Wow no pointers yet, here's a few:
#1 - cast straight out, guys who cast up stream often land on top of guys who are at the end of there drift and cause tangles. I personally think the farther the better.
#2 - this escapes some people at first but DONT let your reel free spool, make your cast, close the spool down, and real in once your gear has swung down to 10 oclock.
#3 - call it out when you get a fish, some guys don't and then a real mess ensues
#4 - once that fish is hooked dont play it out far, get it in out of the travel lane quickly (once again to avoid tangles) and the play it closer to shore
#5 - befroe you drag a fish up on the beach, make sure you will retain it...I hate guys pulling pinks up on the beach and saying "s*** its not a sockeye" and then booting it back in.
#6 - and I bet many guys here don't think of this...ICE YOUR CATCH ASAP! The fraser is about 19C right now, air temp is 20-30C...fish will spoil in no time at all. I have had my fish sitting out exposed waiting for a buddy to get his limit and I cooked my fish

They look fine on the outside but you get home and fillet them and the flesh has turned soft and mushy or the layers of muscle start separating...its not a pretty sight. I posted a link to a PDF about maintaining maximum food value of a fish an temperature control was the biggest factor - I would advise all fishers to look it up, its a good read.
