Muskie Stripping and Records at Spirit Lake IA Fish Hatchery
I remember once ice fishing and as we got all the tip ups set up a flag went up and we iced a pike. A few hours went by and we didn't get another flag so we pull the tip ups up, then pulling the tip up in which my buddy caught the pike and he says does anybody want this fish? and as he was saying it he kicks this pike into the hole, I said yes, and quickly tried to grab it and that pike took off like a freshly caught fish. I couldn't believe it.
Also remembering talking to a resort owner as he had a client come in with a 36 inch muskie in the bottom of his boat, pretty beat up and out of water for some time. He convinces the client to release the fish after tagging it. It ended up getting caught many years later at 43 inches and even went over/through a dam.
I think a lot has to do with two things about the video. 1) the water temps are cooler than they are in the summer period which yields more dissolved oxygen and 2) (this is the main one) the fish just got knocked out and didn't have to fight a line to be released. Think about that - could you hold your breath longer if you were rested or after you ran a 100 yd dash?
