What temperature is considered "the low end" for shrimp?

I read that at lower temperatures, the shrimp breed less, but live longer and grow bigger.  That's pretty much what I want.

Good question.... I've heard of shrimp being shipped in freezing cold weather. Not cold enough for the water to freeze, but cold enough for the shrimp to basically freeze but not die.... and after warming back up, resumed normal activities.

So...... I guess 50-60's might be low end?

I have heard of people keeping shrimp in mid to high end 60's without concern.
