For Alaska it gets a little tricky. Not only location, but time of year is a variable as well. King Salmon for example:
Nonresident- The nonresident bag and possession limit is one king salmon, 28 inches or greater in length;
- From January 1 through June 30, the nonresident annual harvest limit is three king salmon, 28 inches or greater in length;
- From July 1 through July 15, the nonresident annual harvest limit is two king salmon, 28 inches or greater in length; any king salmon harvested from January 1 through June 30 will apply towards the two fish annual harvest limit;
- From July 16 through December 31, the nonresident annual harvest limit is one king salmon, 28 inches or greater in length; any king salmon harvested from January 1 through July 15 will apply towards the one fish annual harvest limit;
- Immediately upon landing and retaining a king salmon a nonresident must enter the species, date and location on their sport fishing license or on a nontransferable harvest record;
I've been in June and we each took home 50lbs. of fish; King Salmon, Halibut, Rockfish (Sea Bass) & Ling Cod. We could keep 3 Kings.
I've been in August and we each took home 100 lbs. each. We could only keep 1 King, but the Silvers were running and you could keep 5 per day.
