Did you catch a tagged fish?
Tags of all kinds, in combination
with the location of fish capture if available, contain important information
for researchers studying fish behavior and movement. Some tags even have rewards
if returned! Be sure to call the phone number on the internal or external
tag, if present. You are also asked to contact the Pa Fish Commission Biologist
by calling the iTAG Hotline to supply vital research
information and collect more information about your fish.
What type of tag is it?
Common tags used in the Great Lakes
basin include external tags, internal tags, and jaw tags.
External “floy” tags are inserted along the spine, often at the
base of a dorsal fin and contain a unique code number with instructions for
reporting and returning. These can be either yellow or orange in color. Makes
no difference. It's only to grab your attention.
Internal tags are electronic transmitters and may contain important data with
a reward if returned. We prefer that you first call the iTAG
Hotline and have the Biologist collect the data from your fish. The
biologist will be glad to meet you when you come off the lake. Please
DO NOT FREEZE and handle with care! If you haven't done so already, immediately
remove the internal transmitters from the fish and rinse with water. Store
the transmitter at room temperature. Contact the iTAG
Hotline for how to return the tag. You may keep the fish for consumption.
Note: Rewards are offered for the INTERNAL transmitter tags only!
Jaw tags are metal tags attached to the jaw of the fish. Fish caught with
a jaw tag should also be reported by calling the iTAG
What information can you tell
me about the fish I caught?
Jaw tags and Internal tags both
hold interesting data about your fish. By reporting a tag, you can learn many
things about the fish including its age, travel history, where and when it
was tagged and much more!
Biologist Mark Haffley of the
PA Fish Commission inspects a tagged fish from Lake Erie.
Here, you see the bright orange
floy tag sticking out of the walleye's back. A sharp eye will see the tiny
writing on the tag.
Biologist Mark Haffley shows
the INTERNAL tag taken from the belly of the walleye.
A little larger than a AA battery, the
internal tag is carefully removed from the gut of the walleye. Notice the
reward info with phone numbers and important tag ID information. Treat these
with care! We prefer that you call the iTAG Hotline
Biologist Mark Haffley collects
valuable data of the walleye.
Several bits of data are taken such as
length, weight and age of your host fish before handing it over for consumption.
