Some scientists working in the region disagree with the piracy hypothesis, though, saying the increased catches have more to do with environmental changes associated with warmer waters that shifted to East Africa around the time of the reported catches.
Even if the piracy story is not true, it should be true. During WWII, when fishing boats and their crews were needed for the military rather than seafood markets, fishing after the war was over also showed improvements. That not mean piracy should be a conservation goal. Nor should war. However, if we left the ocean alone, fisheries would likely rebound.
