I wouldn't take my chances for more than 48 hours uncooked.
However... put it on a plate with some lemon juice and herbs/spices and cover with waxed paper and microwave it for a few minutes. However you season it, you can microwave it and I promise it is fabulous and fast. You can then put it into the fridge for a few more days. I will be eating trout that I cooked over 5 days ago for lunch tommorow! I should be okay!!!
Hope you feel better.
also, I would cook it for now.
Fish!! I ordered Sea Bass last night at a restaurant and I hated to do this, but I sent it back. I could smell the rancidity when the server put it down in front of me and I tested a piece just to be sure. It definitely had the wrong taste and smell. I got a good piece of salmon instead. I do not think it was properly refrigerated although it had not been frozen.
Like the other poster mentioned, I think 48 hours is safe. You're going to pick up off odors soon but you should be safe food bacteria wise within that time frame.
The side effects of allergy medications keep some people from using them. Natural remedies can be a great alternative, but some are more effective than others.
