A Royal Thai Navy patrol seized a Vietnamese fishing boat found illegally trawling Thai waters.
18 crewmen were arrested when the boat, registered only as CM91711TS, was impounded April 1, 130 nautical miles off Koh Chuang. Two other Vietnamese boats escaped.
In the hold of the seized boat was a dolphin on ice, fueling fears the Vietnamese were fishing for protected dolphins.
Soldiers hold up dolphin fins found in the hold of the foreign fishing boat.
