I've heard this phrase used but don't really understand what it means.  Can someone fill me in please?

The bulk of the fish hold in a small percentage of the water....

Thanks.  I was thinking that it might mean that the fish relate mostly to visible cover like they would in a small body of water as opposed to having to try to find them miles off shore.

I suppose it depends on the context of the statement. That makes sense to me to an extent, but even the small bodies of water I fish I've found fish without visible cover. 

 

Someone else will weigh in
