## 6 Discussion  
The main outcome of the investigation is that the majority of all the analyzed segments consider that FAP ecolabels in the EU should not only include environmental issues, but also other types of information. For the majority of the segments of analysis considered, the highest valued issue different from the environmental type was social and ethical issues. The result contrasts with those obtained from an extensive review of fisheries/aquaculture ecolabel schemes which found that only a small number deal directly with social issues, and even those schemes that include this type of information with some policy statements and general principles which mention social issues unanimously give far more emphasis to the environmental issues [58]. In fact, for example, the MSC ecolabel, which covers about 10% of total seafood catch globally [23], strongly emphasizes environmental information over social issues. In addition, another investigation contends that although it has been widely accepted since the 1990s, sustainability is based on three pillars (economic, environmental and social); in reality, the economic and environmental aspects have tended to dominate the sustainable agenda and social aspects have been neglected [59]. Furthermore, progress in the ethics of seafood can be accomplished through government regulations and the participation and cooperation of the seafood industry and civil society in establishing acceptable ethical standards and performance benchmarks [30]. Furthermore, ethical concerns for people, fish and the environment should be addressed along the entire supply chain of seafood goods, considering that focusing only on growing seafood production systems to tackle global food security could miss food ethics concerns in parts of the logistics chain [30]. Moreover, we also found that for the majority of the segments of analysis considered, the second-highest valued issue other than the environmental type was animal welfare issues. The progress of animal welfare for fish can be accomplished by adopting the five freedoms that should be respected by those who manage farm animals in order to promote animal welfare and to avoid animal suffering [60]. The five freedoms consist of freedom from hunger and thirst, freedom from discomfort, freedom from pain, injury and disease, freedom to express normal behavior and freedom from fear and distress. Furthermore, an investigation found that according to the opinion of different stakeholders, the most relevant elements that influence fish welfare are ensuring a good physiological condition and good feed quality [61]. These two elements facilitate routine monitoring and a safe stock density and are more relevant than other aspects such as husbandry practices, quality of water and quality of the rearing environment. Considering the preferences of consumers, which is the largest sample considered in the survey, our findings of the higher importance of social and ethical issues and animal welfare issues in comparison to health and safety and food quality issues is contrary to the findings of a study in the analysis of the importance of different food shopping criteria in Sheffield, England [62]. The authors found that attributes related to food quality and safety were valued higher than animal welfare and fair trade (ethical issue). However, these comparisons should be done carefully, as it should be noted that our study considers a wider sample of countries apart from England and, most importantly, that the other study focused on general food shopping and not on a specific type of products such as FAPs. Along the same line, our finding that, for consumers, animal welfare issues are more important than health and safety issues contradicts the results of a systematic literature review of studies assessing food label preferences or choices within the context of sustainable diets for diverse food products that include seafood, which found that nutrition-related attributes are preferred to social responsibility attributes related mainly to animal welfare [63].
