On 30 May 2011, Rear Admiral Pradit Sirikup (Commandant of Navy Force) and Commander Master Niwat Jit Pool of the vessel Luang Narathiwat had visited Hai Phong Port of Socialist Republic of Vietnam.
On their way back to Sattahip Bay, they found a suspicious fishing boat located about 54 miles from Joh Juang, Saemeasan Sattahip Bay, Chonburi.
The 12-metre-long and 3-metre-wide blue saloon boat was stopped for inspection and questioning, Admiral Pradit said adding that the ship was a type of fishing boat for squids.
Upon searching, there were altogether ten people in the boat crew including one 35-year-old boat captain and nine teenagers.
In addition, Thai authorities also discovered fishing equipment on the boat including electrical fishing devices along with traces squid and dried fish.
The Vietnamese Captain Dang Quang Den confessed that his ship departed from Ca Mau province of Mekong Delta region in Vietnam.
There are three other ships in the same fishing network, Captain Dang said.
Captain Dang explained that his ship invaded Thai water because there are various types of squids and fish of large sizes in these areas.
Large and fresh squids and fish are more expensive especially during the upcoming Chinese festival, he said adding that selling them would be very profitable for his business.
Rear Admiral Pradit Sirikup stated that based on the meeting discussion with the Social Republic of Vietnam, Thai authorities will allow Vietnamese fishing boats to enter Thai sea provided that the fishing network consists of a large number of mother vessels with permits.
The small blue saloon boat has violated the agreement, Admiral Pradit said.
However, in order to keep the relationship between the two countries, the fishing saloon was forced to leave Thai sea immediately with a warning along with other boats in their network, Admiral Pradit concluded
