High Levels of Straying in Returning, Repeat‐Spawning Atlantic Salmon Between Two Neighbouring Danish Rivers

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
We studied the seaward and return migration of Atlantic salmon kelts from both wild and hatchery origin in River Skjern, Denmark. Of the 199 tagged animals, 110 reached the ocean (55%). Only 10 kelts were recorded returning after spending more than 1 year at sea.

Ulva lactuca Extract in Confectionery Systems: A Sustainable Approach to Natural Pigmentation, Antioxidant Enrichment, and Sensory Optimization in Fondant and Meringue Matrices

open access: yesFood Science &Nutrition, Volume 14, Issue 7, July 2026.
This study evaluated the functional potential of Ulva lactuca extract as a natural colorant and antioxidant incorporated into sugar‐based (fondant) and aerated (meringue) confectionery matrices. Extract incorporation significantly enriched total phenolic content—achieving up to 150.95 mg GAE/100 g dry matter in meringues—and surged antioxidant ...
