Decapsulated brine shrimp cysts cannot hatch. Some Aquabuy customers report very low hatch rates – this is due to two things. Either un-decapsulated eggs working their way into the decapsulated stock during the decapsulating process or decapsulating not removing 100% shell. In our in-house tests we have measured a hatch rate of under 0.5%. Decapsulated eggs are intended as a straight up fish food.
