In Thailand, as in the other parts of its wide range (Africa, Aus- 

 tralia, India, East Indies, Malay Peninsula, Philippines, Indo-China, 

 China) , this fish occurs in both salt and fresh water. It is the com- 

 monest and most generally distributed of the Gobiidae in the coastal 

 waters of Thailand, being found along the entire coast of the Gulf 

 of Siam and in the lower courses of all the rivers. Waters in which 

 the species has been actually collected are: Menam Chao Phya at 

 Bangkok, Bangsorn, and Nontaburi: Meklong at Rajaburi; Tale Sap 

 in inner and outer lakes ; Patani River ; Bangpakong River ; at mouth 

 of Chantabun River, in estuary of the Chantabun River at Lem Sing, 

 in Krat River at Ban Taeng, in Klong Raibon, and in Wain River at 

 Paknam Wain. The point farthest inland where the fish has been 

 found is Ban Pan in the Sikuk River, Central Thailand. 



The maximum size observed in Thailand is about 30 cm. In some 

 other countries a length up to 45 cm. is reported. 



The eggs as laid are attached to the lower side of rocks and timbers, 

 in streams, klongs, and lakes. 



Owing to its considerable size and abundance, this goby locally is 

 caught and consumed in large quantities, and is economically the most 

 valuable of the local gobies, although in flavor and texture of flesh it 

 does not have a high rank. 



The fish bites freely at almost any kind of animal bait, and is caught 

 in large numbers by anglers. It is also taken with traps, seines, and 

 the various kinds of bag nets used in coastal waters and lower courses 

 of rivers. 



The usual vernacular name given to this fish is pla hu. In the 

 Menam Chao Phya pla bu sai (sand goby) and pla hu tong (golden 

 goby) are heard. A name in use on the Meklong at Rajaburi is />/« 

 hu hin (rock goby). In the inner lake of the Tale Sap the fish is 

 called pla sai (sand fish), while at Singora, at the outlet of the Tale 

 Sap, a name reported is pla luh sai (sand-fruit fish).
