Summary statistics for fish biomass (grams per 100 m2), fish density (fish per 100 m2) and average fish weight (grams per fish) for different fish groups across reef-surveys allocated to two categories of protection effectiveness against fishing.

Snappers (SNP), groupers (GRP), highly valued commercial species (COM) and parrotfishes (PAR). n- number of surveys in which the fish group was present; Percent – percentage of surveys in which the fish group was present; sd-standard deviation. Only data of surveys under the Unprotected/Unknown protection status (left columns) were used in correlation analyses with human population size. See Table S1 for details on species making up these fish groups.
