I just read that moving a fish back and forth is bad and could potentially kill it. What is the new/best way to revive a lethargic fish? Any way to rig a tow system (on a lake) and troll the fish forward if it isn't moving it's gill plates or would that be bad as well?

I have put them in my livewell and put their mouth up to the water intake to shoot fresh highly O2 water through their gills. It seemed to work pretty well I thought. No idea what happened to the fish after it was released, but it did swim off well.

Moving them back and forth very slowly is beneficial to the fish but when thinking in terms of a human comparison think of how hard it is to breath when the wind is blowing very hard and you are unable to take deep breaths

The speaker at the Cabin Fever Challenge in Kentucky in 2012 was very adamant that moving a fish back and forth is very harmful to them because the structure of the gills and the small flap that goes over the rear opening of the gill cover. He had done a lot of research on it. A small tear in that flap will be a death sentence to that fish. He suggested rolling them back and forth slowly is the best procedure if they don't take off right away.

Something suggested to me by a DNR fisheries tech was to hold the fish horizontal, head pointed forward and run the trolling motor. He said the biologists he worked with discouraged moving the fish backwards. The tech had handled thousands of muskies over the years in studies.

Right after he told me that, I had a fish bonk it's head on the side of the boat while in the net. It was not moving and I did what he suggested, with my son running the trolling motor at a pretty fair clip and me holding the fish. Within 40 yards or so the fish revived and took off strongly. I have done this ever since if the fish seemed to need reviving.

Gills are unidirectional, fish don't swim backwards so there wouldn't a need for them to function as such. Yes, you can suffocate a fish by pulling it backwards. After a fight fish more commonly die from acidosis caused by lactic acid build up. Oxygen is required to recover from this condition. Also, the gills are designed to function in one direction and pulling the fish backwards can cause physical damage to the gills.

I understand this is off topic but with as many times each fish in Lake Webster has been caught I think its safe to say that most peoples comments about fish mortality is way off. These fish aren't as fragile as everyone thinks.

I think most people that catch muskies have unfortunately seen otherwise when they are unable to release a fish.

Even if you don't believe they are fragile, why would you not encourage a gently release?

great thread.
pulling fish backwards drowns them.
pulling them along boatside with bogas,mouth open drowns them.

Boga Grips are a GREAT and SAFE tool for Muskie Anglers.

hold em by the tail upright and dont move em. Let them gain their balance themselves. Gills use a countercurrent exchange, blood flows in the opposite direction as 02 rich water, this way concentration gradient never reaches equilibrium and o2 will diffuse into the gill. Pulling the fish backwards takes the mechanism out. More than likely it would not kill it unless you really exhausted the fish in my opinion, but it will revive alot quicker just holding it. Pulling the fist through the water forward too quickly the 02 does not have time to diffuse as much as when the fish is regulating it itself.

I just hold the fish in the water and let it gain its senses back. When it feels strong and ready to pull away I let it go. I would never use a boga grip. If I were afraid to hold a fish with my hands then why would I fish for it. Boga grip can cause way more damage than a hand can especially if the flop and your hands slip off. A firm grip in the gill slot and a supporting second hand is all that is needed to hold these fish. Muskies traditionally don't flop around like pike do but I am sure it happens.

A bad grip up inside the gills too far can kill a muskie as well. If you like to use a Boga, make sure the one you have has the pivoting head, do not try to support the fish's weight with it, make sure you support the fish with your other hand, and it's fine. Use any tool incorrectly and it's on YOU, not the tool.

current is not supposed to enter from the back of the fish,so moving the fish backward is bad and totally useless,it's old and should be avoided.all the anglers in the fishing program in the 80's were doing it,maybe that's the reason why some guys still doing it by these days.
