Small animal ear tags are self-piercing and can be used as operculum tags in aquatic research and aquaculture applications. They are also useful for monitoring fish habits, tracking growth rates and marking broodstock.
Tags are available in steel or mone (nickel-copper alloy), which is recommended for saltwater applications. The tag should be inserted in the operculum or lower jaw (always allow room for growth) and an applicator tool is required.
Steel tags are available in red (R), blue (B), green (G), and yellow (Y).
