As I mentioned previously in another thread, there are some major concerns about large mouth bass as they have been found in systems where they shouldn't be such as Nicomen slough and the lower Vedder where the Sumas connects as people have encountered large mouth bass there.
The CO I talked to I believe his name was Scott, he basically said that next year (This year) that the limit will be changed to either unlimited or a very high number. Not sure about the regulations about not releasing them once caught but his words basically were catch, kill and dispose of them in any manner.
when catching salmon smolts in the kanaka or alouette river they constantly get small and largemouth bass. they also get chinook smolts from the harrison and i think that's kinda cool.

Largemouth bass presence was confirmed for 50 waterbodies in the lower Fraser
River watershed, including 16 lakes and 34 streams (see Table 41). Based on
provincial watershed coding, these records are distributed across 20 drainages.
Though not all waterbodies containing largemouth bass may possess
downstream connectivity due to physical or hydrologic isolation, 15 of 20
drainages are potentially linked by shared receiving waters of the Fraser River
while the remaining 5 drainages are potentially linked only by marine or estuarine
waters.
The first recorded occurrence of largemouth bass in the Lower Mainland Region
was in 1987 in Judson Lake (Anonymous, West Coast Bass Anglers, pers.
comm., cited in Hatfield and Pollard 2006). The most recent occurrences for this
species were in 2004 when 14 records were confirmed over seven separate
drainages (Anonymous, MOE Region, pers. comm.; Chad Keogh, West Coat
Bass Anglers, pers. comm.; Maurice Coultier-Boisvert, DFO Area, pers. comm.;
Anonymous, fisheries consultant, pers. comm.; Jim Taylor, Stave Valley
Salmonid Enhancement Society, pers. comm.; Pearson 1998, all cited in Hatfield
and Pollard 2006). Provincial records contain no accounts of authorized
largemouth bass stocking in the Lower Mainland Region. That confirmed records
for this species are distributed across 20 separate drainages suggests many
populations originated through independent, unauthorized introductions followed
by localized dispersal. McPhail (2007) states that largemouth bass dispersal into
Lower Mainland Region occurred via the trans-boundary Sumas River system
while local advocates for promotion and conservation of bass angling
opportunities have advised government biologists of their belief that largemouth
bass are naturally recruiting into waterbodies in the lower Fraser River watershed
from long-established upstream sources on the Fraser River floodplain
(Anonymous, West Coast Bass Anglers, pers. comm., cited in Hatfield and
Pollard 2006). '
