Biography Karsten Heia
I am employed as a senior scientist at the department Seafood industry. I am the main responsible for activities related to instrumental assessment of quality attributes in fish and seafood products. The goal for our research and development activities are to develop solutions that increase value creation in the Norwegian seafood industry. Therefore, it is important for us to have a close relation to the industry to insure that our research are relevant for the industry and eventually the consumers. We have worked closely with the industry for several years and the latest innovation was launched in November 2020.The the Maritech Fish Scanner was launched. This device can based on measuring light, hyperspectral imaging, sort round fish according to species and presence of blood in the white tissue. This represents a revolution for the industry and could not have been developed without the active participation of both research, technology providers and the fish processing industry.This technology now provides a good starting point for development of new solutions based on light measurements that can increase the profitability of the Norwegian seafood industry.
Besides spectroscopy, traditional and imaging, we also work with technologies as magnetic resonance imaging, fluorescence, 3D-imaging and simple imaging setups. Together with the competence on the use of machine learning, multi variate analysis, image processing and so on we are in the position to develop new solutions for future fish processing industry.

1. January 2020 – 20. December 2022
During this project, we will be identifying how the use of various types of commercial fishing gear affect the physiology and mortality of cod and thus their welfare and quality. We will also be investigating the links between ethical fishing, quality and price.
1. May 2018 – 31. October 2019
The purpose of this project is to make a commersial solution for measuring blood in whitefish prior to filleting.
9. February 2017 – 31. December 2022
Over almost 40 years, Nofima has built up a strong scientific community in the field of spectroscopy - rapid and non-destructive measurements for process optimization. We possess solid expertise within an international format and a modern instrument platform, which is unique in Norway and comparable to the best in Europe. We wish to develop this further by means of establishing the strategic research initiative Spectec.
1. March 2015 – 28. February 2019
In this multi-disciplinary project we have studied the entire value chain for mackerel and farmed salmon.
Quality measurement of fresh fish
1. November 2014 – 31. December 2016
The purpose of the project is to develop instruments and mathematical methods for automatic quality control of whitefish and salmon.
1. April 2011 – 30. March 2019
The goal of the centre was a paradigm shift within fisheries technology.
