I just read a news story about a man who noticed one of his prized Japanese carp was having some sort of an attack. When the fish rolled upside-down and became still, the man gave it a heart massage and mouth-to-mouth resuscitation. The fish revived and seems OK.
My question is - can a FISH be revived this way? Doesn’t the whole gills and breathing water thing get in the way of an air-breather’s rescue efforts?
