title: Scale circuli patterns differentiate between hatchery-reared and wild Rutilus rutilus during evaluation of fish stocking.
abstract: Hatchery-reared and wild roach Rutilus rutilus were correctly classified to their rearing environment in a discriminant function using data on their scale circuli patterns. The discriminant function was then used to classify recaptured R. rutilus by their origin (hatchery-reared and wild) during a riverine stocking evaluation. At 8 and 18 months post-stocking, 10 and 7% of fish captured in the vicinity of the stocking site were classified as hatchery-reared.
