Whale migration season has come once more to the East Coast with the primary sightings being reported. Every yr presently, humpback whales migrate from feeding grounds within the Southern Ocean to the nice and cozy waters of the Coral Sea to breed and provides beginning to their younger.

Queensland will welcome these mild guests with a gauntlet of 27 gillnets set with the intention of decreasing the danger of shark chew. Eighty-one whales have been entangled in shark nets since 2001. In extra lucky cases the place an entangled whale is ready to be freed, there isn’t any assure they’ll survive accidents from the ordeal. Such an occasion is extraordinarily traumatic for the already exhausted migrants.

A trial substitute of shark nets with options in Queensland waters at some stage in the whale migration was really useful to the Minister for Agriculture and Fisheries, Mark Furner, by the Shark Control Program’s Scientific Working Group in September 2020. The Working Group is a panel of shark specialists tasked with guiding this system and offering recommendation to the Minister’s Office.

However in 2021, Minister Furner said publicly that eradicating the shark nets for the whale migration was off the desk regardless of the scientific recommendation from his Working Group. His workplace wouldn’t affirm if web elimination through the whale migration was doubtless in future years.

“Every year, like clockwork, the sharks nets risk entangling migrating humpback whales and the public can only watch on in dismay,” mentioned Humane Society International marine biologist Lawrence Chlebeck.

“The Minister’s personal scientific specialists suggested him to trial a elimination of the nets through the whale migration season. Each yr that the recommendation just isn’t acted on will solely see extra whales entangled.

“It makes no sense because everyone knows the nets are outdated and not effective at reducing the risk of shark bite to humans. All they do is cause unnecessary injury and death to migrating whales and other precious wildlife.”

Dr. Leonardo Guida, shark scientist at Australian Marine Conservation Society mentioned: “It’s incredibly frustrating seeing the same thing unfold each year when we have solutions that modernize beach safety standards and don’t put wildlife at risk. The drones are proving their worth on south-east Queensland beaches; keep them up and get the nets out now.”

Shark nets are put in on seashores on the Gold Coast, Sunshine Coast, Rainbow Beach, and Mackay as part of Queensland’s Shark Control Program. Though meant to cut back the danger of shark chew, the nets catch large numbers of non-goal species and can’t hold sharks from shore, offering nothing greater than a false-sense of safety.
