The Nile Tilapia found in the Yarkon River is a species with a notable presence and historical significance. The name "tilapia" is derived from the Tswana word 'tlhapi,' meaning "fish," and the genus was named by Scottish zoologist Andrew Smith in 1840. These fish are characterized by their laterally compressed, deep bodies and an efficient feeding system that includes a second set of jaws for processing food.

In the Yarkon River, the Nile Tilapia is one of several species that have adapted to the changing environment. While the Yarkon River has faced pollution and ecological challenges, especially after the 1950s, efforts have been made to rehabilitate it, and the presence of these fish indicates a degree of ecological recovery. The Nile Tilapia in the Yarkon are part of the river's complex ecosystem, which includes a variety of fish and other wildlife.

The area around the Abu Rabbah Mill on the Yarkon River is particularly notable for outdoor activities. During the winter, the region's rough terrain can be navigated using high-clearance vehicles like jeeps, making it an ideal spot for adventurous off-road exploration. The presence of tilapia and other species adds to the ecological richness of the area, making it a fascinating destination for nature enthusiasts and recreational visitors alike.
