In my opinion most fishers are not greedy and will not take unlimited fish. Consider Joe who would like about a dozen sockeye from this bountiful run, 3 fresh for the barby over a couple of weeks of fishing, 4 to give to friends and 5 for the freezer. At two a day this will take perhaps 7 days on the bars, allowing for one day when the fishing gods don't smile on Joe.
Once Joe has committed to the day and driven two hours from Richmond and caught his two fish, why hey make a day of it. Try for a Chinook and do a little catch and release on the sockeye with the result he is on the bar most of the day.
If the limit were 4 a day, Joe might stay home after four days fishing and do some chores around the house. After all he has caught quite a few and he isn't greedy.
Out of the multitude of licensed fishers between White Rock and Hope, there are perhaps 5000 like Joe who can fish the days they want. If this example is correct, that would be 15000 extra man days on the bars due to the two fish limit.
I wonder why we have the two fish limit when these sockeye are fished with gill nets and purse seines all the way from Port Hardy? In 2010 they had seine boats up in Kamloops Lake and a four fish limit in the Thompson when the fish are much deteriorated compared to the Fraser Valley.
So what is your opinion, does the two fish limit lead to crowding of the fishing bars?
