A juvenile marine mammal has been located dead following getting trapped in a shark net near the beaches of New South Wales.

The juvenile whale was found trapped by barriers in northern Wollongong waters earlier this week, in the waters separating Coledale and Wombarra.

This event is the 15th cetacean caught in marine barriers off Australia’s east coast this year, while being the initial whale that has perished, presumed to have been suffocated during its travel to Antarctic waters.

Discovery and Reaction

A spokesperson for the state department overseeing marine activities stated that marine safety teams located the lifeless marine mammal while conducting a regular examination this week.

There were no prior reports any calls of a whale entanglement in the Coledale area earlier,” they said, adding that no additional whale entanglements in coastal barriers were recorded this year.

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

State wildlife authorities, marine rescue organizations and emergency responders took action on Tuesday afternoon, discovering the juvenile whale with net tangled around its tail and side fin.

“All responders made every effort to disentangle the deceased cetacean,” commented rescue official Stuart Massey.

Obstacles and Aftermath

“The plan was to take the carcass to a location where extraction was possible from the sea,” Massey noted. Earlier that day, “the situation of rough ocean weather and the closeness to rocky areas and coast created dangers for marine personnel to remain there, so we were obliged to stop”.

The whale carcass washed ashore on Tuesday night. The organization stated: “At this stage, the cause of death is unknown and will remain unclear until … a necrops is conducted.”

Shark Net System Information

Currently deployed are over fifty nets deployed in NSW, that include with audible deterrents and acoustic devices.

The devices “produce a sonic pulse that discourages the marine animals from the vicinity and lowers the risk of entanglement,” the DPIRD spokesperson noted.

“State authorities plans to examine advanced marine safety methods intended to lessen impacts on marine animals while protecting swimmers.”

Demands for Action

The calf’s death caused renewed appeals for the local government to discontinue its marine barrier initiative.

Politician Cate Faehrmann said it was “absolutely heartbreaking to see a baby humpback whale perish in this manner, notably as its demise was entirely unnecessary”.

“Every year during net installation, we see additional cetaceans and other animals like dolphins, endangered loggerhead turtles and highly threatened shark species ensnared, wounded or deceased.”

Specialist Perspectives

Marine researcher, studying marine mammals at the institution, said data is limited to show that marine barriers have stopped marine incidents in the past.

Extensive elimination of sharks along beaches as protective steps” did little to reduce risk, Meynecke explained.

The researcher stated young whales were at higher risk of entanglement and drowning.

“We know that they are not aware of the dangers from barriers.”

Marine mammals develop experience, understanding how to share on risky zones, he said.

An immature cetacean “could easily become distressed and amid turbulent waters there is the risk of death”.

Government Reactions and Options

Greens senator the official said in a statement: “Authorities are able to assist ensure swimmer safety by increasing financial support in contemporary options to old and inefficient nets and lines.

“Alternatives involve funding personal shark repellents, shark spotter programs, sustainable marine protections, protective swimwear, and bettering informational efforts.

“A government study on marine safety suggested central government show national leadership on driving this investment, but this has so far been ignored.”

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

“Federal law enables the government-approved harm to wildlife that is happening along the eastern shores using risky and old-fashioned protection bypass.

“Now is the period to terminate the planet’s most extended ocean elimination and cease this inhumane state-approved wildlife harm.”
