Pond Boss Forums STOCKING A NEW POND Types of fish to choose Some dead fish please help-pics included

I have been getting some fish from my local fish farm. They all looked healthy when I got them. I have to transport them in a huge cooler with a small aerator about 15min from his place to mine. Recently I put in 6 grass carp. Two of them died and this is what they looked like. Any idea what is on their body? I also recently put in 20 trout, one died so far. It didnt look like these but didnt look healthy either. The fish farm is licensed by NYS health dept. My pond is 3/4 acre. 20-25 ft deep in the deep end about 1/2 acre worth then it shallows out. It is really, really cold towards the bottom. I have a ton of healthy minnows, frogs, crayfish and LMB. What do you think?

The pic is one of the carp I found half floating. I took it out of the pond to photo it and make sure if it had something nothing else got it. This was 3 weeks ago.

I bought 12 grass carp from Smith Creek Fish Farm in Bliss NY a couple of years ago.

I put the fish in my ponds as per usual acclimation procedures, and found 3 of them dead the next day.

I never really got an explanation from the fish farm other than "that normally doesn't happen"

A fourth one died the next year, but I don't know how. By the time I found it, it was up on the shore half eaten by a raccoon or something.

A 15 min. trip in a cooler with an aerator should be no trouble at all for the fish.

Sorry to pass on a non-answer, but just wanted you to know the same thing happened to me, with no real explanation.

They really look in rough shape in those pictures, quite the "rash" they have...

Those fish appear to have bacterial-fungal growths. This is a pretty typical occurrance for fish that have gone though stressors of seining, holding, traveling, netting, holding, netting more times, holding again and then final netting sale and transport. It is a wonder as many fish live as they do considering how they are handled and or mishandled. Good reputable fish farms should replace fish that die if you document the occurance with pics and numbers. IMO many small stocked fish are eaten by predators and scavengers before they are completely die, sink or surface.
