The project deals with wild-caught cod and getting used to feed in farming. The significance of the fish's damage status at reception has been evaluated, and operational sorting criteria have been proposed. Only moderate injuries are considered acceptable; no open wounds, only a small degree of fin erosion, if the fish is to be able to heal the damage within a reasonable time. Fish that are considered to be of good quality and suitable for feeding show considerable variation in appetite. About 20% of cod did not eat in captivity, even when offered natural (but dead) prey. Attempts to accustom the cod to formulated feed showed that as many as 60% would not eat in captivity. The fish that ate grew in accordance with expectations based on table growth in farmed cod. The proportion who started eating did not differ from other fish, either in terms of size or fitness factor, and sorting the fish on the basis of size did not contribute to improved results during habituation to capelin. Mechanical sorting of fish that eat from fish that do not eat can be a more precise and faster method of sorting. Several alternative solutions have been outlined and evaluated, and it is probable that mechanical sorting of the fish is within reach.
The goals of the project are:
• To find sorting criteria and limits for damages that can affect welfare and finances during the weaning period.
• To clarify any connections between the fish's size and growth during feeding.
• To improve the fish's motivation to eat formulated feed.
• To develop a behaviour-based method to identify fish with motivation to eat.
• To acquire biological and technological knowledge for application to the development of a functional sorting system for wild-caught cod."
