First global map reveals rapidly shrinking hotspots for tuna, marlin, swordfish; Diversity has declined by up to 50% over 50 years due to fishing

A study released in Science reveals a striking downward trend in the diversity of fish in the open ocean – the largest and least known part of our planet. Teasing apart the effects of climate change and fishing over the past 50 years, the authors show a clear link to overfishing and highlight a surprising global pattern of open ocean hotspots - areas with predictable congregations of tuna, marlin, swordfish, and other ocean predators.

In October 2005, Ransom Myers was chosen by Fortune magazine as one of the world's top ten movers and shakers: people who will change the way the world operates over the next 75 years. The prominent business magazine predicted that Myers' work on fish population dynamics and the depletion of sharks, tuna and other fish species will foster "new and better ways to husband the wealth beneath the sea."
