UPDATE, DEC. 17, 2014
A news release sent out yesterday by the Canadian Department of Fisheries and Oceans confirms what Ken Balcomb suspected when I interviewed him on the day the necropsy was performed. See also Associated Press story by reporter Phuong Le.
Ken Balcomb of the Center for Whale Research has written an excellent report about the recent death of J-32, the Southern Resident orca that died with an unborn and decomposing offspring inside her.
Ken’s report talks not only about his observations of the necropsy, which I reported in Water Ways on Saturday, but it also includes his observations as he watched the young whale grow up:
“The decade around the millennium was a difficult time for the J10 matriline – J32’s mom (J20) died at the age of seventeen in 1998 when J32 was only two years old; her grandmother (J10), who took over her care, died at the age of thirty-seven in 1999, when J32 was only three years old; and her uncle (J18) died at the age of 23 in 2000. All died young relative to the average lifespan of 50+ for females and 29 for males in this species.
“Fortunately, auntie J22 at age thirteen gave birth to a baby (J34) in 1998, and provided orphaned J32 the required nurturing of a ‘mom’. With that nurturing from grandmother and auntie, including perhaps a little milk, J32 made it through her infancy and into her teens to be a very vivacious young whale, full of energy.”
Ken writes eloquently about his concerns regarding the high levels of toxic contaminants carried in the blubber of the Southern Resident orcas. The contaminants are known to cause problems with the immune and reproductive systems. They also can cause brain deficits that can lead to behavior disorders. He writes:
“These pollutants are released to circulate in the bloodstream when the whales’ blubber fats are metabolized for energy when fresh food is scarce. It is like having a freezer full of tainted and freezer-burned food that you never have to eat unless there is nothing in the grocery store. When nothing else is available the bad stuff is taken out of storage and circulated for body needs.”
Ken also repeats his plea for people to take action in the face of ongoing disaster for the local killer whale population — including this sudden death of a young mother known as Rhapsody and her unborn offspring.
“This is a very ugly situation for the population of Southern Resident killer whales – our beloved orca. I think we must restore abundant healthy prey resources ASAP if these whales are to have any chance of avoiding extinction. The critical point for their recovery may already have passed. I hope not, but it will soon pass if we do not take immediate action.”
Ken’s full report is well worth reading. It can be found on the website of the Center for Whale Research or you can download the title, “Preliminary Necropsy Report for J32” by Kenneth Balcomb, Center for Whale Research.
