Heliciculture is the process of farming or raising edible land snails for human consumption. Snail farms may be outdoors; in buildings with a controlled climate; or in closed systems such as plastic tunnel houses or "greenhouses." In addition, snails may breed and hatch inside in a controlled environment and later be placed in outside pens to mature.
