European seabass (Dicentrarchus labrax, Linnaeus, 1758) (L) and gilthead seabream (Sparus aurata, Linnaeus, 1758) (C) muscles were hydrolysated by Alcalase (L, C) and Chymotrypsin (L, C) then hydrolysates were examined and their peptide profiles obtained. A total of 765, 794, 132 and 232 peptides were identified in C, L, C and L, respectively. Although, L and C were expected to have more antioxidant capacity because of their peptide profiles, Alcalase hydrolysates observed in vitro, were slightly higher (TEAC assay for C: 848.11 ± 60.78 μmol TE/g protein). Maximum inhibition of oxidative stress was determined for L (12.8% ± 4.5%) in MDCK1 cell lines. Highest proliferative capacity observed for C (147.0% ± 3.1%) at MTT assay in MDCK1 cell culture. L showed the highest chemopreventive effect with a 40-60% decrease for human colon adenocarcinoma cell line HT-29. This research points out the importance of aquatic sources as raw materials for peptide researches.

(TM) meal is a potential alternative ingredient to plant and fishmeal in aquafeeds due to its high protein content, digestibility, and low environmental impact. However, its low n-3 PUFA (EPA and DHA) content represents one of its main limitations. This study evaluated the effects of replacing fishmeal and plant-derived ingredients (plant proteins and soybean oil) with full-fat TM meal on the growth performance and lipid composition of tissues in juvenile European seabass ().

Aquaculture is crucial for meeting global seafood demand; however, intensification often leads to the development of bacterial diseases that threaten productivity. Dicentrarchus labrax, a key species in European aquaculture, is highly vulnerable to vibriosis, primarily caused by Vibrio harveyi. This study investigates genetic diversity of V.

The energetic costs of being in stressful conditions require the involvement of hormones associated with metabolic support, which may also influence immune function. The present work aimed to explore the links between tryptophan nutrition and metabolic responses in European seabass (Dicentrarchus labrax) held under space-confined conditions, and subsequently submitted to an immune challenge. To study that, two dietary treatments were evaluated, i.

Article Synopsis
  • Genome scans allow researchers to examine genetic variations linked to specific traits, but correlating individual genes with larger functional groups can be challenging.
  • This study focused on around 600,000 SNPs from European seabass populations to identify 96 candidate genes, highlighting the importance of epigenetic influences and connections to domestication-related traits.
  • The research found interactions among candidate genes, particularly in pathways related to "chromatin organization," indicating a significant role for epigenetic mechanisms in the domestication process of European seabass.
