双壳贝类已被许多国家作为健康食品推广。然而，关于双壳类消费者的购买行为和态度的信息很少。本研究的目的是调查的营销和质量方面的几个双壳类的经济价值，在葡萄牙，并检查每个受访者的人口和社会经济地位与双壳类消费的态度和偏好之间的关系。随机抽取的1778人回答了一份基于网络的问卷。大多数受访者声称消费蛤（小母鸡地毯蛤和日本地毯蛤），通常更喜欢国产双壳贝类。在选择活双壳类时，最重要的标准是透明度、大小和壳的清洁。大多数消费者在超市购买蛤蜊，并对与其消费相关的风险有很好的了解。对销售机构和产品标签信息的信任是购买双壳贝类的主要感知质量标准。尽管如此，消费者的态度和偏好因其人口和社会经济特点而有很大差异。目前的调查结果提供了一个有用的工具，生产商和利益相关者参与贸易链的双壳类了解消费概况和最重要的质量标准，在双壳类购买。此外，这也是国家主管当局预测双壳贝类消费风险以及了解捕捞区发生污染的不同情况的一个重要工具。(C)2014爱思唯尔有限公司版权所有。
Bivalves have been promoted as healthy food in many countries. Yet, little information is available about bivalve consumers' purchasing behaviour and attitudes. The aim of this study was to investigate the marketing and quality aspects of several bivalve species with economical value in Portugal and to examine the relationship between each respondent's demographic and socio-economic status with bivalve consumption attitudes and preferences. A randomly selected sample of 1778 people answered a web-based questionnaire. The majority of respondents claimed to consume clams (pullet carpet shell clam and Japanese carpet shell clam) and usually prefer bivalves from national production. Smell, size and cleaned shells were considered as the most important criteria when choosing live bivalves. Most consumers buy clams in supermarkets and revealed good knowledge about the risks associated with its consumption. Trust in the selling establishment and product's label information was the main perceived quality criteria associated to bivalve purchasing. Nonetheless, consumers' attitudes and preferences differed considerably according to their demographic and socio-economic characteristics. The current findings provide a useful tool for producers and stakeholders involved in the trade chain of bivalves to understand the consumption profile and the most important quality criteria involved in bivalve purchase. Additionally, it is an important tool to predict the risks of bivalve consumption as well as to understand the different scenarios of contamination occurring in harvesting areas by national competent authorities.
