In fact, the population of this shark shared between Argentina, Brazil and Uruguay was listed as “ Critically Endangered” by the International Union for the Conservation of Nature, which is the main international organization dedicated to the evaluation and preservation of biodiversity. The latest scientific analysis indicates that the abundance of this species has decreased drastically in Argentina.
The coasts of Buenos Aires are very important in the life cycle of this species, since it is believed that they mate in these waters, and that is fundamental for the preservation of the species. Once they reached the reproductive age, they give birth to two offspring, with a maximum frequency of once every two years. Female sharks reach their reproductive age at 14-15. The sand tiger shark, or “escalandrún”, is a shark of seasonal occurrence that moves between Argentina, Brazil and Uruguay, so it is affected by fishing activities in these three countries. They are based on scientific knowledge of the biology of these species in Argentine waters accumulated over many years, which indicate that these sharks have a very low reproductive rate and that their populations have suffered severe declines. These regulations are intended to preserve and make sustainable use of large sharks populations of the Argentine Sea. 04/2013 of the Federal Fisheries Council is still valid, and it establishes that commercial fishing vessels can not land sharks longer than 1.6 meters in any Argentinian port.
These regulations establish that captured sharks of the species sand tiger shark (Carcharias Taurus), Bacota (Carcharhinus brachyurus), Leopard (Notorynchus cepedianus), Hammerhead (Sphyrna zygaena) and Cazón (Galeorhinus galeus) have to be returned to the sea, limit the number of rods per fisherman and also stipulate how fishing rods should be assembled.
In principle, the catch shown in the video is illegal because it violates Articles No. On January 11, a video showing what appear to be recreational fishermen in a rigid inflatable boat, with an illegal catch of 8 sharks of the species commonly known as sand tiger shark (Carcharias taurus) in waters off Mar Chiquita, province of Buenos Aires, was broadcasted by the media and in social media.
