Thermal and nutritional strategies for managing tenacibaculum maritimum in aqua...
Carrilho, Raquel Vaz; Moreira, Márcio Júlio Vicente; Farinha, Ana Paula; Schrama, Denise; Soares, Florbela; Rodrigues, Pedro; Cerqueira, MarcoDisease outbreaks pose a significant challenge in aquaculture, leading to substantial economic losses for producers. Tenacibaculosis, a significant ulcerative bacterial disease caused by Tenacibaculum maritimum, affects a wide range of marine fish species globally. Current disease management relies on antibiotics and chemicals, leading to environmental issues, impaired fish and consumer health, and increased an...
Transcriptomic changes behind Sparus aurata hepatic response to different aquac...
Raposo de Magalhães, Cláudia; Sandoval, Kenneth; Kagan, Ferenc; McCormack, Grace; Schrama, Denise; Carrilho, Raquel; Farinha, Ana PaulaGilthead seabream (Sparus aurata) is an important species in Mediterranean aquaculture. Rapid intensification of its production and sub-optimal husbandry practices can cause stress, impairing overall fish performance and raising issues related to sustainability, animal welfare, and food safety. The advent of next-generation sequencing technologies has greatly revolutionized the study of fish stress biology, all...
Effect of creatine and EDTA supplemented diets on European seabass (Dicentrarch...
Schrama, Denise; Raposo de Magalhães, Cláudia; Cerqueira, Marco; Carrilho, Raquel; Farinha, Ana Paula; Costa, Ana Rosa da; Gonçalves, AmparoThe relatively easy access to fish worldwide, alongside the increase of aquaculture production contributes to increased fish consumption which result in higher prevalence of respective allergies. Allergies to fish constitute a significant concern worldwide. beta-parvalbumin is the main elicitor for IgE-mediated reactions. Creatine, involved in the muscle energy metabolism, and ethylenediamine tetraacetic acid (...
Fish processing and digestion affect parvalbumins detectability in Gilthead Sea...
Schrama, Denise; Raposo de Magalhães, Cláudia; Cerqueira, Marco; Carrilho, Raquel; Revets, Dominique; Kuehn, Annette; Engrola, Sofia; Rodrigues, PedroConsumption of aquatic food, including fish, accounts for 17% of animal protein intake. However, fish consumption might also result in several side-effects such as sneezing, swelling and anaphylaxis in sensitized consumers. Fish allergy is an immune reaction to allergenic proteins in the fish muscle, for instance parvalbumin (PV), considered the major fish allergen. In this study, we characterize PV in two econ...
Gilthead seabream liver integrative proteomics and metabolomics analysis reveal...
Raposo de Magalhães, Cláudia; Farinha, Ana Paula; Blackburn, Gavin; Whitfield, Phillip D.; Carrilho, Raquel; Schrama, Denise; Cerqueira, MarcoThe study of the molecular mechanisms of stress appraisal on farmed fish is paramount to ensuring a sustainable aquaculture. Stress exposure can either culminate in the organism’s adaptation or aggravate into a metabolic shutdown, characterized by irreversible cellular damage and deleterious effects on fish performance, welfare, and survival. Multiomics can improve our understanding of the complex stressed phen...
Data on European seabass fed with methionine-enriched diets obtained through la...
Farinha, Ana Paula; Schrama, Denise; Silva, Tomé; Conceição, Luís E.C.; Colen, R.; Engrola, Sofia; Rodrigues, Pedro; Cerqueira, MarcoThis data article is associated with the research article "Evaluating the impact of methionine-enriched diets in the liver of European seabass through label-free shotgun proteomics". Here it is described the data obtained from proteomic analysis of 36 European seabass juveniles (3 fish x 3 replicate tanks) after 18 days of feeding with experimental diets containing four inclusion levels of methionine (Met): 0.7...
Stressor controllability modulates the stress response in fish
Cerqueira, Marco; Millot, Sandie; Silva, Tomé; Félix, Ana S.; Castanheira, Maria Filipa; Rey, Sonia; MacKenzie, Simon; Oliveira, Gonçalo A.Background In humans the stress response is known to be modulated to a great extent by psychological factors, particularly by the predictability and the perceived control that the subject has of the stressor. This psychological dimension of the stress response has also been demonstrated in animals phylogenetically closer to humans (i.e. mammals). However, its occurrence in fish, which represent a divergent vert...
Fish pathology research and diagnosis in aquaculture of farmed fish; a proteomi...
Moreira, Márcio; Schrama, Denise; Farinha, Ana Paula; Cerqueira, Marco; Raposo de Magalhães, Cláudia; Carrilho, Raquel; Rodrigues, PedroOne of the main constraints in aquaculture production is farmed fish vulnerability to diseases due to husbandry practices or external factors like pollution, climate changes, or even the alterations in the dynamic of product transactions in this industry. It is though important to better understand and characterize the intervenients in the process of a disease outbreak as these lead to huge economical losses in...
Evaluating the impact of methionine-enriched diets in the liver of European sea...
Farinha, Ana Paula; Schrama, Denise; Silva, Tome; Conceicao, Luis E. C.; Colen, Rita; Engrola, Sofia; Rodrigues, Pedro; Cerqueira, MarcoPlant protein sources play an essential role in aquaculture by reducing the use of fish meal to sustainable levels, although further supplementation is needed to fulfill fish nutritional requirements. This work addressed fish growth performance and proteome changes to dietary methionine in European seabass juveniles. A dose-dependent response to methionine (Met) was observed on fish growth consistent with prote...
Cognitive appraisal in fish: stressor predictability modulates the physiologica...
Cerqueira, Marco; Millot, S.; Felix, A.; Silva, T.; Oliveira, G. A.; Oliveira, Catarina; Rey, S.; MacKenzie, S.; Oliveira, R.The role of cognitive factors in triggering the stress response is well established in humans and mammals (aka cognitive appraisal theory) but very seldom studied in other vertebrate taxa. Predictability is a key factor of the cognitive evaluation of stimuli. In this study, we tested the effects of stressor predictability on behavioral, physiological and neuromolecular responses in the European sea bass (Dicent...
