Growth performance and feed conversion efficiency of Siberian sturgeon (Acipenser baerii) at mid-elevational zone

Abstract

The study assessed the growth performance, and feed conversion efficiency of adult Siberian sturgeon (Acipenser baerii; N=15) reared on-farm. It was intended to establish a baseline information for rearing sturgeon at a lower elevation at 500 masl. The sample used was a four years old cohort acquired from the Rainbow Trout Breeding Centre, National Research and Development Centre for Riverine and Lake Fisheries, Haa. The sample was maintained in a circular tank with a flow-through water system at a temperature varying between 14.00 to 24.30°C. The growth performance was assessed monthly. The specific growth rate and feed conversion ratio recorded at the mid elevation of about 500 masl was 0.2% day^-1and 3.12, respectively.
