We investigated the effect of a fishway on the genetic structure of brown trout populations, finding that the fishway *increased* genetic structuring, we think because it enabled fish to move to their preferred spawning sites.

Diversity in the internal functional feeding elements of sympatric morphs of Arctic charr (Salvelinus alpinus)
4 sympatric morphs
Variation in adult size, age and morphology...and their head bones.

This is quite the salmon! 'O. rastrosus fossils have been found along the US west coast and Japan. It swam the North Pacific during the late Miocene (23–5.3 million years ago) and early Pliocene (5.3–2.6 million years ago).' https://cosmosmagazine.com/history/palaeontology/largest-salmon-tusk-teeth/ #foodhistory #salmonids

Fieldwork w great graduate students

More photos of the repaired BDA instream stuctures on Lost River, tributary of the Mattole river. They held up well to extremely high flows last winter. These are permeable dams that mimic beaver dams. This is a Sanctuary Forest Project within the Mattole Watershed, to enhance summer stream flows in the Mattole river, and salmonid habitat enhancement

Time for a short #introduction I guess. I'm Clémence Fraslin, core scientist at the Roslin Institute in Scotland 🏴. I'm a quantitative geneticist in Aquaculture, with a main interest in disease resistance and sustainability. I study genetic architecture of traits and genomic selection mainly in #salmonids.
I love talking about food 🧀, baking 🥧, reading, my house plants and cats, especially the one that lives with me (or maybe I live with him?) Here's a picture of Le Chat👇
