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.

Project description:Fish were fed a standard fish meal (FM) diet or a diet with partial replacement of FM with solvent extracted camelina meal (CM) (8%, 16% or 24% CM inclusion) during a 16-week feeding trial. A significant decrease in growth performance was seen in fish fed the CM inclusion diets. A 44k oligonucleotide array experiment was used to identify any differentially expressed transcripts in the distal intestine of the fish fed the 24% CM diet compared to the control. The expression level of these genes was validated using quantitative polymerase chain reaction, which was also used to measure transcript expression in the fish fed the 8% CM and 16% CM diets. Histopathological analysis was used to quantify any physical signs in inflammation in the distal intestine of the Atlantic salmon fed the CM-containing diets.

Project description:This study was performed to investigate assess the impacts of CO and/or CM containing diets on Atlantic salmon hepatic gene expression in order to identify candidate molecular biomarkers of responses to camelina-containing diets. Atlantic salmon were fed diets with complete or partial replacement of FO and/or FM with camelina oil (CO) and/or camelina meal (CM) in a 16-week trial (Control diet: FO; Test diet: 100% FO replacement with CO, with solvent-extracted FM and inclusion of 10% CM (100COSEFM10CM). A 44K microarray experiment identified liver transcripts that responded to 100COSEFM10CM (associated with reduced growth) compared to FO controls at week 16.

Project description:Black soldier fly larvae meal (BSFL) from Hermetia illucens is a promising alternative protein source in diets for farmed fish. The larvae can efficiently convert low-value organic material into high quality protein in a production cycle with low arable land and freshwater inputs. A few recent studies have shown that BSFL is a suitable protein source for Atlantic salmon (Salmo salar) in smaller controlled experiments. However, industry-relevant field trials conducted under large scale near-commercial conditions over a longer period are lacking. In this study, a feeding trial was performed to evaluate the impact of BSFL on growth performance and health of Atlantic salmon during the grow out phase in seawater, in a commercial site in Vestland county, Norway. A total of 320,000 post-smolt Atlantic salmon were distributed into six duplicate sea cages and fed one of three diets (commercial-like control diet and two test diets partially replacing the protein content of the control diet with 4 % and 8 % defatted BSFL meal) for 21 weeks, until a relevant commercial slaughter size of 4.5-5.0 kg was reached. Health parameters were assessed including histology of the distal intestine (DI), in addition to DI microbiota identification (by 16s rRNA-seq) and salmon RNA-seq of DI and head kidney (HK). The results showed that the inclusion of BSFL meal supported growth performance and had no adverse effect on gut health. The beta diversity of the distal intestine microbiota and the relative abundance of families Lactobacillaceae and the chitinolytic Bacillaceae increased in the fish fed the BSFL diets. Additionally, no histopathological changes were attributable to BSFL meal intake. Results from RNA-seq in DI revealed that BSFL inclusion modulates metabolic processes associated with lipids, the response to estrogens, the activity of immune receptors (to chemokines), phagocytosis and extracellular vesicles. Based on these results, black soldier fly larvae meal is a suitable alternative protein ingredient in inclusions of up to at least 8 % for Atlantic salmon under industrial fish farming conditions.

Project description:The present study aimed to identify the persistent molecular changes occurring in Atlantic Salmon salmon (Salmo salar) eggs after 24h exposure to high concentrations (5000 mg/L) of road salt at fertilization. Atlantic Salmon (Salmo salar) eggs after fertilization were exposed to high concentrations (5000 mg/L) of road salt for 24 h and used for gene expression analysis.

Project description:Atlantic salmon (Salmo salar L.) is an environmentally and economically important organism and its gene content is reasonably well characterized. From a transcriptional standpoint, it is important to characterize the normal changes in gene expression over the course of early development, from fertilization through to the parr stage.S. salar samples were taken at 17 time points from 2 to 89 days post fertilization. Total RNA was extracted and cRNA was synthesized and hybridized to a new 44K oligo salmonid microarray platform. Quantified results were subjected to preliminary data analysis and submitted to NCBI’s Gene Expression Omnibus. Throughout the entire period of development, several thousand genes were found to be differentially regulated. This work represents the trancriptional characterization of a very large geneset that will be extremely valuable in further examination of the transcriptional changes in Atlantic salmon during the first few months of development. The expression profiles can help to annotate salmon genes in addition to being used as references against any number of experimental variables that developing salmonids might be subjected to.
