Researchers identify light-sensing cells in salmon pituitary tied to smolt timing

Discovery explains how salmon read seasons, with aquaculture implications. Researchers led by the University of Massachusetts Amherst report that Atlantic salmon pituitary glands contain photoreceptors that directly sense daylength, triggering hormonal changes linked to seasonal behaviours such as smoltification and migration. The findings, published in Proceedings of the Royal Society B, show that exposing isolated [...]
