Reply to comment by AUniquePerspective in What are the effects of adding rock salt to a cooler full of ice? by Ok_Kareem_7223

Yes, my last paragraph said that adding salt is clearly better. Reread the OP's question, they aren't asking what's better in practice. They want to know what lasts longer.

If we assume a perfectly insulating cooler, both methods last forever and it's a tie.

They want to know if they have reason to believe fishers. They're missing the point. This isn't a question of total heat within the cooler/ice/water/fish system. The goal is to prevent rotten fish. The fish is the only part of the system the fisher cares about.

How can you assume a perfectly insulated cooler? No one ever said anything about that. The answer should be about things that really exist.

That's not quite correct. AUniquePerspective, who EmeraldHawk is responding to, introduced that above.
