Amblygaster sirm

Amblygaster sirm, the spotted sardinella, also known as the northern pilchard, spotted pilchard, spotted sardine, and trenched sardine, is a reef-associated marine species of sardinellas in the herring family Clupeidae. It is one of the three species of genus Amblygaster. It is found in the marine waters along Indo-West Pacific regions from Mozambique to the Philippines, and towards north Taiwan and Japan to the far east of Australia[2] and Fiji.[3] It is a widely captured commercial fish in Sri Lanka, where the fish is known as "Hurulla" in Sinhala language.[4]

The distinctive feature of spotted sardinella from other two relatives is the presence of 10 to 20 golden spots along the flank. The color of spots may change into black after preservation. Belly is less rounded and scutes are not prominent. The fish feeds on minute organisms like copepods, larval bivalves and aquatic gastropods, and dinoflagellates like Peridinium and Ceratium. The fish is used in tuna fishery as a live or dead bait.[5][6]
