Did anyone see Migaloo?
Did any Ballina Shire whale-watchers see Migaloo the white whale pass by this week? If so, Ballin Info would love to hear of your experience.
Migaloo was sighted off Evans Head on Tuesday and Burleigh Heads on Wednesday.
It was off Ballina in October 2004 that Migaloo was genetically identified by Southern Cross University (SCU) researchers as a male.
During surveys of the Ballina Whale Research Project in October 2004, SCU researcher Dan Burns and his team obtained sloughed skin samples of Migaloo as he passed Ballina, on his return journey to the Antarctic.
The DNA samples were then tested by PhD student Megan Anderson who found that Migaloo and his travelling companion were both males.
SCU Whale Research Centre director Professor Peter Harrison said then that he believed this was the first time genetic samples from an apparently albino whale or dolphin had been collected anywhere in the world.
“It was always assumed that Migaloo was a male, but we had not been able to confirm that until now,” Professor Harrison said.
“From the skin samples we will also be able to see how he is related to the rest of the humpback population.”
Dan Burns, a PhD student at SCU’s Whale Research Centre, collected the sloughed skin samples that were left floating on the sea surface after the whales had passed.
Meanwhiel, as Migaloo makes his way north during the annual migration of humpback whales along Australia’s east coast, researchers have issued a renewed call for extreme care around all whales.
The Southern Cross University Whale Research Centre is urging people to heed the special exclusion zone which applies to Migaloo. The regulations mean no one can bring a boat or jet ski closer than 500 metres or fly an aircraft within 2000 feet of the whale.
Wally Franklin, a researcher with the Centre and co-director of The Oceania Project, said the intense interest in Migaloo, an all-white whale, put him at increased risk.
“People need to make sure they adhere to the regulations, which are in place to protect Migaloo. We also need to make sure people are aware of the general regulations in regard to all whales. With the population of humpbacks increasing, there is a greater risk of boat strikes,” Mr Franklin said.
“We are seeing more incidences of that kind of damage to whales, where you can see the marks left by a propeller. We share the near-coastal waters with whales and dolphins and we need to take particular care when in the water.”
Mr Franklin said while most humpback calves were born in the waters off Queensland, some were born earlier in the season and had to make the trek along the coast.
“These young whales are at quite high risk until they reach the protected waters off the Great Barrier Reef. If anything occurs to interfere with the relationship with their mother, they become very vulnerable,” he said.
“Boat strikes and entanglement in fishing lines are among the threats.”
There have been a number of strandings already reported along the coast. People who find stranded whales or dolphins are also being reminded to immediately contact relevant authorities and report the location of the stranding and not attempt to the put animals back in the water.
“Injury and illness are two of the primary causes of strandings. Prior to doing anything, people should seek advice as quickly as possible,” Mr Franklin said.
“Anyone who sees a whale or dolphin in distress, or a stranded animal, should contact the National Parks and Wildlife Service and take extreme caution until help arrives.”
