Where the Shark and the Snapper Roam

“two marine scientists compared the fish communities of the main Hawaiian Islands, where people live, with communities near the uninhabited northwestern Hawaiian Islands. To their surprise, they found that where there is no fishing, top predators ruled the waves; in the uninhabited areas, top predators made up more than 54 percent of total fish biomass compared to just three percent in areas near human settlement. Later, a series of expeditions to remote islands of the Pacific have confirmed that this pattern of seeing more top predators than prey can be found on other uninhabited reefs. On Kingman Atoll, for example, sharks and large snappers and jacks represent 85 percent of the total weight of fishes!”
