“…Farmers use soil with growing plants, mostly as a substrate. As described in previous studies [1,40], snails fed only with green vegetables had slower growth and, at the end of the experiment, weighed eleven times lower than the ones fed with the compound ailment.…”

In this study, the structural and management characteristics of snail farms in Greece were analyzed to maximize sustainable food production. Objectives, such as the classification of farming systems and assessing the effects of various annual production parameters, were investigated. Data were collected (2017) via a questionnaire, and sampling was conducted in 29 snail farms dispersed in six different regions (Thrace, Central Macedonia, West Macedonia, Thessaly, Western Greece, and the Attica Islands). Descriptive statistics for continuous variables and frequencies for categorical variables were calculated. The similarity between farms was analyzed using nonmetric multidimensional scaling (nMDS). The average farm operation duration exceeded eight months and the mean annual production was 1597 kg of fresh, live snails. Results recorded five farming systems: elevated sections (7%), net-covered greenhouse (38%), a mixed system with a net-covered greenhouse (10%), open field (38%), and mixed system with an open field (7%). Snail farms differ in the type of substrate, available facilities, and equipment (60% similarity between most of the open field farms). The geographical location of a farms’ settlement affects productivity but also influences the duration of operation, especially in open field farms, due to their operation under a wide assortment of climatic types.

“…In the case of B. aspersae, the presence of large sporocysts and numerous metacercariae in heavily infected snails could have important consequences for their survival, especially under intensive breeding conditions, where overcrowding, and probably reproductive stress, can have additional deleterious effects for gastropods (Daguzan and Verly, 1989;Blanc and Attia, 1992;Jess y Marks, 1995;Dupont-Nivet et al, 2000;García et al, 2006). Although the association between the presence of brachylaimid metacercariae and host mortality is not clear, there is no doubt that these larval stages, which feed on the renal epithelium, cause necrotic changes in this organ (this study ;Foster, 1958;Lewis, 1969;Rashed et al, 1995).…”

“…Helix aspersa ) is the most often used terrestrial gastropod in environmental monitoring and assessment. This species has a well known biology and physiology [ 11 ] and is easily reared under both field and laboratory conditions [ 11 , 12 ]. It acquires Cd directly from soils [ 13 ], while showing a dose-dependent growth inhibition [ 13 ], and importantly, is able to access the nonlabile soil Cd pool [ 14 ].…”

Impact of Soil Cadmium on Land Snails: A Two-Stage Exposure Approach under Semi-Field Conditions Using Bioaccumulative and Conchological End-Points of Exposure

Land snails are highly tolerant to cadmium exposure and are able to accumulate soil cadmium independently of food ingestion. However, little information exists on the kinetics of cadmium retention in terrestrial gastropods exposed to an increase in the soil cadmium content, over time. There is also little knowledge about how exposure to cadmium-polluted soils influences shell growth and architecture. In this context, we examined cadmium accumulation in the hepatopancreas and shell of juvenile Cantareus aspersus exposed to elevating high levels of cadmium in soil. Also, the toxicity of cadmium to snails was assessed using a range of conchological endpoints, including shell height, width, volume, allometry and integrity. Test snails, aged three months, were reared under semi-field conditions, fed an uncontaminated diet and exposed first, for a period of 30 days, to a series of soil cadmium concentrations, and then, for a second period of 30 days, to soils with higher cadmium content. Cadmium showed a dose-dependent accumulation in both the hepatopancreas and shell. The kinetics of cadmium retention in the hepatopancreas of snails previously exposed to cadmium-spiked soils was significantly influenced by a new exposure event. The shell was not a relevant bioaccumulator for soil cadmium. Under the present experimental conditions, only high cadmium exposure significantly affected either the shell growth or snail survival. There was no consistent effect on shell allometry, but the shell integrity, especially in rapidly growing parts, appeared to be affected by high cadmium exposure. Our results attest to the value of hepatopancreas for describing cadmium retention in land snails and to the difficulty of using conchological parameters in field surveys for estimating the environmental hazard of soil cadmium.
