|Dan, I wonder if you are not confusing carp with yellowfish iro the articles in TCFF magazine. The first mentioned is an invasive exotic with the latter comprising nine indigenous species in South Africa, fight much harder and are typically referred to as “freshwater bonefish” over here. One of the nine species is called the largemouth yellowfish and is a predator of note – you just have to look at its mouth to see why. Yellowfish are highly regarded and treasured in South Africa and one of the all-time must fish for freshwater species to catch in the world.|
I’ve include a pic of a largemouth yellowfish (top), smallmouth yellowfish (middle) and a pic (from Wikipedia) of the common carp (bottom). There are a number of key distinguishing features, but a useful one is the dorsal fin of carp which extends to almost the tailfin – on yellowfish the dorsal fin is much shorter and typically more “bonefish like” in nature.
