Fishes are the very good indicator of the aquatic habitat and also are the chief protein source. Present study was conducted to document the icthyofaunal diversity of Tilaiya reservoir of Koderma district, Jharkhand during January 2018 to June 2018 and recorded 44 fish species belonging to the 05 orders and 16 families .Cyprinidae was the most diversified fish family .Among the 44 fish species 20 species are under the Cyprinidae family,03 species of each are under Channidae and Chichilidae,02 species of each fishes are under Belitoridae,Ambassidae, Notopteridae,Bagaridae and Mastacembelidae whereas 01 species of fishes are under Cobitidae ,Anabantidae Gobiidae, Belontiidae, Claridae, Heteropneustidae, Pangassidae and Siluridae.Further 37 fish species are under IUCN-LC category,05 species are under IUCN-NT category,01 species is in IUCN-DD category whereas 01 species is under IUCN-VU category
Present study was conducted to document the icthyofaunal diversity of Bokaro district Jharkhand during Monsoon season. Survey were made on River, Reservoir and major hill stream area of Bokaro district Jharkhand during June to September2017.A total 42 species of fishes belonging to the 6 order 16 families and 28 genera. Out of the total 42 species of fishes 18 species belonging, Cypriniformes,12 species is in Perciformes 08 species is in Siluriformes 02 species is in Synbrachiformes and one species of each Mugilliformes and Osteoglossiformes order .Further the fish species belonging to 15 species is in Cyprinidae family,04 species is in Channidae family,03 species of each Bagaridae and Cichilidae,02 species of each is in Mastacembelidae and Ambassidae Family and 01 species of each Botiidae,Siluridae, Bel itoridae, Cobitidae, Gobi idae, Bel itoridae, Notopteridae,, Al l idae,Sisoridae, Claridae,Heteropneustidae,Siluridae,Mugilidae and Anabantidae family. Further Sorenson’s value of data is 0.72 which shows more than fifty percent and less than hundred percent similarity of the species in three different habitat of aquatic body of the Bokaro District. Data also shows that in out of 42 species 35 species is in LC category,06 are under NT category and 01 species consider under DD in IUCN Red list.
Present study was conducted to document the lcthyofaunal diversity of Bokaro district(Jharkhand) during Pre-monsoon season. Survey was made on Hill stream area, Reservoir and River area of Bokaro district (Jharkhand) during February to April 2017. Survey was made for eighteen freshwater fish species among which five different orders and ten families have been documented during Pre-monsoon period. Out of the total eighteen species of fishes, nine species belonging to family Cyprinidae and one species each from Notopteridae, Botiidae, Channidae, Gobilidae, Anabantidae, Claridae, Mastacembelidae and Bagridae family. Present study clearly shows that the Cyprinidae family of fishes are dominant fish species in aquatic body of Bokaro district. Out of eighteen species of fishes, one species of Anabantidae family is in under IUCN- VU category, where others are IUCN- LC category except one species of Botiidae family is in NBFGR-VU category. Further, study with more no. of sample and diverse population is needed for species level identification throughout the year.
