 by a non-target species so for example let's say you're fishing for speckled trout and you hook a special speckled trout and you're reeling it in and then all of a sudden the line goes slack and by the time you get the line all the way to the boat you realize that something has bitten your speckled trout in half that is what depredation is wow okay does it happen actually instead of being bitten half do a lot of people kind of reel in a shark at that point
