6. An Economic study on Vietnam Koi farming in some selected areas of Muktagacha Upazila in Mymensingh district

Abstract

Vietnam Koi has opened up a new horizon of pond culture in Bangladesh. In Bangladesh, the importance of this fish in meeting the protein needs of the growing population is enormous.

Farmers prefer it as a business because of its strong growth and productivity. It was necessary to do an economic analysis on Vietnam Koi aquaculture in order to do so. The cost, returns, and profitability of Vietnam Koi production were estimated in this study, as well as the major variables influencing the gross return on Vietnam Koi farming. For this, 40 farmers were selected randomly from three villages namely Polsha, Sayedgram and Baniakazi at Muktagacha Upazila under Mymensingh district. Both tabular and functional analyses were done to address the objectives of the study. The average total cost of Vietnam Koi production per hectare was calculated Tk.12,90,498.19. The total return of Vietnam Koi per hectare was estimated as Tk.19,92,413.50. Gross margin and net return per hectare were estimated as Tk.7,84,238.11 and Tk.7,01,915.31 respectively. In the research area, the production of Vietnam Koi was determined to be profitable. Cobb-Douglas production function was used to estimate the specific effect of factors on gross return. Most of the factors included in the model were considerably effective on the production of Vietnam Koi, according to the Cobb-Douglas production function model. So there is a positive effect of key factors in the gross return of Vietnam Koi. Out of nine variables, five of them (human labor, fingerling, feed, fertilizer and pesticide) had significant effect on returns of Vietnam Koi production. In conclusion, the study found that Vietnam Koi fish farming was profitable in the research area.
