About the position 

The Department of biological sciences (IBA), NTNU seeks a highly qualified, ambitious and motivated candidate to aid research on biomass estimation and behavioral monitoring of fish in sea-based aquaculture. The aim is to utilize data from multiple data sources to estimate biometric parameters and to conduct fish behavior profiling. We are looking for a candidate with strong analytical and data handling skills, in combination with good knowledge about fish and aquaculture, especially the rearing of Atlantic salmon. The project will use data from hydro-acoustic sensors, video recordings of fish in and around net pens and environmental variables connected to various aquaculture sites.

To date, the salmon aquaculture industry lacks systems for accurate biomass estimation of salmon in commercial production cages. We also have no system in place to observe and understand farmed salmon distribution and behavior in large scale sea-based production. Accurate knowledge of fish biomass and behavior will aid production decisions and utilization of resources, thereby improving fish welfare and environmental and economical sustainability of salmon production. This position will be part of an effort to develop and implement into commercial production proper analysis of salmon biomass and group behavior of farmed fish.

The position is located at the Department of Biological Sciences Ålesund (IBA), NTNU, and the appointment has a duration of two years. The position is part of the innovation project “Biometric profiling of aquaculture enclosures utilizing hydro-acoustic sensors”, and the candidate will work in close collaboration with the project owner, Furuno Norge AS. The workplace is at NTNU in Ålesund, and it will be possible to spend time Furuno’s offices to aid proper and continuous collaboration. This position is also connected to the InnoSea research group at IBA and our research activities within salmon welfare and behavior.     

The Department of Biological Sciences Ålesund (IBA) is closely linked to the regional industry, both in the health and the marine sector. The department focuses on interdisciplinary research and research-based innovation related to sustainable salmon farming, the marine environment, marine ingredients, and medical and laboratory technology. IBA holds a full-scale farming license for salmonids located at several farming sites in Møre og Romsdal. Further information is available at the department’s homepage:

The postdoctoral fellowship position is a temporary position with a goal to qualify for work in senior academic positions.

The position reports to Head of department.

Duties of the position

This position is central to couple biological competence on fish anatomy and behavior to the technical and data management needed to interpret and use acoustic sensor data from fish in aquaculture. The successful candidate will therefore work in a team with experts in these areas at the interface between NTNU and Furuno Norge AS. The position will also connect the aforementioned innovation project with ongoing activities at the InnoSea research group.

The successful candidate will:

  • plan and conduct field and laboratory work necessary to evolve biomass estimation based on acoustic sensor data. This may include experimental design using fish in commercial production cages and possibly in other experimental cages and setups in the sea
  • plan and conduct field experiments using multi-beam sonar technology to observe, analyze and describe fish behavior in commercial production cages
  • develop biological models necessary for improved behavioral models and biomass estimation
  • work in close collaboration with Furuno Norge AS
  • take a prominent role in the InnoSea research group, combining the aforementioned work with other ongoing activities on fish behavior and welfare, and other topics that may be aided by acoustic measurements, including wild fish aggregations and aquaculture net deformation.
  • disseminate scientific findings according to the project description of the aforementioned innovation project and an associated consortium agreement. Publishing will be done with focus on the use of methods that will be developed in an aquaculture setting.

Required selection criteria

The successful candidate must have completed a Norwegian doctoral degree in a research area relevant to this position, which may include marine biology, aquaculture, biological statistics or other topics in statistics, data science or similar, if applied in relevant biological settings. Alternatively, the successful candidate must hold a corresponding foreign doctoral degree recognized as equivalent to a Norwegian doctoral degree.

The successful candidate also has experience from sea-based production of finfish. Experience with field work and the administration and analysis of large datasets will be highly advantageous for this position.

The appointment is to be made in accordance with the regulations in force concerning State Employees and Civil Servants and national guidelines for appointment as PhD, post doctor and research assistant  

Preferred selection criteria

  • knowledge and interest in applied research
  • keen interest in aquaculture and strong ability to work problem-oriented
  • good analytical skills
  • documented experience within field work, aquaculture, animal behavior, statistics and/or advanced data handling will be an advantage
  • good written and oral Norwegian or English language skills
  • Applicants who do not master a Scandinavian language should provide evidence of good written and oral English language skills. The following tests can be used as documentation: TOEFL, IELTS, Cambridge Certificate in Advanced English (CAE), or Cambridge Certificate of Proficiency in English (CPE). Minimum scores are:
    • TOEFL: 600 (paper-based test), 92 (Internet-based test)
    • IELTS: 6.5, with no section lower than 5.5 (only Academic IELTS test accepted)
    • CAE/CPE: grade B or A.

Personal characteristics

  • self-motivated, enthusiastic and creative
  • strong collaborative skills
  • ability to work independent and goal-oriented
  • interest in multidisciplinary, complex problem solving in interdisciplinary teams
  • ability and willingness to conduct fieldwork at sea

In the evaluation, emphasis will be placed on education, experience and personal suitability, as well as motivation, in terms of the qualification requirements specified in the advertisement
