## 7 Conclusions  
This study presents a hybrid fuzzy method that analyzes the coverage of a hypothetical EU ecolabel for fishery and aquaculture products (FAPs) by integrating a synthetic indicator that allows for determining different segments of analysis, the level of acceptance for the inclusion of different types of information apart from environmental issues. The segments of analysis considered were selected according to the different stakeholder groups and whether the citizens do or do not agree with governmental eco-labeling control. The results indicate that ecolabels should provide information not exclusively on environmental issues but also on other types of information, of which social and ethical issues are the most relevant, followed, in order, by animal welfare, health and safety and food quality issues. Almost all the segments of analysis equally ranked the issues, with the exception of producers. For this segment, it is more important to provide information on health and safety and food quality issues. Moreover, the findings show that consumers, producers and citizens who support the control of ecolabels by public bodies or governments have a higher level of acceptance to include other additional information apart from environmental issues. The results indicate that the synthetic indicator is mostly inelastic with respect to all the issues and segments of analysis, with the exception of the pair ecolabel owners and social and ethical issues. On the other hand, the lowest elasticity value was obtained on food quality issues for ecolabel owners. The results of this investigation are based on the public consultation made in the European Union in which the respondents pointed out many concerns towards the proposition of a new EU ecolabel. These concerns should be further analyzed in future investigations that aim to guarantee the total success of a future EU ecolabel for FAPs. It is likely that the origin of these concerns is due to the existing eco-labeling systems in use in the EU. One of these concerns was related to the confusion that the term ecolabel might bring, considering that according to regulation 834/2007, the abbreviation \"eco\" to food products relates to organic production in certain member states [64]. In addition to this, a lack of transparency in the market exists because consumers do not have enough knowledge about the term [65]. Another concern that was highlighted is that a future EU ecolabel for FAPs should be independently developed for different species of fishery and aquaculture products considering the extreme differences that can exist between them. Finally, the most important concern raised in the public consultation is that, as many citizens pointed out, there are already many ecolabels on the market and that they do not see any benefit in adding a new one given that it would create even more confusion for consumers, and therefore, they recommended, as a much better approach, to improve the existing regulations on the current eco-labeling schemes. On the other hand, curiously, other citizens expressed that it would be beneficial to add a label with EU standards that could help consumers to reduce their confusion and the lack of credibility of the current market ecolabels. [PERSON] [66] analyzed the eco-labeling competition issue theoretically through a dynamic Bertrand duopoly in which two eco-labeling programs (sponsored by the industry or by an environmental NGO) compete strategically in setting the ecolabel features. The author found that competition between the programs may lead to the same high environmental benefits in comparison to when only the NGO program exists, and that competition may yield a higher social welfare.
