Byskeälvens Övre FVO - Fångstrapporter

This dashboard covers the upper Byskeälven fishery — the Norrbotten (Arvidsjaur) section above Fällfors, up to the river’s source at Lake Kilver. Reports are submitted voluntarily by licensed anglers through ifiske.se and logged both as caught fish and as unsuccessful trips ("Ingen fisk").

Compared with the Västerbotten lower section, this is a markedly different fishery: smaller numbers, quieter beats, and — most importantly — a species mix that tilts heavily toward grayling rather than salmon. The charts below cover the 2023, 2024 and 2025 seasons, the three full years since ifiske reporting was rolled out on the upper river.

The upper-river season starts later than the lower beats — the first meaningful activity shows up in June once water warms and drops after snowmelt. July is the busiest month with 273 reports, followed closely by August at 229. By early September the season is winding down and reports taper off quickly.

Catch rate on the upper section runs around 40 % of reports — notably higher than the lower river, because grayling are both more numerous and easier to catch on light tackle than a migrating salmon. Unlike the Västerbotten beats, the upper FVO does not track fishing method or fish length in its reporting, so the dashboard focuses on species mix and seasonal timing rather than method breakdown or size histograms.

Harr — Grayling (242 reports) is the headline species of the upper river and accounts for roughly one in every three reports. Minimum size is 35 cm and the daily limit is five fish. Abborre — Perch (66) and Öring — Brown trout (31) are the next most common; perch come from slower side-waters, brown trout from the main current. Gädda — Pike (27) show up occasionally in the slower reaches, while Lax — Atlantic salmon (14) are rare this far upstream — most don’t push above Fällfors in meaningful numbers. Single-digit reports include Id — Ide (3) and Röding — Arctic char (1).

The upper FVO does not collect fishing method or catch length in its ifiske reporting template, so those dimensions are blank in the raw data and the corresponding widgets (method breakdown, size histogram) are intentionally suppressed. Zone-level breakdown is also unavailable — the upper section is reported as a single unit. The dataset starts in June 2023 when ifiske reporting went live for this FVO; earlier years are not represented here.
