Within Recipe, the Fishing subtype gets its own tracked table here. Each row below carries its own price-history page rather than sharing a single blended entry.
Fishing listings clear and replenish at whatever pace the in-game market sets; some subtypes trade in volume, others sit static for stretches. The price-history chart on each row's detail page makes that pattern visible at a glance.
