This does not just affect sharks, but the problem is that with worldwide marine pollution and overfishing, fishermen themselves describe today's fisheries as only being good for fishing "three days on and two days off." "All kinds of fish are getting scarcer," they say, "and we can't catch enough however hard we try."
問題是，不只是鯊魚，由於世界性的海洋汙染與濫捕，漁業界自己形容今天的漁業資源已是三天打漁，兩天曬網，「什麼魚都在減少，怎麼努力抓都抓不到。」
