One of the reasons for this loss is that many smolts have not undergone ""optimal smolt development"", and are therefore not well adapted to life in the sea with a higher salt concentration and exposure to new pathogens. A solution to this challenge is to achieve a more uniform smoltification process, so that as many as possible of the salmon have achieved good smolt status when life in the sea begins.
This project therefore wants to obtain new knowledge about two important factors that can influence smolt development:
1) Are light protocols that simulate changes in day length important for synchronizing the smoltification process?
2) Can the genetic variation in the fish's response to smoltification regimes be used to breed fish with a more synchronous response to different smoltification regimes?
Main goal:
To make it possible for smolt producers in the future to produce a physiologically uniform and seawater-ready population of smolt, and that this should contribute to increasing animal welfare, growth and survival in the seawater phase.
Sub-goals:
• To develop methods for fast and objective measurements of important phenotypes (size, skin health, skin colour, etc.).
• To measure the effects of different light treatments on smoltification development, both at the morphological and molecular level.
• To identify genetic variation linked to variation in smolt development under different light treatments that can be used for breeding for more uniform smolt development.
• To develop new and more precise molecular markers for smolt development that smolt producers can use to monitor smolt production.
