Abstract:

Due to the influence of many independent variables, productivity being a dependent variable, exhibits wide variation. In the present communication the relationship between farm size and aquaculture productivity has been reported. Data from 79 representative farms collected from July 1998 to July 1999 at the Eluru and Kaikalur blocks of the Kolleru lake area have been considered. The size of farms ranges between 0.8 to 60 ha whereas productivity ranges between 10 to 14 t·ha-1·yr-1 . Positive correlation between carp productivity and area of the farms has been found (r = 0.52). The coefficient of determination (R2 = 0.28; P<0.001, N = 79) indicates that 28% of the total variability in carp productivity in the two blocks is explained by farm size only. The findings may be justified by the fact that large sized farms are more economical and conducive for better efficiency than small sized farms considering that all the technical advantages applicable to small sized farms are also open to large sized farms and not the other way around. It is claimed that, large farms enjoy economies of production, management, finance and marketing. These economies help in reducing the cost of the farm and in increasing its efficiency. All the scale operations contributing to the above-mentioned relationship are discussed in details in this paper.
