Very little is currently known about the biology of the Skadar gudgeon (1). However, it may be similar to that of the gudgeon (G. gobio), which matures at two to three years old and spawns between May and June. The eggs of G. gobio hatch in about 15 days (4).
The diet of Cyprinidae species is usually quite diverse (3). Like G. gobio, the Skadar gudgeon is likely to feed on a variety of insects, crustaceans, molluscs and occasional plant material (4). Instead of jaw teeth, most members of the Cyprinidae family possess a pair of enlarged bones in the throat, with structures known as ‘pharyngeal teeth’ which are used to process food (3).
The Skadar gudgeon is likely to be mainly solitary, although it may sometimes come together in small shoals (4).
