Location: WI | Caught this fish last weekend, it also had a small crankbait stuck under it's head that I cut out. Thought maybe I tore the gill out somehow, but it wasn't bleeding at all in the net so it must have been a pre-existing injury. Was going to try and push it back under the gill cover, but thought it best to leave it alone and get her back since the water temps were pretty warm.

| I have seen this before in an obviously first time caught fish.It seemed perfectly healthy. |

You mean second time |

| several years back I caught an upper 30" fish and on the hookset I ripped the gill in half. Blood everywhere. A few years later I caught the same fish in the same location with the healed gill hanging out. Except this time it was 48. Never saw the fish again after though. |

Location: Mauston, Wisconsin | The blood flow through the gills is a series circuit - back to front. That way the blood picks up more oxygen. She's surviving on the right side gill- its just like you losing one lung, life may be a struggle, but it still goes on! If you cut one gill on each side they are toast.
Have fun!

| If that series circuit stuff were correct, all the gills on one side would be dead. That's not the case. You can definitely have one dead gill while the others continue to stay red/pump blood. |

Location: oswego, il | I have caught a few muskie and quite a few pike will a gill hanging out. They were light pink and had not been in place for some time. I cant say how something like this affects the long term survival of the fish but it does appear they can live on with this injury.

Location: Mauston, Wisconsin | They might remain red, but the circuit has been disconnected. Next time you catch a walleye or other food fish, cut one gill on each side & see if the fish lives. Most fish also taste better if you bleed them.
I'll dig out the research paper for you, if you want to read it.
Have fun!

| I don't believe the cut gill thing on each side either. I have caught many different species of fish over the years with pre-existing gill injuries like seen in the pic. those fish seemed fine and were back feeding again. I think it would take more than 1 gill injured on each side to kill them. Maybe a cold water injury given time to heal would help them survive better that having that injury occur with say 80 degree water temps--No proof--just a thought. |

| No ,I mean obviously first time caught on remote waters.We thought it was very odd and looked for any sign of anything and saw nothing.The fish was perfectly clean except for a detached gill.I'm just telling you what I believe to be true. |

Location: Mauston, Wisconsin | And, I'm just telling you what I believe to be true, I too have seen fish with one gill damaged on one side - never both. When I bleed a fish for food - I usually only cut one side, i.e. they don't die right away, so they bleed out better. If you cut both sides they die almost instantly, respiration ceases and blood flow to their brain likewise ceases, resulting in oxygen starvation to their brain and no heartbeat. Here comes PETA!

Location: Mauston, Wisconsin | Actually after looking at the video again, I was wrong, its not a simple series circuit -stop the video at ~ 022:4:50. Its really two parallel systems tied to a common point, and if we assume the vein's and the artery's at the rear are also tied common like they are at the front. It really gets pretty interesting, either way it does show that a single gill arch could be torn loose & the rest could still function normally on that side - my apologies for the misinformation. Remarkable adaptation for survivability.
Have fun! |
