detention," he said in a news conference.

The fishing boat Hoshin Maru No. 88 from Toyama Prefecture and all 17 men aboard were seized June 1 in waters east of the Kamchatka Peninsula for allegedly violating fishing regulations.

Russian authorities still have the boat and are continuing to interrogate the crew.

The Russian border patrol said it seized the boat because it had caught more fish than it declared and was hunting for expensive blueback salmon without Russian permission.
