An Assessment of Snail-Farm Systems Based on Land Use and Farm Components

Simple Summary This study's goal was a thorough analysis and a detailed characterization of commercial snail farms in Greece, considering the unstructured development of the snail-farming sector over recent years. Additionally, the characterization of snail farms in Greece could help Southern European countries improve heliciculture. This study classifies 29 farms in five snail 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%). Results showed the impact of various parameters (farming system, region, equipment, and facilities) on annual production. Snail farms were dispersed in six different regions (Thrace, Central Macedonia, West Macedonia, Thessaly, Western Greece, and the Attica Islands). The location affected productivity, but also influenced the duration of operation during an annual cycle. 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.

Automated summary

This study conducted a thorough analysis of commercial snail farms in Greece, examining the impact of various parameters on annual production. The geographical location of farms significantly influenced productivity and operational duration, especially for open field farms.
