"The captain, a Russian citizen named as Aleksandr Matveev, was later sentenced to four months in prison and fined Rp200 million (£10,800) after being found guilty of illegal fishing. The other Russian and Ukranian offers were deported to their home countries."

That seems an extraordinarily light punishment for an operation that looted tens of millions of dollars worth of fish and caused untold harm along the way. I can't imagine would-be pirates being much deterred.
