Looks like the weekend for the tournament has been chosen as a backup Halibut fishing weekend if the annual spring Halibut catch doesn't yield the quota by then.

Spring Season:
Open dates are May 13-15, May 20-22, and June 3-5.
Backup days (if sufficient quota remains) are June 17-19, July 1-3, July 15-17 and July 29-31.
The catch limit is 105,948 lbs.

Summer Season:
Open every other Friday and Saturday (Aug. 6-7, Aug. 20-21, Sept. 3-4, Sept. 17-18, Oct. 1-2, Oct. 15-16, Oct. 29-30)
until the total subarea all-depth catch limit of 141,265 lbs. is taken.
