RESULTS AND IMPACTS

Extension Trends of the Technology


Until the end of 2005, nobody paid attention to the activities in Chandpur. Farmers started showing interest only when it was demonstrated from trials with farmers and proved to be economically profitable at the household level. Once proved, number of families interested increased gradually and so the number of cages (Fig. 3). Various social sects such as, other businessmen, unemployed youth groups, primary school teacher, started involving in the venture. Thus at the end of 2006, a total 276 cages were functioning in Dakatia river and in 2007 the number increased to 578. Especially, after the involvement of Bangladesh Army, mass media highlighted and many more people came to learn about the activities and many people started getting involved indiscriminately and remarkable competition was observed for placing the cages in the rivers. At the end of 2008 the number raised to 1,580 and in following two years (2009 and 2010) the figure raised to 2,375 and 3,241 respectively and at the moment there are 3,510 cages in the river Dakatia alone in Chandpur.

It was also possible later in October 2006 to transfer the cage culture technology to nearby district i.e. Laxmipur only after having success in the district where training center was located. A total of 78 cages were introduced first in a canal of Meghna river near Barishal-Laxmipur steamer Ghat. In the following year the number increased to 273 and then in 2008 it reached to 550 covering 2 km canal leaving only one side for navigation. However, during the following years the numbers of cages at Laxmipur have declined because some poor farmers could not continue supporting the feeding cost (Table 1 and Fig 4).
