disease of Carp.

The main results are as follows: (1) the Gill filament is commonly known as "skylight". In severe cases, the cartilage at the end of the Gill filament is exposed, the medial epidermis of the operculum is congested, and the central epidermis is often corroded into a round and transparent hole.

(2) Gill mildew caused by fungi, the gills of diseased fish are pale, and sometimes there are spots of congestion or bleeding. The disease often causes sudden death of fish, and microscopic examination will find Gill mycelium.

There are three main causes of Gill rot in koi:

① bacteria, fish-infested myxococcus causing bacterial Gill rot

② fungi, Gill mildew caused by Gill mold

(1) the chlorinated hydantoin or dibromohydantoin 0.3 × 10 6 was sprinkled in the whole pool and used again every other day for severe cases. At the same time, it was mixed and fed with Yufening, allicin and fish blood in the proportion of 0.2%.

day.

(2) 0.25 × 10 ~ (- 6) superiodoquaternary amines were sprinkled in the whole pool.

(3) 1 × 10-6 bleach is sprinkled throughout the pool.

(4) soak with 0.5 grams of salt water and 20 × 10 6 erythrotoxin.

(5) 1 × 10 6 povidone iodine is sprinkled in the whole pool.

Due to the mass reproduction of parasitic protozoa, ① stimulates the gills of fish to produce a large amount of mucus, making it difficult for koi to breathe, so it floats for a long time, blackens its body color in severe cases, and swims alone.

Floating surface

The Gill disease caused by ④ Chinese flea is white at the end of the Gill filament, parasites many worms and hangs maggot-like worms, so it is called "Gill maggot disease".

(1) sprinkle with a powerful insecticidal or fungus killer with a concentration of 0.01 × 10 ~ 6 ~ 0.02 × 10 ~ 5.

(2) take Yujing Chongke internally and feed it twice. Every 50 grams of feed is dispensed with 200 grams.

(3) sprinkle with compound synergistic trichlorfon 150 grams per mu.
