Ecosystem-Scale Effects of Nutrients and Fishing on Coral Reefs
Figure 3
The effects of fishing on top predators, herbivores, large- and small-bodied fish biomass. Fishing resulted in exponential declines in top predator ((a) ,; permutation test: ) and large-bodied fishes ((b) , , permutation test: ) biomass. Herbivores ((c) , , permutation test: ) and small-bodied fishes ((d) , , permutation test: ) biomass declined linearly with fish catch. Herbivore biomass only declined when top predator biomass was less than 0.81 mT/ha (95% CI: 0.16, 1.44) ((e) , , permutation test: ). Small-bodied fish biomass only declined when large-bodied fish biomass was less than 2.04 mT/ha (95% CI: 1.16, 2.90) ((f) , , permutation test: ).
