Johan Watz (Associate Professor at University of Karlstad Biology Department) together with others from the department, DHI Sverige and Fortum Sverige have recently published an article with VATTEN- Journal of Water Management and Research. The article, entitled ” HOW MUCH WATER DO SEA TROUT NEED? A COMPARISON BETWEEN A CORRELATIVE AND AN INDIVIDUAL-BASED MODEL TO PREDICT EFFECTS OF FLOW ON STREAM FISH POPULATIONS” used both a correlative model and an individual-based fish habitat model called InSTREM 7 as a management tool to assess water requirements for salmon and trout in a river reach located below Blanka-ström hydropower plant in river Emån, Sweden.

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.

Tomorrow, December 15, Åsa Enefalk, PhD Student at Karlstad University, will give a seminar titled ”Fine wood and burbot – do they affect trout sheltering at low water temperatures?”

The seminar will be given at 13:15 in room 5F416 on Karlstad University. Everyone is welcome to attend!
