Luminous and agar-digesting bacteria occurred seasonally on fish. Luminous strains occurred mainly in the gut contents. A group of sea-water-loving Pseudomonas spp. which seem to require sea water for growth on initial isolation was present on the flatfish in variable numbers throughout the year. A more or less distinct intestinal flora was present in North Sea flatfish in which a homogeneous group of micro-organisms provisionally labelled Gut Group vibrios predominates; this group includes luminous bacteria. The bacterial populations of skin and gills were similar in both the fish studied and were composed principally of Gram-negative rods of the Pseudomonas and Achromobacter genera. The composition of the bacterial flora of the two flatfish, as calculated from an analysis of strains isolated from sea-water agar plates, was: Lemon sole: Pseudomonas 60%, Achromobacter 14%, Alcaligenes 8%, Flavobacterium 5%, corynebacteria 1%, cocci 1%, Gut Group vibrios 9%, miscellaneous 2%. Skate: Pseudomonas 53%, Achromobacter 13%, Alcaligenes 6%, Flavobacterium 9%, corynebacteria 2%, cocci 3%, Gut Group vibrios 12%, miscellaneous 2%., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-16-1-205
