Thailand: Fish farms play an important role for communities near Ko Yo (Yo Island), Thale Sap Songkhla (Songkhla Lake). Songkhla was the seat of an old Malay Kingdom with heavy Srivijayan influence. In ancient times (200 CE - 1400 CE), Songkhla formed the northern extremity of the Malay Kingdom of Langkasuka. The city-state then became a tributary of Nakhon Si Thammarat, suffering damage during several attempts to gain independence.
