The shark is a protected species. However, its capture, hunting and marketing continues to be perpetuated among poachers and sometimes even are legalized in some countries. We sometimes hunt them down to eat them, to sell certain parts of their bodies (white shark jaws) or even, although this is rare, for pleasure. But the biggest motivation for this hunt is the use we make of shark cartilage.
Protection of sharks
As of April 2006, sharks are among the protected species in France (and therefore also endangered). It is the first territory to care about the survival of these large marine animals. Hunting, poaching and the sale of parts of sharks are then prohibited throughout the territory. Nevertheless, the fishermen continue their traffic, and sometimes fish for sharks to which they cut the fins before being thrown back into the sea. Tourism and trade are also factors disrupting the behavior of the animal and thus disturbing the whole ecosystem .
In the case of cancer (s) and / or tumor (s), we sell the benefits of shark cartilage. Shark cartilage, containing no blood vessels, is thought to contain one or more antiangiogenic substances. These prevent the development of new blood vessels and therefore the growth of cancerous tumors and the appearance of metastases. However, the research has not produced really conclusive results. One belief about the shark is that it could in no case have cancer. This assumption is not entirely correct, as he may be affected by it, even if his chances are considerably lower than that of any other living being. This “remedy” against cancers and tumors can be administered by injection of cartilage or in the form of capsules of shark cartilage. The decision to have you undergo such treatment is up to your doctor. It is very strongly not recommended during pregnancy or breastfeeding, or in children and people suffering from a wound following an injury or surgery. The great use of shark cartilage is therefore carried out in the medical environment. It would have the benefit of preventing or delaying the formation of cancerous tumors in the patient. However, the effectiveness of this treatment has never been demonstrated. Is it then necessary to put a species such as the shark in danger only because one supposes, without physical proof, that a treatment could act on any form of incurable disease?
