WFD classification · PLRW200010472689
Polish PZW national rule: grayling (lipień) protected 1 March – 31 May. Open window 1 June – 28 February. PZW district and water-specific rules may add tighter restrictions. Carpathian rivers (San, Dunajec, Biała, Skawa, Raba) hold excellent grayling — check local Okręg PZW district permit for specific conditions.
Closed in spring for spawning.
Prime sport 1 September → 30 November
National pike protection period is 1 January–30 April. No district-specific override was found for this river in the available PZW Słupsk documents, but a river-name-specific line item wasn't directly confirmed either — treating the national baseline as the working default.
Sea trout: Variable seasonal (2026)
