Tilapia is a freshwater fish and it still has almost as much sodium as many saltwater fish. Shrimp has roughly 3 times the sodium found in tilapia. Seems too high.

And yes, all fish contains sodium. Might sound strange but if they didn't, they would dehydrate by osmosis while living in water since even most freshwater has salt in it.

We already know that snakes can handle up to around 60 mg per 3.5 oz of fish. I wouldn't push it as high as 150.
