Inferring activity patterns of aquatic animals from single‐receiver acoustic telemetry setups

Acoustic telemetry has become an essential tool for studying activity patterns of animals in aquatic environments. Activity is typically recorded using transmitters with integrated sensors or dens...

Over 400 juvenile #lampreys were #PIT tagged to unravel their oceanic life stage. Tagging campaigns in the #Mondego River conducted by DiadSea researchers from @cienciasulisboa and @UEvora continue, with the first results expected in Spring 2026! @AtlanticArea @MAREscience

Good to see this paper finally out: doi.org/10.1186/s40317-024-0… Great baseline data on depth use of migrating salmon smolts in fjords! Key takeaway: smolts predominately migrate in the top 3 meters of the water column throughout the fjord.

Depth use of wild Atlantic salmon post-smolts migrating through fjords

Animal Biotelemetry - Juvenile Atlantic salmon (Salmo salar), known as post-smolt as they enter the sea, undergo an arduous migration from their natal rivers to their feeding grounds in the North...

Atlantic salmon Salmo salar typically enter fresh water several months prior to spawning and just as pools can provide areas of refuge in river systems, lakes may also provide important refuge...

New from @sceneUofG - navigation in downstream migrating salmon smolts switches from rheotaxis in rivers to a random search tactic in lakes except where residual flow cues in some lakes prevent this, at times resulting in suboptimal navigation outcomes.  doi.org/10.1111/jfb.15972

Lake shape and the characteristics of migration behavior modify Atlantic salmon smolt migration...

Migration is a high-risk behavior. For the Atlantic salmon, Salmo salar, migrating from its river nursery area to marine feeding grounds, the magnitude of risk varies with habitat type. Passage...

High migration success of Atlantic salmon smolts in standing waters could be due to relative current speeds providing good quality directional cues to migrants. More from @JessicaRFordyce @C_Adams1758 @AngusJLothian @sceneUofG @UofGSBOHVM @Galloway_FT  doi.org/10.1111/eff.12821

Riverine habitat fragmentation by barriers, including impoundments, is common and their effects on obligate aquatic organisms are manifold. Organisms, such as Atlantic salmon (Salmo salar), that...

When Illinois Waterway locks closed in 2020, a busy riverine shipping corridor ground to a halt. The river responded. The vessel traffic pause led to improved water quality and a redistribution of fishes. Read about it in our OA @STOTEN_journal article from @INHSillinois @USGS

One of the largest spawning migrations of Zander in lake Vänern (Sweden’s largest lake) happens in the river Byälven. Where do they go? How long are they in the river? Trying to answer these questions and more for management with acoustic telemetry. @Lst_Varmland @OlleCalles
