I'd be more worried about the shrimp dying from too much oxygen. The water either wouldn't be able to hold all the gas and it would just not dissolve into the air or it would dissolve to unsafe levels for the shrimp.
Too much oxygen? LOL. No. You'll never over saturate your water with oxygen to the point of killing livestock.
