How common is this parasitic infection that causes dropsy, and is it common practice that fishery management remove and treat infected carp ? What´s the survival rate, if left untreated ?
In reply to Post #1
Dropsy is a bacteria called Aeromonas which exists in most waters (often get in in fish tanks) it's only when the carp get stressed / old / or is not well, theirs too many fish in there / or water quality is poor this occurs.
So if one fish is infected it does not mean another one will catch it.
If a carp has dropsy it's probably too late and if untreated will likely die.
In fish keeping you'd likely isolate that fish and put it through a salt bath or use an antibacterial fish food, not practical for a fishery.
So in answer the only way to treat dropsy is to understand what is causing the problem hopefully it's just a one off and the carp was already in poor health due to other reasons.
