One of the main challenges in aquaculture is constant search for sustainable alternative feed ingredients that can successfully replace fishmeal (FM) without any negative effects on fish growth and health. The goal present study was to develop a toolbox rapidly anticipating dynamics following introduction new feed; nonlethal, biochemical, molecular markers provide insights into physiological changes fish. A nutritional challenge by feeding conventional rich FM protein (FM diet) versus an...
Abstract Total protein levels in fish are widely used health and welfare studies, providing a simple accessible measure. However, the multifaceted role of blood proteins makes it sometimes challenging to link total content specific issues, while fractions may offer more precise insights into biology health, particularly farmed species where such data is often lacking. Data were gathered from two experiments involving Dicentrarchus labrax Sparus aurata , key European marine aquaculture. The...
Abstract Understanding the stress responses of organisms is importance in performance and welfare farmed animals, including fish. Especially fish aquaculture commonly face stressors, better knowledge their may assist proper husbandry selection breeding stocks. European sea bass ( Dicentrarchus labrax ), a species with high cortisol concentrations, major this respect. The main objectives present study were to assess repeatability consistency response identify differences liver transcription...
Abstract The large use of fish meal/fish oil in carnivorous feeds is the main concern regarding environmental sustainability aquaculture. Here, we evaluated effects an innovative diet, designed to be (1) environmentally sustainable by lowering marine protein content while being (2) cost effective using alternative raw materials with acceptable and produced on industrial scale, growth performance, gut microbiota composition, health welfare European sea bass ( Dicentrarchus labrax ), a key...
The majority of the genetic studies in aquaculture breeding programs focus on commercial traits such as body weight, morphology, and resistance against diseases. However, studying stress response European seabass may contribute to understanding component its future use select broodstock whose offspring potentially be less affected by handling. A total 865 were used measure weight response. Moreover, a disease challenge experiment with Vibrio anguillarum was conducted subset (332) above fish...
Abstract As aquaculture is nowadays the major fish-food production sector, continuous research undergoing for aquafeeds that could replace conventional fishmeal in order to enhance its environmental and economic sustainability. Fish gut microorganisms might be involved nutrient assimilation thus they are crucial their hosts’ well-being. In this study, bacterial diversity was investigated by16S rRNA gene metabarcoding investigate changes midgut (M) feces (F) microbiota of sea bass...
Viral nervous necrosis (VNN) is an infectious disease caused by the red-spotted grouper virus (RGNNV) in European sea bass and considered a serious concern for aquaculture industry with fry juveniles being highly susceptible. To understand genetic basis resistance against VNN, survival phenotype through challenge test RGNNV was recorded populations from multiple year classes (YC2016 YC2017). A total of 4,851 individuals 181 families were tested, subset (n∼1,535) belonging to 122 genotyped...
The sustainable growth of finfish farming relies heavily on reducing the high ecological footprint sourcing and producing fish feeds that accounts for almost 50% total farming. Sustainable alternatives to fishmeal often pose challenges due presence antinutritional factors nutrient imbalances impair health growth. Screening alternative sources adapting global commodity fluctuations requires modern tools can predict physiological responses early reliably. present study explores first time...
The objective of this study was to evaluate the effect harvest practices and slaughter method on stress, quality shelf life whole fish (gilthead sea bream, European bass red bream) towards development a humane practice. use hook line resulted in significantly lower plasma cortisol glucose gilthead bream. Water temperature at affected concentrations stress indicators (plasma glucose), mainly No significant differences were observed between harvesting methods, regarding appearance, microbial...
Given the pivotal role of Platelet-Activating-Factor (PAF) in atherosclerosis and cardio-protective PAF-inhibitors derived from olive pomace, inclusion pomace fish feed has been studied for gilthead sea bream (Sparus aurata). The aim current research was to elucidate anti-atherogenic properties specific HPLC lipid fractions obtained enriched fed with feed, by evaluating their vitro biological activity against washed rabbit platelets. This study underlines that improves nutritional value both...
There is an increasing demand for the breeding programs to focus on resistance against diseases since treatments or vaccinations increase production costs and, in some cases, they are not available at all. Most of studies virus and bacterial diseases, but limited information parasitic European seabass. A sample infected fish (985) with Lernanthropus kroyeri their parents were genotyped using recently developed MedFISH SNP array. The was selected (selective genotyping) order capture genetic...
Gilthead seabream (\textit{Sparus aurata}) is a teleost of considerable economic importance in Southern European aquaculture. The aquaculture industry shows growing interest the application genetic methods that can locate phenotype-genotype associations with high impact. Through selective breeding, exploit this information to maximize financial yield. Here, we present Genome Wide Association Study (GWAS) 112 samples belonging seven different families collected from Greek commercial company....
There is a growing interest in selective breeding European sea bass (Dicentrarchus labrax), especially regarding family selection based on growth performance. In particular, quantitative trait loci (QTL) identification enhances the application of marker-assisted for genetic improvement production traits. The aims study were to identify potential QTL affecting stress and immunological indicators, body weight, mortality after vibriosis injection as well estimate heritability genetic/phenotypic...
Viral infections of teleost fish have great environmental and economic implications in aquaculture. Nervous necrosis virus (NNV) is a pathogen affecting more than 120 different species, causing high mortality morbidity. Herein, we studied the course NNV experimental infection D. labrax, focusing on survivors which indicated viral carrier state. To determine state labrax head kidney, performed gene expression analysis selected immune-related genes profiled its transcriptome 14 days post...
This study evaluates the genetic diversity of different meagre broodstocks sampled in Greece. A multiplex twelve microsatellite markers was used to genotype 946 fish from eleven stocks and batches for broodstock selection, data calculate population parameters as well investigate differentiation between stocks. The results a relatedness analysis were guiding lines fine-tuned overall evaluation distance stocks, choice candidate breeders some them. approach implemented this uses...
There has been thorough research on the genotype by diet interaction and extent of its impact genetic evaluation, using a partly replaced marine animal protein gilthead seabream. To do that, 8356 individuals were gathered from two batches followed different diets: high-plant-protein containing 85% plant proteins standard commercial one 30% protein. During experiment, body weight, growth fat content recorded. High heritability estimates detected for weight performance content. A small effect...
Ensuring the humane harvest of farmed fish without compromising quality fresh product is paramount to welfare and in meeting consumer demands. Electrical stunning a quick effective way render unconscious it has emerged as suggested method by EFSA OIE. The present study evaluated effects electrical on biochemical processes that lead fillet degradation postmortem, red seabream (Pagrus major). Two distinct conditions (low high) were compared along with conventional (an ice slurry). activity...
The European seabass is one of the main commercial fish produced in Mediterranean marine aquaculture. Recently, its production has been negatively affected by losses due to frequent and recurring outbreaks parasitic, bacterial viral diseases. In recent years, gill parasites Diplectanum aequans Lernanthropus kroyeri are increasingly becoming more dominant contributing significantly observed losses. Genetic improvement for disease resistance represents an important strategy controlling...
