Diagram for constructing label pole.
Securely mount tagging needles in 1″ to 1?” diameter hardwood dowel.
Make sure the tagging needle runs out approximately 2?” through the pole.
Fit the dart mind loosely to the point that is slotted the needle. It ought to be curved so your two back points will face downwards into the muscle mass as soon as the label is placed.
Spot elastic bands round the capsule in the pole to put on the label in position.
Placing A label
Tag pole with label showing correct placement near first fin that is dorsal.
Tags must certanly be placed in to the muscle mass associated with the back nearby the very first dorsal fin at an angle toward your head associated with seafood.
Aim the label during the foot 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 tag placement underneath the very very first dorsal fin aided by the steel dart beneath the sharks skin together with capsule trailing toward the end.
The dart mind should come to sleep more or less 1″ to 1?” underneath the shark’s epidermis using the capsule trailing far from the mind associated with the shark.
In tagging tiny sharks, care must certanly be taken up to avoid problems for the backbone. To regulate the level of penetration, make an incision using the point of a blade and push the dart carefully go to the muscle tissue.
Usually do not tag sharks significantly less than 3 feet in total with dart tags.

We shall deliver you a written report with informative data on the shark you caught and a cap to many thanks for the involvement.
Ask for Backbones of Recaptured Sharks
If you should be maintaining the shark, please contemplate delivering us a backbone test. The big amount of sharks increasingly being recaptured supplies an opportunity that is unique fishermen to aid biologists in age and development studies.
To deliver us a sample:
Record label recapture and number details (date, location, latitude and longitude, species, calculated fork size, sex, and way of capture).
Eliminate a 6 – 10 little bit of the backbone from on the gills.
Freeze the backbone.
Locations to simply just take backbone sample and just how to look for the duration of the shark.
