Dipping into the crystal-clear waters off Oslob, one can’t help but feel a sense of anticipation. With a quick adjustment of the mask, the eyes scan the horizon in search of the magnificent whale sharks, the largest fish in the world.
Scientifically known as Rhincodon typus, these gentle giants are famous for their immense size, docile nature, and distinctive spotted pattern. Despite their name, they are actually filter-feeding sharks and not whales. They can be found in tropical and warm-temperate waters across the globe, often near coastlines and in areas abundant with plankton. However, there is still much to learn about their life history, including their lifespan and social behavior. These endangered species face numerous threats such as overfishing, bycatch, habitat degradation, and climate change. International collaborations are crucial in protecting them.
Whale shark tourism has become a popular eco-tourism activity worldwide due to their calm demeanor. In fact, it contributes to 57% of shark and ray tourism globally, with opportunities to snorkel with whale sharks now available in 19 countries!
However, the rapid growth of wildlife tourism brings its own set of challenges. In Oslob, tourists can observe whale sharks up close as they are fed varying amounts of sergestid shrimp. Started in 2011, this practice has led to increased site fidelity of the sharks but has negatively impacted the health of the local reef ecosystem. The targeted whale sharks have also displayed altered behaviors such as increased vertical feeding and desensitization to human contact.
To assess the impact of tourism on whale sharks, researchers equipped 16 individuals with tri-axial acceleration loggers. The data collected revealed changes in their activity levels, tailbeat frequency, and metabolic rate while in the tourism area. The team suggests focusing on reducing the energy expenditure of whale sharks through operational changes rather than solely relying on the quantity of food provided. They emphasize the need for responsible and sustainable practices to ensure the well-being and conservation of these magnificent creatures.
In conclusion, while whale shark tourism offers a unique and awe-inspiring experience, it is important to strike a balance between human enjoyment and the conservation of these endangered species. By implementing appropriate regulations and management practices, we can continue to appreciate the beauty of these gentle giants while ensuring their long-term survival.
