Commercially Exploited Seaweed Species in Africa: Occurrences, Chemical Composition, Current Value Chain and Opportunities for Value Addition

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
Commercially exploited seaweed species in Africa, their biochemical composition, current uses, and value chain are reviewed. Potential value‐addition of seaweed is suggested regionally in Africa amongst countries producing similar seaweed species. ABSTRACT Africa has a wide range of coastal environments that support a diverse array of seaweed species ...

Standardized 16S Meta‐Analysis Reveals Consistent Host‐Associated Patterns in Laminariales Epiphytic Microbiomes

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
An integrated bioinformatic pipeline combining taxonomic, functional, and network analyses revealed host‐driven structuring of macroalgal microbiomes. Phaeophyceae hosted distinct epiphytic communities enriched in chemoheterotrophy and polysaccharide degradation, highlighting metabolic coupling, keystone taxa, and a standardized framework for ...

High Levels of Straying in Returning, Repeat‐Spawning Atlantic Salmon Between Two Neighbouring Danish Rivers

Ecology and Evolution, Volume 16, Issue 7, July 2026.
We studied the seaward and return migration of Atlantic salmon kelts from both wild and hatchery origin in River Skjern, Denmark. Of the 199 tagged animals, 110 reached the ocean (55%). Only 10 kelts were recorded returning after spending more than 1 year at sea.

Ulva lactuca Extract in Confectionery Systems: A Sustainable Approach to Natural Pigmentation, Antioxidant Enrichment, and Sensory Optimization in Fondant and Meringue Matrices

Food Science &Nutrition, Volume 14, Issue 7, July 2026.
This study evaluated the functional potential of Ulva lactuca extract as a natural colorant and antioxidant incorporated into sugar‐based (fondant) and aerated (meringue) confectionery matrices. Extract incorporation significantly enriched total phenolic content—achieving up to 150.95 mg GAE/100 g dry matter in meringues—and surged antioxidant ...

P07 | ULVANS AS AN ECO-FRIENDLY TOOL TO MITIGATE CELLULAR IMPAIRMENT INDUCED BY DEXAMETHASONE IN MYTILUS GALLOPROVINCIALIS

European Journal of Histochemistry
The inadequate treatment of municipal wastewater leads to the constant release into the environment of pharmaceutically active compounds (PhACs). The PhACs can induce multiple biological effects on various aquatic species compromising their welfare ...

Metabolites of Seaweeds as Potential Agents for the Prevention and Therapy of Influenza Infection

Marine Drugs, 2019
Context: Seaweed metabolites (fucoidans, carrageenans, ulvans, lectins, and polyphenols) are biologically active compounds that target proteins or genes of the influenza virus and host components that are necessary for replication and reproduction of the

Chemical composition and 13C NMR spectroscopic charcaterisation of ulvans from Ulva (Ulvales, Chlorophyta)

, 1999
International audienceThe chemical composition and structures of several ulvan extracts isolated from various Ulva species were studied. They were all composed mainly of rhamnose, glucuronic acid, xylose, glucose and sulphate with smaller amounts of ...

Atlantic salmon (Salmo salar L.) kelt rheotaxis and position choice are influenced by flow velocity and turbulence in a regulated river

Journal of Fish Biology, Volume 108, Issue 6, Page 1889-1905, June 2026.
Abstract The migratory behaviour of Atlantic salmon kelts is poorly understood. Due to the Atlantic salmon's considerable socio‐economic and ecological importance, their precipitous population abundance declines, and the population resilience potential of salmon kelts, addressing these knowledge gaps is important.
