OpportunityTitle: Rio Grande silvery minnow Transgenerational Tagging Technique
AdditionalInformationOnEligibility: Single Source
Description: We are proposing to investigate a trans-generational tagging technology that if successful, will allow us to monitor the progeny (larvae and juveniles included) of stocked fish as well as the released fish themselves. To date, we have successfully initiated a batch marking technique for adults (Visible Implant Elastomer), and an individual marking technique (PIT tag) for large adults, but have yet to test and implement a successful technique for marking larval and juvenile Rio Grande silvery minnow. In short, this technique involves the tagging of pre-spawn females with one of several isotopes and following that isotopic signal through the population. This technique has been used on a variety of other fishes, but must be tested on Rio Grande silvery minnow in a laboratory environment before use in the field. The priority for this project is to determine the effectiveness and implement a new tagging technique for Rio Grande silvery minnow. The objective, as identified in the Recovery Actions and Narrative in the Revised Recovery Plan.
