The presence of Lactobacillus in the gastrointestinal tract is considered beneficial in a wide range of hosts. In fish, the presence of Lactobacillus has been reported mainly in salmonids and marine fish. Few studies have described lactic acid bacteria in other freshwater fish. In particular, there are no reports on the presence of Lactobacillus in the intestines of young and adult freshwater fish inhabiting river environments and from fish reared in aquaculture units with water recirculation systems. In this study we show that various species of Lactobacillus are present in relatively high number in the intestines of fresh water fish from a river, especially in the warm season but in low numbers in the intestines of farmed fish reared in a recirculation system in warm water. Lactobacillus are reported for the first time from the intestines of Anguilla anguila, Perca fluviatilis, Scardinius erithrophthalmus, Gymnocephalus cernuus, Alburnus alburnus, Blicca bjoerkna, Leuciscus cephalus, Silurus glanis and Clarias gariepinus. The two first species, commonly named eel and perch and the last one are highly valuable species for aquaculture. Additionally, improved methods for storage and bacteriological analysis of fish intestinal content are described.
