“…However, this is expected since the proximate composition of growing fish is mainly determined by fish size, life cycle stage and energy intake (Shearer, 1994), which did not differ in this study. Similarly for the mineral composition of the carcass, where data for turbot is rare but similar to previous studies (van Bussel et al, 2014;Hoerterer et al, 2022b), and is similar to those of other species (Antony Jesu Prabhu et al, 2016). Differences in the mineral composition are only expected when there are strong deficiencies in the diet (Shearer, 1994) and are further influenced by the mineral concentrations in the rearing water (van Bussel et al, 2014;Antony Jesu Prabhu et al, 2016).…”

“…There were no diet-dependent effects on the proximate composition (N = 20) of the carcass with values within the range of turbot (Dietz et al, 2012;Bonaldo et al, 2015;Fuchs et al, 2015;Bian et al, 2017;Hoerterer et al, 2022b).

“…Similar to salmonids (Hua and Bureau, 2012), this study suggest that the tolerance to FM replacement depends on the group of alternative ingredients. At lower levels of FM replacement, these effects cannot be detected, as shown in the preceding study with smaller turbot (initial BW: 20 g), there were no significant differences between the PAP and PLANT (analogue to NoPAP) formulation concepts (Hoerterer et al, 2022b), which might be contributed to the comparably low FM replacement level of 20%. In order to further explain the differences in protein digestibility and growth further analysis of the amino-acid profile of the diets and a more detailed evaluation of the variability of the nutritional value for the specific fish species could be helpful to optimize the formulation concepts (Glencross et al, 2020).…”

One part of aquaculture sustainability is reducing the environmental footprint of aquaculture feeds. For European aquaculture, this means finding feed ingredients that are produced within the economic community, and that are not in conflict with human consumption. This is especially challenging when formulating diets for carnivorous fish such as turbot with low tolerance to fishmeal replacement that are both nutritious and economically and environmentally sustainable. Therefore, we investigated the effects of two novel and innovative feed formulation concepts on growth and feed performance and the nutritional status of market-sized turbot in a recirculating aquaculture system. In a 16-week feeding trial, 440 turbot (300 ± 9 g) were fed twice a day with a control diet (CTRL), based on a commercial formulation, and four experimental diets. The experimental diets were designed to investigate the effects of two formulations concepts based on sustainable terrestrial plant proteins (NoPAP) or processed animal proteins (PAP) and of 30% and 60% fishmeal replacement with emerging feed ingredients (fisheries by-products, insect meal and fermentation biomass). Turbot from the CTRL group had a similar growth and feed performance than fish fed the NoPAP30 formulation, with a significant decline of performance in the fish fed both PAP formulations and the NoPAP60. Comparing the two formulation concepts with each other the voluntary feed intake and protein efficiency ratio on tank basis as well as the individual weight gain and relative growth rate was significantly higher in the fish from the NoPAP groups than PAP groups. Furthermore, the apparent digestibility of nutrients and minerals was significantly reduced in the fish fed with the diets with 30% and 60% fishmeal replacement level compared to the fish from the CTRL group. In conclusion, the performance of the fish fed the NoPAP30 formulation concept highlights the potential of the used combination of sustainable ingredients, such as fisheries by-products, insect meal, microbial biomass and plant protein for turbot. Furthermore, this study shows that turbot has a higher tolerance to the incorporation of plant and insect protein than of processed animal protein.

European consumers’ beliefs about the main pillars of the sustainability: a comparison between wild and farmed fish

et al. 2023

View full text Add to dashboard Cite

Aquaculture can represent an alternative means of economic yield and food security. Despite this fact, consumers still have a more negative perception of farmed fish when compared with wild fish, including its sustainability. Understanding how consumers perceive sustainability is essential in building an effective strategy to encourage sustainable fish consumption. A survey with 2145 consumers was conducted in five European countries (France, Germany, Italy, Poland, and Spain) to inquire into consumers’ beliefs about the main pillars of the sustainability (environmental, social, and economic) when farmed and wild fish are compared, as well as to identify segments of consumers with similar beliefs about fish sustainability. Overall, results showed that European consumers perceived farmed fish as being more sustainable, locally obtained, providing environmental benefits, generating employment, improving human living conditions, generating rural development, and ensuring more fair fish prices than wild fish. Conversely, wild fish was perceived as ensuring animal welfare and being more organic but causing more environmental damage than farmed fish. Additionally, it seems that to effectively communicate aquaculture sustainability, it would be better to focus on single aspects of sustainability (beliefs) rather than focusing on the whole concept of sustainability. Finally, four segments of consumers were identified according to consumers’ beliefs, which were labelled accordingly: ambivalent, pro aquaculture, pro wild fish, and impartial. Results obtained may be helpful to provide each segment with tailored marketing strategies to stimulate farmed fish consumption and improve the overall image of the aquaculture sector to foster its full development in Europe.

Policy initiatives towards enhancing consumer knowledge and tackling consumer confusion in aquaculture sector

Aquaculture sector is considered an important economic activity both at global and European levels. It contributes in food security, employment, and social cohesion especially in coastal areas. Furthermore, it provides high nutritional value products and plays a significant role in constant supply of fish products in the market. However, major marketing challenges are observed within the sector. Particularly, product communication is considered a major marketing issue as it has been indicated by a plethora of studies. Notably, it has been observed that there is a higher consumer preference of captured fish versus farmed fish, especially in coastal areas. This is due to the fact that there is a substantial consumer knowledge gap regarding aquaculture production process. Interestingly, this is also being observed in organic aquaculture sector, indicating a substantial consumer knowledge gap and consequently consumer confusion unable to identify the added value of organic aquaculture products. Therefore, the present study aims to review the literature regarding consumer knowledge and confusion in aquaculture production. Thus, a scoping review of research was conducted based on systematic search from relevant research, review articles, and online documents. Policy and marketing strategy recommendations are provided on how to improve consumers’ knowledge and consequently how to tackle consumers’ confusion regarding sustainability production practices.
