All ionoregulating marine fishes examined to date utilize seawater-type ionocytes expressing the apical Cl- channel, cystic fibrosis transmembrane conductance regulator (Cftr) secrete Cl−. We performed transcriptomic, molecular, and functional studies identify Cl− transporters in of sea lamprey (Petromyzon marinus). Gill cftr expression was minimal or undetectable larvae post-metamorphic juveniles. identified other highly expressed gills and/or upregulated following metamorphosis further...
Abstract It is unknown whether and how osmoregulation controlled by corticosteroid signaling in the phylogenetically basal vertebrate group Agnatha, including lampreys hagfishes. known that a truncated steroid biosynthetic pathway produces two predominant circulating corticosteroids, 11-deoxycortisol (S) 11-deoxycorticosterone (DOC). Furthermore, express only single, ancestral receptor (CR). Whether S and/or DOC interact with CR to control still unknown. We examined role of endogenous...
Abstract The aim of this work was to evaluate two functional feeds for the gilthead seabream, Sparus aurata , containing low inclusion microalgae-based products (LB-GREENboost, LB Gb ; and LB-GUThealth, Gh ). Fish (12–13 g) were fed 13 weeks a control diet or one four diets supplemented with both at 0.5% 1%. did not affect specific growth rate survival, but increased feed efficiency by decreasing intake enlarging intestines. hepatosomatic index reduced cortisol levels in plasma, while...
The aim of this work was to evaluate the effects on growth performance, intermediary metabolism and welfare inclusion two commercial microalgae-based ingredients called LB-ChromaBream (LB-CB) LB-ChromaBream-plus (LB-CBplus) in diet gilthead seabream (Sparus aurata) close size. For purpose, fish ~182 g initial body mass were fed satiety (ad libitum) for 41 days with three different diets: (i) CONTROL (CTRL), a commercial-like formulation; (ii) LB-CB diet, 10 % microalgal product; (iii)...
In recent years, a clear emphasis has been placed on replacing fishmeal and fish oil in aquafeeds with other alternative ingredients, including algae, particularly low trophic omnivorous species. This work aimed at evaluating the effects of moderate dietary supplementation green microalga Chlorella fusca growth, metabolism, digestive functionality juvenile thick-lipped grey mullet ( Chelon labrosus ). Fish were fed control diet (CT) or containing 15% C. (C-15) biomass during 90 days. C-15...
This study aimed to evaluate the combined effect of dietary Chlorella fusca and ethanol-inactivated Vibrio proteolyticus DCF12.2 (C + V diet) in Chelon labrosus juveniles, highlighting their nutritional, physiological, morphological effects. The results showed that inclusion C. V. significantly enhanced growth performance feed utilization compared control group. C diet increased fish lipid quality index (FLQ), n-3 polyunsaturated fatty acids, n-3/n-6 ratio, which might be beneficial terms...
Lampreys are the most basal vertebrates with an osmoregulatory strategy. Previous research has established that salinity tolerance of sea lamprey increases dramatically during metamorphosis, but underlying changes in gut have not been examined. In present work, we examined intestinal function metamorphosis and seawater exposure ( Petromyzon marinus). Fully metamorphosed juvenile had 100% survival after direct to 35 parts per thousand (SW) only slight elevations plasma chloride (Cl − )...
Two orthologues of the gene encoding Na+-Cl- cotransporter (NCC), termed ncca and nccb, were found in sea lamprey genome. No Na+-K+-2Cl- 2 (nkcc2) was identified. In a phylogenetic comparison among other vertebrate NCC NKCC sequences, NCCs occupied basal positions within clades. freshwater, mRNA only gill nccb intestine, whereas both kidney. Intestinal levels increased during late metamorphosis coincident with salinity tolerance. Acclimation to seawater intestine Electrophysiological...
Aflatoxin B1 (AFB1) is a mycotoxin often present in food. This study aimed to understand the physiological effects of AFB1 on seabream ( Sparus aurata ) gastrointestinal system. In first vitro approach, we investigated ion transport using short-circuit current (I sc technique Ussing chambers anterior intestine (AI). Application apical/luminal concentrations 8 and 16 μM healthy tissues was without effect tissue transepithelial electrical resistance (TER), apparent permeability (P app measured...
Aquaculture procedures usually induce stress that affects the physiological status of fish. For this reason, inclusion additives in fish feeds to palliate might be a good alternative. This study aimed assess antimicrobial activity citronella (Cymbopogon nardus) essential oil (CEO) against bacterial pathogens and determine its dietary impact on growth performance Sparus aurata. In vitro tests confirmed CEO possesses several fish-specific pathogens. vivo tests, three experimental groups were...
Osmotic costs in teleosts are highly variable, reaching up to 50% of energy expenditure some. In several species, environmental salinities close the isosmotic point (~15 psu) minimize demand for osmoregulation while enhancing growth. The present study aimed characterize physiological status related early juveniles greater amberjack, Seriola dumerili, acclimated three (15, 22, and 36 psu). Our results indicate that plasma metabolic substrates were enhanced at lower salinities, whereas hepatic...
In fish, as observed in mammals, any stressful event affects the immune system to a larger or shorter extent. The neuroendocrine-immune axis is bi-directional network of mobile compounds and their receptors that are shared between both systems (neuroendocrine immune) regulate respective responses. However, how what extent immunity modulates neuroendocrine not yet fully elucidated. This study was carried out understand better central gene expression response patterns high-valued farmed fish...
Several studies in fish have shown that aflatoxin B1 (AFB1) causes a disparity of species-dependent physiological disorders without compromising survival. We studied the effect dietary administration AFB1 (2 mg kg−1 diet) gilthead seabream (Sparus aurata) juveniles combination with challenge by stocking density (4 vs. 40 g L−1). The experimental period duration was ten days, and diet administered to for 85 days prior challenge. Our results indicated an alteration carbohydrate lipid...
