On Friday, 21 September, Stan Gregory from Oregon State University will give a seminar titled ”Population dynamics of coastal cutthroat trout and Pacific giant salamanders in old-growth forest and second-growth forest reaches of a Cascade Mountain stream in Oregon, USA”. The seminar will be given at 15:00 in room 5F416 at Karlstad University.

Stan Gregory is in Karlstad as the opponent at Åsa Enfalks PhD defense. Åsa Enefalk will defend her thesis ”Fine stream wood – Effects on drift and brown trout (Salmo trutta) growth and behavior”  at 10:15 on the same day (Friday 21 September) in Nyquistsalen (room 9C 203) at Karlstad Univeristy.

Everyone is welcome to attend both events!


On Tuesdag, 20 September, David Aldvén from the University of Gothenburg, was to give a seminar titled ”Downstream migration of anadromous brown trout”. David Aldvén recently finished his PhD with a thesis titled ”Migration in anadromous brown trout”. The frame of his thesis is available online here.

The seminar has been CANCELED.

Larry Greenberg and Eva Bergman, researchers at NRRV, would like to promote American Institute of Fisheries Research Biologists (AIFRB). The American Institute of Fishery Research Biologists is ”an organization established to advance excellence in fishery science and to promote stewardship, sustainability and wise utilization of natural resources, through support in professional development and recognition of competent achievement of its members, as measured by the highest of professional standards.” Check out the institute’s homepage here.


Greenberg and Bergman last week also attended the 146th Annual Meeting of the American Fisheries Society in Kansas City, USA. They report on many interesting presentations and inspiring discussion. We program can be read here.

Imorgon, tisdagen den 23 Augusti, kommer Åsa Enefalk, doktorand vid Karlstads Universitet, ge ett seminarium med titeln ”Fine stream wood – effects on drift and brown trout (Salmo trutta) growth and behaviour”. Seminariet ges klockan 13:30 i sal 5F416 på Karlstads universitet. Alla är välkomna!

The symposium ”Biology and Ecology of Pike” will be held at Lunds University, Sweden on October 11. The symposium is open to anyone, is free to attend but seats are limited and registration is required. Register to anders.nilsson@biol.lu.se by September 30.


Typically three spined sticklebacks have several spines in their dorsal and pelvic fins. In the ocean, the spines are important for predator defense in an environment with many large predators and few places to hide. For some landlocked populations the predation pressure can be lower or different (large predator fish may be lacking) and the spines may carry a cost instead of offering protection. In fact, several freshwater populations of sticklebacks in Europe and North America lack the pelvic spines – the result of evolution in a different environment. In the short film Making of the Fittest: Evolution of the Stickleback FishHHMI BioInteractive tells the story of the stickleback evolution and interviews researchers that track the genetic mechanism behind the change. Watch the film here.

The international river restoration conference “Restoring floodplains, habitats and connectivity using mussels and brains” will be held in Lund, Sweden, on 28–30 September, 2016. The organizers write: ”Conference objectives are to highlight experiences and results gained from a wide range of river restoration projects focusing on rehabilitation of species of freshwater mussels and fish. Mussels and fish are often used as indicators and flagship species while restoring rivers. But are they any good? If so – why? The first two days will focus on presentations by invited experts and conference participants who want to present their work. The third day includes field visits to Fyleån Creek, Klingavälsån River, both sites re-meandered, and the Hemmestorp Mölla rearing facility. We look forward to seeing you in Lund!”

Last week, Theodore Castro-Santos from Conte Anadromous Fish Research Center (USGS) gave a webinar titled ”Safe, Timely, and Effective: toward a unified metric of passage performance” on the World Fish Migration Platform. The webinar was also streamed live at the Congress of the Iberian Society of Ichthyology, The webinar is now available online (after free registration) at the World Fish Migration Platform here (follow the link at the bottom of the page).
