Fishing in the Eastern Cape Province is as diverse as the fauna and flora it boasts. Stretching from the Indian Ocean to the mountain kingdom of Lesotho. The Eastern Cape is truly a province of extremes. Wild waves churned by gale force winds in the south of the province, to snow, rugged mountain peaks and crystal clear mountain streams and lakes in the north. Though Yellowfish are mostly found in warmer water tributaries, they do live and thrive in cold water rivers and streams as well. The Orange and Kraai rivers hold indigenous Yellowfish species which include the Largemouth Yellowfish (Labeobarbus kimberleyensis) and Smallmouth Yellowfish (Labeobarbus aeneus) which are more common to this region. The Gariep dam also borders the province and offer many opportunities to target Yellowfish. Smallmouth Yellowfish have been introduced to the Great Kei and Great Fish rivers and are seen as alien species that can become problematic to the biodiversity in these water ways. The Orange River has its origin in the Lesotho Highlands where it is called the Senqu River. Traditionally this river runs quite clear except for the occasional flush floods that can stain the water.
