I wouldn’t feel too bad about it if I were you. There are obviously others who didn’t dig into the regs enough to find the closures.
The cynical part of me thinks they want the regs to be complicated so when people fish in the no-go zones they can say fishermen can’t be trusted to follow them and they should just shut everything down to be sure. The ‘abundance of caution’ phrase was used a lot by the fisheries minister in defence of the Pender bluffs closure for six months when the whales are there for 7-10 days per year. Apparently science can’t compete with politics when it comes to fisheries management decisions.
If you just read the table under Salmon for area 29 it says Chinook are Open(See Restrictions) for 29-5. Toward the bottom of the Restrictions table is a link to the Strait of Georgia Chinook Closure map that shows the closed area in blue stripe.
There is another link near the top of the Salmon section under Maps called ‘Area 17 and Sub-areas 29-1 to 29-5 Nanaimo, Sechelt, Strait of Georgia: Chinook and Coho openings and other management measures’ that takes you to the map I posted.
