Among vertebrates, teleost fish exhibit a considerably wide range of sex determination patterns that may be influenced by extrinsic parameters. However even for model species like the zebrafish Danio rerio precise mechanisms involved in primary have not been studied extensively. The zebrafish, gonochoristic species, is lacking discernible chromosomes and juvenile difficult to determine. Sequential protandrous hermaphrodite provide distinct gender allow studying process looking at mechanism...
Natural mating and mass spawning in the European sea bass (Dicentrarchus labrax L., Moronidae, Teleostei) complicate genetic studies implementation of selective breeding schemes. We utilized a two-step experimental design for detecting QTL mass-spawning species: 2122 offspring from natural between 57 parents (22 males, 34 females one missing) phenotyped body weight, eight morphometric traits cortisol levels, had been previously assigned to based on genotypes 31 DNA microsatellite markers....
Pinna nobilis populations, constituting the largest bivalve mollusk endemic to Mediterranean, is characterized as critically endangered, threatened by extinction. Among various factors proposed etiological agents are Haplosporidium pinnae and Mycobacterium sp. parasites. Nevertheless, devastation of fan mussel populations still far from clear. The current work undertaken under a broader study aiming evaluate health status population in Aegean Sea, after mass mortalities that occurred 2019. A...
Since the first confirmed records of mass mortality events (MME) in Aegean Sea 2018, Pinna nobilis populations Greek seas have been decimated. To bolster recovery efforts, this study aimed to assess status fan mussel and Ionian investigate potential recolonization through natural recruitment. From May 2022 2023, 163 independent underwater visual surveys were conducted across various locations depths along coastline. A total 4348 P. individuals was recorded, which 87.3% found dead 12.7%...
Pinna nobilis, an ecologically significant and critically endangered bivalve endemic to the Mediterranean Sea, has been classified as “Critically Endangered” by IUCN due habitat degradation, climate change, mass mortality events caused protozoan parasite Haplosporidium pinnae. Effective conservation efforts require robust molecular tools for species identification genetic monitoring, necessitating development of optimized DNA extraction amplification protocols a non-invasive sampling...
Summary Gilthead sea bream ( S parus aurata L.) is an important marine fish in Mediterranean aquaculture. Sex determination by age and/or body weight a critical life‐history trait, the genetic basis for which largely unknown this sequential hermaphrodite species. Herein, we performed partial genome scan to map quantitative trait loci QTL ) affecting and sex using 74 informative microsatellite markers from 10 paternal half‐sib families construct nine linkage groups LG ). In total, four...
Abstract Background In fish, the most studied production traits in terms of heritability are body weight or growth, stress disease resistance, while cortisol levels, widely used as a measure response to stress, is less studied. this study, we have estimated heritabilities two growth (body and length) confinement European sea bass. Findings The F1 progeny analysed (n = 922) belonged small effective breeding population with contributions from an unbalanced family structure just 10 males 2...
In this study, a scale of quality for the body shape Gilthead seabream was developed. For purpose, questionnaire survey carried out to study preferences consumers seabream. Furthermore, variation in reared studied under two rearing environments (sea cages vs. tanks) and comparison with wild-caught individuals. Following test–retest analysis reliability, 22 65 participants presented significant correlation between repeated evaluations same subjects were classified as responders high...
Abstract Background Various endosymbiotic bacteria, including Wolbachia of the Alphaproteobacteria, infect a wide range insects and are capable inducing reproductive abnormalities to their hosts such as cytoplasmic incompatibility (CI), parthenogenesis, feminization male-killing. These extended phenotypes can be potentially exploited in enhancing environmentally friendly methods, sterile insect technique (SIT), for controlling natural populations agricultural pests. The goal present study is...
The meagre, Argyrosomus regius, has recently become a species of increasing economic interest for the Mediterranean aquaculture and there is ongoing work to boost production efficiency through selective breeding. Access complete genomic sequence will provide an essential resource studying quantitative trait-associated loci exploring genetic diversity different wild populations stocks in more detail. Here, we present first genome A. produced combination long short read technologies efficient...
We report a quantitative trait loci (QTL) mapping study on 18 morphometric characters in gilthead seabream based total of 74 informative microsatellite markers genotyped 409 offspring coming from 10 paternal half-sib families. Statistical analysis was carried out using linear regression approach, and various suggestive significant morphology QTL were detected three (9, 21 25) nine linkage groups examined. Fitting body weight as covariate reduced the significance some but revealed new other...

Abstract Constraints on microsatellite length appear to vary in a species-specific manner. We know very little about the nature of these constraints and why they should among species. While surveying variation Mediterranean gilthead sea bream, Sparus aurata, we discovered an unusual pattern covariation between two closely linked loci. One- two-locus haplotypes were scored from PCR amplification products each locus separately both loci together. In sample 211 fish, there was strong negative...
Various factors, including the insect host, diet, and surrounding ecosystem can shape structure of bacterial communities insects. We have employed next generation, high-throughput sequencing 16S rRNA to characterize bacteriome wild Zeugodacus (Bactrocera) cucurbitae (Coquillett) flies from three regions Bangladesh. The tested populations developed distinct with differences in composition, suggesting that geography has an impact on fly bacteriome. dominant bacteria belonged families...
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...
