7,000 years before farming reached Scandinavia, hunter-gatherers carried live trout past waterfalls to stock fishless mountain lakes. Newly dated fish traps at Lake Tesse, Norway show planned ecosystem management long before agriculture. 🐟🏔️🦴 #Archaeology #Mesolithic @antiquity.ac.uk

The Fish That Shouldn’t Have Been There
Every trout in the Norwegian mountains got there because someone carried it.

There's something fishy going on in the frigid, dark depths of Lake Superior. Scientists have discovered a growing number of emaciated lake trout deep in Lake Superior, about half their normal body weight, dubbing them "zombie fish." They’re racing to learn what’s behind the phenomenon.

🐟🌡️🧪 New study from #ThermoEvo project @luke.fi: Juvenile Atlantic salmon show no increase in aerobic scope during an ecologically realistic #heatwave. This suggests limited capacity to cope with higher oxygen demand in warming rivers, when O2 costs increase. onlinelibrary.wiley.com/doi/10.1111/...
Photo by Panu Orell. A juvenile salmon in a river, on top of a red and black rock. There is algae around the rock in the river bottom but the water is very clear. Sunlight is reflected on the fish scales, and showing the red and black dots, and brown, tall stripes on the side of the fish.

When baby salmon emerge from the gravel, how far do they disperse to summer rearing grounds? We haven't known until now (at least at the population scale), because they're too small to tag. In a paper just out, we answered this question using parentage-based (genetic) tagging! tinyurl.com/39b2sfjd

Atlantic #salmon, brown #trout and their hybrids can be difficult to distinguish, especially at early life stages. This new DNA-based method can be used to screen lots of individuals to verify the species or detect hybrids! 🧪🐟 With a low-cost DNA extraction, it is less than 1 euro / sample.
