| Individual stress coping style (reactive, intermediate and proactive) was determined in 3 groups of 120 pit tagged European seabass using the hypoxia avoidance test. The same three groups (no change in social composition) were then reared according to the standards recommended for this species. Then, 127 days later, individuals initially characterized as reactive, intermediate or proactive were submitted to an acute confinement stress for 30 min. Blood samples were taken to measure plasma cortisol levels 30 min (Stress30) or 150 min (Stress150) after the end of the confinement stress. Individuals were then sacrificed to sample the telencephalon in order to measure the main monoamines and their catabolites (at Stress30 only). Individuals from Stress150 were... |

| The aim of Robustfish project is to answer the following research questions: (1) Is it possible to select robust rainbow trout fry early in development before they enter the more cost intensive steps in the production cycle? (2) Does sustainable (non-fish based) dietary lipid sources affect stress resilience and immune-competence of the fry? (3) Related to (1) and (2): Is improved resistance to RTFS achieved? (4) How will the market respond to a significant increase in production of organic trout, i.e. consumer preferences and competiveness by companies in the value chain? RobustFish will strengthen the development of Danish organic trout production. In this respect the robustness of the fry to diseases is crucial, i.a. RTFS. The robustness of the fry... |
