Let's take a hard look into the justification of a one fish vs, two, limit.
It makes absolutly no difference if the limit is 1 or 4. The same exact amount of fish are gonna get taken out of the river everyday no matter what the limit, with the exception of a few prime water condition days.
Here's an exaple.
We are fishing the Willamette river at Oregon city with 50 of our closeset friends. A good bite starts in the garbage hole. We see 50 fish get taken out and then it dies. Later in the day another little push of fish moves through and 15 more get taken. How did the one fish limit help this situation? It didin't. The presure these fish recieve daily is beyond what they can handle. If one boat catches a limit of 1 fish a piece, the next guy moves in to get his share. It's not like the river becomes void of people once they catch their limit.
EVERY FISH IN THE RIVER THAT IS GOING TO BITE IS DEAD AT THE END OF THE DAY. NO MATTER IF THE LIMIT IS 2-OR 10. THE EXACT SAME NUMBER IS GONNA BE TAKEN AT THE END OF THE DAY, PERIOD.
How many days so you see the Wilson tidewater with no boats on it, because they all limited out and now with a 1 fish limit it will save so fish. What a crock of $hit. The presure transfers to the next boat waiting to get theirs.
