Costa Del Mar Permit Tagging Research Program permit tagging instructions
It’s difficult to know exactly how to put a tag into a fish without having done it before. With the popularity of piercings these days, you’d think most people would have a good feel for how it’s done, yet popping a spaghetti tag along a spinal column is akin to picking the largest syringe in the lot for a cortisone injection—in other words, if you’re just a little off, there’s going to be a definitive knee-jerk reaction.
That being said, the only way to get good at tagging permit is to send a few fish off with some extra jewelry, and the best way is to avoid the learning curve that comes with trial and error and have someone who’s done it before walk you through the process. If the fish had a vote, I’m guessing there’d be a landslide for that option as well, which is why you’ll find the video at the end of this post.
Below is the recommended technique for tagging permit using the applicator and tags distributed through the Bonefish and Tarpon Trust Costa Del Mar Permit Tagging Research Program. Keep in mind that there’s a reason you’re pausing in the middle of your fishing trip—one that’s important enough that it’ll even get the needle-shy anglers on board involved. The information from tagging and recapture of tagged permit will provide information on movement patterns and growth rates of the species, so it’s worth taking your time and doing it right, as opposed to needlessly injecting a tag that’s going to fall out and join the sands of time on the bottom of the Atlantic or Gulf.
Once you get a few tags under your belt, the process will become second nature. Most taggers develop their own step-by-step process, and usually write the tag number down before inserting it into the tagging stick, because in the excitement of the moment it’s common to release a tagged permit only to find that you forgot to record the tag number. That leads to examining every tag closely to determine the missing tag number, which for anyone over 40 means the kind of squinting that leads to crows feet and your friends asking if you just finished watching a Clint Eastwood marathon. Also, you have to remove the fish from the water to read the number once the tag is inserted, and when you do that, the constant opening and closing of the fish’s mouth is it’s way of saying, “water, dude, I need w-a-t-e-r.”
There are times when you can’t keep the fish in the water. To weigh the fish, you’ll have to remove it, and some of the larger permit can be difficult to hold onto at the side of the boat, particularly if you’re the one who just fought and laded the fish and have the jelly arms and cramped, claw hand that go along with the process. If that’s the case, have the information sheet and measuring tape out, tag number written down, tag in the applicator and hand scale ready, then rip through the process. If done efficiently, the fish should be back in the water in less than a minute with a story to tell the other fish about the ugly guy in the blue hat who gave it some new shoulder jewelry.
The BTT Costa Del Mar Permit Tagging Research Program Tagging Kit
When you apply to help with the permit tagging program, you’ll receive a kit that includes: tags, a tag applicator, datasheet for recording tagging, a pencil, measuring tape and tagging instructions. Weighing the fish is optional, but it can provide additional growth information, so it helps to have a hand scale on board.
The information below is provided to help with the tagging process.
Tagging a Permit
- It is best to have two people present when tagging permit to reduce time needed to tag and to reduce handling time. Some anglers and captains experienced in tagging are able to tag permit solo.
- Have the tag inserted into the applicator and ready to go before landing the permit.
- If possible, keep the permit in the water during the tagging process.
- Measure the fish.
- Use the tip of the tag and applicator to scrape away one or two scales. This provides easy entry of the tag.
- Push the tag applicator into the fish with a swift motion.
- Insert the tag far enough to allow the barb to become lodged in the bones (called pterygiophores) descending from the dorsal fin. Sometimes a slight “click” can be felt as the barb slides over a bone and locks behind it. Please be sure the barb on the tag is fully inserted into the bones. A tag that is only in the meat of the fish will eventually fall out.
- Pull back on the applicator to remove it from the fish. Give the tag a slight tug. If set correctly, you should see a small section of dorsal musculature move on the other side of the dorsal fin.
- Make sure you note the tag number!
- Record the data on the enclosed data sheet
Care and Storage of the Tags
The tags should not be subjected to heat (such as prolonged direct sunlight). Keep in a location protected from prolonged sun exposure and heat.
Care of the tag stick
The tip of the applicator should be kept sharp to a V point. Store the applicator so the point is protected to prevent bending or dulling the point.
