Monsters of the deep
Illicit trawlers are devastating fish stocks and abusing crews.
How can they be stopped?
“Consider the subtleness of the sea,” warned Herman Melville in “Moby Dick”; “how its most dreaded creatures glide under water...treacherously hidden beneath the loveliest tints of azure.” Nearly 170 years later, another marine horror is just becoming visible. Satellite and other imagery has revealed “dark fleets” of fishing boats that turn off their transponders and plunder the ocean’s bounty. Illegal, unreported and unregulated fishing accounts for a staggering 20-50% of the global catch. It is one reason fish stocks are plummeting: just a fifth of commercial species are sustainably fished. Illegal operators rob mostly poor coastal states of over $20bn a year and threaten the livelihoods of millions of small fishermen. North Korean coastal waters have been so pillaged that its fishermen have to motor their rickety craft far out into stormy seas to fill their nets. Thousands have drowned.
subtleness 是subtle的名词形式，subtle 指"机智的，巧妙的"，当然它还有"微妙的"之意
A huge amount of illicit fishing happens on licensed boats, too. They might catch more than their quota, or falsely declare their catch as abundant albacore tuna instead of the more valuable bigeye. In port fisheries inspectors are always overstretched. If an operator is caught, for instance, fishing with too fine a net, the fine and confiscation are seen as a cost of doing business. Many pay up and head straight back out to sea.
