Fisheries and Hydrography of Baitarini at Jajpur, Odisha, East Coast of India

Investigation on the hydrography and fish fauna were undertaken from a period of February to September, 2012 at selective locations in river Baitarini, Jajpur. Twenty eight species of fish belonging to six orders, eleven families and nineteen genera were collected. Order Cypriniformes was most dominant constituting 33.33% followed by Siluriformes (30.3%), Perciformes (12.12%) and others like Mugiliformes, Osteoglossiformes and Synbranchiformes. Of the total fish species Catla catla, Labeo rohita, Labeo calbasu, Ompok pabda, Puntius sophore, crustaceans (Macrobranchium rosenbergii and Macrobranchium malcolmsonii) were abundantly found. Results of hierarchical clustering using group average linking for water quality parameters revealed two main clusters of stations based on similarities/dissimilarities of physicochemical hydrological parameters.
