Abstract

Krill meal (KM) emerges as a promising sustainable marine ingredient in aquafeeds, providing a rich source of protein, amino acids, phospholipids, omega-3 fatty acids, and bioactive compounds. This study aimed to investigate the effects of including KM (3, 5 and 7 % of the diet) on growth performance, nutrient utilization, and antioxidant defenses in juvenile gilthead sea bream ( Sparus aurata) exposed to a crowding stress challenge. The dietary inclusion of 7 % KM could effectively replace up to 47 % FM in the diet (8 % FM in 7 % KM in comparison to 15 % FM in control diet), without compromising growth or feed conversion. Although not statistically different, dietary supplementation with 5 and 7 % KM showed a tendency to further optimize feed conversion ratio and nutrient efficiency ratios compared to the control FM diet. Under stressful conditions, a significant interaction between diet and time was observed in fish blood omega-3 index (O3I). At 24 h after the stress challenge, all dietary treatments except KM3 presented a significant increase in n-3 PUFA, EPA, DHA as well as OI3, whereas a decrease in MUFA. At 7d (168 h) post-stress, fish fed the control diet presented a significant reduction in O3I down to the basal levels. On the contrary, those fish fed KM5 and KM7 diets kept increased O3I levels as well as n-3 PUFA content to the end of the stress challenge. Indeed, 24 h after stress, fish fed KM5 and KM7 showed a lower increase of cat and sod gene expression in head kidney, which was further inversely correlated with fish blood OI3. Therefore, these results show that KM modulates red blood cells fatty acid profile by increasing fish OI3 after stress as well as potentially functioning as an antioxidant modulator in fish feeds for mitigating stressful conditions. Hence, KM is a valuable functional ingredient in aquafeeds, aiming to expand the basket of raw materials with functional properties to be used in aquafeed formulation to enhance fish robustness.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-04-04:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 7.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 7 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

    It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

    • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
