Summary Gibel carp Carassius gibelio (Bloch) was first introduced into fish ponds and small lakes of Estonia in 1948–49, and first detected in Estonian brackish waters (Gulf of Riga) in 1985. Since the mid-1990s, the species has spread along the entire Estonian Baltic coastline. Growth rate in the brackish water population does not differ much from freshwater populations, but the freshwater populations are gynogenetic (or show high dominance of females) in contrast to the Baltic Sea population, which presents a normal sex ratio. The recent explosion of this species in the Baltic Sea could be explained by unusually warm summers during the 1990s and by the low abundance of predatory fish.

Life-history traits and potential invasiveness of introduced pumpkinseed Lepomis gibbosus populations in northwestern Europe (2009, background): “Sex ratio has been found to be a distinguishing, environmentally-linked character in another species invading northern Europe, the gibel carp Carassius gibelio (Vetemaa et al. 2005).”
Pathways of ornamental and aquarium fish introductions into urban ponds of Epping Forest (London, England): the human vector* (2005, background): “Threats to crucian carp have been exacerbated by its physical similarity to the brown variety of goldfish, which has been mistaken for crucian carp during fish transfers in the UK (North, 2000; Wheeler, 2000) and fisheries catches elsewhere (Vetemaa et al., 2005).”
To be, or not to be, a non‐native freshwater fish? (2005, background): “After establishment, a lag phase in expansion occurred in some systems, followed by invasions of all suitable aquatic environments (e.g. Vetemaa et al., 2005).”
