Project description:Single cell proteins, such as Candida utilis, are known to have immunomodulating effects in the distal intestine (DI) of Atlantic salmon, whereas soybean meal (SBM) can cause soybean meal induce enteritis (SBMIE). Inflammatory or immunomodulatory stimuli at the local level in the intestine may alter the plasma protein profile of Atlantic salmon. These changes can be helpful tools in diagnosis for fish diseases and indicators for fish health. The present work aimed to identify local intestinal tissue responses and changes in plasma protein profiles of Atlantic salmon fed C. utilis yeast, SBM, or combined diets. Fish meal (FM) based diet was used as a control diet and the six experimental diets were: FM diet with 200 g/kg C. utilis (FM200CU) and five diets containing 200 g/kg SBM together with 0 (SBM group), 25, 50, 100 or 200 g/kg C. utilis (SBM25CU, SBM50CU, SBM100CU and SBM200CU groups, respectively). Intestine morphology of fish fed FM200CU where not affected whereas SBM group presented changes characteristic of SBMIE. Low inclusion of C. utilis in SBM diet showed a modulation of immune cell populations, but did not alleviate inflammatory symptom.

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:In this experiment, we used four diets, one based on FM, a challenging diet with 40% soybean meal (SBM), and two diets containing 40% SBM with 5% of Cyberlindnera jadinii yeast exposed to different down-stream processing conditions (heat-inactivated or autolysation). The immunomodulatory effects of the diets were analyzed in the spleen of Atlantic salmon after 37 days of feeding. The results showed that the inclusion of autolysed C. jadinii (ACJ) was able to modulate the response of Atlantic salmon compared to fish fed the SBM-diet, through the activation of biological pathways related to endocytosis, PPRs-signal transduction and transporter activity. Finally, we suggest that the spleen is a good candidate to characterize the immunomodulatory effects of functional ingredients in Atlantic salmon.

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. Atlantic salmon were fed for 16 weeks with the FO or 100COSEFM10CM diet (three tanks per diet). Liver samples were taken from 7 fish from each tank at week 16. A universal reference design was used for the microarray experiment. For the test samples, RNA was used from individual livers of fish from the 2 treatment groups: FO and 100COSEFM10CM. For each treatment group we used 9 biological replicates (3 fish from each of 3 tanks). All test samples were labeled with Cy5. The common reference was a pool of 18 RNA samples from livers of fish from all individuals invovled in microarray experiment. The common reference was labeled with Cy3. Each individual test sample was hybridized together with the common reference sample on an array, so the experiment consisted of 18 arrays

Project description:The objective of the current study was to examine the effects of yeasts on intestinal health and transcriptomic profile of Atlantic salmon fed SBM-based diets in seawater. Cyberlindnera jadinii (CJ) and Wickerhamomyces anomalus (WA) yeasts were produced in-house and processed by direct heat-inactivation with spray-drying (ICJ and IWA) or autolyzed at 50 ºC for 16 h (ACJ and AWA), followed by spray-drying. Six diets were formulated, one based on fishmeal (FM), a challenging diet with 30% soybean meal (SBM) and four other diets containing 30% SBM and 10% of each of the four yeast fractions (i.e., ICJ, ACJ, IWA and AWA). The results showed that the inclusion of CJ yeasts reduced loss of supranuclear vacuolization, along with reduction in population of CD8α positive cells present in the lamina propria of fish fed the SBM diet. The CJ yeasts controlled the inflammatory profile of fish fed SBM through up-regulation of pathways related to wound healing and taurine metabolism. Additionally, the WA yeasts dampened the inflammatory profile of fish fed SBM through down-regulation of pathways related to toll-like receptor signaling, C-lectin receptor, cytokine receptor and signal transduction. The results suggest that yeasts could be used as protein ingredients with functional properties in diets for Atlantic salmon.

Project description:The present study was conducted to investigate the effect of graded levels of black soldier fly larvae (BSFL) (Hermetia illucens) meal and BSFL paste in extruded diets for Atlantic salmon (Salmo salar). A total of 1260 Atlantic salmon with 34 g of mean initial weight were randomly distributed into 21 fiberglass tanks and fed (n=3) with seven extruded isolipidic and isonitrogenous diets for seven weeks. The experimental diets consisted of a positive control diet based on fishmeal, soy protein concentrate, corn gluten, faba bean and fish oil (Control_1); three diets with increased levels of full lipid BSFL meal, substituting 6.25% (6.25_IM), 12.5% (12.5_IM) and 25% (25_IM) of the protein content of Control_1; two diets with increased levels of full lipid BSFL paste, substituting 3.7% (3.7_IP) and 6.7% (6.7_IP); and of protein from Control_1 and a negative a control with 0.84 % of formic acid (Control_2). We investigate the effect of diets on growth performance, mmune response and health.
