Simple tips to Tag a Shark
Commercial label poles are around for purchase, or perhaps you can build your own personal.
Diagram for constructing label pole.
Firmly mount tagging needles in 1″ to 1?” diameter hardwood dowel.
Ensure the tagging needle runs out approximately 2?” from the pole.
Fit the dart mind loosely to the point that is slotted the needle. It ought to be curved so the two points that are rear face downwards to the muscle tissue if the label is placed.
Spot elastic bands across the capsule in the pole to carry the label set up.
Placing a label
Tag pole with label showing proper positioning near first dorsal fin.
Tags must certanly be placed to the muscle mass regarding the straight back nearby the very very first dorsal fin at an angle toward the top associated with the seafood.
Aim the label during the root of the very very first fin that is dorsal the 2 back points dealing with the shark and quickly thrust downward.
Tag Location on Shark
Drawing of shark showing label positioning underneath the very very first dorsal fin aided by the metal dart beneath the sharks skin plus the capsule trailing toward the end.
The dart mind should approximately come to rest 1″ to 1?” underneath the shark’s epidermis using the capsule trailing far from the mind associated with the shark.
In tagging little sharks, care should be taken up to avoid problems for the backbone. To regulate the depth of penetration, make an incision with all the point of the blade and push the dart carefully go to the muscle mass.
Try not to tag sharks not as much as 3 foot in total with dart tags.

What direction to go if You Catch a Tagged Shark
It, we ask that you record the following information as accurately and completely as possible when you catch a shark with a tag in:
Tag quantity, kind, and color
Species and intercourse
Date of capture
Location caught (latitude and longitude preferred)
Length and/or fat and whether or not it ended up being measured or estimated
Form of size ( total or fork) and/or variety of fat (entire or dressed)
Fishing technique (pole and reel, longline, etc.)
Launch condition: did you keep carefully the shark or release it aliveif released alive, indicate whether released using the exact same label, a different tag, or no label and condition associated with the seafood
Make sure to consist of your title, mailing target, daytime telephone number, and current email address.
There are numerous methods for you to report this given information to us:
Mail into the information to Cooperative Shark Tagging Program, NOAA’s nationwide aquatic Fisheries provider, 28 Tarzwell Drive, Narragansett, RI 02882
We will deliver you a report with information about the shark you caught and a cap to many thanks for the involvement.
Request Backbones of Recaptured Sharks
If you’re maintaining the shark, please think over giving us a backbone test. The big quantity of sharks increasingly being recaptured supplies an unique chance of fishermen to help biologists in age and development studies.
To deliver us an example:
Record label recapture and number details (date, location, latitude and longitude, species, calculated fork size, intercourse, and way of capture).
Eliminate a 6 – 10 little bit of the backbone from on the gills.
Freeze the backbone.
Where you should simply just take backbone test and just how to determine the period of the shark.
