Abstract

This study present an economic analysis of white shrimp farming at different size of ponds. Forty white shrimp farms selected from two different size of ponds. The sample sizes then were categorized into two scales small size was 400 – 600 m2, and large size was 1000 m2. Two sets of variables were carefully determined. The first set was the biological, survival rate and feed conversion ratio whereas the second set was the economic type which consisted on input intensity. Multivariate statistical concepts were applied which included multivariate analysis (MANOVA) and principle component analysis. The Cobb-Douglas production function was further used to study the current status of white shrimp production system. As a result indicates that there was significant effect on small and large white shrimp farming system by using the multivariate input variables. The principal component analysis showed that large ponds farm had higher intensity in overall input compare with small pond. Finally, the Cobb-Douglas production function analysis indicated that unit of the net return was strongly determined by the input intensities of labor. The analysis also reported an increasing return to scale.
