Bead size guide
Best Bead Size & Colour for Chum in High & Coloured Water
Quick answer: a 19mm bead (16–19mm) in Chartreuse, Hot pink, Purple.
Big and bright for low visibility.
Every experienced Chum angler adjusts bead size and colour to the day's water, not a fixed favourite. The calico tiger of late fall — last fish of the season, biggest roe. High & Coloured conditions change what the fish can actually see and how far a bead has to be noticed from — and the right size follows from that. Big and bright for low visibility. For chum specifically, that means leaning on chartreuse, hot pink, purple in the 16–19mm range rather than a one-size-fits-all pick. Quick ID if you're new to the species: white mouth/gums; no spots; calico bars spawning; white anal-fin tip; dog teeth. The recommendation below (built around a 19mm bead) is the starting point — every Chum trip still rewards experimenting once you're on fish. Water conditions shift day to day and even hour to hour, so treat this as a confident starting point, not a fixed rule. The full picture for chum across every water condition — low, prime, high and blown out — is available in the interactive Bead Match tool, linked below this recommendation.
