Well, I'm torn on this.  Maybe somebody can straighten me out.  If you use a plastic bag to weigh a fish doesn't it rub against the slime coat and remove it?  Is it better to punch a whole next to the bony lip or to remove the slime coat?  Or maybe we should use plastic bags with water in them as tournament fisherman do.  Weigh the bag with the water, then weight the bag with water and fish, and subtract the weight of the bag and water to get your true weight.  Or is a plastic bag so smooth that it does little damage to the slime coat?  What do you guys think?

Tried one of those plastic bags before. Not to rain on your parade KU, a little flip and flop there rips those cheap plastic bags with their fins. You know, as when your bringing in the groceries and wham, there on the ground.

Man you have some low quality grocery bags ;D ;D ;D.  Also, most of us aren't weighing Fork fish either.  What a problem to have.

As for the slim coat thing, I just always made sure the bag was wet before weighing them.  Not sure if that helps or not, but I think it would.

I also must add that since this original post I have gotten a X-Tools scale for CHEAP on Ebay.  No more bags are poking holes for me.  

KU_Bassmaster,

It sounded like a good idea to me, but then the more I thought about it the more I had questions.  I was thinking the same as you that if I keep the bag wet it would probably be the best way to get a weight.  I just wondered if anybody else had more definitive information on the subject.

I have always just put the scale hook through the hole made by my lure hook. That way, you don't have to worry about putting two holes in the fish's mouth or ripping grocery bags.
