In the Black Sea, their diet contains sprats, anchovies, and pipefish. The recipe is often mistranslated into English, with anchovies being substituted for sprats. Also, small herrings ("Clupea harengus") may be used instead of sprats. One of Estonia's national dishes is (Baltic dwarf herring), along with sprats. Clupeichthys is a genus of sprats, herring-like fishes, that occur in rivers in Southeast Asia. Like most forage fishes, sprats are highly active, small, oily fish. They are both fond of each other, and share a love for pickled sprats. Smaller, or "fun-sized" variants of the chocolate fish are colloquially referred to as "sprats". In the following December large numbers were taken together with sprats at Torquay. Fishing for sprats could be a relatively worthless business. Young sprats are commonly known as brisling. Clupeoides is a genus of sprats that occur in rivers in Southeast Asia. True sprats belong to the genus "Sprattus" in the family Clupeidae.
