 ABSTRACT

The present study was carried out to investigate abiotic factors on fish growth in micro-water sheds of Dungarpur district. The average water quality parameters of all the selected micro-watersheds were significance between the water bodies. It indicated that the water of selected micro-water sheds were congenial and moderately productive from the fisheries point of view. The physico-chemical and primary productivity revealed a significant impact on fish growth parameters such as gain weight, length gain and SGR. Comparatively higher net weight, net length and SGR were recorded for Catla (1103.3 gm) followed by than rohu (932.16 gm) and Mrigala (830.10 gm). The specific growth rate of catla was (2.16 %) in Valota followed by Khaliya (2.09 %). The lower SGR was noticed in Negala (1.99 %) followed by Kundi-Ka-Naka (2.00 %). The average primary productivity fluctuated between the selected micro shed in southern Rajasthan region of Dungarpur district.

Key words: Abiotic factors; Primary productivity; Specific growth rate; Dungarpur.
