An analysis of production factors in carp farming in Andhra Pradesh, India

Abstract

Three major carp species, viz. catla Catla, Labeo rohita and mrigal Cirrhinus mrigala, are farmed in polyculture systems in the southern state of Andhra Pradesh, India. A survey of 189 carp farms was undertaken, and principal component analysis was used to assess the relationships between farm inputs and fish yield. Model results exhibited a strong relationship of yield with the stocking density of all three major carp species.
