This question came up over the campfire one evening. Bird Creek signage says 3 salmon limit and 3 in possesion. I read it as this is for the day your fishing and until the 3 are consumed. The reason it came up is we actually saw this happen, what if a person was fishing friday evening and caught their limit then took the fish processed to thier vehicle then returned after midnight (saturday morning) and caught more for their saturday limit.
I have seen it done like this on the Russian but didnt really question the practice as it is 3 per day and 6 in possesion. Can someone give me the right answer so if I see these guys again I can politely let them know what they are doing is wrong if it is wrong trying to hopefully educate some people as well as myself.
