Based on qualitative fieldwork, this study analyses reasons and outcomes of fishers’ migration in Bangladesh. The results show that fishers’ livelihoods are characterised by a series of vulnerabilities and endemic poverty contributing to their migration decisions. However, fishers also migrate pro-actively to enhance their capacities and explore opportunities. The outcomes of migration are highly diverging: while for poorer fishers, migration is a way of coping with shocks, better resourced fishers can use it for asset accumulation. The importance of migration for their livelihoods and emerging networks across space generate forms of translocal households that coordinate their activities over long distances.
