During the period from June, 1988 to October, 1989, a total of 257 seawater fish, containing 247 sardines and 10 horse mackerels, obtained at four fish shops in Kanagawa prefecture were examined for the presence of motile Aeromons. It was found that 73 (29.6%) of 247 sardines and 2 (20.0%) of 10 horse mackerels were harbouring some motile Aeromonas. The attempts to identify the isolates were made by the method of Popoff and revealed that 11 (10.0%) of 110 isolates (from both sardine and horse mackerels) were identified as Aeromonas hydrophila, 25 (22.7%) as A. sobria, 22 (20.0%) as A. caviae and the rest 52 (47.3%) were untypable. The phage-typing method developed by Fukuyama et al. reveraled that 43 (39.1%) of 110 isolates were typed as one of 16 phage types. Of them, five single phage types I, IV, V, IX and XI and one mixed group containing phage type I were typed.
