Being able to individually follow fish <40 mm in length is a challenge for fish research. In the present study we examined whether the use of visible implant elastomer (VIE) tags is suitable for research on first‐feeding rainbow trout Oncorhynchus mykiss raised under laboratory conditions. We assessed the effect of tagging and tagging location on the growth and survival of juveniles over a 34‐d period. We also documented the retention rate and visibility of the tags under natural light. This study validates the use of VIE tags for 25–40‐mm fish under laboratory conditions, using the base of the dorsal fin and upper or lower caudal fin as tagging locations.
