Chumming with dry ice?

[tnguyen5791]

I don't know if this is legal or not, but can I throw dry ice under my boat to cool the temperature down a bit, hence attracting trouts with the "cool spot?" I know trouts prefer cool water, but this idea seems kind of suspicious for them. Has anyone ever tried it? I'm thinking dropping the dry ice at the bottom of my boat, then move 30ft away and cast into the dry ice spot after a while. I've never try it though.

I dont think thats going to work very well at all

Firstly, you would need a ton of dry ice to significantly cool a large volume of water.

Second, the dry ice will sink to the bottom so you will get most of the cooling - what little there is - deep rather than shallow.

Third, the dry ice will put out a ton of bubbles which will likely scare the fish away.

Fourth, the fish will need to swim right through the cool water to know its there. They cant sense it from some other part of the lake. But they wont come close because of the bubbles/noise.

Finally, dry ice is frozen carbon dioxide. As it sublimates into the water, you will be adding carbon dioxide to the water. Fish need oxygen to live, so you will be making the water essentially toxic to the fish. They wont want to stay around in water with less O2.

Plus Id be willing to bet most municipalities will frown on you putting that kind of thing in the water. It could easily be considered toxic dumping.

Beat me to the punch while I was typing.
