![]() With this in mind, it becomes essential that experienced taggers are called on for such projects. Some sharks are small and calm enough to be brought onto the deck of the boat, but most others will need to be tagged as they are suspended in the water. Upon capture, fishermen or researchers need to assess the size and features of the particular specimen so that they don’t attach a badly-fitting tag, as this would make it ineffectual. Satellite tracking tends to be very accurate as it provides more live time tracking, with delays being minimal (usually only a few hours). The satellite receptor is secured with a set of bolts to the shark’s dorsal fin, and provides migration information each time it surfaces. In satellite tracking, scientists use a device called a satellite receptor. ![]() It will be secured to the fish using a brightly coloured string or nylon so that future captors can see from a glance that it is a tagged animal. In the case of tagged animals, this label will contain details about the animal, such as the date of capture, size, sex, and species. Should a tagged or tracked animal die, the data collected will be invalid and the population numbers inaccurate.īoth methods of tracking involve a small tag or device to be secured onto the shark. Otherwise, a weakened and traumatised shark will be released into the ocean with a strong possibility of death soon after its discharge. Both of these methods inflict some minor trauma for the animal as it needs to be caught and immobilised for a brief period of time.Ĭaptors need to ensure that their method of catching and tagging the shark is as non-invasive and has as little of a negative impact as possible. Sharks are tracked either via satellite or by a process called tagging. Human beings are killing more sharks at a faster rate than the animals can reproduce, so keeping track of these sharks will allow scientists to oversee their survival and growth. All around the world, increased fishing combined with a slow maturation period has gradually dwindled the number of sharks down. Shark tracking, as mentioned before, can also help in the fight against shark endangerment. Therefore, tracking is essential, as it reveals to researchers their migratory patterns, helps determine their life spans and population numbers, and so on. For this reason, they are not always easy to locate. There are hundreds of shark species living in the open ocean and some species reside in unimaginable depths. On top of being vital for the protection and conservation of the many shark species, such facts raise awareness amongst common people, who are then better equipped to avoid attacks and play their part in preserving the marine environment. There has been a multitude of theories, myths, and tales about them, but it is only in recent years that scientists and researchers have made headway with establishing concrete facts about this predatory fish. ![]() ![]() Sharks have been an elusive and mysterious fish for centuries. Shark tracking and conservation is more important than ever as more and more shark species become endangered, so how is it that scientists do this? Why Is Shark Tracking Necessary? There are some amazing apps and websites that let you track your favorite sharks and see their movement history. Shark tracking is done by tagging and by satellite, and the best part is that it’s not exclusive to marine experts.
