Abstract

The current study aimed to investigate the diversity and distribution of freshwater fish in the districts of Sawabi, located in the northwest of Khyber Pakhtunkhwa province, Pakistan. Sawabi is home to numerous streams and rivers between the Indus and Kabul rivers, making it an important area for fishing and farming. A total of 350 fish samples were collected from February to November 2021. Eight species were identified in Sawabi, including Oreochromis niloticus, Catla catla, Carassius gibelio, Tilapia sparmanii, Mystus seenghala, Cyprinus carpio, Rutilus rutilus, Tor tor, Hypopthalmichthys molitrix, and Dorosoma cepedianum. The results suggest that overfishing and water pollution are major factors affecting the survival and expansion of fish species in the area. To improve the fish populations in the rivers and streams, proper stocking and regulations to control overfishing and pollution are needed. The study found that the Cyprinidae family was the most dominant, with ten species identified in the experimental area. However, the number of Tilapia sparmanii and Hypopthalmichthys molitrix was found to be low due to pollution, toxic heavy metals, and other environmental factors that affect breeding and other activities of fish.
