Fourth line down in the table...
Areas 13 to 18 Chinook Apr 1 - Mar 31 TBD Minimum size limit is 62 cm.
As regards to the to be determined daily quota, it is presently at two as per the regulation and any change to daily limits on any other size if implemented, will be determined and implemented if warranted. The fishery notices that were on the web site with the maps attached were removed as those restrictions expire March 31st each year.
In summary the daily limit for Area 13 to 18 is two chinook with a minimum size limit of 62 cm as per the Limits and Management Measures table which starts on page 24 of the guide. In all other Areas, the minimum size limit is 45 cm as per bullet 5 in the Limits section of page 15 of the guide.
I hope this helps but please contact your local DFO office if you need further clarification.
