In intensive farming of Atlantic salmon, feed costs amount to 40-50%. It is thus important to ensure good control of all feed use by maximizing the fish's feed intake and growth; the feed conversion efficiency, while at the same time minimizing feed waste to the environment surrounding the aquaculture plants. In traditional feeding control, an operator of the facility controls all feeding based on visual observations of the fish using an underwater camera. At such plants, it is not uncommon to operate with a feed conversion efficiency between 1.1 and 1.4. This means that there is an excess feeding of almost 30% compared to what is possible if all the food is eaten and feeding protocols are optimised. Such a situation is very costly for the industry and importantly, not very environmentally friendly. In this project, NoFood2Waste, we aim to develop a novel method for optimized feeding control by combining hydroacoustic sensors that register fish's vertical and horizontal movements in the cage with new research-based knowledge about physiology, feeding behaviour and shoal structure in salmon in relation to size and condition through different seasons. We aim to combine knowledge of the fish's physiology and growth capacity at different stages and environmental conditions with appetite-controlled feeding, ie feed the fish when it seeks a defined feeding area and is hungry and stop when it is satiated and pulls away from this feeding area. Based on this, we will develop a new and innovative technical solution for optimized dynamic feeding control in sea-based farming based on real-time monitoring of the salmon's vertical and horizontal behaviour patterns via hydroacoustic sensors. This system should be good for the fish, profitable for the fish farmer and important for the environmental impact.
