Lots of these tiny fish swimming in the shallows. No idea how they got into the pan. The numbers increase every time we see them.
This big dying carp was drifting just under the surface and when I tried to take it out it wriggled out of my hands into the wetland vegetation. When I recaptured it I placed it on the vegetation for the photo.
I removed it from the water to prevent contamination and let the water mongoose have a free meal. When I put it down in the grassland, there were numerous lice squirming out of the scales. I collected some which was probably 20-30 in my jar but there would have been more on the fish. This could have been the cause of death because I took a water sample and ammonia was almost zero.
EDIT: The cause of death was probably botulism type C as this year it affected birds and we found a fish with the same symptoms. Type C can affect carp.
