感官特性已被证明是一般鱼类消费的最大驱动力，也是完全接受水产养殖鱼类的主要障碍之一。本研究的主要目标是确定消费者对养殖和野生鱼类的喜好，并评估有关物种和生产方法（野生捕捞/水产养殖）的信息对它的影响。两组约300名参与者，每组每周至少食用两次鱼，具有相似的社会人口分布，在西班牙的三个地区招募。两组参与者对四种不同的鱼种（黑斑鲷、金头鲷、鲈鱼和大菱鲆）进行了评估，每种鱼种都来自野生捕捞渔业和水产养殖业。在每个种属内，同时获得样品，并冷冻至最长1个月的评价。一组个体在盲态条件下对鱼样进行评价，另一组个体在知情条件下对鱼样进行评价，两种情况下都检测到了明显的物种效应，尽管知情条件和盲态条件下观察到了相似的喜好特征。平均喜欢分数的鲈鱼，大菱鲆和金头鲷没有差异，这些物种显着更赞赏比黑点鲷。提供给消费者的信息有显着的影响，享乐评价的鱼样品。因此，在知情的情况下，参与者更喜欢野生鱼，但有趣的是，当没有向他们提供信息时，情况正好相反。值得一提的是，在知情和盲态条件下对养殖鱼类进行了类似的评估，而当向消费者提供信息时，对野生鱼类的喜爱程度显着增加。这些结果似乎表明，养殖鱼类本身并没有负面形象的消费者，但也表明存在一个普遍的积极态度，野生鱼类。消费者对养殖鱼与野生鱼的信念的显着影响，观察在知情condition.These研究结果构成了一个有价值的见解，并提供了一个乐观的情况下，养殖鱼的感官特性的改善，水产养殖部门似乎没有必要。然而，我们需要向消费者提供可靠的数据，帮助他们根据科学证据来评估这两种鱼类的价值。相关性声明养殖鱼类的感官品质无需改善。(C)2015年由Elsevier B.

Sensory characteristics have been proven to be the strongest driver of fish consumption in general, as well as one of the main barriers for the complete acceptance of fish from aquaculture. The main goal of the present study was to determine consumers' liking for both farmed and wild fish and to evaluate the effect of information regarding the species and the method of production (wild capture/aquaculture) on it.Two groups of approximately 300 participants each consuming fish at least twice a week with similar socio-demographic distributions were recruited in three Spanish regions. four different species (black spot sea bream, gilthead sea bream, sea bass and turbot), each of them from both wild capture fisheries and aquaculture, were evaluated by the two groups of participants. Within each species samples were obtained simultaneously and were frozen until their evaluation for a maximum of 1 month. One group of individuals evaluated the fish samples in a blind condition and the other in an informed condition.A significant effect of species was detected in both cases, although similar liking profiles were observed in the informed and blind conditions. The mean liking scores of sea bass, turbot and gilthead sea bream did not differ, and these species were significantly more appreciated than black spot sea bream. Information provided to consumers had a significant effect on hedonic evaluation of the fish samples. Therefore, in the informed condition, participants preferred wild fish but, interestingly, when information was not provided to them, the scenario was the opposite. It is worth mentioning that farmed fish was similarly evaluated in both the informed and blind conditions, whereas the liking of wild fish significantly increased when information was provided to consumers. These results seem to indicate that farmed fish per se does not have a negative image among consumers but also indicate the existence of a generalised positive attitude towards wild fish. A significant influence of consumer beliefs about farmed versus wild fish was observed in the informed condition.These findings constitute a valuable insight and provide an optimistic scenario for the aquaculture sector given that the improvement of the sensory characteristics of farmed fish does not seem to be necessary. However, providing consumers with reliable information that helps them to value the two types of fish based on scientific evidences would be needed.Statement of relevanceThe farmed fish sensory quality does not need to be improved.
