Summary of overall effects and temporal heterogeneity in the mean difference of fish biomass among zones of the Saba Marine Park.

Spanning five surveys (1991, 1993, 1994, 1995, 2008) of herbivorous and carnivorous fish families at depths (5 and 15 meters) among zones closed and open to fishing, the significant p-values for overall effect of zoning (Z, df = 4, α = 0.0125, after Bonferroni correction for multiple comparisons, k = 5) and variability across survey years (χ2, df = 4, α = 0.05, [40]) are indicated in bold. Underlying data for 1991–95 sourced from Polunin and Roberts [22], Roberts [23] and Roberts and Hawkins [24].
