I'm sure this has been discussed before, but I couldnt find it in a search.
Whats the survival rate of halibut that are "traded up" - by that I mean having a still living halibut in a live well, catching a bigger one, keeping that one and sending the original one back to the depths.
The reason I ask is that I have a large fish hold (for a recreational 26 foot boat) in the belly of the new boat, its 5'-3" long, 26" wide and 20" deep. I can flood it via a big ball valve and pump more water into it or drain it as I want. Its kinda cool.
I'd like to "trade up" halibut if I can, but not if I'll kill the guys I'm sending back down.
