“…Finally, for the stunning process in a stunning tank, the values determined by the desirability function corroborate with Cottee and Petersan (2009). They state that for a stunning, the fish must remain for 10 to 20 min at a maximum temperature of 1.0°C.…”

The present study aimed to characterize the disaggregated fillets and determine the optimal quality parameters used in the pre‐slaughter management of Nile tilapia in the processing industries. The study was carried out in three stages: the first characterized the disaggregated fillet, the second determined the influence of season on the incidence of disaggregated fillets, and the third developed a desirability function to reduce the incidence of disaggregated fillets in the fish slaughter industry. It is believed that the disaggregated fillets are similar to PSE meat, and the influence of the season on their incidence was found in this study; that is, the summer influences the pallor of the tilapia fillet (summer: standard L* = 53.17 ± 0.43 and pH 6.22 ± 0.03; disaggregated L* = 57.54 ± 0.65 and pH = 6.14 ± 0.03 ‐ winter: standard L* = 41.53 ± 0.48 and pH 6.31 ± 0.02; disaggregated L* = 49.07 ± 0.61 and pH = 6.01 ± 0.04), as well as chicken and pork meats, whose values are determined by the L* color parameter and the pH, inversely proportional greatnesses. The incidence of disaggregated fillets is closely related to the management that precedes slaughter, so a desirability function was created to determine optimal values for quality standards of operations immediately before the slaughter of the animal. Novelty impact statement Characterizing Nile tilapia fillets as meats PSE according to the summer and winter seasons. Standardized pH and L* parameter values as determinants for PSE meats in Nile tilapia. Antemortem stress and temperatures influenced the determination of the disaggregated fillets.

“…Consumer preferences are driven increasingly by ethical issues, especially for intensive cage culture of carnivorous fish (Ellingsen et al, 2015; Solgaard & Yang, 2011). If the sector wants to improve the acceptability of farmed products, the industry should not ignore issues such as animal welfare (Alexander et al, 2016; Burbridge et al, 2001; Cotee & Petersan, 2009; Honkanen & Olsen, 2009; Huntingford et al, 2006) and environmental sustainability (Bjørklund et al, 2007; Fernández‐Polanco & Luna, 2010, 2012). Some ethical aspects in aquaculture have drawn special attention, including selective breeding, feeding (e.g., the extensive use of environmental resources based on fishmeal and fish oil), acute stress generated by crowded fish cages, and the impact of fish escapes on wild population (Atalah & Sanchez‐Jerez, 2020).…”

In some food production systems, sustainability and acceptability are considered umbrella concepts that can be assessed through a combination of criteria and indicators. After a remarkable and somewhat chaotic development in the early '90s, European aquaculture has been evolving in both scientific and policy domains to improve, and to prove, its sustainability. The updated review of the literature and policy framework presented in this contribution highlights gaps in European studies, addressing mostly concerns over the environmental impacts and food safety and less in terms of economic impacts on other coastal activities or the effects on social values and local traditions. The analysis of the legislative framework demonstrates that the existing legislation adopted at different levels addresses most of the criteria of social acceptability through binding rules and supporting guidelines. Nonetheless, some elements of social concerns, such as the impact of escapes or the degradation of the landscape, remain unaddressed. A number of actions are proposed that should be implemented by all the actors involved in aquaculture management to improve social attitudes and thus, the acceptance by the different segments of the society.

“…Specifically, the stocking density shall provide for the comfort and well‐being of the animals which, in particular, shall depend on the species, the age of the animals and their behavioural needs. This could affect other parameters including water quality and the impact on the environment, and consequently the animals’ well‐being and growth (Cottee & Petersan 2009). The low stocking densities are desirable in organic aquaculture because, as with many other disease or parasitic infections, infestation levels are host‐density dependent.…”

“…Thus, research has not determined clearly the proportions of aquatic and plant origin that should be used in organic feed. This aspect is of great importance especially for the culture of carnivorous species that dominate European aquaculture (Tacon & Brister 2002; Cottee & Petersan 2009). Research on enteroproteins, an Ento‐protein from insects, is developing to replace fishmeal in the future (Bergleiter et al.…”

Organic aquaculture has lagged behind the agriculture sector in terms of the quantities and diversity of certified organic products because of the absence of detailed accepted standards and criteria until recently. The main challenges for organic aquaculture are to improve the coordination between production and market and to achieve an appropriate framework to drive further development. Priorities for research include organic feeds and fish nutrition, consumers’ needs, food safety, environmental concerns and trade issues. In organically cultured fish, differences in feeds and nutrition compared to conventional systems are likely to result in differences in the quality of the flesh, and this is a significant factor in consumer choice. The review covers aspects of current use of eco‐certification, formulated feeds, feed composition, aquafeed technology, sustainable alternatives to common feed ingredients, nutritional physiology and general nutritional principles and product quality in the context of the organic aquaculture. There is a future for the development of organic aquaculture but its success depends on new knowledge and technical development to meet consumers’ growing interest. The industry has to utilize the research results and update and modify the criteria and standards and thus provide high‐quality products.
