Similar to on-farm, non-farm, and off-farm diversification, in
marine fishing, a distinction must be made between ‘‘withinfishing’’ (fishing with different gears, adapted to target species)
and ‘‘outside-fishing’’ diversification, such as agriculture or the
provision of specialized services and labor [32]. Diversification is
a household strategy to cope with risks. Diversification, defined as
the process in which people construct a diverse portfolio of
activities and social support capacities in their struggle to survive
and to improve their standard of living [33], is often fundamental
to achieving sustainability in fisheries [24], and is potentially an
important strategy for dampening the effects of catch variability.
