Results of PermANOVA comparing fish biomass, fish density and average fish weight for different fish groups between reef-surveys in sites with Full/partial protection against fishing and those in sites with Unprotected/unknown protection status.

Snappers (SNP), groupers (GRP), highly valued commercial species (COM) and parrotfishes (PAR). To control for spatial effects, permutations were carried out within AGRRA sampling batches (see Table 1). Results of Levene’s test for homogeneity of variance are also shown for each comparison. Bold font indicates significant values at a nominal level of 0.05. See Table S1 for details on species making up these fish groups.
