Abstract Background The basic function of the immune system is to protect an organism against infection in order minimize fitness costs being infected. According life-history theory, energy resources are a trade-off between costly demands immunity and other physiological demands. Concerning fish, both physiology influenced by seasonal changes (i.e. temporal variation) associated abiotic factors (such as primarily water temperature) interactions with pathogens parasites. In this study, we...
This study analyses diploid and hydrostatic-pressure-induced triploid brook trout (Salvelinus fontinalis) sampled from a fish farm before (360 days post-hatch, d.p.h.) during the normal time of sexual maturation for pan-sized market (555 667 d.p.h.). Biometric indices slaughtering traits examples both ploidy levels were compared their genomic heterozygosity gonadal development evaluated to assess possible link between these two parameters growth performance. At 555 d.p.h., triploids –...
Although the unique features of asexual reproduction and hybridization among European spined loaches (genus Cobitis ) have recently attracted attention conservation biologists, faunists evolutionary research has suffered from uncertain identification specimens their genomes because extreme morphological similarity all species within hybrid complex. In this article, a Europe‐wide study is reported, which was performed on samples collected by several teams. Several complementary methodologies,...
One of the five basal actinopterygian lineages, Chondrostei, including sturgeon, shovelnose, and paddlefish (Order Acipenseriformes) show extraordinary ploidy diversity associated with three rounds lineage-specific whole-genome duplication, resulting in levels sturgeon. Recently, incidence spontaneous polyploidization has been reported among cultured sturgeon it could have serious negative implications for economics farming. We report occurrence seven heptaploid (7n) Siberian Acipenser...
The goal of this study was to determine the basic haematological profile common carp (Cyprinus carpio L.) spawners eight breeds reared under identical conditions and sampled in spring after overwintering. Significant differences were found among for haemoglobin level (Hb), haematocrit value (PCV), mean corpuscular volume (MCV) (MCH) values. number red blood cells (RBC), concentration (MCHC), leukocytes (WBC) leukocyte differential count (WBC DIFF) did not differ significantly respective...
Genome duplications and polyploidization events are thought to have played relevant roles in the early stages of vertebrate evolution, particular near time divergence lamprey lineage. Additional genome duplications, specifically ray-finned fish, may occurred before teleosts. The role evolution is a thriving area research. Sturgeons (order Acipenseriformes) provide unique model for investigation duplication, with existing species possessing 120, 250 or 360 chromosomes. In present study, data...
Evolution of sturgeons and paddlefishes (order Acipenseriformes) is inherently connected with polyploidization events which resulted in differentiation ploidy levels chromosome numbers present acipenseriform species. Moreover, allopolyploidization as well autopolyploidization seems to be an ongoing process these fishes individuals abnormal were occasionally observed within sturgeon populations. Here, we reported occurrence Siberian (Acipenser baerii) male level for this species, accessed its...
Albinism is a widespread departure from typical body colouration due to altered melanin production. The Wels catfish (Silurus glanis) among the largest freshwater fish species in world, and albino individuals occur both wild aquaculture. Here, we performed transcriptome-wide analysis of normally pigmented S. glanis using four tissues (skin, dorsal fin, whole eye liver) identify genes associated with albinism by exploring patterns differential expression (DE) alternative splicing (DAS)....

Genomic GC content can vary locally, and GC-rich regions are usually associated with increased DNA thermostability in thermophilic prokaryotes warm-blooded eukaryotes. Among vertebrates, fish amphibians appeared to possess a distinctly less heterogeneous AT/GC organization their genomes, whereas cytogenetically detectable heterogeneity has so far only been documented mammals birds. The subject of our study is the gar, an ancient "living fossil" basal ray-finned lineage, known from Cretaceous...
Acipenseriformes is a basal lineage of ray-finned fishes and comprise 27 extant species sturgeons paddlefishes. They are characterized by several specific genomic features as broad ploidy variation, high chromosome numbers, presence numerous microchromosomes propensity to interspecific hybridization. The presumed palaeotetraploidy the American paddlefish was recently validated molecular phylogeny Hox genes analyses. A whole genome duplication in estimated at approximately 42 Mya found be...
