An juvenile marine mammal was found deceased after becoming entangled in a shark net off the coast of NSW.

An eight-meter calf was found trapped by barriers in northern Wollongong waters on Tuesday, in the waters separating Wombarra and Coledale.

This event represents the 15th whale trapped in protective netting near the eastern Australian coastline this year, and the first marine animal confirmed dead, presumed to have succumbed to drowning amid its journey toward the south.

Discovery and Response

A representative for the NSW department handling fisheries and regional matters mentioned that marine safety teams located the dead calf during a standard check early Tuesday.

No earlier notifications any calls about a caught cetacean at Coledale before this incident,” the official noted, adding that no additional cetacean traps in state netting were notified this year.

But, earlier this year, a marine mammal got caught in a marine deterrent off Nobby’s beach.

Marine protection agencies, marine rescue organizations and coastal rescue teams arrived on scene on Tuesday afternoon, discovering the immature marine animal with mesh entwined with its rear and side appendages.

“Everyone involved did their utmost to free the lifeless whale,” commented Marine Rescue NSW inspector Stuart Massey.

Challenges and Aftermath

The strategy was to take the remains to a site where it could be removed out of the ocean,” the inspector explained. Shortly before 3pm, “the situation of adverse marine environment and the closeness to rocky areas and coast meant it was becoming unsafe for our vessel and crew to remain there, so we were compelled to halt”.

The remains washed ashore that evening. The organization stated: “Currently, the fatality cause is not determined and will stay uncertain until … a necrops is conducted.”

Marine Barrier System Information

There are over fifty nets installed in the region, equipped with acoustic “whale alarms” and acoustic devices.

These tools “produce a high-pitched acoustic signal that discourages the mammals from the zone and reduces the chances of trapping,” the representative said.

“The NSW government will continue to investigate modern deterrent systems intended to lessen impacts on marine animals while protecting swimmers.”

Calls for Change

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

NSW Greens MP the representative stated that it was “profoundly tragic to observe a baby humpback whale succumb this way, particularly since its demise was entirely unnecessary”.

“Every year during net installation, we see additional cetaceans and other wildlife such as dolphins, endangered loggerhead turtles and critically endangered grey nurse sharks ensnared, wounded or deceased.”

Specialist Insights

Marine researcher, who researches sea animals at the university, commented data is limited to show that protective nets had prevented marine incidents in the past.

Extensive elimination of ocean hunters by shores for safety reasons” did little to reduce threat, he said.

Meynecke said young whales faced greater danger of capture and death.

“We know that they lack awareness of the dangers posed by netting.”

Marine mammals gain knowledge, acquiring communication skills on risky zones, he said.

An immature cetacean “might rapidly feel terror and if you’ve got high seas there exists the danger of death”.

Political Response and Alternatives

Greens senator the senator commented: “Officials can help protect marine visitors by supercharging investment in modern-day alternatives to archaic and useless marine barriers and deterrents.

“Alternatives involve supporting shark shield personal deterrent devices, shark spotter programs, environmentally friendly barriers, protective swimwear, and bettering informational efforts.

“A government study regarding ocean threats suggested central government show national leadership on supporting such financing, but these recommendations were overlooked.”

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

“Government regulations enables the officially permitted marine mammal suffering that we’re seeing near Australian beaches via hazardous and outdated protection bypass.

“The moment has come to terminate the world’s longest marine cull and cease this inhumane government-sanctioned animal cruelty.”
