Bottom-Up – NUI to Facilitate Another Fish Welfare Project

NUI is ready to facilitate yet another groundbreaking research project.

The Bottom-Up project which is formed as a consortium consisting of Aqua Kompetanse AS, SINTEF Ocean, University of Bergen and NUI, and which is financed through FHF, will provide new knowledge about how salmon handle crowding, loading, and transport directly from depth, a prerequisite for further development of deep farming as a production method. Deep farming has the potential to reduce sea lice, improve fish welfare, and enable a more sustainable use of marine and ocean areas, but it also brings new biological and technical challenges.In this project, researchers will examine how pressure changes affect the swim bladder of farmed salmon, what happens when the fish are crowded at depth versus at the surface, and how this in turn influences buoyancy, stress levels, and slaughter quality.

NUI plays a key role.

With our unique expertise in hyperbaric operations, NUI takes responsibility for demanding and critical tasks in the project. We provide pressurization and decompression, advanced testing and operation of pressure chambers, as well as manned diving operations and technical control. These are fields in which we have built up decades of experience, and where we can deliver at a level few others can match. With world-leading facilities and dedicated staff available around the clock, NUI delivers not only technical support, but also safety and quality throughout the entire process. We ensure that the project is carried out efficiently, safely, and to the highest scientific standard. NUI is more than a test and verification center, we are an innovation partner, putting our experience into play where future challenges demand new thinking and precision under extreme conditions.
