“…Compelling evidence points to the survival of mature specimens during winter acting as a crucial factor in the population dynamics of both wild gastropod populations [ 15 , 32 , 49 , 50 ] and farm-reared snails [ 4 , 12 , 13 , 43 ]. Application of the “sandwich” system yielded a significant improvement in overwinter survival compared to the sole use of LFC.…”

“…However, this method could be ineffective during the colder winters specific to the humid continental climate of Central Eastern Europe, potentially leading to increased mortalities among overwintering snails. In fact, death rates of mature C. aspersum snails during the winter of 2005/2006 have exceeded 70% in most snail farms from Romania using the standard ISISF system [ 4 , 12 ]. This was a critical issue given the central role of breeding herd survival in successful snail farming [ 8 , 13 ].…”

(1) Background: Hibernation in pens covered with LFC was associated with high mortality of C. aspersum 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. Protective structures based on straw, LFC, and/or HDPE were tested at pilot level (no snails). The most suitable system was applied under farm conditions. (3) Results: Wood and ridge-tile micro shelters were significantly preferred to corrugated iron micro shelters. Burrowing specimens acted as shallow-burrowers, and this behaviorwas significantly more common for looser soils. All pilot systems displayed significantly higher thermal protection efficiency compared to the sole use of LFC. The balance between straw moistening and thermal protection favored using structure soil/LFC/straw/10-cm air cushion/HDPE. Its use yielded significantly higher survival compared to the sole use of LFC. Most hibernating snails clustered together in large groups, attached on the lower surface of micro shelters. Predator occurrence appeared to marginally affect overwintering survival. (4) Conclusions: The “sandwich” system could be an effective solution for overwintering mature C. aspersum snails in colder climates.

“…Hence, high mortality was observed between November and May. Many studies revealed that animals has lower ability to tolerate stress during their first stages of life (Zippay & Hofmann 2010;Gheoca 2013;Diederich & Pechenik 2013).…”

The study was aimed to examine a snail organic culture system and describe the cultivation properties of Cornu aspersum. The environmental parameters of the culture system and their effects on the growth and mortality rates of C. aspersum were determined between November 2014-October 2015. Snails were fed Spinacia sp. (spinach), Urtica sp. (nettles), Brassica oleracea sp (cabbage) and formulated diet. The feeding and growth rates increased with increasing temperature. Shell height growth rate was the highest in spring while the live weight growth rate was the highest in summer. Mortality rate of the baby snail was higher between November 2014 and May 2015 due to stress conditions such as handling and varying temperatures during their first stages of life. High mortality observed in adults could be associated with the spawning activity of the matured snails that caused physiological exhaustion. The result showed that the best culture cycle for C. aspersum was from spring to autumn in Black Sea region and in order to prevent postreproductive mortality, snails reached to marketable size should be harvested.

“…To cite an example, Yildirim et al [10] noticed a decline in the population of two edible snail species, namely Helix pomatia and Cryptomphalus aspersa, due to over-harvesting and increasing use of agro-chemicals. In his response to problems of a similar nature, Gheoca [11] suggested heliciculture as a tool to maintain the edible snails' natural population in Romania. However, harvesting of edible snails from the wild environment, mostly during the rainy season, is common in many parts of the world, including several areas of India, where nourishment is poor or scarce and where the establishment of snaileries for farming mini-livestock could be of benefit to the population (Figure 1).…”

In the present paper, we describe the farming system of Pomacea canaliculata, an edible freshwater snail, as it is practiced by a farmer as mini-livestock in the vicinity of Andong in Korea. We visited the snail farm several times in the summer and winter of the year and conducted interviews with the farm manager using a semi-structured questionnaire. The farm is housed in polythene tunnels and uses a tank pen of trench type made up of propylene and measuring 1 m × 2 m × 0.5 m (length × width × height) in size. A regulated inflow of fresh water and outflow of used water was installed, with water level not exceeding 5 to 7 cm. As feed of snails, commercial fish feed is generally provided. The life cycle of the P. canaliculata might differ in captivity under the controlled environmental conditions than that of an individual in the wild environment. The farming system of snails, particularly P. canaliculata, does not involve high labor-intensive, high capital investment and also does not require high through-put cutting edge technology. In addition to providing nutrient-dense snail meat, establishing a snailery could therefore augment the economic condition of farmers in the poorer regions of the world and encourage sustainability and biodiversity conservation.
