The study was carried out to determine the characteristics of snail farming in Edo South Agricultural Zone of Edo State Nigeria. The interview schedule was used to collect data from 60 snail farmers randomly selected from six cells in the study area. Information on the socioeconomic status of the farmers, production system, management practices and production constraints in the snail farms were elicited. The constraints were determined using a four-point Likert-type scale; a mean score of ≥ 2.5 was considered as a production constraint. Majority (85.0 %) of the respondents were part-time snail farmers. The major species of snails reared were Achatina achatina and Archachatina marginata, reared by 43.3 and 26.7 % of the farmers, respectively. Semi-intensive system of production was practised by 40.0 % of the farmers. Majority (78.0 %) of the respondents used car tyres to house their snails. About 56 % of the respondents kept their snails for 1-2 years before sale. Up to 51.7 % of the respondents separated their snails into different pens according to their size/age. The most commonly used feeds were vegetables (71.2 %), plant leaves (67.8 %) and kitchen waste (59.3 %). Records of snail production activities were kept by 75.0 % of respondents. The major constraints identified were lack of capital (3.31), inability to get good laying stock (3.00), lack of formulated feed to buy (2.98) and slow growth rate of snails (2.52). The potentials of snail farming in the study area have not been fully exploited as farmers produced at subsistence level.
开展该研究是为了确定尼日利亚江户州江户南部农业区蜗牛养殖的特点。采用访谈提纲从研究区域六个单元中随机抽取的60位蜗牛养殖户收集数据。了解养殖户的社会经济状况、生产系统、管理措施以及蜗牛养殖场的生产制约因素。使用四点李克特量表确定制约因素;平均得分≥2.5被视为生产制约因素。大多数(85.0%)受访者为兼职蜗牛养殖户。养殖的主要蜗牛品种是非洲大蜗牛和带边玛瑙螺,分别有43.3%和26.7%的养殖户养殖。40.0%的养殖户采用半集约化生产系统。大多数(78.0%)受访者用汽车轮胎作为蜗牛的养殖场所。约56%的受访者在出售前将蜗牛饲养1 - 2年。高达51.7%的受访者根据蜗牛的大小/年龄将它们分栏饲养。最常用的饲料是蔬菜(71.2%)、植物叶子(67.8%)和厨余(59.3%)。75.0%的受访者记录了蜗牛生产活动。确定的主要制约因素是资金短缺(3.31)、无法获得优质种螺(3.00)、缺乏可购买的配方饲料(2.98)以及蜗牛生长速度缓慢(2.52)。由于养殖户处于自给自足的生产水平,该研究区域蜗牛养殖的潜力尚未得到充分挖掘。
