Dear Editorial Board Member, 

We are working on marine alien plankton, and we were wandering if any marine alien bacteria listed in the EASIN Catalogue could be treated as planktonic organisms (i.e. bacterioplankton). The list of species is: Aerococcus viridans, Photobacterium damsela, Vibrio cholerae. Based on some search in the internet, we did not find any indication that these species are related with the bacterioplankton, with the exception perhaps of Vibrio cholerae. Could you please confirm this?  

Thank you.

Aerococcus Viridans is a rare pathogen, environment-mostly dust and air:: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5324413/-do not include 
P. damselae is considered an obligate pathogen (infests fish it seems via copepods). Me too, I could not find this bacteria to be classified as a plankton( the reason could be that it is obligate patoghen and could not survive in the aquatic environment for long)

Vibrio cholerae- this species includes pathogen and non pathogen strains; aquatic and human body environment
V. cholerae is a pathogen, a microbe that increases with raising sea temperature (https://www.newscientist.com/article/2100371-warming-seas-linked-to-rise-in-cholera-bacteria-in-europe-and-us/)
Distribution in Europe> https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4534830/

The bacterial component of aquatic pelagic ecosystems is bacterioplankton. So they could be classified as bacterioplankton or marine bacteria.
In our case probably is better to be included in the EASIN date base as bacterioplankton (marine and freshwater)
