Barotrauma video

Stole this from the MT board as a lot of us fish for crappies (Me) LOL. Really good video and well done study that I think is very useful not only for crappies but walleye and perch as well. Feel free to comment should be a good dialog.

Interesting video. I've heard of this, but never experienced it while fishing or saw any studies on it.

I didn't ice fish then, but I remember in SD, a section of Lake Francis Case (Missouri River) had a regulation that the first 4 walleye caught ice fishing had to be kept and the normal minimum length limit for walleye did not apply when ice fishing. Your daily limit of walleye was 4. 
I was always told barotrauma was the reason for that regulation.

Interesting thing, I saw this specific regulation changed at the beginning of 2023 and no longer applies, but never heard why it was changed.

Well that settled it…I’ll just have to keep every crappie I catch! Damn!

Like that was an issue.  I honestly think is a good policy. I do try to fish shallower that 20' most of the time so I don't have to worry if I choose to release one. I know on Keyhole you do see a few dead crappies under the ice from time to time. Mostly small fish which I  think struggle to get them selves deeper. I would be interested to see if a release aid tool would help like they do in the ocean. Maybe another study.

😂😂😂😂

The release tool would be a great next step, just to see…

 Interesting study , there are articles and videos on fizzing all kinds of fish

Fizzing is not a great option, lots of studies on long term mortality.  Better IMHO to stop fishing deep once you have the fish you want to eat.

Research is pretty limited for descender use on most species that are targeted through the ice. Seen a few instances of folks pushing using a descender mentioning some obscene number of fish they released that day. Irresponsible use in my opinion. Makes it hard for me to support their use until we see more studies.

 Maybe so I guess BASS has a huge stake (money) in this game they wouldn’t want to hurt their future
  As always some biologist are in favor of this and others are not ,
 http://Many anglers found this technique easier and assumed it caused less damage. However, in trials conducted by Texas Parks & Wildlife Department under controlled conditions, researchers found that survival was significantly higher among fish that were side fizzed
 🤔 just like everything pros and the cons

Interesting watch! Thanks for sharing.

I was going to share the same thing. Great stuff by Mr. Wieb once again!

I agree!!! I hope uncut angling starts putting out regular content again.
