As the humpback migration season starts, not all whales will arrive unharmed

Key Points
  • The eastern bultback whale migration season has started along the east coast of Australia.
  • Every year at least 32 whales get caught in fish equipment that authorities want to prevent.
  • True figures of whales that were injured during the migration season are supposed to be even higher.
In December last year, a young humpbacks were dead on an NSW beach.
It was trapped in the fishing rope and drives and became exhausted when it tried to swim the route of his annual migration along the east coast of Australia.
Despite the fact that rescue teams avoid it, it died days later.
Dr. Olaf Meynecke, a marine scientist at the University of Griffith, said that the whale was in a bad way after he was imprisoned.

“It was pretty clear to see from the images that this was an animal that had really starved for a few weeks, it was pretty thin and it was also covered with seashouses that usually multiply fairly quickly when those whales start to slow down,” he said.

Meynecke said that more needs to be done to prevent whale permits.

In the past five years, the New South Wales National Parks and Wildlife Service said that it had received an average of 32 reports of confused whales per year.
More than 80 percent of those complications included fishing and floats.

Meynecke said that this is only the number of whales that people have encountered, and the true figure is probably double.

Commercial fishermen such as Mitch Sanders want to do something about it.
A valvisser that mainly works from Terrigal and beautiful beach on the NSW Central Coast has joined Sanders with a program run by Oceanwatch Australia with the reduction of whale -stringing risk through fish equipment.
“We don’t want any complications either, we lose our equipment, it takes us time and money to get the equipment back,” he said.

So ” [we want to do] Whatever we can do to work next to the whales, because they are not going anywhere, so we have to make sure that we are viable and ensure that we can do what we can do to prevent complications. “

New technologies

Sanders tastes new technologies such as a Ropeless attachment for his traps, designed in the United States.
Instead of letting a rope run through the ocean, the device contains rope in a metal cage, which is only released as soon as the fisherman activates it to unlock electronically so that they can pick up the fall.
However, the devices are expensive and Australian fishermen work differently than their American counterparts.
“It works, it is very good, but it is cumbersome and very time -consuming, and while we perform a few traps on each rope, they run up to 40 falling on one rope,” said Sanders.

“So, if it takes a little longer to get that first to the surface, it’s not so bad, but if we have to do it for every fall, it makes it a bit difficult.”

Humpback whale populations along the east coast of Australia have been considerably recovered because whaling was forbidden, which increases a few hundred in the 1960s to around 40,000 today.
Oceanwatch CEO Lowri pryce said it means that the oceans are extra busy.

“The fishermen are very aware of the number of whales that increases for many, many years. We look very much at coexistence, we want the whales to migrate safely, have a safe passage, but we also want fishermen to have a safe passage,” she said.

Pyce said as part of the program that Australian fishermen are talking with their international counterparts, especially those in the US, Canada and Nieuw -Zeeland.

“We really try to detect as many ideas as possible and then make contact and transfer people so that we can adjust. Every operation is very different, so it’s really important to have that series of different gears,” she said.

Calls for consistent fishing regulations

Fishing instructions vary throughout Australia, but scientists such as Meynecke call for a uniform approach to prevent whale permits.
“There have been some smaller projects to tackle it, but there is no major attempt to actually reduce the entanglement and the rise of these complications,” he said.
Passionate citizens such as Steve Trikoulis have been performed.
He is the vice-president of the organization for salvation and research of cetaceans in Australia, a non-profit organization that focuses on saving and protecting marine mammals, including whales.

“In general, what happens is that you will see a whale violation or do a blow or something like that, but what we are looking for is like a leading path behind the whale, because that gives us an indication that something is entangled,” he said.

Meynecke said that changes in the fishing industry are important, and calls for more research into making mitigation technologies more accessible.
“If people were more aware of the fact that we actually have quite a few whales that are entangled in gear and that this is an ethical care, but also just a care for animal welfare for us to ensure that this does not really happen in the future.”
