An immature whale calf has been discovered dead subsequent to becoming entangled in a protective barrier off the coast of NSW.

The juvenile calf was discovered trapped by mesh off the Wollongong coastline on Tuesday, in the sea between Coledale and Wombarra.

This occurrence represents the fifteenth marine mammal caught in marine barriers near the coast of eastern Australia so far this year, and the first marine animal that has perished, believed to have drowned while on its migration toward the south.

Location and Action

A spokesperson for the government body of primary industries and regional development explained that netting crews discovered the deceased marine mammal during a routine inspection this week.

“DPIRD did not receive any calls regarding a trapped whale at Coledale before this incident,” the official noted, and mentioned that no other whale entanglements in state netting had been reported in the current period.

However, during June, another whale was trapped in a shark drumline along the Newcastle coast.

Marine protection agencies, ORRCA and Marine Rescue NSW took action later that day, discovering the immature marine animal with net entwined with its fluke and pectoral fin.

“All responders did their utmost to release the deceased animal,” commented Marine Rescue NSW inspector Stuart Massey.

Challenges and Aftermath

The intention involved transporting the carcass to a area where it could be removed out of the ocean,” Massey noted. Shortly before 3pm, “the mix of unfavourable sea conditions and the nearby rocks and beach made it hazardous for the rescue team to remain there, so we were compelled to halt”.

The body drifted to land later that day. ORRCA said in a statement: “At this stage, the cause of death is unknown and won’t be confirmed until … a autopsy is performed.”

Marine Barrier System Information

There are 51 shark nets installed in the region, that include with audible deterrents and acoustic devices.

The equipment “produce a high-frequency sound wave that deters the cetaceans from the zone and minimizes the possibility of entanglement,” the DPIRD spokesperson said.

“The NSW government plans to examine advanced marine safety methods intended to lessen impacts on marine animals while ensuring safety for swimmers.”

Calls for Change

The whale drowning caused renewed appeals for the local government to discontinue its marine barrier initiative.

NSW Greens MP the representative stated how “profoundly tragic to observe a young whale perish in this manner, particularly since its passing was entirely unnecessary”.

“Every year when the nets go in, we see more whales and other wildlife such as dolphins, at-risk marine reptiles and critically endangered grey nurse sharks caught, harmed or killed.”

Expert Insights

Dr Olaf Meynecke, studying sea animals at Griffith University, explained there was little evidence to suggest that shark nets have stopped shark attacks historically.

Extensive elimination of marine predators along beaches as a mitigation measure” did little to reduce threat, the doctor noted.

The expert explained whale calves faced greater danger of capture and death.

“Research shows that they don’t recognize the hazards posed by netting.”

Marine mammals develop experience, acquiring communication skills on risky zones, Meynecke added.

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

Official Reactions and Options

Politician Peter Whish-Wilson commented: “Governments should support keep ocean-goers safe by increasing financial support in current solutions to old and inefficient nets and lines.

“These include funding personal shark repellents, shark spotter programs, sustainable marine protections, bite-proof wetsuits, and enhancing awareness campaigns.

“An official investigation on marine safety advised national authorities show national leadership on supporting such financing, but this has so far been ignored.”

Whish-Wilson also called on the central government to eliminate a loophole in the federal protection legislation that allows local marine elimination initiatives.

“Government regulations allows the officially permitted marine mammal suffering that we’re seeing along the eastern shores via hazardous and outdated protection bypass.

“Now is the period to terminate the global lengthiest sea creature removal and stop this barbaric officially permitted creature suffering.”
