Abstract	Low levels of docosahexaenoic acid (DHA) in the brain have been related to neurological disorders, like Alzheimer's disease (AD). After ingestion, dietary DHA must cross the blood-brain barrier, where it is absorbed as lysophosphatidylcholine (LPC), due to its role as a preferential DHA carrier in the brain. This work aimed at the production of LPC-DHA extracts to be used in supplementation/food fortification intended neural enrichment in DHA. As it is rich in DHA, especially its phospholipids (PL), Atlantic mackerel (

Abstract	Alzheimer's disease (AD) is a complex and progressive disease, which affects millions of people around the world. Despite the many efforts over the years to find efficient therapeutics, there is no cure yet. Nonetheless, many compounds have been proven to decrease Alzheimer's symptoms. After a short overview of the hypotheses considered in AD drug development and the drugs approved for AD treatment, which lead to symptom release, we focus on the valorization of natural marine sources that decrease AD symptoms, particularly on docosahexaenoic acid (DHA), an important component in membrane phospholipids and the most abundant n-3 polyunsaturated fatty acids (PUFA) found in gray matter of the brain and in retina and on the DHA-containing phospholipids (DHA-PLs) present in marine sources, namely fish, krill, mollusks and in fisheries and aquaculture by-products. DHA-PLs' bioactivities are presented, namely their properties in anti-neurodegeneration, neuroinflammation, as anticancer agents, as well as their benefits to obesity and visual problems. Fisheries and aquaculture by-products are also highlighted as they have a high content of DHA and DHA-rich phospholipids, can be extracted by green methodologies and should be considered in a circular economy for a healthy sustainable future.

Abstract	Currently valorization of fish discards by-products is becoming fundamental for the sustainable management of fisheries and seafood transforming industries. Thus, we have studied the changes in the production and chemical properties of fish protein hydrolysates (FPH) and oils from by-products (heads (He) and skins + bones (SB)) of gurnard (Trigla spp.) captured at different seasons. Hydrolyses were performed by Alcalase (2.5 mL/kg of by-product) at pH 8.60, 60.6 °C, 200 rpm, for 3 h. Seasonality effect was not significant in the majority of FPH properties, obtaining high digestion yields and excellent amino acid contents (more than 43% of essential amino acids per total amino acids in He). However, the maximum degree of hydrolysis for He were higher (24-26.5%) than observed for SB (19-23.6%). In the case of oil, concomitantly recovered to the production of hydrolysates, the yield of recovery was largest in SB landing on autumn (89 mL/kg SB) and winter (67 mL/kg SB), and the best content in ω-3 fatty acids was also found in autumn (257 g/kg oil). In general, FPH and oil from gurnard residues were excellent in productive, compositional and nutritional terms, indicating their valuable interest as potential food and nutraceutical ingredient.

Abstract	This paper examined the toxins naturally produced by marine dinoflagellates and their effects on increases in β-amyloid plaques along with tau protein hyperphosphorylation, both major drivers of Alzheimer's disease (AD). This approach is in line with the demand for certain natural compounds, namely those produced by marine invertebrates that have the potential to be used in the treatment of AD. Current advances in AD treatment are discussed as well as the main factors that potentially affect the puzzling global AD pattern. This study focused on yessotoxins (YTXs), gymnodimine (GYM), spirolides (SPXs), and gambierol, all toxins that have been shown to reduce β-amyloid plaques and tau hyperphosphorylation, thus preventing the neuronal or synaptic dysfunction that ultimately causes the cell death associated with AD (or other neurodegenerative diseases). Another group of toxins described, okadaic acid (OA) and its derivatives, inhibit protein phosphatase activity, which facilitates the presence of phosphorylated tau proteins. A few studies have used OA to trigger AD in zebrafish, providing an opportunity to test in vivo the effectiveness of new drugs in treating or attenuating AD. Constraints on the production of marine toxins for use in these tests have been considered. Different lines of research are anticipated regarding the action of the two groups of toxins.

Abstract	This review is a broad overview of species of the genus Zonaria, a relevant taxonomic grouping within the brown algae, considering data regarding the most common species. The article covers: classification, taxonomy, morphology, ecology, biochemical composition, biological activities, extraction procedures, and possible applications are analysed and discussed. The majority of the Zonaria species are distributed worldwide and encompass different environments. There is a total of 18 species, with Z. diesingiana, Z. farlowii, Z. tournefortii, and Z. turneriana being the most studied. However, even these species exhibit significant knowledge gaps. The study of Zonaria seaweeds is also rendered more difficult due to taxonomical uncertainties and the over-reliance on phenotypic traits for the identification of the genus and particular species. The biological traits of Zonaria spp. point to a highly adaptable seaweed; these organisms can modulate nutrient uptake depending on prevailing abiotic and biotic conditions. The study of the biochemical composition of Zonaria species enabled identification of potential bioactive compounds, such as phenols, sterols, fatty acids, and other lipids and lipophilic substances. Furthermore, relevant bioactivities (antioxidant, anti-microbial, and anti-cancer) have been reported in some of the species. The molecules underlying these bioactivities may be extracted through the application of highly innovative green technologies. There are already some studies in this direction, but many more are needed. Possible applications of Zonaria biomass or extracts thereof could encompass human and animal nutrition, but also the plant-stimulant market. The incorporation of Zonaria spp.-derived bioactivities to novel products, e.g., cosmetic, cosmeceutical, nutraceutical, and pharmaceutical applications is also within genuine reach of sustainable utilisation.

Abstract	Aquaculture environments can be hotspots for resistance genes through the surrounding environment. Our objective was to study the resistome, virulome and mobilome of Gram-negative bacteria isolated in seabream and bivalve molluscs, using a WGS approach. Sixty-six Gram-negative strains (Aeromonadaceae, Enterobacteriaceae, Hafniaceae, Morganellaceae, Pseudomonadaceae, Shewanellaceae, Vibrionaceae, and Yersiniaceae families) were selected for genomic characterization. The species and MLST were determined, and antibiotic/disinfectants/heavy metals resistance genes, virulence determinants, MGE, and pathogenicity to humans were investigated. Our study revealed new sequence-types (e.g. Aeromonas spp. ST879, ST880, ST881, ST882, ST883, ST887, ST888; Shewanella spp. ST40, ST57, ST58, ST60, ST61, ST62; Vibrio spp. ST206, ST205). >140 different genes were identified in the resistome of seabream and bivalve molluscs, encompassing genes associated with β-lactams, tetracyclines, aminoglycosides, quinolones, sulfonamides, trimethoprim, phenicols, macrolides and fosfomycin resistance. Disinfectant resistance genes qacE-type, sitABCD-type and formA-type were found. Heavy metals resistance genes mdt, acr and sil stood out as the most frequent. Most resistance genes were associated with antibiotics/disinfectants/heavy metals commonly used in aquaculture settings. We also identified 25 different genes related with increased virulence, namely associated with adherence, colonization, toxins production, red blood cell lysis, iron metabolism, escape from the immune system of the host. Furthermore, 74.2 % of the strains analysed were considered pathogenic to humans. We investigated the genetic environment of several antibiotic resistance genes, including bla

Abstract	Fish discards and by-products can be transformed into high value-added products such as fish protein hydrolysates (FPH) containing bioactive peptides. Protein hydrolysates were prepared from different parts (whole fish, skin and head) of several discarded species of the North-West Spain fishing fleet using Alcalase. All hydrolysates had moisture and ash contents lower than 10% and 15%, respectively. The fat content of FPH varied between 1.5% and 9.4% and had high protein content (69.8–76.6%). The amino acids profiles of FPH are quite similar and the most abundant amino acids were glutamic and aspartic acids. All FPH exhibited antioxidant activity and those obtained from Atlantic horse mackerel heads presented the highest 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, reducing power and Cu²⁺ chelating activity. On the other hand, hydrolysates from gurnard heads showed the highest ABTS radical scavenging activity and Fe²⁺ chelating activity. In what concerns the α-amylase inhibitory activity, the IC₅₀ values recorded for FPH ranged between 5.70 and 84.37 mg/mL for blue whiting heads and whole Atlantic horse mackerel, respectively. α-Glucosidase inhibitory activity of FPH was relatively low but all FPH had high Angiotensin Converting Enzyme (ACE) inhibitory activity. Considering the biological activities, these FPH are potential natural additives for functional foods or nutraceuticals.
