A immature whale calf has been discovered deceased after becoming entangled in a protective barrier near the beaches of NSW.

The juvenile whale was found entangled in mesh north of Wollongong on Tuesday, specifically the ocean between Coledale and Wombarra.

This occurrence is the 15th cetacean trapped in marine barriers off the coast of eastern Australia so far this year, and the first cetacean to have died, believed to have been suffocated during its journey toward the south.

Finding and Reaction

An official for the state department handling fisheries and regional matters explained that shark meshing contractors found the deceased whale in the course of a standard check early Tuesday.

No earlier notifications any reports of a whale entanglement near Coledale before this incident,” the spokesperson added, adding that no further cetacean traps in coastal barriers had been reported so far this year.

But, during June, a marine mammal was trapped in a drumline setup along the Newcastle coast.

Marine protection agencies, the Organisation for the Rescue and Research of Cetaceans in Australia and emergency responders took action later that day, finding the immature whale with net tangled around its rear and side appendages.

“Everyone involved made every effort to disentangle the dead cetacean,” said Marine Rescue NSW inspector the inspector.

Challenges and Outcome

The strategy was to take the carcass to a location where extraction was possible from the water,” the inspector explained. Shortly before 3pm, “the situation of unfavourable sea conditions and the nearby rocks and beach made it hazardous for the rescue team to remain there, so we were forced to abandon”.

The body came onto the beach later that day. ORRCA said in a statement: “For now, the cause of death is unknown and won’t be confirmed until … a autopsy is performed.”

Marine Barrier Program Details

In place are over fifty nets installed in the region, which are fitted with sound-based alerts and “dolphin pingers”.

The devices “produce a high-pitched acoustic signal that repels the cetaceans from the zone and reduces the chances of entanglement,” the official said.

“The government is researching advanced marine safety methods aimed at reducing effects on ocean life while ensuring safety for beachgoers.”

Demands for Action

The calf’s death caused renewed demands for the NSW government to terminate its netting system.

Politician Cate Faehrmann remarked it was “absolutely heartbreaking to witness a baby humpback whale perish in this manner, especially because its passing was entirely unnecessary”.

“Annually when the nets go in, we observe more whales and additional creatures including dolphins, threatened sea turtles and rare nurse sharks ensnared, wounded or deceased.”

Specialist Opinions

University expert, who researches sea animals at Griffith University, said data is limited to indicate that shark nets averted marine incidents previously.

Extensive elimination of sharks by shores for safety reasons” had minimal impact on risk, Meynecke explained.

The researcher stated juvenile cetaceans were more vulnerable of capture and death.

“It is understood that they are not aware the hazards posed by netting.”

Whales develop experience, acquiring communication skills regarding hazardous areas, he said.

An immature cetacean “would panic quite quickly and with rough ocean conditions there exists the danger of suffocation”.

Official Reactions and Options

Greens senator the senator commented: “Governments can help protect marine visitors by boosting funding in current solutions to archaic and useless marine barriers and deterrents.

“These include subsidising personal shark repellents, monitoring systems, sustainable marine protections, bite-proof wetsuits, and bettering informational efforts.

“A government study regarding ocean threats advised national authorities show national leadership on driving this investment, but this has so far been ignored.”

Whish-Wilson also called on the national authorities to eliminate a loophole in the national environment law that enables local marine elimination initiatives.

“National legislation allows the officially permitted marine mammal suffering that is occurring near Australian beaches using risky and old-fashioned EPBC exemption.

“The moment has come to terminate the global lengthiest sea creature removal and cease this inhumane officially permitted creature suffering.”
