The "Sandwich" System: A Potential Solution for Protecting Overwintering Snails Reared in Semi-Intensive Heliciculture Farms in Colder Climates.

(1) Background: Hibernation in pens covered with LFC was associated with high mortality of snails in Romanian snail farms. This three-year study aimed to develop a simple, but effective system for protecting breeders in colder climates. (2) Methods: The first phase investigated the (pre)hibernal burrowing behavior and the overwintering habitat choice.
