Abstract
The present study reports the fish fauna of Gomal Zam Dam at three different sites from October 2018 to July 2019. The total sampled fish belong to 18 species, 15 genera, 5 families, and 4 orders. Fourteen species belong to family Cyprinidae, which was the most abundant, while one species belong to each family Mastacembelidae, Channidae, Siluridae, and Sisoridae. The prominent species were Labeo dyochielus (18.6%), Barilius vagra (16.5%), and Barilius pakistanicus (13.8%), while the rare species were Tor zhobensis, Wallago attu, Hyphophthalmicthys molitrix, Ctenophyrngodon idella, and Bagarius bagarius each one forming (0.1%). Species were rich in spring with ideal temperature, followed by summer, whereas species abundance was high in summer with high temperature and minimum abundance was recorded in autumn. In conclusion, the Gomal Zam Dam is a favorable reservoir for the fish particularly for family Cyprinidae. This present study will provide useful information about the diversity of fish fauna of Gomal Zam Dam that could be used in systematic fisheries management and conservation of the country.
