A juvenile humpback whale was found deceased after getting trapped in a protective barrier off the coast of NSW.

The 8-metre whale was found wrapped in mesh north of Wollongong this Tuesday, particularly the sea separating these coastal towns.

This event is the 15th cetacean to become entangled in protective netting near the coast of eastern Australia in the current year, and the first marine animal that has perished, believed to have drowned during its travel toward the south.

Finding and Action

A representative for the government body of primary industries and regional development explained that netting crews found the deceased calf during a routine inspection on Tuesday morning.

No earlier notifications any calls of a whale entanglement near Coledale before this incident,” the official noted, further stating that no other marine mammal incidents in NSW shark nets were recorded so far this year.

But, during June, a marine mammal got caught in a marine deterrent along the Newcastle coast.

State wildlife authorities, the Organisation for the Rescue and Research of Cetaceans in Australia and emergency responders arrived on scene later that day, finding the juvenile whale with mesh wrapped around its fluke and pectoral fin.

“Each participant made every effort to free the deceased whale,” stated Marine Rescue NSW inspector the responder.

Difficulties and Consequences

The strategy was to move the carcass to a site for removal out of the ocean,” the inspector explained. Earlier that day, “the mix of rough ocean weather and the nearby rocks and beach meant it was becoming unsafe for marine personnel to continue operations, so we were compelled to halt”.

The whale carcass drifted to land later that day. Marine experts explained: “At this stage, the reason for death is not determined and will stay uncertain until … a necrops is carried out.”

Protective Netting System Information

There are fifty-one marine barriers installed in the region, which are fitted with audible deterrents and “dolphin pingers”.

The devices “emit a sonic pulse that repels the mammals from the zone and minimizes the possibility of capture,” the official explained.

“The NSW government will continue to investigate new shark mitigation technologies designed to minimise harm to sea creatures and safeguarding swimmers.”

Demands for Action

This tragic incident sparked fresh demands for the NSW government to discontinue its netting system.

Legislator the MP remarked how “profoundly tragic to observe a young whale succumb this way, especially because its passing was entirely unnecessary”.

“Annually when the nets go in, we observe more whales and other animals including dolphins, threatened sea turtles and highly threatened shark species caught, harmed or killed.”

Expert Perspectives

Marine researcher, who researches marine mammals at Griffith University, explained there was little evidence to suggest that shark nets averted shark bites historically.

Wide-ranging extraction of sharks by shores as a mitigation measure” barely decreased danger, Meynecke explained.

Meynecke said juvenile cetaceans were at higher risk of capture and death.

“It is understood that they lack awareness the risks posed by netting.”

Marine mammals gain knowledge, learning to communicate on risky zones, Meynecke added.

A juvenile marine mammal “might rapidly feel terror and amid turbulent waters there exists the danger of death”.

Government Response and Alternatives

Greens senator Peter Whish-Wilson said in a statement: “Authorities can help ensure swimmer safety by supercharging investment in current solutions to outdated and ineffective nets and lines.

“Options consist of subsidising shark shield personal deterrent devices, observation initiatives, eco-shark barriers, shark-resistant gear, and enhancing awareness campaigns.

“A government study into shark risk mitigation recommended the federal government show national leadership on supporting such financing, but these recommendations were overlooked.”

The official further demanded the national authorities to eliminate a loophole in the country’s conservation rules that enables local marine elimination initiatives.

“Federal law facilitates the state-sanctioned animal cruelty that is occurring along the eastern shores through a dangerous and archaic EPBC exemption.

“Now is the period to terminate the planet’s most extended ocean elimination and halt this cruel government-sanctioned animal cruelty.”
