Tightening the rod down helps. Another thing to consider is using the longer 5' downrigger clips. This lets the rod tip "shake" a little more to telegraph the shaker. Another thing is not to handle the fish. I never touch or net a fish I am releasing. I grab the hook and unhook them. The WDFW gives out dowels with a cup holder scewed in the end of it. You can slide it down the line and pull against it with the line in the other. It is easy to unhook them this way with barbless hooks. I also use a short gaff to slide down the line to release them also. i very rarely ever kill a shaker, but it does happen.
