3.1. Sample Description
In Italy, 506 females (50.4%) and 497 males (49.6%) completed the survey. Among the respondents, 298 were between 55 and 77 years old (29.7%), 285 were between 30 and 40 years old (28.4%), 241 were between 45 and 54 (24%), and 178 were between 18 and 29 years old (17.8%). A total of 532 respondents held high school diplomas (53%), 298 had bachelor’s degrees (29.7%), 106 were secondary school diploma holders (10.6%), and 32 and 35 had master’s and PhD degrees, respectively (3.2% and 3.5%). In terms of employment, 400 of the respondents were employees (39.9%), 198 were unemployed (19.7%), 113 were freelancers (11.3%), 76 were students (7.6%), and 99 had other professions (9.9%). Regarding their living areas, 515 respondents lived in internal areas (internal areas are typically rural areas that are not along the coast or near the mountains. They often lack access to essential services and infrastructure compared to urban or more developed regions [
60]) (51.4%), 214 lived in seaside cities (seaside cities are urban areas located directly along the coast. They typically have a strong connection to maritime activities, including tourism, fishing, and trade [
61]) (21.4%), 211 lived near the seaside (near the seaside, cities are situated close to but not directly on the coast. They benefit from proximity to the sea and its associated economic and recreational opportunities without being in the immediate coastal zone [
60]) (21.1%), and 60 lived in mountainous areas (mountain areas are regions with a significant elevation and rugged terrain. These areas are crucial for biodiversity, water resources, and cultural heritage. They cover about 27% of the earth’s land surface and are home to diverse ecosystems and communities [
62]) (6%). Most respondents, 784, did not have children (78.2%). The dietary preferences included 832 omnivores (82.9%), 62 pescatarians (6.2%), 55 flexitarians (5.5%), 21 vegetarians (2.1%), 7 vegans (0.7%), and 27 with diets related to personal food allergies and preferences (2.7%) (

Appendix A).
In Spain, 503 males (50.3%) and 497 females (49.7%) completed the survey. Among the respondents, 350 were between the ages of 55 and 77 (35%), 261 were between 30 and 40 years old (26.1%), 150 were between 45 and 54 years old (15%), and 239 were between the ages of 18 and 29 (23.9%). A total of 394 respondents had a high school diploma (39.4%), 378 had bachelor’s degrees (37.8%), 110 had secondary school diplomas (11%), and 118 had Master’s or PhD degrees (11.8%). Regarding employment, 395 respondents were employees (39.5%), 207 were unemployed (20.7%), 84 were freelancers (8.4%), 97 were students (9.7%), and 108 worked in other fields (10.8%). In terms of living area, 407 respondents lived in internal areas (40.7%), 322 lived in seaside cities (32.2%), 227 lived near the sea (22.7%), and 44 lived in mountainous areas (4.4%). Additionally, 330 respondents did not have children (33%). Most respondents, 542, were omnivores (54.2%). (

3.2. Average Best–Worst Score Analysis
The BW score was calculated by subtracting the number of times each attribute was rated as worst (W), least important, from the number of times it was rated as best (B), most important. This score was then divided by the total number of respondents (n) in the sample to determine the average BW score, represented as (B–W)/n.
Table 2 and
Table 3 provide a summary of the best-to-worst scores for Italian and Spanish consumers. Italian consumers selected freshness, smell/appearance and taste/consistency as the most important attributes when making their decision. Italians rely on intrinsic product properties when making their choices. Generally, freshness is a key determinant in influencing fish consumption [
21,
63]. Consumers associate fresh fish with fewer health risks and minimal use of hormones and drugs during the production process. We found that Italian consumers rely on their own judgement rather than trust information provided by sellers (origin, production method, seasonality, price, fish species). Then, the attribute of sustainable fishing scored lower, suggesting that it is of secondary interest.
Conversely, Spanish consumers selected fish species, followed by farmed fish and cleaned/filleted traits, as the most important attributes when choosing fish. The exposure of Spanish consumers to fish might be the reason behind their huge interest in fish, its production method, and its commodity of use [
64]. Spanish respondents placed a high value on fish that was ready to be cooked. In addition, farmed fish is usually more available compared to wild-caught alternatives, as it is accessible all year round and does not depend on seasonality [
65]. Consumers may have an attitude–behaviour gap and choose the most convenient option over the fresh one [
19,
66]. Furthermore, price ranked fourth after the cleaned/filleted attribute. Although price is usually important, in this case the respondents were willing to pay more when more benefits were perceived, as quicker preparation, fitting the demands of modern lifestyles.
Globally, we can see that Italian and Spanish consumers have diametrically opposed preferences. While Italians ranked top in terms of sensory product qualities and freshness, Spanish consumers ranked lowest. Likewise, Spanish people scored higher for fish species, farmed fish, and cleaned/filleted features compared to Italians. Results yielded a lower importance for intrinsic characteristics by Spanish consumers that may be attributable to their higher familiarity with the product [
67].
3.3. Cluster Analysis
In Italy, four groups of consumers were defined as: “Coastal consumers”, “Traceability enthusiasts”, “Sensory sensitive consumers”, and “Convenience enthusiasts” (
Table 4 and
Table 5).
The first group of Italian consumers were dubbed “
Coastal consumers” (29% of the sample). The most significant positive attributes identified for this group were freshness (2.92), physical state (1.2), and being wild-caught (1.24). While seasonality was of lesser concern (−0.94). This cluster mainly lives in a seaside city or near the seaside (2.3). The positive perception of freshness, wild-caught, and physical state attributes suggests a preference for locally sourced seafood. However, their lower concern for seasonality (−0.94) may indicate a preference for consistent availability over seasonal variation. In line with previous studies by Murray et al. (2017) [
20] and Temesi et al. (2020) [
68], exposure, particularly during childhood, influences consumers to continue eating fish throughout their lives and makes them more discerning about the attributes they personally value. The main pattern characterizing fish consumption is linked to proximity to the seaside, as people living near the sea generally have a higher fish consumption compared to inland residents [
33,
69,
70].
Coastal consumers considered price non-significant when buying fish; the high income of individuals in this group made them less sensitive to the expensive nature of fish. Although previous studies demonstrated the importance of price when buying fish [
22], dietary habits appear to exert greater influence than price when consumers make decisions about purchasing fish [
20,
71]. As the most significant consumers of fish among the identified clusters, seaside residents have a unique opportunity to embrace diversified fish-eating practices. Marketers can leverage this proximity to the ocean by promoting a variety of locally sourced fish and seafood options. This not only supports sustainable fishing practices but also encourages a richer and more diverse diet. By highlighting the freshness, health benefits, and culinary versatility of different species, marketers can inspire seaside communities to explore new and exciting ways to enjoy their abundant marine resources”.
The second Italian consumer group, “
Traceability enthusiasts” (13% of the sample), valued quality label (1.93), and sustainable fishing (2.26) the most, while they were less interested in whether fish was cleaned/filleted (−2.21), whether fish is farmed (−1.01), and price (−2.11). In addition, consumers in this group had the highest average for fish preference (8.3) and fish frequency (5.4) consumption compared to all other segments. Traceability enthusiasts regrouped people who were older people (2.8), with large families (3.0), and living near the seaside (2.5). A clear connection between price and ecolabelling does exist, in line with previous studies where consumers were willing to pay more for an eco-labelled or socially responsible product [
27,
72]. In addition, this group’s interest in fishing can be attributed to a demand for a quality label that generally guarantees ethical exploitation of marine resources and sustainable fishing practices [
73]. Furthermore, in line with previous studies, consumers’ interest in fish attributes is strongly driven by biological and socio-demographic factors, with older individuals being most likely interested in fish labels and product safety due to higher health concerns and sustainability claims [
74,
75].
The third group of Italian consumers, “
Sensory-sensitive consumers” (35% of the sample) was the largest. Sensory-sensitive consumers show the highest appreciation for smell/appearance (1.91), taste/consistency (1.55), and price (0.88). These attributes play a crucial role in their decision-making process, highlighting a preference for sensory appeal and affordability. In contrast, they place less emphasis on factors such as sustainable fishing practices (−0.54), wild caught status (−0.12), seasonality (−0.55), farmed fish (−0.75), catch area (−0.24), and specific fish species (−1.40). This suggests that while sensory qualities and cost are significant influencers for this group, consumers in this cluster are less motivated by environmental concerns when making purchasing decisions [
76,
77]. This could be due to a lack of trust or knowledge about certain catch areas or a general indifference to the geographical origin of the products. The low educational level in this group may also contribute to the lack of interest in sustainability-related attributes. Previous studies by Can et al. (2015) [
78], Uddin et al. (2020) [
79], and Myrland et al. (2000) [
80]. Thus, educating consumers by promoting underutilized fish species throughout mass and social media could help to revive the consumption of forgotten or cheaper fish species currently neglected due to health claims around popular fish species [
14,
81].
Lastly, the fourth group of Italian consumers, “
Convenience enthusiasts” (23% of the sample), place a strong emphasis on convenience, as indicated by their positive preference for cleaned and filleted fish (0.16). They prioritize convenience over freshness (1.15), which is of lesser concern to them compared to other clusters. They also show a low concern for farmed fish (−0.75), and they exhibit less interest in fish species (−0.55) and catch area (−0.24) compared to the other attributes, suggesting that while they value convenience, they are also somewhat discerning about the types and origins of the fish they consume. Additionally, they had the lowest preference (6.4) and consumption frequency (4.5) of fish among all clusters, leading to their lower seafood product requisitions.
Convenience enthusiasts were the youngest and had the lowest income level compared to the other groups. Many scholars demonstrated a generational gap in consumers’ food preferences, as younger people were found to be more open in their fish consumption habits [
19,
82,
83]. Furthermore, higher income levels were generally associated with higher dietary fish intake [
84].
In Spain, four groups of consumers were defined as: “Value-Conscious Consumers,” “Affluent Convenience Enthusiasts,” “Quality-Indifferent Consumers” and “Sustainability-Conscious consumers” (
Table 6 and
Table 7).
The first group of Spanish consumers were “
Value-Conscious Consumers” (27% of the sample). These consumers highly value the price (1.86) and the convenience of cleaned/filleted fish (1.80). Physical state (0.50) and seasonality (0.01) are also important, though to a lesser extent. Conversely, they place less emphasis on quality label (−1.54), taste/consistency (−0.60), smell/consistency (−0.56), sustainable fishing (−0.43), and catch area (−0.18). This group had the highest preference for and consumption of fish compared to other groups, suggesting that they prioritize affordability and convenience over quality indicators and sustainability factors, in line with findings from Cantillo et al. (2020) [
10], Saidi et al. (2022) [
9], and Onyeneke et al. (2020) [
85]. To effectively engage
Value-Conscious Consumers, marketers should emphasize affordability and convenience, highlight competitive pricing, offer promotional deals, and display pre-cleaned and filleted fish products. Ensuring products are visually appealing and well-maintained will also cater to their preference for physical state. While seasonality is less important, introducing seasonal varieties can add novelty [
86].
The second group of Spanish consumers, termed the “
Affluent Convenience Enthusiasts” (24% of the sample), positively valued catch area (0.11) and cleaned/filleted fish (1.05), indicating a preference for convenience and knowing the origin of their fish. They valued less freshness (−2.74), seasonality (−0.39), taste/consistency (−1.78), and smell/appearance (−1.95). Additionally, this cluster showed the second-highest preference (8.00) and consumption (5.97) of fish out of the four clusters and had the highest income levels compared to the other identified clusters. In line with previous studies highlighting the importance of income level for consumers fish choice [
78,
79,
84], the effect of price, found to be significant for this cluster, seems to overlap with the level of income, suggesting that
Affluent Convenience Enthusiasts prioritize practical aspects and convenience over sensory qualities and freshness, potentially seeking consistent and easily prepared options rather than high-quality or seasonal products. To effectively engage “Affluent Convenience Enthusiasts,” marketers should emphasize the convenience of cleaned and filleted fish and promote the traceability of the catch area. Offering premium, ready-to-cook meal options can cater to their high income levels and preference for ease. Additionally, educational content on the benefits of freshness and quality can gradually shift their perceptions towards healthier and more conscious fish choices rather than focusing on consistent and easily prepared options.
The third group of Spanish consumers, dubbed “
Quality-Indifferent Consumers” (23% of the sample), value less cleanliness and filleting of fish (−0.43), quality labels (−0.65), catch area (−0.13), and freshness (−1.09). This group preferred whole fish compared to filleted fish products. They also had the fewest children in their households (1.55), indicating their practical and potentially adult-focused meal preferences. In addition, this group lived mainly in inland and mountainous areas where fish supply is more challenging compared to seaside areas [
87].
Quality-Indifferent Consumers preferred (6.15) and consumed (4.65) fish the least compared to the other clusters. Similar to Cantillo et al. (2020) [
10], Smith et al. (2017) [
88], and Liu et al. (2015) [
89], those with more kids are more careful about increasing fish consumption and its quality and safety. Large families also often prioritize budget-friendly food options [
85,
90,
91]. Therefore, focusing on the value-for-money aspect of fish products while ensuring they meet taste and quality expectations can encourage
Quality-Indifferent Consumers to increase their fish consumption. Since cleaned and filleted fish are less appealing to this group, offering whole fish or minimally processed options at lower prices may better align with their preferences and make fish more attractive. Improving the availability and distribution of affordable fish products in inland and mountainous areas is crucial, as residents far from the coast often encounter challenges accessing seafood [
33].
The fourth and last group of Spanish consumers were dubbed “
Sustainability-Conscious Consumers” (26% of the sample). They valued fish species (1.73) the highest, followed by quality labels (0.74), cleaned/filleted fish (0.45), physical state (0.25), and catch area (0.17), indicating a preference for knowing the origin of their fish. They also valued sustainable fishing (0.08). However, they placed a significant negative value on price (−2.27), suggesting a lower focus on affordability when making their decision. Sensory attributes such as taste/consistency (−1.39) and smell/appearance (−1.31) were less valued by this group. The lower income levels (2.03), smaller family sizes (2.86), and higher number of children (1.78), further underscore their focus on sustainable eating choices. This behaviour reflects a practical approach that emphasizes sustainability and essential qualities over cost and sensory attributes, aligning with their family-oriented consumption patterns and financial constraints, in line with previous findings by Bronnmann et al. (2018) [
92] and Onyeneke et al. (2020) [
85]. To better approach this group, marketers should highlight fish species and quality labels through clear labelling and educational campaigns, emphasizing catch areas and sustainable practices. Offering family-oriented promotions like value packs and cooking workshops can cater to their practical needs. Building trust through storytelling and customer testimonials, and engaging them with tasting events and interactive content, will create a more personal connection.
In Italy, all four clusters considered freshness a fundamental element in their purchasing decisions. This outcome could be due to an overlap between sensory attributes, physical features, and freshness, as previous scholars have found out the importance of fresh fish and its association with several intrinsic and extrinsic traits like health aspects, taste, quality, and origin in shaping consumers’ preferences [
9,
70,
93,
94]. “Convenience enthusiasts,” on the other hand, were less interested in the freshness of fish. This could be due to the typology of consumers in this segment, who are younger and considered healthier and therefore less concerned about what they eat or do not perceive any important attribute in that innovative product [
71,
95]. While Spanish consumers did attach importance to the freshness and sensory characteristics of fish, their decision-making depended more on the type of fish, the production method, and convenience. The choice of Spanish consumers could be related to the availability of seafood in Spain, as Spain is one of the most important European fishing countries in terms of production, employment, fleet, consumption, and aquaculture [
96,
97].
