Every diver has one unforgettable moment. It may be the first time you watched a reef shark glide calmly across a coral reef, or the moment you witnessed such extraordinary marine life that it felt like entering another world. Experiences like these are what inspire so many people to fall in love with the ocean. A truly healthy ocean still contains every essential part of its ecosystem, including sharks.
Unfortunately, shark populations in many parts of the world are facing increasing pressure. One of the main causes is shark finning, a practice that has long been a major concern for conservation organisations. Recognising how this impacts the majestic sharks we admire can evoke responsibility and empathy in readers.
For us, discussing shark finning is not simply about conservation. It is about the future of the oceans you explore, the health of the ecosystems that make every dive so memorable, and how responsible dive tourism can become part of the solution.
What Is Shark Finning?
Shark finning is the practice of removing a shark’s fins and then discarding its body back into the sea. In many cases, the body is discarded because the fins have a much higher commercial value than the rest of the shark.
This practice has developed because of the demand for shark fins in international markets. As a result, many sharks are caught solely for their fins, while most of the body is never used.
Although several countries have banned shark finning and introduced stricter regulations, illegal finning persists in some regions due to enforcement challenges. Supporting international efforts and advocating for stronger policies can help close these gaps and protect sharks worldwide.
How Shark Finning Works
In simple terms, shark finning occurs when sharks are caught primarily for their fins because they command a high market price. In irresponsible practices, the shark’s body is then discarded at sea, meaning that only a small part of the animal is actually used.
Practices like these not only raise serious ethical concerns, but also accelerate the decline of shark populations in many parts of the world.
Why Does Shark Finning Still Happen?
The answer is not as simple as “because people catch sharks.”
A range of factors, including market demand, the high economic value of shark fins, and the complexities of international trade and regulations, influence the shark fin trade. In other words, shark finning is a global issue involving many stakeholders, not just a single country or community.
Understanding these underlying factors helps us recognise that the solution must also be collaborative, involving government policies, industry action, and the choices made by consumers and travellers. This shared effort can inspire hope and motivate responsible actions.
Why Sharks Play a Vital Role in Marine Ecosystems
Many people think of sharks simply as predators. In reality, their role is far more important.
Sharks are apex predators that help maintain the balance of marine ecosystems. Their presence helps regulate the populations of many other species, preventing any one group from dominating the marine food web.
In other words, sharks help keep marine ecosystems in balance.
Sharks Help Keep Marine Food Webs Balanced
Every species in the ocean has its own role to play.
When apex predators decline, changes can occur throughout the food web. Some species may become excessively abundant, while others decline. Over time, these changes can affect the stability of the entire ecosystem.
Healthy Shark Populations Support Healthy Coral Reefs
The relationship between sharks and coral reefs is not always immediately visible.
However, when the marine food web remains balanced, the pressures affecting different organisms within the ecosystem also remain more stable. These conditions help strengthen the resilience of coral reef ecosystems against other challenges such as climate change, pollution, and human activities.
The Impact of Shark Finning on Marine Ecosystems
So, what does shark finning have to do with your diving experience?
The answer is quite simple.
As shark populations continue to decline, the consequences extend beyond sharks. The entire marine ecosystem is affected.
Fewer Shark Encounters at Dive Sites
Many divers dream of seeing sharks in their natural habitat.
However, in some parts of the world, those opportunities are becoming increasingly rare because of the ongoing pressure on shark populations.
Analyses of the shark fin trade have shown that many fins come from coastal shark species. This is particularly significant because many of the world’s most famous dive sites are located in coastal and tropical waters that also serve as habitats for these species.
This means that the very destinations renowned for world-class diving also require long-term protection.
Changes to Marine Biodiversity
When shark numbers decline, the effects do not stop with a single species.
Fish community structures can change, predator-prey relationships can shift, and the balance of the ecosystem can begin to change. These changes often happen gradually, making them difficult for divers to notice during a single trip.
However, when viewed over the long term, the differences can become striking.
Oceans once filled with diverse marine life can gradually lose biodiversity if pressure on the ecosystem continues.
Less Resilient Coral Reef Ecosystems
Coral reefs face many challenges, from ocean warming to pollution.
When shark populations decline, one of the natural mechanisms that helps maintain ecological balance weakens. As a result, the ecosystem’s ability to remain healthy amid multiple pressures can decline.
This is why shark conservation is not only about protecting a single species. It is about safeguarding the entire marine ecosystem.
Why This Matters for Every Diver
You might be wondering, “I just want to enjoy diving. Why should I care about shark finning?”
The answer is that every dive depends on the health of the ocean.
When the ocean is healthy, you have a greater chance of experiencing thriving coral reefs, abundant pelagic fish, and encounters with sharks in their natural habitat.
By contrast, when marine ecosystems face long-term pressure, the quality of the diving experience can also change.
Every Dive Depends on a Healthy Ocean
Many factors contribute to an unforgettable dive.
It is not only about excellent visibility or calm weather, but also about the richness of marine life you encounter beneath the surface.
At La Galigo, we have always believed that the best diving experiences begin with a healthy ocean. That is why conservation is not simply an added benefit. It is essential to the future of diving.
Diving Tourism Can Help Protect Sharks
The good news is that divers can actively support shark conservation through responsible behaviours, such as avoiding products made from shark fins, choosing eco-friendly tour operators, and advocating for marine protected areas. These actions help ensure sharks remain a vibrant part of the ocean you explore.
Responsible ecotourism demonstrates that sharks are far more valuable alive in their natural habitat. A single shark swimming freely in the wild can attract visitors for many years, providing economic benefits for local communities while raising awareness of the importance of conservation.
In other words, responsible dive tourism helps create an economic incentive to keep sharks alive.

How Divers Can Help Protect Sharks
Protecting sharks does not always require major actions.
As a diver, you can make a meaningful contribution through the choices you make before, during, and after your trip.
Some simple ways you can help include:
- Avoid buying products made from shark fins.
- Avoid consuming shark fin soup to reduce market demand.
- Choose dive operators that follow sustainable tourism practices.
- Maintain a safe distance when encountering sharks, without chasing or disturbing them.
- Follow responsible diving guidelines that respect marine wildlife.
- Share positive experiences about the importance of shark conservation with your family and friends.
Although these actions may seem small, the collective choices of many individuals can make a far greater long-term impact.
Final Thoughts
Shark finning threatens not only shark populations but also the balance of the marine ecosystems that make every dive so special. By understanding the importance of sharks and supporting responsible tourism practices, you can help protect the health of our oceans for future generations.

Frequently Asked Questions
What is shark finning?
Shark finning is the practice of removing a shark’s fins and then discarding its body back into the sea. This practice occurs because shark fins have a high commercial value in international markets. Shark finning is considered one of the most serious threats to shark populations because it drives large-scale shark capture.
Why is shark finning harmful?
Shark finning contributes to the decline of shark populations worldwide. Because many shark species grow slowly, reach sexual maturity relatively late, and produce only a small number of offspring, their populations take a long time to recover after exploitation. The loss of sharks can also disrupt the balance of marine ecosystems.
How does shark finning affect marine ecosystems?
Sharks are apex predators that help maintain the balance of marine food webs. When shark numbers decline, other species can become unbalanced, ultimately affecting marine biodiversity and the health of marine ecosystems, including coral reefs that provide habitat for thousands of species.
Does shark finning affect diving experiences?
Yes. Healthy oceans with stable shark populations generally support more balanced ecosystems and richer marine life. If shark populations continue to decline, divers may encounter sharks less frequently in their natural habitat, and ecosystem changes can also affect the quality of the diving experience over the long term.
Is shark finning different from shark fishing?
Yes. Shark fishing refers to the capture of sharks in general, which in some regions may be legal and strictly regulated. Shark finning is the practice of removing a shark’s fins and discarding its body, which many countries have banned because it is considered both unsustainable and unethical.
Is shark finning still legal?
Regulations vary from country to country. Many nations have banned shark finning and introduced policies requiring sharks to be landed with their fins naturally attached. However, the shark fin trade remains a challenge in some regions, meaning effective law enforcement and international cooperation are still essential.
Can divers help protect sharks?
Absolutely. As a diver, you can help protect sharks by choosing dive operators that follow sustainable tourism practices, avoiding products made from shark fins, refusing to consume shark fin soup, respecting marine life while diving, and supporting shark conservation and education initiatives.
Why are sharks important for healthy oceans?
Sharks help maintain the balance of marine ecosystems as apex predators. Their presence regulates the populations of other species, helping keep marine food webs balanced. Healthy ecosystems ultimately support more resilient coral reefs, greater biodiversity, and better diving experiences.
Where can you see sharks responsibly in Indonesia?
Indonesia offers many destinations where you can encounter sharks in their natural habitat, including Raja Ampat, Komodo, Alor, and the Banda Sea. To support shark conservation, choose a liveaboard or dive centre that follows responsible diving practices and respects marine wildlife.
