You know how minnows bunch up in the corner of the bag when you get them? I've noticed they do the same thing in my baitwell. I figure, when the boat is moving around alot and bouncin back and forth that the minnows get slammed up against the sides pretty often. I took some thin plastic sheet and curved it into the corners of the square well to make it so they wouldn't really have anything to slam into. Now that I think about it, they do seem to stay alive a bit longer since I did this.
Short answer for me would be a definite probably.
