One of these species differences is related to the swim bladder, which is open in salmon and closed in cod. The closed swim bladder limits the cod's opportunities for rapid vertical migrations, especially from the depths and upwards in the water column. Technology developed for salmon farming is thus not always suitable for cod farming. Especially in feeding technology, there is a need for more species-adapted solutions, as cod cannot utilize surface feeding efficiently if it is deeper than ten meters. Fjord Marin Cod (FMC) has taken the initiative for this project, with the motivation that they see the need for new technological solutions to streamline their cod farming operations. FMC is trying to scale up to larger cages, but the cod's swim bladder function makes it necessary to limit the cage depth for a good effect of surface feeding with existing technology. Today's equipment for underwater feeding is considered by the company to be inadequate in terms of control, reliability and user-friendliness. The solution to the challenge is to establish a new principle for feeding during the year. The project consortium behind this application has set itself a goal in developing a feeding system with active feeding points, which is controlled so that the feed can be delivered in the cage where it will be most useful. This will be achieved with advanced regulation, based on measurements and model calculations of the environment in the cage and the distribution of biomass. The feed must be distributed in such a way the fish do not have to make an effort to obtain it and it must create the conditions for the fish to be distributed in the cage where it finds the best environmental conditions at any time.
