Yes, while treble hook is allowed in Area 29 (barbless for salmon, barbed hook allowed for other species), only single barbless hooks can be used for ALL species in the Tidal Fraser River.
I was just having a discussion with one of the communication staff at the department and brought up what is published at:
http://www.pac.dfo-mpo.gc.ca/recfish/Tidal/area29_e.htm#Fraser%20River-Pitt%20River%20Tidal%20WatersIt is prohibited to use more than one line when sport fishing in the tidal waters of the Fraser River. While only one line per angler may be used, gear designed to catch a maximum of two fish at one time (bar rig) is permitted in this area, provided that two single barbless hooks are being used.
This paragraph can be interpreted that only single barbless hooks are needed when using a bar rig while treble barbless hooks are allowed when fishing with an artificial lure such as spoon or buzz bomb. Now that the problem has been identified, it'll be looked at and the wordings will most likely be changed soon.
When poaching of white sturgeon happens, phone them in and record the license plate of the vehicle. Sturgeon poaching is not taken lightly by the enforcement officers and they will respond as long as enough information is given to them for follow-up.
1-877-952-7277 (RAPP) is the number to phone.
