Treble hook vs. barbless

From the same study:

(Taylor et al., 2001). Gjernes et al. (1993) reported that treble hooks were less likely to hook ‘‘critical’’ locations for Chinook and coho salmon, but there was no difference in mortalities, possibly because treble hooks took longer to remove.
 
Are you still allowed to use treble barbless when fishing for salmon with bait in area 25? I see this tread ended in 2018 and was just checking to make sure the regs haven’t changed.
 
Judging by the amount of fish hooked this season using single and treble hooks.... the singles looked like they did more damage to me tho I'm not a scientologist.... but when I see the single going thru eyes etc and the trebles staying in the mouth... I'd rather have a sore mouth then lose an eye
