Production Performance of White Fish in Two Different Culture Systems in Patuakhali, Bangladesh

Abstract

The present study was carried out to compare the production performance of white fish from traditional and modified traditional culture system of three upazila in Patuakhali district. For the research work, 10 traditional and 10 improve traditional farmer was selected from each Upazila. From the study average pond size of traditional farmers of Patuakhali sadar, Galachipa and Mirzaganj was found 4.56 ±0.29 decimal, 5.58 ±2.49 decimal and 4.6 ±1.32 decimal respectively and improve traditional farmers was 5.64 ±2.18, 5.65 ±2.18 and 5.24 ±2.73 decimal respectively. Average stocking density of traditional farmers was 207 ±57, 219 ±38 and 227 ±56 fingerlings/ decimal and that of improve traditional farmers was fixed which were 55 fingerlings/ decimal in Patuakhali sadar, Galachipa and Mirzaganj respectively. Average survival rate of traditional farming system was found as 62±6.21%, 65±5.25% and 61±11.25% respectively in Patuakhali sadar, Galachipa and Mirzaganj and that of improve traditional farming system was found as 76±5.16%, 80±4.97% and 77±5.87% respectively. In Patuakhali sadar upazila, average production of traditional farmer was found 4.71±0.7652 kg/decimal and that of improve traditional farmer was 10.67±0.8830 kg/decimal. In Galachipa upazila, average production of traditional farmer was found 4.47±0.7365 kg/decimal and that of improve traditional farmer was 10.66±0.3342 kg/decimal. In Mirzaganj upazila, average production of traditional farmer was found 4.47±0.4127 kg/decimal and that of improve traditional farmer was 10.43±0.4785 kg/decimal. The benefit cost ratio of traditional farmer: improve traditional farmer = 1:4.24. From the result it can be assumed that utilization of improve technology can increase the fish production two and half time more than that of current production. This will also help us to get back our country tradition “Mase Bhate Bangali”.
