Eco-innovative aquafeeds biofortified with asparagopsis taxiformis to improve t...
Marmelo, Isa; Lourenço-Marques, Cátia; Silva, Iris A.L.; Soares, Florbela; Pousão-Ferreira, Pedro; Mata, Leonardo; Marques, António; Diniz, Mário SousaExtreme weather events, like marine heatwaves (MHWs), are becoming more frequent and severe due to climate change, posing several challenges to marine ecosystems and their services. As disease outbreaks are often prompted by these acute phenomena, it is essential to develop ecoinnovative strategies that can efficiently improve farmed fish resilience, especially under suboptimal rearing conditions, thereby ensur...
Concise review of the genus Asparagopsis Montagne, 1840
Zanolla, Marianela; Carmona, Raquel; Mata, Leonardo; De la Rosa, Julio; Sherwood, Alison; Barranco, Carlos Navarro; Muñoz, Antonio RománAsparagopsis (Bonnemaisoniaceae, Rhodophyta) species are distributed in most temperate and tropical waters of the world, where they are considered an iconic invader. Despite a low number of species in the genus, Asparagopsis armata and A. taxiformis are considered species complexes, revealing remarkable genetic diversity in native and introduced distribution ranges. Macroscopic life stages that characterize the...
Draft genome sequence of vibrio jasicida 20LP, an opportunistic bacterium isola...
Sanches-Fernandes, Gracinda M. M.; Califano, Gianmaria; Keller-Costa, Tina; Castanho, Sara; Soares, Florbela; Ribeiro, Laura; Pousão-Ferreira, PedroWe present the genome sequence of Vibrio jasicida 20LP, a bacterial strain retrieved from larvae of gilthead seabream (Sparus aurata), a highly valuable, model fish species in land-based aquaculture. Annotation of the V. jasicida 20LP genome reveals multiple genomic features potentially underpinning opportunistic associations with diverse marine animals.
Nitrogen uptake kinetics of an enteric methane inhibitor, the red seaweed Aspar...
Torres, Raquel; Mata, Leonardo; Santos, Rui; Alexandre, AnaThe use of red seaweeds of the genus Asparagopsis as a feed ingredient drastically decreases the enteric methane production by ruminant livestock, thereby reducing the environmental impact of this industry. To address the world demand for Asparagopsis mass production, it is essential to understand the species nutrition. In this study, we evaluated for the first time the uptake kinetics of inorganic and organic ...
Effects of live feed manipulation with algal‐derived antimicrobial metabolites ...
Sanches‐Fernandes, Gracinda M. M.; Califano, Gianmaria; Castanho, Sara; Soares, Florbela; Ribeiro, Laura; Pousão‐Ferreira, Pedro; Mata, LeonardoOpportunistic microorganisms acquired through rearing water or live feed ingestion are believed to underpin high mortality rates of fish larvae, constituting a production bottleneck for the aquaculture industry. We employed 16S rRNA gene sequencing to determine whether treatment of live feed (rotifers and Artemia) with algal-derived, antibacterial metabolites could alter bacterial community structure of gilthea...
Draft genome sequence of Vibrio chagasii 18LP, isolated from Gilthead Seabream ...
Sanches-Fernandes, Gracinda M. M.; Califano, Gianmaria; Keller-Costa, Tina; Castanho, Sara; Soares, Florbela; Ribeiro, Laura; Pousão-Ferreira, PedroWe report the draft genome sequence of Vibrio chagasii strain 18LP, isolated from gilthead seabream larvae at a fish hatchery research station in Portugal. The genome presents numerous features underlying opportunistic behavior, including genes coding for toxin biosynthesis and tolerance, host cell invasion, and heavy metal resistance.

Molecular Taxonomic Profiling of Bacterial Communities in a Gilthead Seabream (...
Califano, Gianmaria; Castanho, Sara; Soares, Florbela; Ribeiro, Laura; Cox, C. J.; Mata, Leonardo; Costa, RodrigoAs wild fish stocks decline worldwide, land-based fish rearing is likely to be of increasing relevance to feeding future human generations. Little is known about the structure and role of microbial communities in fish aquaculture, particularly at larval developmental stages where the fish microbiome develops and host animals are most susceptible to disease. We employed next-generation sequencing (NGS) of 16S rR...
Genetic homogeneity in the seagrass Cymodocea nodosa at its northern Atlantic l...
Alberto, Filipe; Mata, Leonardo; Santos, RuiRandom amplified polymorphic DNA (RAPD) markers were used to analyse the genetic variability of the dioecious seagrass Cymodocea nodosa Ucria (Ascherson) in the Ria Formosa lagoon, Portugal, the species' northern limit in the Atlantic. Three individuals from each of 6 meadows were genotyped with 28 primers. Meadows described previously as having flower marks were compared with meadows where flowers did not occu...
