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.

基于土地利用和农场组成部分的蜗牛农场系统评估

在这项研究中，分析了希腊蜗牛农场的结构和管理特征，以实现可持续的粮食生产最大化。调查了诸如耕作系统分类和评估各种年度生产参数的影响等目标。（2017年）通过问卷调查收集了数据，并在分布于六个不同地区（色雷斯，中马其顿，西马其顿，色萨利，希腊西部和阿提卡群岛）的29个蜗牛农场进行了采样。计算连续变量的描述统计量和分类变量的频率。使用非度量多维标度（nMDS）分析了场之间的相似性。农场的平均经营时间超过八个月，平均年产量为1597公斤新鲜的活蜗牛。结果记录了五种耕作系统：高架部分（7％），净覆盖温室（38％），具有净覆盖温室的混合系统（10％），开放田地（38％）和具有开放田地的混合系统（7％）。蜗牛农场的底物类型，可用设施和设备有所不同（大多数开放式农场之间的相似度为60％）。农场定居点的地理位置不仅影响生产力，而且还影响运营时间，尤其是在开放式农场中，这是由于其在多种气候类型下的运行。和设备（大多数开放式农场之间的相似度为60％）。农场定居点的地理位置不仅影响生产力，而且还影响运营时间，尤其是在开放式农场中，这是由于其在多种气候类型下的运行。和设备（大多数开放式农场之间的相似度为60％）。农场定居点的地理位置不仅影响生产力，而且还影响运营时间，尤其是在开放式农场中，这是由于其在各种气候类型下的运行。
