On Thursday 23 August Steve Railsback from Humboldt State University, California USA, will give a seminar at Karlstad University titled: ”Can Big Complex Models be Useful? Lessons from 20 Years of Salmonid Modeling for River Management”.

The seminar will start at 10:00 in room 5F416, everyone is welcome to attend the seminar.

Steve will give a brief overview and history of individual-based trout and salmon models, and provide examples of how the modeling experience produced general knowledge about ecology and fish.

During the spring semester the master’s course Scientific methods in freshwater ecology is given at Karlstad University. The course is held by researchers from the NRRV research group, and is included in the master program in ecology and conservation biology at Karlstad University. The course is available for distance students, and most students on the course live in other places in Sweden than Karlstad. We also have international students on the course, this year from both Europe, North America and Africa. In 2018, some parts of the course were carried out together with a visiting student group from Northern Kentucky University.

Here follows a report of the field and laboratory work carried out by the students on the course in 2018.

The first practical session started Monday 24 April, and focused on fish tagging and laboratory studies. The week started with Professor Erik Petersson from the Swedish University of Agricultural Sciences (SLU) having a lecture on ethics and legislation concerning animal experimentation. Thereafter the students had practical training in fish handling and sedation. The following days were spent at the laboratory facilities at Karlstad University, where students practiced different methods for tagging fish. The students also conducted experiments in the stream aquarium laboratory, where they examined how the drift-feeding behavior of juvenile brown trout changed in the presence of a predatory fish. This gave the students an opportunity to plan and conduct a laboratory study from the beginning to the end.

After the laboratory session in Karlstad, the week continued in Mörrum in southeastern Sweden. The course was given a tour of the area and shown remedial measures to facilitate fish migration in the regulated river Mörrumsån. In addition, the students conducted a field study where they looked at downstream migration of Atlantic salmon.

A month later, a second course gathering was held in Karlstad, this time focusing on benthic invertebrate sampling and electrofishing. This course module was carried out together with a visiting student group from Northern Kentucky University. The first day was spent at river Rannån, where students learned different methods to measure abiotic conditions in running waters and how to sample benthic fauna. The second day was spent at river Djupedalsbäcken where the students practiced electrofishing, which resulted in that all students on the course became certified electrofishers. Electrofishing is the most common method used for monitoring fish populations in streams. Therefore, it is a valuable skill for people interested in pursuing a career in stream fish ecology.

A crowdfunding platform has been initiated for dam removal projects across Europe, the site being hosted by WWF Netherlands.

In the past, thousands of dams have been used for hydropower throughout Europe. Many of these dams are not used anymore, and instead create barriers for migrating species and thus inhibit ecosystem connectivity. This affects both migrating fish that cannot reach their spawning and feeding grounds, but also other animals that depend on the fish, such as fish-eating birds and mammals. The aim with the Dam Removal Crowdfunding Platform is to raise financial support to remove old dams in Europe that currently are not in use, so that flee-flowing river ecosystems can be restored.

Karlstad University, Hudiksvall municipality, the county board in Gävleborg and Dam Removal Europe are arranging an international seminar on dam removal in Hudiksvall, Sweden, 24-26 September 2018. The aim of Dam Removal Europe is to restore European rivers by removing dams, and in that way ensure the preservation of free-flowing rivers full of fish.

Several different aspects of dam removal will be discussed during the three-day seminar, such as effects of dams on migratory fish and whole ecosystems, social issues, hydro-industry perspectives and existing policies. The seminar will also include presentations of case studies and a visit to dam removal sites.

In April 2018, Anissa Bengattat from France visited Karlstad University and did an internship with NRRV. Here she writes about her weeks in Sweden.

Hej där!

I’m Anissa Bengattat, a French student in HND ‘Management and Protection of Nature’ in a town located in France, named Vic-en-Bigorre. As a practical training, I have been doing my three-weeks internship at Karlstad University with the Ecology and Conservation Biology program.           

During these weeks, I have learned vastly about different aspects of  freshwater ecology.  My main mission has been to collect, sort, identify and archive macro-invertebrates, collected in the field, in the freshwater stream Rannån. With the help of Richard Durtsche, guest-professor from the USA, and his student Rachel Prokopius, I managed to follow a project from the start to the end.

I have tested digital imaging of the identified invertebrates, and I have seen the calorimetry process, used in order to make links with the fishes‘ energetics consumption.

 I have also been in the stream aquarium laboratory to participate in some interesting experiments. First, I have learned about the whole fishes respirometry system, made up by R. Durtsche, where we studied oxygen consumption for brown trout. Then, I’ve learned about Karl Filipsson’s experiments about climate change effects on predation on brown trout. Their behaviour, linked to the temperature and the presence or not of burbot, and how to identify it scientifically by extracting trouts‘ RNA.

 Finally, I have attended master classes for these three last weeks, which consolidated my idea to do a bachelor after my HND, and then a master, if possible, abroad.

This internship wasn’t only about studies to me, it was also about meeting new people in another country with a different way of living, and a different way of teaching. It was about making concrete links in my mind between how much I still have to learn, and how to develop into an accomplished scientist.

Thanks to John Piccolo who set up my internship, thanks to the international office of Karlstad university which helped, and thanks to Elio Bottagisio, the French master student who told me about this program. And finally, thanks to all the people who taught me things during this internship,  Richard Durtsche, Rachel Prokopius, Olle Calles, and Karl Filipsson. I hope to come back.
