Trappers are required to submit a fully intact lower canine tooth, (preferably in the form of a lower jaw) from any bobcat, fisher, marten, and otter that is trapped or hunted. The law also requires collecting a small tissue sample from bobcat to confirm gender. These samples will provide us with the age and sex of the harvest, which will improve the management of these species. While this is an extra burden on the fur harvesting community, the information gained will benefit these species for all Maine citizens.
For each sample, trappers need to fill out a tag that is provided by the Department and attach it to that sample. Since location, age, and sex are used together in the analysis, it is very important that the information on the tag reflects the sample it's attached to.
It is the responsibility of the trapper/hunter to provide the above described sample free of skin and excess flesh, and with a filled out tag for every bobcat, fisher, marten, and otter that is harvested. These samples should be presented to the tagging agent when any fur/animal is tagged. The agent will get the samples to the Department for analysis.
Sample Collection Instructions
For Fisher, Marten, and Otter
- Remove a lower canine tooth or a lower jaw.
» If removing the lower jaw, it is not necessary to provide the entire jaw, just the front portion with both of the lower canines. To prevent damaging the canine root, make sure to cut the jaw so that 3 teeth are left behind the canine teeth
- Fill out tag and attach to jaw.
- If providing only a canine, place canine and filled out tag into a sealable plastic bag.
- Collect tissue sample from any part of the muscle. This can be taken from any part of the muscle. One of the easiest places is to cut off a 1/2 inch portion of the tongue.
- Place tissue sample in seal-able plastic bag and keep frozen to prevent the DNA from degrading.
- Fill out tag and place in bag.
- Remove lower jaw with both canines, see (Figure 1 - complete and partial jaw) below, or pull a lateral incisor tooth, see (Figure 2) below.
- Please ensure that the entire incisor tooth is removed. If the root is broken, we will not be able to age the animal.
- If removing the lower incisor, it is easiest to do this after having soaked the skull in almost boiling water, and pull tooth with needle nose pliers, or use a razor blade to slide down along each side of the tooth then use a pair of needle nose pliers and pull straight up to remove tooth; this should only be done with a fresh/completely thawed skull.
