Ringworm is a parasite, in the water temperature is relatively easy to reproduce, if the number of grass carp in the breeding pond at this time is large, more dense, it may lead to a large number of fish ringworm, the harm is relatively large. Ringworms will parasitize on the surface of the fish body, the symptom is that the mucus on the surface of the body increases, and there may be congestion or bleeding; if the ringworm parasitizes on the gills of the fish, then the symptoms may also be the gill cover of the fish open or the gill filament swelling.

1． prophylaxis
Dry clear ponds, with 100 kg of quicklime per acre. Fingerlings can be soaked with 20 mg/elevated potassium manganate solution for 15 to 30 minutes before stocking to kill parasitic ringworms on fingerlings. Before stocking, summer flower fingerlings should be soaked with 1 gram of crystalline insects per cubic meter of water for 20 to 30 minutes to better prevent ringworm disease.
<h1 class="pgc-h-arrow-right" data-track="21" > after the seedlings are released and fed with [Ao worm net] mixture for 5-7 days can effectively inhibit the ring worms in the body. </h1>
2． treat
With Auex Fishing Australis + Australoside, mix the feed continuous feeding for 5-7 days.
Each mu of water depth of 1 meter is sprinkled with a whole pond of fungi, and then sprinkled again after 2 days, which can treat ringworm disease in farmed fish.
