This study was conducted in the south-western part of Bangladesh. The information was collected through interviewing of 75 prawn farmers. Average stocking density and production in Khulna and Bagerhat region using wild post larvae (PL) were 7000 PL, 6750 PL and 167 and 159 kg/acre respectively and survival rate varied from 45 to 90 and 40 to 85% respectively. For hatchery produced PL the average stocking density, survivability and production in Khulna and Bagerhat region were 9000 PL, 53% and 124 kg/acre and 9250 PL, 55% and 120 kg/acre respectively. Results of the study identified net profit of 25924 BD taka in Khulna and 17742 BD taka in Bagerhat by using wild PL as well as 10581 BD taka in Khulna and 12163 BD taka in Bagerhat as a net profit by using hatchery PL. Lack of finance and appropriate technology, lack of proper feeding, scarcity of quality hatchery PL, scarcity of wild PL according to demand, diseases and inadequate extension work were major problems of prawn culture.Pages: 137-141 | 1226 Views 46 DownloadsDownload Full Article:
