F I G U R E 5 in Migration patterns and navigation cues of Atlantic salmon post-smolts migrating from 12 rivers through the coastal zones around the Irish Sea

F I G U R E 5 Rose diagrams depicting (a) the hour of the day and (b) the direction of currents () when Atlantic salmon (Salmo salar) post-smolts were initially detected at a unique acoustic receiver on monitoring line B. The green and blue arrows show the mean hour (a) and mean current direction (b) when post-smolts were initially detected respectively (Lilly et al., 2022). The orange and yellow bands (a) show the variation in sunrise and sunset times for the total period over which any post-smolts were detected on monitoring line B (ie. April 21st–June 20th).

F I G U R E 4 in Migration patterns and navigation cues of Atlantic salmon post-smolts migrating from 12 rivers through the coastal zones around the Irish Sea

F I G U R E 4 Heatmaps displaying the number of Atlantic salmon (Salmo salar) post-smolts detected at each acoustic receiver on monitoring lines A and B (Figure 1) during the period of this study. The black stars show the location of each river (n = 11) where Atlantic salmon post-smolts originated. Rivers are grouped by coastal region where they entered the Irish Sea (Figure 1, (a) Region 1: Rivers Derwent, Nith, Bladnoch; (b) Region 2: Rivers Endrick, Gryffe; (c) Region 3: Rivers Bann, Bush, Carey, Glendun; (d) Region 4: Rivers Roe, Faughan).

F I G U R E 2 A in Migration patterns and navigation cues of Atlantic salmon post-smolts migrating from 12 rivers through the coastal zones around the Irish Sea

F I G U R E 2 A boxplot plot displaying the dates (mm-dd) when Atlantic salmon (Salmo salar) post-smolts (n = 582) were last detected in their natal river/estuary (Rivers Endrick, Gryffe, Roe, Faughan) or coastal embayment (River Burrishoole) and entered the coastal zones of the Irish Sea or the west coast of Ireland (River Burrishoole; Figure 1: Clew Bay) and were detected on monitoring lines A and B (excluding the River Burrishoole Figure 1). In the boxplots, the centre line represents the median, the box encompasses the 25 to 75% quartiles, the bars are the values within 1.5 interquartile units and the dots represent outliers. It should be noted that the dates when smolts were tagged (represented by the dashed black line) differed in each river system. The thick black lines divide rivers into their coastal regions (see methods).

F I G U R E 1 Map displaying the 14 in Migration patterns and navigation cues of Atlantic salmon post-smolts migrating from 12 rivers through the coastal zones around the Irish Sea

F I G U R E 1 Map displaying the 14 capture sites in 12 rivers where Atlantic salmon smolts (n = 1008) were captured for tagging in England, Scotland, Northern Ireland and the Republic of Ireland for this study. In addition, 60 hatchery origin smolts were tagged and released in the River Burrishoole. The coastal region each river belongs to is referenced in brackets next to the river name. Where Region one (1) refers to the Solway Firth (Rivers Derwent, Nith, Bladnoch); Region two (2) refers to the Clyde Estuary (Rivers Endrick and Gryffe); Region three (3) refers to the Bush Coastal region (rivers Bann, Bush, Carey and Glendun); Region four (4), refers to Lough Foyle (rivers Roe and Faughan); Region five (5), refers to Clew Bay (River Burrishoole). Tagged fish release sites are represented by stars, and acoustic receivers (n = 183) are represented by gray dots. Marine monitoring lines (A and B) in the Irish Sea are labeled in alphabetical order from south to north. Twenty-two acoustic receivers were initially deployed at monitoring line A. One hundred and eight acoustic receivers were deployed at monitoring line B and are labeled in numerical order from the furthest west receiver (R1) on the monitoring line to the furthest east (R108). Refer to Figure S2 for the locations of acoustic receivers that were not retrieved from marine monitoring line A (n = 2) and B (n = 9).

F I G U R E 3 in Migration patterns and navigation cues of Atlantic salmon post-smolts migrating from 12 rivers through the coastal zones around the Irish Sea

F I G U R E 3 The binomial General Linear Model (GLM) model showing the effect of minimum migration distance (Distance [km]) from the exit of smolts natal river/estuary to monitoring line B on the probability of migration success (measured as minimum migration success) of Atlantic salmon (Salmo salar) post-smolt through the Irish Sea. The shaded region is the 95% confidence interval of the final model.

Quantifying the diets of a non-native and native predator during juvenile salmon out-migrations in the Columbia River

This is the clean and raw data files needed to replicate the analysis for our paper. The data contains carbon and nitrogen stable isotope data from several species of fish collected in the upper John Day Reservoir in Washington State in 2012. The data contains stable isotope signatures from predatory Walleye and Northern Pikeminnow, as well as potential prey species. A spreadsheet with descriptions of the column names is included.  All of the code and analysis can be found at Karl Veggerby's Github: https://github.com/veggerk/Columbia-River-predatory-fish-study

Results from a National Survey of Canadian Perspectives on Predicting River Channel Migration and River Bank Erosion

This dataset contains findings from a national survey of Canadian perspectives on predicting river channel migration and river bank erosion. The online survey was conducted by researchers from the University of Guelph from November 2, 2021 through January 31, 2022 and received more than 40 responses from regions across Canada.
