| The significant status of fish in one’s life and in animal kingdom needs no debate all around the globe due to their niche ecology and stress of environment. Such a vast and un-exposed habitat structure has varied impact on biotic regime to support abiotic resources in this ecotonic belt of foot Himalaya including crisscross rivers valley, streams and khads. The pristine streams of rivers in Solan District harbor fishes of commercial importance on and near Sirsa riverine system in Baddi area. The fish diversity in this foot hill ecotone range includes 35 species (4 Orders, 6 Families and 25 genera) out of which Cypriniformes act as dominant order (29 sp < em>.) with 2 species of each of the following orders Siluriformes, Perciformes and Synbranchiformes, as per earlier study. The upper reaches of Sirsa and its riverine tributaries were rich in some species of genus: Danio, Chagunius, Barilius, Garra, Glyptothorax, Puntius, Tor, Mastacembalus, Crossocheilus, Devario, Acanthocobitis, Schistura, Macrognathus, Badis and Schizothorax or Oreinus. The important fishes in order of their abundance include Channa gachua, Cyprinus carpio var. specularis, Labeo rohita, Labeo calbasu, Cirrhinus mrigala and Aorichthys seenghala (Fig. 1). As per IUCN Red List, the above reported 21 fish species in present studies, 16 species are categorized under the Least Concern (LC), 2 species are designated as Vulnerable (VU), 1 species falls into the Data Deficient Category (DD), 1 species has not been evaluated (NE) and 1 species is classified as Endangered (EN). The facts, such as scientific outcome and perceptions, reduced fish numbers, new trends and environmental stress ecology, research input gap at grass root level to narrow issues and combat steps for further conservation and water management, have been kept in light. | ||||
