1 Spawner surveys for the Broughton area
The figures below show the observed number of spawners observed in water-bodies over time. The data originates from the New Salmon Escapement Database (NuSEDS) and was downloaded the 2025/01/03. We filtered the data to only display time series that met the following criteria: (1) at least 15 data points, (2) the most recent data point no older than 2013, and (3) a maximum count of at least 100 fish.
Populations are displayed according to the latitude and longitude of their streams. Numbers in brackets in the top right corner of the time series plots corresponds to the numbers of the survey locations shown in the maps.

2 CUs that have spawner surveys in area 12
2.1 Biological status
The figure below shows the biological status for all the CUs in Area 12. Species-specific maps and status are presented in the following subsections. The numbers in the maps are the CUIDs, the colour of the CUs’ polygons correspond to their biological status. Time series, current spawner abundance and corresponding biological status are only shown for the four pink CUs whose status is assessed.

Below are the estimated spawner abundance (grey line) and rolling average over the generation (black line) for the CUs with an assessed status. The upper and lower benchmarks are represented by the horizontal green and red lines, respectively. Vertical green and red segments on the right show the benchmarks’ 95% credible intervals. The CU’s current spawner abundance is shown by the horizontal segment on the right whose colour corresponds to the CU’s biostatus. The latter was determined with the Hierarchical Bayesian Spawner Recruit Ricker modelling approach (HBSRM) (cf. Technical Report for details). The species, CU name and CUID are displayed in the top of each plot.
