Abstract
We evaluated methods to
attach PIT tags and transmitters to freshwater mussels. Mussels
received externally-mounted PIT tags using cyanoacrylate or underwater
epoxy, and a sub-group of those with PIT tags attached using
cyanoacrylate also received dummy transmitters. Tag retention and
survival were 100% after a 30 day laboratory observation period for
each method. During the subsequent 18 months of field observation,
underwater epoxy and cyanoacrylate proved to be adequate adhesives for
attaching PIT tags and transmitters. Epoxy performed best with 100%
PIT tag retention. Cyanoacrylate also provided high retention rates of
PIT tags and transmitters, >90%. Mortality was minimal at 4.7% for
all relocated mussels over 18 months. All mortalities were those
tagged with cyanoacrylate. Three of the mortalities occurred among
mussels fitted with dummy transmitters, and seven among PIT tags only.
Percent recapture of the different tag/adhesive combinations ranged
from 48–77.5% during 6- and 18-month surveys. Results suggest both
adhesives provide a reliable method for external attachment of tags
during freshwater mussel research; however, epoxy may be better suited
because of slightly higher tag retention and reduced emersion times
during attachment.
