SHARK FINNING

It is estimated the over 73 million sharks are killed by "finning". Finning is when sharks fins are taken off for a Asian dish called fin soup. The sharks are normally normally finned while they are still alive which leaves them to sink to the bottom of the ocean.


BYCATCH

Sharks also face the problem of getting caught up in fishing nets left out by fishermen


MEAT SKIN AND LIVER OIL

Sharks are also hunted for their meat, which is sold at markets and used for consumption. Their skin is used for leather and their liver oil for cosmetics, lubricants and a source of vitamin A.


Sharks face these threats and many more the number of sharks is decreasing at an alarming rate. Because sharks only reach a reproductive age at 12 they fiend it hard to recover the population. 74 out of the 465 assessed species of sharks are classified as threatened including 11 which are classed as critically endangered
