    For internal and external tagging

    Star-Oddi offers a floating device for the DST loggers. The floats can be used both for internal and external tagging. The floats come with a stainless steel wire for attaching to a DST.  

    Increases the tag retrieval rate

    Most fish tagging projects rely on tags to be returned by commercial fishermen. The buoyancy force is slightly net positive for the combination of tag and floats, meaning if a DST tagged fish with a float is not recaptured, the tag will eventually detach from the fish, float to surface and reach shore. With the hope of someone spotting the tag at a beach, the float can increase tag retrieval rate. The DST has printed return information on its housing.

    Bright colour available

    The floats have a bright red colour to make them easier to spot. For internal tagging the floats are coated with biocompatible epoxy material.

    Customized sizes

    Each standard float is 24 mm in length. Dimension depends on size of DST used. As an example, DST milli-TD requires four floats on a wire, each of them 13.5 mm in diameter. Another option is to use three floats with the DST milli-TD where diameter is 16.2 mm. DST micro-TD requires three floats where each is 9.2 mm in diameter and 24 mm long. DST centi-TD and CTD require five floats that are 16.2 mm in diameter and also 24 mm long.
