An immature whale calf has been discovered deceased after being caught in a protective barrier off the coast of NSW.

An eight-meter marine creature was discovered trapped by netting off the Wollongong coastline earlier this week, in the sea between Coledale and Wombarra.

This event is the fifteenth marine mammal caught in marine barriers off the coast of eastern Australia this year, and the first marine animal that has perished, thought to have drowned during its travel toward the south.

Finding and Reaction

A spokesperson for the NSW department of primary industries and regional development stated that marine safety teams found the dead whale in the course of a regular examination early Tuesday.

“DPIRD did not receive any reports about a caught cetacean near Coledale before this incident,” the spokesperson added, adding that no other marine mammal incidents in state netting were notified this year.

But, during June, a whale became tangled in a marine deterrent along the Newcastle coast.

Marine protection agencies, ORRCA and Marine Rescue NSW arrived on scene that afternoon, discovering the immature cetacean with net tangled around its tail and side fin.

“All responders did their utmost to release the dead whale,” stated coastal authority the inspector.

Challenges and Consequences

The intention involved transporting the body to a location for removal from the water,” he said. Earlier that day, “the mix of adverse marine environment and the nearby rocks and beach made it hazardous for marine personnel to continue operations, so we were forced to abandon”.

The whale carcass washed ashore that evening. The organization stated: “At this stage, the fatality cause is not determined and will remain unclear until … a autopsy is conducted.”

Shark Net System Information

There are fifty-one marine barriers set up along the coast, that include with sound-based alerts and “dolphin pingers”.

These tools “send out a high-pitched acoustic signal that discourages the mammals from the zone and minimizes the possibility of capture,” the representative said.

“State authorities is researching new shark mitigation technologies aimed at reducing effects on ocean life while protecting swimmers.”

Appeals for Reform

The calf’s death caused renewed appeals for the state authorities to end its marine barrier initiative.

Legislator Cate Faehrmann remarked it was “profoundly tragic to witness a baby humpback whale die like this, particularly since its passing was completely avoidable”.

“Every year when the nets go in, we observe more whales and additional creatures such as dolphins, threatened sea turtles and highly threatened shark species ensnared, wounded or deceased.”

Researcher Insights

Marine researcher, who researches ocean creatures at Griffith University, said there was little evidence to show that shark nets had prevented shark attacks historically.

The “large-scale removal of ocean hunters near coastlines for safety reasons” did little to reduce threat, the doctor noted.

The expert explained whale calves were more vulnerable of being trapped and suffocating.

“We know that they lack awareness the risks of nets.”

Cetaceans learn over time, acquiring communication skills regarding hazardous areas, the researcher noted.

A young whale “could easily become distressed and with rough ocean conditions the possibility arises of suffocation”.

Official Reactions and Options

Greens senator the official stated: “Officials can help keep ocean-goers safe by supercharging investment in contemporary options to archaic and useless marine barriers and deterrents.

“These include funding personal shark repellents, shark spotter programs, eco-shark barriers, protective swimwear, and improving public education.

“A government study regarding ocean threats suggested central government show national leadership on promoting these funds, but this advice was not followed.”

Whish-Wilson also called on the central government to remove an exemption in the national environment law that permits state-controlled shark cull programs.

“Government regulations facilitates the government-approved harm to wildlife that is occurring along the eastern shores through a dangerous and archaic EPBC exemption.

“The moment has come to terminate the planet’s most extended ocean elimination and cease this inhumane government-sanctioned animal cruelty.”
