Abstract: To understand the intestinal flora composition of four types of common freshwater fish in Dongping Lake of Shandong province, aerobic or facultative anaerobic bacteria of intestinal flora in Ctenopharyngodomi dellus, Hypophthalmichthys molitrix, Cyprinus carpio haematopterus and Carassius auratus were isolated and identified, with the quantity and composition of intestinal flora being analyzed. The results showed that in this study Hafnia, Xenorhabdus, Ameromonas, Citrobater, Bacillus, and Strooptococus were common to each type of fish, and Cyprinus carpio haematopterus and Carassius auratus contained appropriate quantity of intestinal flora with little difference in genus quantity.

Key words: Dongping Lake; intestinal flora; quantity of intestinal flora; species of intestinal flora
