Gram negative cells, 2.5-3.0 x 1.0 μm, motile by a single polar flagellum. Not
swarming on complex media. No luminiscence.
swarming on complex media. No luminiscence.
Can grow in nutrient broth with: 1% NaCl & 6% NaCl. No growth in 0% NaCl, 8% NaCl,
10% NaCl and 12% NaCl. Growth temperature 30 ºC, no growth at 4 ºC or 35 ºC.
Grows slowly, forming visible colonies on trypticase soy agar after 4-6 days; growth is
enhanced by the adition of NaCl (is a halophilic species).

Isolated from fish. Sensible to O/129 vibriostatic agent (10 and 150 µg).
Fish pathogen isolated from diseased salmonid fish, from ayu (Plecoglassus altivelis) and rockfish fingerlings (Sebastes schlegeli)
