摘要

That's the staggering number of sharks purportedly killed each year, according to savingsharks.com, shark-water.com, the nonprofit WildAid and Anderson Cooper's 360° blog. The number has become a rallying point for ocean advocates, but is it true? Not quite. Without a doubt, sharks are in serious trouble. A 2006 research paper published in the journal Ecology Letters found that the amount of shark meat in the fin trade is three to four times higher than shark catch globally reported and that current catches are exceeding maximum sustainable yields. Researchers estimated that between 26 million and 73 million sharks are killed each year for their fins alone. A substantial amount of catch is illegally taken and unreported, and therefore unregulated, say the authors. Sharks are especially vulnerable to overfishing given their life history: They grow slowly and produce few young.
