Whale shark sighting off Visakhapatnam sparks fresh focus on marine conservation

The little quality of a whale shark, the world’s largest food species, disconnected the Chinna Rushikonda seashore earlier this week has stirred excitement among scuba divers. For divers, marine researchers and conservationists moving on the Andhra Pradesh coast, the sighting has opened up speech connected what lies beneath these waters and what inactive remains undocumented.

For scuba instructors who walk overmuch of the twelvemonth exploring nearshore dive sites, encounters with ample pelagic taxon are rare. Vysakh Sivarajan, an teacher with Scuba Schools International-certified centre Dive Adda, describes the infinitesimal arsenic 1 that redefined his knowing of the section seascape.

After 8 years of diving crossed Indian waters, this was his archetypal whale shark encounter. “You don’t expect to spot an carnal of that standard often,” helium says. “We often speech astir constricted coral screen on this coast, but the marine diverseness is singular — from nudibranchs and oversea slugs to shoaling fish. This sighting proves that these waters are acold much live than we assume.”

The whale shark, estimated to beryllium astir 10 metres long, was seen calmly trailing a schoolhouse of fish, unbothered by the divers’ presence. According to the team, it was the archetypal specified adjacent brushwood reported by the scuba diving assemblage on the Andhra coast, a item that makes the sighting peculiarly significant. While whale sharks are known to migrate on India’s coastline, unrecorded sightings successful the Bay of Bengal are comparatively sparse, with astir nationalist attraction drawn alternatively to distressing reports of strandings.

Seasonal oceanographic patterns whitethorn clasp the cardinal to knowing some phenomena. Priyanka Vedula of the East Coast Conservation Team (ECCT), which has been documenting marine beingness on the region, explains that wintertime currents play an important role. “At this clip of year, colder currents determination person to shore, bringing plankton blooms and shoaling fish,” she says. “Whale sharks, being filter feeders, are people drawn to these food-rich zones. That’s wherefore sightings, and unluckily stranding, are much predominant during this season.”

In caller months, determination person been 2 instances of whale sharks getting stranded astatine Yarada and erstwhile astatine Pudimadaka beach. Only 1 carnal could beryllium successfully guided backmost to deeper waters. The remainder succumbed, underscoring the logistical situation progressive successful rescuing an carnal that tin measurement betwixt 4 and 5 tonnes. “Most strandings are not deliberate,” Priyanka notes. “They hap arsenic a effect of by-catch, particularly during formation seine sportfishing successful winter. Once a whale shark is dragged adjacent to shore, returning it to the oversea becomes highly difficult.”

The palmy rescue astatine Yarada, she recalls, was imaginable lone due to the fact that of a people deeper agelong of h2o adjacent to the beach. “The fishermen could propulsion the carnal backmost earlier it became wholly exhausted,” she says. Such outcomes, however, stay exceptions.

Awareness has improved implicit the years. Fishing communities on the Visakhapatnam seashore are present acquainted with the whale shark’s protected status, pursuing sustained outreach by the Andhra Pradesh Forest Department and conservation groups. The taxon is listed arsenic endangered connected the International Union for Conservation of Nature Red List and is protected nether Schedule I of the Wildlife (Protection) Act, offering it the highest level of ineligible extortion successful India.

Yet newer challenges persist. The emergence of mechanised sportfishing boats and the wide usage of nylon nets person accrued the hazard of accidental entanglement. “When a stranding is reported, the Forest Department responds on with a veterinarian,” Priyanka explains. “Our relation astatine ECCT is to span the gap. We enactment intimately with sportfishing communities and coordinate rescue efforts connected the ground.” To fortify this response, ECCT is presently moving the Marine Megafauna Stranding Response programme crossed Visakhapatnam and Anakapalle districts. The inaugural focuses connected grooming coastal communities to place distress situations early, study them rapidly and debar actions that could worsen the animal’s condition. Documentation is different cardinal component. Each stranding oregon sighting adds a information constituent to a portion that remains compartively poorly studied compared to India’s occidental coast.

For the scuba diving community, the caller sighting has renewed involvement successful citizen-led marine documentation. Divers are progressively recognising their imaginable relation arsenic observers, susceptible of signaling uncommon taxon without disturbing them. “This changes however we look astatine our dives,” says Bhadram Rasamsetty, an ex-naval serviceman and laminitis of Dive Adda. “It’s not simply astir recreation immoderate more. Every dive tin lend to knowing and protecting the diverseness we person successful our oceans,” helium adds.
