Riyadh, June (پاکستان پوائنٹ نیوز 23 يونيو 2026ء) The migration was observed during routine freshwater field surveys conducted after the end of the rainy season and the onset of the dry season. Visual observations and photographic records documented massive schools of fish moving collectively and in a synchronized manner toward the upper reaches of the wadi. The fish were observed climbing wet rock faces adjacent to waterfalls, outside the main watercourse and within the spray zone, demonstrating a remarkable ability to avoid being swept away by strong currents.
The Aseer Garra fish is a bottom-dwelling freshwater species endemic to the Kingdom. It is found in wadi systems originating in the Aseer Highlands, including the basins of Wadi Turabah, Wadi Ranyah, and Wadi Bisha, covering an estimated area of 500 square kilometers. The species plays an important ecological role in regulating algal growth in wadis and rock pools by feeding on algae and organic matter attached to rocks.
The significance of this documentation lies in its contribution to understanding the ecology and behavior of this endemic species. It provides new insights into its movement patterns within mountain wadis and highlights the relationship between its distribution range and its ecological role within freshwater ecosystems.
