Carassius gibelio in Greece: the dominant naturalised invader of freshwaters

“…This practice was also adopted in many lakes of northern Greece, where landings practically depend on C. gibelio and at the same time a dramatic decline of all other commercially valuable species is evident. Another ecologically sound measure would be the exploitation of fully mature C. gibelio for the extraction of their pituitaries which have been proved valuable to the induction of spawning in cyprinids [potency and hormonal compatibility were recently demonstrated in common carp (Kosti et al 2008;Perdikaris et al 2007) and in goldfish (Vavatsikos 2009)]. Other options such as small scale fish meal, on-farm fish feed, livestock and pet feed and fish Fig.…”

Alien fish and crayfish species in Hellenic freshwaters and aquaculture

“…From an aquaculture point of view, this trash fish could be exploited as a pituitary donor for the artificial reproduction of cyprinids as its pituitary potency and hormonal compatibility were recently demonstrated in C. carpio (Perdikaris et al. 2007; Kosti et al. 2008) and in C. auratus (Vavatsikos 2009).…”

“…This species is regarded to be self-recruiting in the north-eastern part of the country (Economidis et al 2000a), particularly in the Rivers Evros, Strymonas (artificial Lake of Kerkini) and River Kompsatos (Economou et al 2007), but there is debate because the original distribution pattern is 'masked' by introductions, translocations, complex modes of reproduction and species confusion (Kottelat & Freyhof 2007). From an aquaculture point of view, this trash fish could be exploited as a pituitary donor for the artificial reproduction of cyprinids as its pituitary potency and hormonal compatibility were recently demonstrated in C. carpio Kosti et al 2008) and in C. auratus (Vavatsikos 2009).…”

Status and development prospects for indigenous freshwater finfish and crayfish farming in Greece

“…Standard hormone mediated reproduction and fry production (discussed in detail in Paschos 2004; Kosti et al. 2008) are routinely carried out in the Department of Aquaculture and Fisheries, Technological Educational Institute of Epirus (north‐west Greece), in the state carp hatchery of Psathotopi (western Greece) and in the Municipal Hatchery of Ioannina Lake Dimotiki Epihirisi Limnis Ioanninon S.A. (D.E.L.I.…”

“…Carassius gibelio (Bloch, 1782)), hybridization and introgression with farmed stocks and closely related species (e.g. many farmed stocks in Eastern Europe belong to the species Cyprinus rubrofuscus Lacepède, 1803;Kottelat & Freyhof 2007).Standard hormone mediated reproduction and fry production (discussed in detail inPaschos 2004;Kosti et al 2008) are routinely carried out in the Department of Aquaculture and Fisheries, Technological Educational Institute of Epirus (north-west Greece), in the state carp hatchery of Psathotopi (western Greece) and in the Municipal Hatchery of Ioannina Lake Dimotiki Epihirisi Limnis Ioanninon S.A.
