found were between catch per unit area/effort and density of fishers, which varied
geographically. They then went on to develop a Bayesian network model (see
Box 5.4) to investigate the factors affecting equity of income distribution and
compliance with rules (both likely to be important components of social
sustainability), as well as CPUE (see the table below).
Factors found to be important in a preliminary analysis of sustainability of
artisanal fisheries.
Note
: Equity is the evenness of distribution of fishing yields (high or low). CPUE change is whether
the CPUE is declining or not, and compliance is a subjective measure of the level of compliance
with the management rules (high/low). Management type is either government or co-managed/
community-managed. The number is the rank order of importance in determining a positive out-
come for a particular sustainability indicator (e.g. conflict resolution has the highest effect on
equity). Relationships are positive unless otherwise noted (e.g. more gears
higher equity, more
effective control and surveillance
higher probability of CPUE being stable or increasing).
