That is something could have been noted various other shark types within the Canary Islands plus Their state

  • Repellant lookup. Present scientific testing have focused on the fresh new steps and additionally chemical substances, acoustic, artwork and you may electro-magnetized repellents. Aforementioned is a location that i been employed by toward, and you may basically looks for a method to overstimulate the brand new sharks’ electrosensory program enough to establish a good repellant response.

But what regarding the Reunion Island in itself? It is true that when you see the size of the newest coastline (207km) alongside the amount of https://www.datingranking.net/croatian-dating shark hits (21 since the 2007), in comparison to other towns globally, the rate is large.

Besides the visible dependence on search becoming done towards this type of whales, there can be an urgent dependence on education, since the because of the research and technology globally, human-shark interactions are not completely got rid of. As a result, studies techniques have a tendency to bring safer behaviors in water profiles. These are generally such things as to prevent in water at the beginning and you can dusk, avoiding places where fishing is happening, to prevent murky estuarine surroundings to-name but a few strategies.
