When it comes to fish, I know it means"in your possession" where ever you are. As there is no mention of exceptions I believe it means anywhere.
Of course if you look at the definitions on page 96:
possession quota … the number of fish of any
species that an angler may have in his/her
possession at any given time, EXCEPT at
place of ordinary residence (see above).
In most instances, the possession quota is
two times the daily quota.
I would expect that this definition would also apply to roe (yes, even if it only talks about fish, the spirit of the law is to define possession at any time, EXCEPT at the place of ordinary residence). So, Everyday, the roe shouldn't be a problem. And, page 9 :
Fin fish… the use of fin fish (dead or
alive) or parts of fin fish
other than roe
is prohibited throughout the province,
So, using roe from one source to fish isn't illegal either.
As to the whole invasive species thing, it only talks about live fish species with respect to moving or possessing. And, if you're really worried about invasive species, then you need to ask yourself, how many times do you wash your waders and boots as per the suggestions on page 88 of the synopsis? You could be transporting some strange aquatic hitchhikers.
Trout roe will be pretty small though, IMO but should still work. You might seriously consider tying it into roe sacks instead though, after curing.
