A livelihood is sustainable ‘‘when it can cope with and recover
from stress and shocks and maintain or enhance its capacities and
assets both now and in the future, while not undermining the
natural resource base’’ [15,20]. The concept of sustainability includes
ecological, social, economic and institutional components [21,22]
which are all important to fishery [23], and thus looks broadly at
ecological sustainability, while the livelihoods approach addresses
socioeconomic and community sustainability [24].
