ESR10 - Field monitoring methods to assess fish pass efficiency

Host Institution: FVT - Fiskevårdsteknik i Sverige AB 

Location: Lund (Sweden)

Doctoral degree: PhD in Biology at Karlstad University.

The Doctoral progamme has a duration of 4 years (3 years funded by RIBES project, 1 year by Karlstad University)

Job description: The project will assess performance of fish pass facilities by the use of state-of-the-art technology allowing for continuous high-resolution monitoring of fish movements at critical passages in fish migration routes. The overall aim of the doctoral project is to improve existing tools for detailed fish monitoring in rivers and to develop methods for data analysis. Field work will be carried out in multiple Swedish rivers to evaluate and compare the efficiency of existing multi-species fish survey methods, including equipment based on an infrared scanning technology with high-resolution cameras. The analysis will exploit the supervisors’ extensive experience of field studies using biotelemetry, i.e. methods to acquire remote or 'difficult-to-collect' biological data from free ranging animals.Research activities include: to contribute to the development and validation of monitoring technology that combines high-resolution cameras and telemetry; to implement fish monitoring system prototype in the field to evaluate the performance of a newly-constructed multi-species fish passage facility; to explore how the physical environment interacts with different phenotypes to shape migration patterns and success of riverine fish species; to use fish counts from multiple sites and years to investigate the importance of abiotic parameters for variation in life-history, for example migration phenology for different species; to compare quantities and qualitative methods for evaluating fish passage solutions to develop standardized protocols for fish passage evaluations.

Workplace: Fiskevårdsteknik i Sverige AB (FVT) offers consulting and contracting services in the field of river restoration. The core business of the company is designing and constructing fish passage solutions and monitoring technology. The ESR will be provided with office spaces both at the new FVT office next to Lund Central Station and at Karlstad University. FVT has extensive experience and modern field equipment for monitoring fish in rivers and has access to data from ongoing monitoring studies. The co-developed VAKI-system for automatic fish monitoring will be further developed and tested at a newly-designed Swedish multi-species fish passage facility. 

Secondment period (to be confirmed): Expected duration: 8 months; Hosting institutions: KAU (Karlstad University - Karlstad, Sweden - 6 months Doctoral training on aquatic ecology and conservation biology to attain the degree), POLITO (Politecnico di Torino - Torino, Italy)

Specific requirements of the Doctoral School:

For admission to doctoral studies applicants must meet the requirements of both general and special eligibility (Higher Education Ordinance, Ch. 7 sect. 35). Applicants who have a Master's degree of at least 240 higher education credits, including at least 60 credits at Master level, or who have acquired largely equivalent knowledge in some other way in Sweden or abroad, meet the general eligibility requirements. To be eligible for admission to graduate studies in Biology requires that one has at least 120 credits in Biology, including a 30 credit independent research course.

Mobility rule:

Applicants must not have resided or carried out their main activity (work, studies, etc.) in Sweden for more than 12 months in the 3 years immediately before the recruitment date. Compulsory national service, short stays such as holidays, and time spent as part of a procedure for obtaining refugee status under the Geneva Convention are not taken into account.
