The deep sea fishing business in Taiwan is facing a crisis because of precipitous drops in its squid and saury catch . . . The main reason for the fall is that Taiwanese fishing boats have been unable to secure decent squid catches in the southwestern Atlantic Ocean near the Falkland Islands and Argentina — the world's main squid fishery. It is unknown whether the precipitous plunge is just a cyclical change or a warning sign that marine resources are drying up.
As I've pointed out before, data-blind fishing is a risky business.
