Low- body dussumieria [2] ( lat. Dussumieria elopsoides ) is a species of ray-finned fish of the herring family. These marine pelagic fish live in the subtropical waters of the Indian-Pacific region between 36 ° C. w. and 19 ° s w. and between 32 ° c. d. and 164 ° c. The body is spindle-shaped, covered with cycloid scales , the head is bare. The maximum length is 20 cm. They are found at a depth of up to 50 m. They feed on plankton . They are the subject of commercial fishing [1] [3] [4] .

Low-bodied dussumeria lives in the Indian Ocean from the Suez Canal and the Red Sea , along the coast of Pakistan , India and Malaysia to the western Pacific Ocean ( China and the Solomon Islands ) [3] . This marine pelagic fish is found in coastal waters [1] .
A sweeping, slightly flattened laterally body is covered with large cycloid scales ; the body height is 4.6–6.3 times less than the length. The belly is round, the keel is absent (at the base of the ventral fins there is one keeled scale in the shape of the letter W). The dorsal fin is located closer to the caudal fin than to the snout. Anal fin small. The ventral fins are opposite the dorsal fin. The caudal fin is forks. The length of the small head is 4 times less than the length of the body and 3.6 times the length of the snout. The length of the upper jaw of the large mouth is approximately 80% of the length of the snout; the jaw slightly does not reach the edge of the eye orbit. The maxillary bone is rectangular, forms a characteristic shape of the mouth. The jaws, vomer, tongue and pterygoid have small teeth. Gill stamens are lanceolate. There is a thin fat eyelid. In the dorsal fin 16-18 rays; in the anal 14-18; in the chest 14-15; in abdominal 8; stamens on the 1st branchial arch 21–32; 42–46 scales in the lateral line; rays of the gill membrane 13-17. The dorsal surface is gray-brown, the head and sides are light brown, the belly is silver, the dorsal and caudal fins are light brown, the anal and ventral fins are whitish. The strip along the posterior edge of the scales is absent [4] [3] .
The maximum length is 20 cm [1] .
These motile fish make short migrations within the area of their habitat. Reach puberty with a body length of 13-15 cm at the age of about 2 years. Life expectancy is estimated at 4-5 years. In the spawning herd, fish are predominantly 2-3 years old and 14-17 cm in size. The diet of low-body dussumeria consists of zooplankton .
These fish are subject to local fishing. The International Union for Conservation of Nature has not yet evaluated the conservation status of the species.
