After feeding, grass carp gather in groups and lie at the water surface, similar to oxygen deficiency - what is going on?
After grass carp finish feeding, they gather in groups and lie at the water surface, with symptoms similar to oxygen deficiency
The attached image is as follows.
Generally, such symptoms are caused by overfeeding or water that is too fertile, but after adjusting the water and reducing feeding, the situation remains the same.

In our grass carp ponds here, after feeding ends, many also come up on the downwind side to eat floating feed.
--------------------------------------
These are symptoms of metabolic disorder syndrome, mainly a problem with oxygen metabolism, like lung disease in humans, because after fish feed they need a large amount of oxygen to help digest the feed. At this time, the oxygen demand is much higher than when not feeding, and the body's oxygen supply is insufficient, so this symptom appears. Therefore, before treatment, it is necessary to determine whether this disease is a problem with the gills or a problem with the body's internal oxygen transport system

Need to wash up, arm yourself with knowledge
--------------------------------------
We often encounter this problem here too, and it cannot be solved! Many farmers now have gotten used to it.

Why do fish with metabolic disorder syndrome lie at the water surface?
--------------------------------------
The cause of this symptom cannot be explained clearly
It is everywhere
--------------------------------------
Good material, definitely definitely definitely definitely definitely definitely!
--------------------------------------
I am certain the livers of the fish here definitely have problems.
--------------------------------------
Not sure, but nowadays many people looking at fish diseases, when they encounter uncertainty, fool farmers by saying it is hepatobiliary syndrome

May I ask the original poster, do your grass carp only show this phenomenon after eating feed? Does this phenomenon occur regardless of how much feed they eat? Do the fish sink down and then float up again with their heads tilted high?
