Economic Analysis of Modem Technologies in Shrimp Farming: A Case Study from Karnataka State

摘要

The modern technologies such as air oxi tubes, pond lining and biofloc technology have evolved as a feasible solution to solve predicaments such as poor feed conversion ratio and undesired concentration of dissolved oxygen. The study attempts to quantify the economic benefits realized by shrimp farmers on adoption of modern technologies. For the study, three innovative farmers who have adopted modern technologies were selected from Udupi district of Karnataka and their performance was compared with ten farmers practicing conventional method. The shrimp farming with modem technologies required an initial capital investment of Rs. 13.06 lakh which is 91.63 % higher compared to conventional method (Rs.6.82 lakh). The cost benefit analysis of shrimp farming indicated that farmers realized net returns of Rs. 154.79 kg~(-1) which is 54.83% higher compared to conventional method (Rs. 99.97 kg~(-1)). The economic benefit of modem technologies per acre per year came to Rs. 32.64 lakh reflecting the worthiness of modern technologies. Adoption of such technologies on wider scale will have a win win situation i.e., generating enough returns on one hand and meeting exacerbating demand on other hand.
