Abstract

Abstract: Bloater Coregonus hoyi ( n = 48) were implanted with V9DT‐2x predation transmitters and monitored on 105 acoustic receivers in eastern Lake Ontario for >6 months. Twenty‐three predation events were observed, with predator retention of tags ranging from ≤1 to ≥194 days and 30% of retentions lasting >150 days. Long tag retention times raise concerns for acoustic telemetry analysis and the health of piscivorous predators retaining tags.
