The Importance of Sharks in Our Ocean – more than just Awesomeness

By: Cris Merz

Apex Predators – that is what they are.  Often the baddies in movies, whether it is terrorizing a peaceful beach, swinging about in tornados killing people in landlocked towns or eliminating the English spy with “lasers” on their foreheads.

They have the notoriety of being tough, relentless, and a powerful killing machine.  Unfortunately, they are the victim of a reputation that labels them as mean, vicious and unforgiving.  Like most endangered species, they have also become trophies to many hunters.  Shark fishing competitions are held all over the globe.  NBC Sports even had a program dedicated to the competitive fishing of sharks.

The fact is, they need love, more than anything.

Population Decline

According to, about 1/3 of all sharks are threatened with extinction.  80% of ocean shark species are at risk from high seas fisheries.  Because of the exposure that sharks have to these high seas fisheries using such fishing arts such as long-line, shark populations of hammerheads, silky, oceanic, mako and tigersharks in areas that once had a healthy population are experiencing declines of up to 90%.  The fact that sharks have a very low reproductive cycle and often reach maturity as long as 33 years in the case of many females, overfishing has a huge impact on populations.

The population of sharks is greatly affected by industrial fishing.  WildAid estimated that approximately 100 million sharks are killed each year.  73 million for the purpose of shark fin soup.

Shark Fins and Soup

Shark fin soup became a delicacy one thousand years ago, in the Sung Dynasty.  Currently, it has become a symbol of prosperity and wealth.  The sad part about all this – is that it is tasteless.  The shark fin itself adds the rubbery texture to the dish but it does nothing for the taste.  As a matter of fact – the only real flavor to the soup is the essence of chicken because that is what it is, chicken broth.

As a dish that usually goes for $95 a bowl but all the way up to over $100 depending on your location, it is usually reserved for grand occasions like high profile business lunches or wedding parties.  Though an unsustainable fishing practice, those that speak on behalf of shark fin soup claim that bans are culturally discriminatory.  Over the last five years, more and more awareness has been spread through campaigning and social media to encourage consumers to not only boycott places that serve soup, but to also boycott airlines and carriers that ship them. A huge victory for sharks was when Air China banned the cargo of shark fin soup joining 36 other carriers.  And while the likes of UPS and DHL have banned cargo containing shark fin back in 2015, FedEx has still to commit claiming that what they do is “legal.”

The Importance of Sharks in Our Ocean

Besides the awesomeness that it is diving side-by-side with a school of hammerheads, or snorkeling next to a 40 ft whale shark gulping on plankton with an open mouth that could swallow you whole, it is very good for tourism.  There are so many destinations that have become “must see” bucket list places for divers.  Coco, Socorro Islands, Galapagos Isla Mujeres are all destinations that offer high impact diving or snorkeling that allows divers to experience some very close encounters with these apex creatures.  However, it is not the sustainable industry of tourism that makes sharks important to planet earth, although it is a favorable argument when trying to not only enact laws but also enforce them in many marine reserves that are shredded daily by illegal fishing, it is important to the ocean itself as an ecosystem.  To quote the famous line from underwater awareness guru and Jedi Master Obi Wan “Ben” Kenobi, “It brings balance to the Force”.

Bringing Balance to the Ocean

Sharks are top of the food chain.  As an apex predator, they keep other populations in check.  By being extremely effective in their feeding habits, sharks often feast on the old or sick grooming the populations of predators that may be directly beneath them.  Eliminating them from the food chain would cause a potential devastation to other species that share the habitat with sharks.  Their role in the ocean heavily affects the general health of the population as well and maintaining a diversity by keeping other predator’s populations in check.  Removal of sharks could also change hunting habits as well as feeding habits of other species that could influence seagrass, corals as well as the collapse of other fisheries.

“One study in the U.S. indicates that the elimination of sharks resulted in the destruction of the shellfish industry in waters off the mid-Atlantic states of the United States, due to the unchecked population growth of cow-nose rays, whose mainstay is scallops. Other studies in Belize have shown reef systems falling into extreme decline when the sharks have been overfished, destroying an entire ecosystem. The downstream effects are frightening: the spike in grouper population (thanks to the elimination of sharks) resulted in a decimation of the parrotfish population, who could no longer perform their important role: keeping the coral algae-free and therefore reducing the oxygen quantities in our atmosphere. The knock on effects of this could be devastating for all life on Earth.”

What Can I Do To Help?

People often ask; what can we do to help?  I am just a person?

  • First and foremost, do not buy food containing shark fin.
  • Always opt for environmental and sustainable alternatives and substitutes. It isn’t just about the shark meat. Shark cartilage and oils are found in a range of products from beauty items to health nutrition. By boycotting shark products, you will reduce market demand.
  • Contact your elected officials asking them what steps they are taking to end the unregulated trade in shark fins. Let your legislators know that sharks are important to you.  Ask them to introduce and support legislation that will list sharks as protected species.  This has helped in many cities across the globe forcing restaurants to take shark fin soup off the menu.
  • Stay current through social media and other publications to see what is being done and how you can help, whether it is just by taking a pledge or sharing it with your friends. Tell your friends and relatives that they may be contributing to the irreversible decline of shark populations.

Speak out when you see abuse.  This can mean anything from molesting sharks during a dive or fishing for them illegally.

  • Stay informed and share. Learn how different human activities put sharks at risk. By educating yourself on the issues, you can find effective ways to help by speaking at local clubs, schools and other local venues that might create awareness. By understanding the issues, you can teach others about sharks and inspire them to get involved as well.
  • Reduce Your Seafood Consumption. No one likes to hear this.  Unfortunately, commercial fishing impacts the sharks negatively in more than one way.  Besides reducing their own source of food, sharks are themselves a byproduct of commercial fishing.
