Esox cisalpinus was distinguished from Esox lucius (northern pike) and described scientifically as a new species in 2011 independently by two research groups. The description by Bianco & Delmastro was printed earlier, [4] and the name Esox cisalpinus is therefore accepted, whereas the alternative name published somewhat later by Lucentini et al., Esox flaviae, is considered a junior synonym.

Its body outline resembles that of the northern pike (E. lucius). Unlike northern pike, however, the opercles and cheeks of chain pickerel are entirely scaled. [5] It may reach up to 78.7 centimetres (31.0 in) long only on rare occasions. [8] The average size for chain pickerel, however, is 24 in (61 cm) and 3 lb (1 1/2 kg).
