Fin rot is progressive necrotic disease of many fish species. To determine the bacteria associated with the disease in Atlantic salmon (Salmo salar), fish were randomly sampled at Latvian fish hatcheries. The degree of fin necrosis we were divide in four groups: active fin rot, healing fin, healed fin and health fin. We were made standard bacterial analyses and were found Flavobacterium spp. in 61.4% cases, Aeromonas hydrophila in 31.8% cases, Aeromonas salmonicidae 4.3% cases and Pseudomonas aeruginosa in 2.5% cases. More bacteria we were found in summer time (July, August and September), but less in April and May, on the smoltification time.
