The largemouth yellowfish or Vaal-Orange largemouth yellowfish (Labeobarbus kimberleyensis) is a ray-finned fish species in the family Cyprinidae.
The Largemouth Yellowfish is the largest scale baring fish in South Africa, and of course is the largest of all Yellowfish species.
Are known affectionately as Largies, and are one of the hardest and most frustrating freshwater fish species to target on a fly fishing rod and reel, or any tackle actually, which makes them such a big prize in many anglers eyes.
This species of the Largemouth yellowfish is vulnerable, and is becoming increasingly scarce due to illegal netting, long lining, water abstraction and water pollution.
The largemouth yellowfish occurs in the Orange and Vaal Rivers and their larger tributaries in Lesotho, Namibia and South Africa. In the latter country, it is found in Eastern Cape Province, Free State, Gauteng, Mpumalanga, North-West Province and Northern Cape Province.
Is predominantly found in deep pools of large rivers, as well as in the slow-moving water before weirs and river dams. Abundant water weeds, overhanging riparian vegetation and other forms of plant cover seem to be essential for its well-being.
Overhanging trees and cliffs also offer something to the Largemouth Yellowfish and they can be found here as well.
The Largemouth Yellowfish will feed on a variety of insects, insect larvae, plankton, algae and other organisms until it reaches a weigh of about 1.5 kilograms. They then become almost exclusively piscivorous, but will still take crustaceans and crabs and so forth.
Horizon TRS 9 wt for most of the largemouth yellowfish fishing (yes you are fishing a big river with biggish, heavy flies); and the new 10 ft Horizon Tactical Competition 6 wt for targeting smallmouth yellowfish and other smaller species in the shallow runs.
The Rio InTouch Coldwater Striper floating line worked fine for swinging the bigger, heavy flies and I fished it most of the time; as recommended by Garth Wellman I also fished an Airflo Forty Plus type 5 sinking line to load the rod quickly and to get down in faster, deeper water (where he typically caned fish); and various floating, intermediate and sinking backups for my 6 wt outfit.
