I have over the years tried many different ways to keep the fish I catch dip netting properly cared for while hanging off a small ledge in the canyon. I have used the 5 fish on a stringer (cut and bled) and laid each stringer in a small eddy (if one is available), or partially fill a small trash can (rough neck) with water and or a large cooler.
Each method has it's draw backs since we are limited by the dip site we are fishing but over the years it seems the best method is still the stringer in the river method. Sometimes when the fish are running three to a dip, the permit gets filled quickly and we are off the rock before we have lunch and then there are the slower times where you catch just enough fish each hour to not throw your net in the water and walk away but it takes all day. So keeping your fish fresh is more important. I cannot count the number of times I have seen folks just whack their fish on the head, throw them on the banks or in the grass crawling with flies and I shudder as the quality is less then pristine for such a delicious specimen.
So, for all the folks that are not lucky enough to have a boat to float while dipping, what is your preferred method to caring for your fish while out in the field?
