Effect of ploidy on Salmon physiology - Liver

ABSTRACT: This study investigated firstly, the impact of ploidy on growth performance and whole body composition of Atlantic salmon at different early freshwater stages (34 dph (days post-hatching) alevin; 109 dph; fry and 162 dph parr;) and secondly, whether phenotypic differences at these stages were reflected in the protein samples collectedproteome from whole fish, white muscle or liver tissue. Female diploid and triploid Atlantic salmon (n = 3) were first fed at 35 dph and then maintained by feeding to satiation on commercial feeds.

There is currently renewed interest in farming triploid Atlantic salmon. Improving farming requires identifying triploid specific phenotypic and physiological traits that are uniquely derived from ploidy per se and developed under optimal growing conditions. This study investigated firstly, the impact of ploidy on growth performance and whole body composition of Atlantic salmon at different early freshwater stages [34dph (days post-hatching) alevin, 109dph fry, and 162dph parr] and secondly, whe ...[more]

Molecular characterisation of the Atlantic salmon gill epithelial cell line ASG-10

Project description:Fish gills are not only the respiratory organ, but also essential for ion-regulation, acid-base control, detoxification, waste excretion and host defense. Multifactorial gill diseases are common in farmed Atlantic salmon, and still poorly understood. Understanding gill pathophysiology is of paramount importance, but the sacrifice of large numbers of experimental animals for this purpose should be avoided. Therefore, in vitro models, such as cell lines, are urgently required to replace fish trials. An Atlantic salmon gill epithelial cell line, ASG-10, was established at the Norwegian Veterinary institute in 2018. This cell line forms a monolayer expressing cytokeratin, e-cadherin and desmosomes, hallmarks of a functional epithelial barrier. To determine the value of ASG-10 for comparative studies of gill functions, the characterization of ASG-10 was taken one step further by performing functional assays and comparing the cell proteome and transcriptome with those of gills from juvenile freshwater Atlantic salmon. The ASG-10 cell line appear to be a homogenous cell line consisting of epithelial cells, which express tight junction proteins. We demonstrated that ASG-10 forms a barrier, both alone and in co-culture with the Atlantic salmon gill fibroblast cell line ASG- 13. ASG-10 cells can phagocytose and express several ATP-binding cassette transport proteins. Additionally, ASG-10 expresses genes involved in biotransformation of xenobiotics and immune responses. Taken together, this study provides an overview of functions that can be studied using ASG-10, which will be an important contribution to in vitro gill epithelial research of Atlantic salmon.

Investigation of the host response of naïve Atlantic salmon (Salmo salar) inoculated with Paramoeba perurans prior to the onset of clinical symptoms

Project description:Amoebic Gill Disease (AGD), caused by the ectoparasite Paramoeba perurans (P. perurans) is characterised by hyperplasia of the gill epithelium and lamellar fusion and has become recognised as one of the most significant health threats in salmon farming . In this study, the gill and serum proteomes of Atlantic salmon inoculated with P. perurans, across multiple timepoints post-challenge, were analysed. The expression of proteins with established roles in innate immunity, across various timepoints, was compared with expression in naïve Atlantic salmon to elucidate the host response to gill colonisation.

Atlantic salmon gastric mucosa LC-MSMS

Project description:The Atlantic salmon (Salmo salar) genome contains 10 chitinase encoding genes, but little is known about the function of these chitinases. Three of the chitinase genes have previously been shown to be expressed in the stomach tissue of Atlantic salmon. In the current study we show that the protein products of these genes, the family 18 glycoside hydrolase (GH18) chitinases, Chia.3, Chia.4 and Chia.7 are secreted into the stomach mucosa and are amongst the most abundant proteins in this matrix.

Investigation of the host response of naïve Atlantic salmon gill to repeat inoculation with Paramoeba perurans

Project description:In aquaculture, recurrence rates of Amoebic Gill Disease (AGD), caused by the ectoparasite Paramoeba perurans (P. perurans) are high and no prophylactic strategies exist for disease prevention. In this study, Atlantic salmon (Salmo salar) were initially inoculated with P. perurans and following the development of amoebic gill disease were treated with fresh water immersion on day 21 and day 35 post inoculation. Fish were re-inoculated following a negative Q-PCR analysis for the presence of P. perurans. The gill host immune response was investigated at 7, 14 and 18 days post re-inoculation. Differential proteome expression of immune related proteins was assessed by comparison of each time point against naïve controls. In the gill, some proteins of the innate immune system were expressed in response to gill re-colonisation by P. perurans, while no features of adaptive immunity were found to be differentially expressed. Many of the proteins identified are novel in the context of AGD and their expression profiles suggest that their roles in the response to disease development and progression in single or multiple infections warrant further investigation.

The olfactory transcriptome and progression of sexual maturation in homing chum salmon Oncorhynchus keta

Project description:This study aimed at providing insights into the hypothesized functional link between olfactory sensing of the spawning ground and final sexual maturation. We have therefore assessed the presence and expression levels of olfactory genes by RNA sequencing (RNAseq) of the olfactory rosettes in homing chum salmon Oncorhynchus keta Walbaum from the coastal sea to 75 km upstream the rivers at the pre-spawning ground. RNAseq revealed the expression of 75 known and 27 unknown salmonid olfactory genes of which 13 genes were differentially expressed between fish from the pre-spawning area and from the coastal area, suggesting an important role of these genes in homing. Olfactomedins and ependymin are candidates among the differentially expressed genes that may connect olfactory reception to the expression of sgnrh to regulate final maturation. Deep-sequencing transcriptome analysis of twelve chum salmon olfactory rosette RNA samples: three females and three males from the pre-spawning area and three females and three males from the coastal area.

Differential gene expression analysis for California yellowtail (Seriola dorsalis) to investigate slow- and fast-growing larvae over different growth stages

Project description:In this study, we describe the generation of whole larval transcriptomes for the California yellowtail (S. dorsalis) at three developmental stages: two, seven, and seventeen days post hatching (dph) using RNA-Seq on the Illumina HiSeq 2500 sequencing platform. Transcriptional profiles and differential gene expression were also investigated for slow- and fast-growing larvae over these same stages.

The farmed Atlantic salmon (Salmo salar) skin-mucus proteome

Project description:Norway is the largest producer and exporter of farmed Atlantic salmon (Salmo salar) worldwide. Skin disorders correlated with bacterial infections represent an important challenge for fish farmers due to the economic losses caused. Little is known about this topic, thus studying the skin-mucus of Salmo salar and its bacterial community depict a step forward in understanding fish welfare in aquaculture. In this study, we used label free quantitative mass spectrometry to investigate the skin-mucus proteins associated with both Atlantic salmon and bacteria. In addition, the microbial temporal proteome dynamics during 9 days of mucus incubation with sterilized seawater was investigated, in order to evaluate their capacity to utilize mucus components for growth in this environment.
