Ośrodek Zarybieniowy "Czarci Jar"

Commercial/paid fishery confirmed: it is the PZW-affiliated salmonid fish-breeding center "Ośrodek Zarybieniowy Czarci Jar" (director Rafał Chwalczuk since 1991) that also runs "łowiska specjalne" (special/commercial fishing grounds = 3 ponds) in the upper Drwęca valley, ~500 m W of Drwęck and ~10 km from Olsztynek. Commercial model: entry is free, you pay only for fish you catch (pay-per-catch), hence tryb=z_zabieraniem. Coordinates from the znajdzlowisko listing (53.5544779, 20.167282); the Encyklopedia Warmii i Mazur gives the village point as 53.554988, 20.167436 (consistent). water_type set to "kompleks" because the venue is a complex of ponds (znajdzlowisko: "three ponds"; the breeding center has ~30 ponds total, but only the special grounds are for anglers). PRICING: no published price list found anywhere — znajdzlowisko states "Aby poznać aktualny cennik, skontaktuj się z Łowiskiem" (contact for current prices), so pricing rows left empty. GOOGLE RATING: could not be retrieved — Google Maps requires consent/JS rendering and no rating/review-count appears in any indexed snippet; the Cylex business profile has been removed; google_rating and google_review_count left null. AMENITIES: mapped from sources — rod/equipment rental (wypozyczalnia_lodek used as the closest 'rental' code; this is rod rental, NOT boat rental), bait shop (sklep), on-site smokehouse + frying/grill room for caught fish (bar_gastronomia), and a "small accommodation base" / overnight stays + campfire (nocleg_domek); parking assumed for a rural drive-in venue. SOCIAL: the Facebook/Instagram/YouTube links shown on znajdzlowisko.pl belong to the directory itself (znajdzlowisko), NOT to this fishery, so they were deliberately left null. WEBSITE: official domain czarcijar.prv.pl is now just a parked alias redirecting to http://czarcijar.w.interia.pl/. Confidence=medium: identity, location, operator, commercial pay-per-catch model and species are well corroborated across independent sources, but prices and the Google rating could not be verified, and some forum sources note the venue's condition has declined in recent years.
