Anchovy Sprat
Clupeonella engrauliformis
Anchovy sprat, Clupeonella engrauliformis, is a species of fish in the family Clupeidae. It is one of several species of Clupeonella found in the Central and Southern Caspian Sea. It lives pelagically in the central and southern parts of this brackishwater lake. It is typically 12 cm (4.7 in) long, and up to 16.5 cm (6.5 in) maximum. It may be found down to a depth of 78 m (256 ft).
The achovy sprat was first described by ichthyologist N. A. Borodin in 1904 under the name Clupea engrauliformis. The holotype is 124 mm in length, was caught near Cape Buynak in the Caspian Sea and is stored in the Zoological Institute of the Russian Academy of Sciences.
